Ronald Bailey | February 15, 2007
Columnist George Will weighs in on the economics of climate change:
Climate Cassandras say the facts are clear and the case is closed. (Sen. Barbara Boxer: "We're not going to take a lot of time debating this anymore.") The consensus catechism about global warming has six tenets: 1. Global warming is happening. 2. It is our (humanity's, but especially America's) fault. 3. It will continue unless we mend our ways. 4. If it continues we are in grave danger. 5. We know how to slow or even reverse the warming. 6. The benefits from doing that will far exceed the costs.
Only the first tenet is clearly true, and only in the sense that the Earth warmed about 0.7 degrees Celsius in the 20th century. We do not know the extent to which human activity caused this. The activity is economic growth, the wealth-creation that makes possible improved well-being—better nutrition, medicine, education, etc. How much reduction of such social goods are we willing to accept by slowing economic activity in order to (try to) regulate the planet's climate?
Whole Will column here.
And in his column, my friend Jonah Goldberg looks at trading off wealth against warming and decides on wealth:
Earth got about 0.7 degrees Celsius warmer in the 20th century while it increased its GDP by 1,800 percent, by one estimate. How much of that 0.7 degrees can be laid at the feet of that 1,800 percent is unknowable, but let's stipulate that all of the warming was the result of our prosperity and that this warming is in fact indisputably bad (which is hardly obvious). That's still an amazing bargain. Life expectancies in the United States increased from about 47 years to about 77 years. Literacy, medicine, leisure and even, in many respects, the environment have improved mightily over the course of the 20th century, at least in the prosperous West.
Given the option of getting another 1,800 percent richer in exchange for another 0.7 degrees warmer, I'd take the heat in a heartbeat.

I would, too. So let's turn off the heat now.
Oh...that's right
Typing at a computer contributes to global warming --
significantly less than Nancy Pelosi's jet -- but some
nevertheless.
Agree with my views, damnit! Slow global warming by not typing a
response.
Uh, never mind my last post, I misunderstood what Goldberg was
saying.
What he was saying was actually stupider than what I thought,
considering the whole problem is that the earth is warming much
faster now than what it did on the whole of the last century.
Nancy Pelosi reminds me of Ilsa, the Bitch of Buchenwald. There is already a Democratic Socialist Caucus in the US House. Perhaps she should start a National Socialist Caucus
What were the odds that a thread beginning with:
Now discuss, hector, posture, call people names, whatever.
would quickly attract a Godwin response?
since we don't know all the costs yet (or the benefits), Goldberg's conclusion is tentative at best
What I'd like to see is the creation and dispersion of
technology that would make life livable in the event of whatever
runaway-heating/farting effect we may undergo, since that is the
real worry here.
Specifically, biodomes and oxygen generaters.
We should probably also create a database of all the various DNA
layouts of animals and plants, in the event of a planet-wiping
catastrophe. I thought a few activities were already taking place
in the form of time capsules, but maybe we should make a few copies
and store some on the moon.
Also, Dan is a different sexual persuasion blah blah blah.

Cuz it really is a simple tradeoff, just like the world renowned
Climatologist J. Goldberg says it is.
Wonder what the folks who actually stand to lose something in this
bargain would choose, say, the residents of the Maldives. Wonder
how much wealth they have? I bet theyve made a little in tourism.
Wonder how much CO2 their activities create? Think anyone will ask
them? Dr. Goldberg?
Disclosure: I have never been to the Maldives, nor am I married
to one. But it did look nice in a magazine* picture I saw.
* made from 100% post recycled materials.
I do think the issue of climate changes does tend to be treated
in an alarmist
fashion (maybe that's necessary to get
people's attention), but that doesn't mean it isn't a real issue
worth addressing.
Global warming is probably a real, man-made phenomenon. It will
have some positive effects, some neutral effects, and plenty of
negative effects that will cause concerns. While there are some
conservationist measures that can be taken to mitigate some of the
effects of global warming, there probably isn't very much we can do
about it for the
time being.
As Will points out, Greenhouse Gases = Wealth
Creation. Europe and the USA (more so in the U.S., because we are
more wasteful) can manage a marginal reduction in greenhouse gas
output through efficiency and conservation, but this won't really
tackle the problem. Further, the developing world's emission of
greenhouse gases is increasingly very rapidly (China is already
number 2 in the world after the U.S., and will soon be number 1).
Countries emit more as they
get richer, and since most of the world's people are in poor
countries, I just don't see any way around increased
emissions.
Without increasing emissions, at least for the time being,
developing countries would not be able to lift their people out of
extreme poverty, and the rich world would not have the
resources to pursue technological innovation to
improve people's lives. Ultimately, the solution has to lie in
technology. In 50
years or so, we should see renewable fuel cells that will be able
to power everyday life the way fossil fuels do now.
Until then, we will just have to put up with global warming
(granting, of course, reasonable efforts to slow it down). Luckily,
it should be manageable. We are looking at a couple of degrees
average temperature
increase over the next hundred years, not the
extinction of the human race. Yet very poor countries will likely
fare the worst (I can think of Bangladesh), so I do think the rich
world has a moral obligation to contribute to alleviate the
suffering of those harmed by global warming (Particularly if
further evidence develops of direct human causality).
Still, we can expect a lot of posturing on this issue, beginning
with Kyoto, a treaty which promises both too much and too little.
Too
much, because the goals are too unrealistic and will be unmet. Not
even by Europe. Too little, because (as is widely accepted) even if
Kyoto's targets were met in full, global warming would continue
unabated because the developing world (which accounts for most
of
the growth in emissions) is not included in the
treaty.
I like to procrastinate. Everyone should follow my lead and do nothing about global warming until we absolutely, positively have to do something.
I'm kind of puzzled why we "ought" to do anything -
1) Climate change is going to occur whether we try to influence it
or not.
2) Most of the "problems" really amount to changes in the utility
of land: land that was good for farming maple trees will now be too
hot for maple trees, but suitable for growing corn etc. Land that
made a good port will become inundated (converting other inland
areas to good port land) etc.
As the utility of the land changes, there will be profit
opportunities for entrepenaurs to take advantage of the changing
conditions. So let's say that the traditional maple tree habitat
starts to lose maple trees. The scarcity will prompt prices to go
up. The higher prices will encourage some bright fellow to start
planting maple saplings in what was former tundra. Meantime some
other fellow starts planting banana trees in southern
Vermont.
The "cures" promoted by politicans for the "ills" of gloabl warming
strike me as curing a chest-cold by blowing a guy's lungs out of
his chest with a howitzer. The real comedy is that the Earth's
climate is probably not controllable, and so our efforts to freeze
things in their current state will probably be wholly
ineffectual.
Come to think of it, given the usual audience for Will and Goldberg, the takeaway point of both columns probably is supposed to be "0.7 degrees! That doesn't sound like much, what are we so worried about?"
Dan T.,
Why do you think that the Earth cooled so
quickly between 1940 and 1970?
As the NAS report and the article in Newsweek both indicate, scientific knowledge regarding climate change was more uncertain than it is today. At the time that Rasool and Schneider wrote their 1971 paper, climatologists had not yet recognized the significance of greenhouse gases other than water vapor and carbon dioxide, such as methane, nitrous oxide and chlorofluorocarbons.[28] Early in that decade, carbon dioxide was the only widely studied human-influenced greenhouse gas. The attention drawn to atmospheric gases in the 1970s stimulated many discoveries in future decades. As the temperature pattern changed, global cooling was of waning interest by 1979
Great point, Matt! Let's fuck our economy to save the Maldives. What an ingenious policy!
laricot,
I don't think that "greenhouse gasses = wealth" so much as "a
certain state of economic development = greenhouse gasses". My
concern is that attempting to address the problem by arresting
economic development will worsen the problem and will prevent the
economic progression that will result in an enduring solution. I
consider the overpopulation scare to be a comparable analogy.
Matt: Yeah, that part really jumped out at me, too. What
Goldberg seems to imply is that all the purported calamities
associated with global warming are just a matter of people not
wanting to change into short sleeves.
It reminds me of the scene in This is Spinal Tap when
they're fielding criticism of a sexist album cover: "What's wrong
with being sexy?"
p.s. I have no strong opinions about Global Warming. I'm just
fascinated by idiots.
Dan T.,
So, was there cooling or not? If you're saying not because the
science wasn't up to accurate measuring, how can we reliably say
that temperatures have risen if we can't say accurately what they
were?
I may have misunderstood you.
Sure it's better to be warmer and 1800% richer, but that's on average. When you get down to particulars, in this instance maybe a lot of people get richer, but a lot of people also get f*cked. By like drowning or being killed in hurricanes or seeing their property destroyed. Sure those of us on the wealthy end are probably more likely to win out (as is kinda typical) but does that make the debate so obviously stupid or one-sided?
we should be glad this is where the know-nothing consensus on
global warming is inevitably going to go ("maybe it's not bad,
maybe we shouldn't try to stop it if it's expensive, (insert false
choice here)").
kind of like how they finally acknowledged that the US tortures
people ("but we need to! ticking bomb!")
now if we could get them to accept evolution ("but that doesn't
mean God doesn't exist!"). maybe even that emergency contraception
is the same as the pill ("ban them both!")
at least then the facts are resolved and the ideas can be
vetted
In the history of science have climate predictions of 100 years
out, or even 30 years out, or for that matter have any consensus
predictions covering more than a few decades ever been accurate?
Does anybody have an example?
That being said, I don't understand the insistence that a response
has to slow the economy. If a tax on consumption of buried carbon
was implemented & replaced some other tax, like income tax, how
would the economy suffer? There would be the same amount of drag on
the economy, but now there would be disincentives on fossil fuel
use in place of some of the disincentives we have now on every
productive activity. I don't see how, in total, there would be any
more economic drag than there is now.
Sure, most of the solutions thrown around would cause economic
costs, but it seems to me that there is a very simple solution that
would not.
Somebody please let me know where I'm wrong here.
Rick H.-
I know global warming is real because last summer I had to turn my
air conditioner all the way to 11. If we Americans don't do
something about this, it will be a black mark on our historical
record. It's so black you could ask "How much more black could it
be?" and the answer is "None more black."
Come on people, you're not even trying!
Ron throws out a post like that and you can't even make 30 comments
in the first half hour.
Geez. Slackers.
Just to keep the pot boiling, I'll suggest our alternatives are:
Allow the temperatures to rise until a technical solution is found
or cut the world population to around 100 Million. Tomorrow. Any
volunteers?
How did this post miss Fareed Zakaria's column, "Global
Warming: Get Used to It"?
Seems pretty relevant to the topic, and he's probably the only
other Newsweek columnist ever worth reading.
Ron, you should disclose if you own any part of George Will.
Let's make this real simple for you rocket scientists (Matt, Dan
& Krys)out there:
Warm (As in a degree) = Good
Cold(as in ice age) = Bad
We are told that those behind this hysteria, such as the European
Union, are basing their actions on the "science," if that is true
then why are they against every other "scientific" intervention
that would improve people's lives, such as DDT, GM foods, modern
healthcare (had to add that in).
If you think that carbon trading is anything other than a socialist
wetdream then you are dommed to a life of serfdom.
The warming here is pretty mild compared to Pluto
:http://web.mit.edu/newsoffice/2002/pluto.html
There is other evidence suggesting that global warming is occurring
on other planets as well.
If this is so, then perhaps the man-made causes are pretty
insubstantial, i.e. no matter how "green" we become, warming will
continue.
There is also "tree ring" evidence of very marked warmings and
coolings going back several hundred years.
Maybe Jonah Goldberg would like to stake a $1000 bet that he's
not clueless.
Oh wait, that didn't work so well with Iraq either.
Wonder what the folks who actually stand to lose something
in this bargain would choose, say, the residents of the
Maldives.
Move.
Matt,
Thanks for not conflating unrelated issues. I really appreciate
that.
kebko,
A carbon tax would raise the cost of energy which would raise the
cost of everything, slowing economic growth due to general price
inflation. Unfortunately, since the income from the carbon tax
would very likely be targeted as a subsidy to other less
economically efficient nonnuclear energy sources, there wouldn't be
any money left over to remove other taxes. Since the noncarbon
nonnuclear energy sources are less economically efficient, they
would likely not have much of a downward effect on energy prices,
even after subsidies.
Carbon taxes will also make nuclear energy much more economically
attractive, for better or worse. Heavy investment in nuclear energy
probably will drive energy prices back down, but it will also make
nonnuclear noncarbon sources appear to be even more of a money pit
than before. Not a big loss unless you don't like nuclear
waste.
aspendougy,
That's just crazy talk. Haven't you heard, EVERYONE knows what is
causing this, and no other possible explanations will be
heard.
Frankly, I'd listen to the human-caused global warming brigade more
closely if they did a better job of having intelligent people speak
for them instead of the "DENIERS ARE NAZIS" contingent.
TPG,
Bailey was Will's punk in Chino. Will owns Bailey's ass, not vice
versa.
BTW, Will doesn't even have the common decency to offer a reach
around.
Goldberg was everybody's bitch.
"If a tax on consumption of buried carbon was implemented &
replaced some other tax, like income tax, how would the economy
suffer?"
LOL
Do you really think that is what would happen?
Since when has any government ever replaced any major tax
collection system with another one? Any carbon tax would most
likely be a new tax on top of all the existing one's we have
already.
Remember when Hit & Run used to link to spiked often? Recently, they had a nice column on what I just posted about.
"If a tax on consumption of buried carbon was implemented
& replaced some other tax, like income tax, how would the
economy suffer?"
You honestly think they'd replace one tax with another?
Bailey was Will's punk in Chino. Will owns Bailey's ass, not
vice versa.
We need full disclosure on this. If we don't have it, the planet is
going to melt. All Maldivians will die.
jf,
Ack!! Brendan O'Neill!! I'll admit that that Spiked article is
better than most of what he wrote for Reason at least, even if it
is way too long.
"Global warming is probably a real, man-made phenomenon."
No doubt the very reason the ice-caps are also melting on
Mars.
- EZORB7
PS BTW we Martians are the center of the universe and damn proud of
it!
Getting back to Goldberg for a moment, I think he may be in
error when he declares that there is a direct ratio between global
warming and economic growth. It's more likely that you run into the
law of diminishing returns: the first 900 percent of economic
growth might only raise the temperature .1 degree. So the real
question is: would you trade half the growth in global warming for
a ten percent reduction in global GDP if that were the option? What
would be the total cost comparison between the two?
Rimfax: a general trend over a long period is generally more
significant than fluctuations within that period. Using your logic,
the fact that GDP declined between 1929 and 1932 is proof somehow
that it hasn't truly risen at all over the last hundred years.
Another recent article on Spiked comes to mind:
http://tinyurl.com/2lubpf
"This essay questions the views of African development implicit in
the 'adaptation agenda' and suggests that its implementation will
institutionalise African poverty and dependency. Those who suggest
that this agenda is empowering are not only patronising African
people but also seeking to exploit African poverty to reinforce
climate change advocacy in the West itself."
To more directly answer Rimfax's question: S02 was likely the cause of global cooling in that period. We've greatly reduced S02 emmissions, as it reduced air quality and was associated with acid rain. Yes, some people have suggested releasing significant amounts of S02 to combat global warming in a last ditch effort should the need ever arise. I believe we had a thread on this some weeks or months ago.
James,
So, if man made CO2 causes global warming, the modestly rapid
cooling over a 30 year period well into the industrial age, after
50 years of minimal warming, is analogous to 10 years of disastrous
economic policy? Can you help me out a bit with that analogy?
I am going to re-post my Slashdot
(http://science.slashdot.org/comments.pl?sid=221960&cid=17983626)
post here (edited for "grammer" and clarity):
"One of the great insanities of the modern age is the fact that
environmental problems get treated like sins, for which humanity
(Western civilization in particular) is expected to pay penance and
sacrifice exactly the essense of the society that we worked so hard
to built in the first place. What is sorely needed - and what I
push in my class - is a rational look at things that would treat
environmental issues as engineering problems: what (if anything)
can be done at the price the clients are willing to pay? And, no,
"humanity" is not the client here; those who push for action on
climate change, whatever their reasons might be, are.
On the last subject here, I would have taken climate change
alarmists a whole lot more seriously if they, expecting the rest of
the world to make sacrifices, were willing to make some sacrifices
themselves. No, giving up cars on their part wouldn't cut it, as
they already regard cars as evil - it has to be something of a
value. Let's see... I value personal transportation (that they want
me to give up), they value... let's say, old-growth forests. As
old-growth forests are essentially carbon-neutral, and tree farms
remove carbon from the atmosphere, are climate change action
proponents willing to sacrifice some of those forests to mitigate
global warming? Until I hear an honest "yes" from the "global
change is bad" camp, I'll remain unconvinced as to the severety of
the problem and opposed to any action that diminished my quality of
life."
The response by one "drix" was pretty indicative, too.
I wish smart people like Will wouldn't use the term "Cassandra" incorrectly. Cassandra did not just predict bad things, she predicted bad things AND WAS RIGHT.
I do think the issue of climate changes does tend to be
treated in an alarmist fashion (maybe that's necessary to get
people's attention), but that doesn't mean it isn't a real issue
worth addressing.
Wow, laricot, you actually have reasonable, balanced views about
global warming.
Chris S.,
That makes a lot of sense. However, why did the cooling begin over
30 years after the peak of the coal era and long after lower sulfur
and lower particulate fuels had taken over the economy? Most
industrialized cities had significantly reduced sulfur dioxide and
particulates by 1940.
Thanks for responding constructively.
aspendougy: man-made causes ARE pretty insubstantial, at least in regard to CO2. We (humanity) emit less than 4 whooping percent of the total release into the atmosphere. Bottom line - small tweaks of natural sinks would do a lot more good than huge (including complete destruction of the Western lifestyle) changes in human-associated sources.
Rimfax,
Yeah, it was pretty long, and in fact I was only about halfway
through when I posted it (I thought I was farther through and the
rest of the page was comments, shows what I know).
I don't remember him writing for reason. I guess I'll have to look
through the archives now.
Regarding question (2) posed by George Will, I don't see why
this elicits so much sarcasm and rage by so many people. Look, the
notion of a "greenhouse effect" on the whole has never really been
challenged. We are certain that some molecules absorb more infared
radiation than they reflect in other wavelenghts. The absorbed
radiation warms the planet via convection, and if molecules in our
atmosphere absorb more energy than they reflect, they should raise
the heat loss/gain equilibrium. Without these molecules, the planet
would be about 30c cooler.
We also know that CO2 (as well as H2O, CH4, O3 and a host of
others) fits this general description -- it absorbs IR radiation
and reflects relatively little light in other wavelenghts.
I understand that this paints an extremely simple picture of
climate change, but people have to understand that some degree of
global warming resultant from increased levels of CO2 is the
expected outcome. Empirical data confirms at least a
correlation between increased temperature and CO2 emmission, and we
have every reason to believe -- based on the CO2 light absorption
profile discussed above -- that we have causation as well. No, it's
not 100% percent certain, and we can't confirm this in a laboratory
or match global climate change with simple models -- the actual
atmosphere is too complex for such certainty.
Question (6), IMO, is the most complicated question posed by Will,
and I honestly doubt that anything short of a major technological
innovation will make the benefits worth the costs. But just a
little effort on the CO2 reduction front may buy us some time here.
It's at least worth thinking about.
Rimfax,
I don't know the answer to your second question, but yeah, that's a
fair question. I'd seach around google if I had more time
tonight.
jf,
O'Neill had two or three articles that elicited more groans than
Weigel and Young combined from their particular detractors. Not
that they were anti-libertarian or anything, but that they missed
any useful mark by such a wide margin.
The only one that I can recall at the moment was an article on PETA
that was so flip and dismissive of that often vile organization
that I almost wanted to send them a donation as penance for reading
it.
I just remembered his name after reading the second awful article.
He did have one excellent article, as well. I remember being
shocked that he wrote it.
James K
You missed the part that Cassandra was also cursed by Apollo: He
decreed that no one would ever beleive her prophecies.
That, of course, can be spun any way one chooses.
Socialism is what causes global warming. If the governments of the world would stop slowing progress through regulation and taxation we would develop clean technologies that make this whole debate moot.
Chris S.,
Thanks. I've searched before and I haven't found any good answers
regarding the offsets of pollution trends and warming/cooling
trends. Perhaps there is a causal link in there, since, as you
note, the understood behavior of the compounds in controlled
conditions says there should be. Maybe some complexity of the
atmosphere creates a multi-decade delayed response, such that even
the historical delayed correlation between temperature and CO2
really is a sign of causality rather than one of simple
correlation, as the CO2 delay implies. The trouble is that the
historical behavior of the global climate does not very closely
follow any of our models. We've declared the greenhouse gas model
to be close enough without really establishing any confidence that
it is any better model for prediction than astrology when it comes
to climate change causality.
Unfortunately, I fear that I am getting biased by the ideology of
so many of the global warming believers. I can accept that mankind
may be ruining this planet, but I am reflexively skeptical whenever
this is alleged followed immediately by recommendations for
Ludditism or Marxism.
"Those who suggest that this agenda is empowering are not
only patronising African people but also seeking to exploit African
poverty to reinforce climate change advocacy in the West
itself."
Another aspect of this, seen in California today, is the notion
that California will economically gain by being at the forefront in
the technologies that will allow the developing world to advance in
a carbon neutral way.
In other words, the very richest people on earth are guiding the
political will to restrict carbon emissions of all humanity,
including the poorest, with direct economic benefit back to
themselves.
It's rather sickening.
Well, I suggested that a carbon tax wouldn't be any more
damaging to the economy than most other taxes & asked to be
corrected. The only responses I got were 2 strawmen:
1) The new carbon tax wouldn't be matched by a tax cut.
and
2) The revenue from the tax would be wasted on a bunch of
subsidies.
Unfortunately, those weren't answers to my question. I still have
not heard a direct disagreement with my proposal. A new carbon tax
as a replacement for a comparable amount of income tax would
address the carbon problem without dragging on the economy.
I have never heard a direct rebuttal to this, yet I frequently hear
the issue addressed as if there is no way to address the problem
without dragging down the economy.
Anybody can think of ways in which things won't work, but if this
is a simple way for policy to work, then we should be advocating
for it. Otherwise, we're being dishonest.
And the solution isn't unreasonable:
1) Deals are done all the time where one tax is traded for
another.
2) The last major change in income tax policy was a tax cut - and
that was without a matching tax increase.
3) Energy prices have tripled in the last couple of years with very
little effect on the economy. There's nothing magic about energy
that makes taxes on it somehow more damaging than taxes against
anything else. If taxes were implemented that simply kept oil
prices near their current level, so that investments in long term
alternatives could be made without the risk of oil going back to
$25/barrel, we would have investment in alternatives like crazy
right now. Nobody's investing without subsidies now because the oil
companies are out drilling like crazy for new oil that is
$25/barrel or less, and the price of oil will eventually fall.
You'd be nuts to invest in alternatives now. But the price floor on
oil would make many alternatives viable without the need for
subsidies.
>It's rather sickening.
Yes, rather. But most Californians would respond to your argument
by saying "if we destroy the planet we'll destroy Africa too,
stupid." And you'd never get beyond that point.
I live in CA. I figure, if my town decides to start picking through
my garbage to see if I'm compliant with its recycling and
composting demands I'll probably just start taking my trash to the
dump myself (it's not far away). But if the state actually does
mandate fluorescent lightbulbs, I'm leaving.
Regarding "global cooling" in the middle decades of the 20th
century, I don't think there is a consensus any more than there is
consensus about exactly what percent of the current warming is
non-cyclical (80%? 120%?). We'd need to understand the world a lot
better than we do.
The candidates, considering what we know are (as mentioned
previously) SO2 and particulate matter emitted both by humans in
large uantities and by volcanoes in abnormally large quantities
during the decades in question. In hindsight the magnitude of the
cooling was mild compared to the warming trend.
For rimfax to consider, increased radiative forcing has to warm the
Earth's water before it can warm its land. And what with the high
specific heat of water (and the huge quantity of it), that takes a
long time and leads to significant lags between emissions and
warming.
kebko,
Not only do I agree with your take on carbon taxes, but I'm willing
to admit I'm a simpleton if someone can refute the arguments you
have made. I see no harm in enacting a revenue-neutral carbon tax;
indeed, as a tax on producers which would be directly passed on to
the largest users, I see a benefit. Far better to penalize people
who drive the hated gas-guzzling SUVs, or have mansions with huge
heating bills, than to give tax credits to oil companies and have a
social-engineering income tax.
kebko,
Sure, most of the solutions thrown around would cause economic
costs, but it seems to me that there is a very simple solution that
would not.
The problem is, you'll never ever get the politicians to just do a
one-up tax trade off. They'll end up keeping too much of the old,
while imposing all of the new. Like G.M. said.
Besides, you misunderstand the intent of the hard left greenies.
They want to hurt Western economics. West = BAD. You now,
like white men are there and they run everything, and all that crap
that has to be stopped.
Nonetheless, if you really could do a one-up tax trade, it might do
something towards creating incentives to get away from carbon. But
see comments above about nukes, because lots more nukes is a very
probable outcome of your proposal.
You should consider what impact the melt down of a single large
nuke plant might have on the environment, including the
atmosphere.
I for one am not convinced nukes are really a smarter alternative.
Maybe they are, but it would take decades and many dollars to find
out -- and by then, we wouldn't be in a position to back up and go
the other way again.
kebko,
You have a point. You weren't asking about the political
likelihoods and that's very fair.
So, if I understand your question correctly, what if carbon taxes
were placed on the importation or extraction of carbon releasing
fuels and other taxes, such as income, were reduced to offset
that?
It would raise the price of energy and subsequently other goods
that take energy to produce, but income net would increase as well,
probably offsetting each other. The net effect would likely be
somewhat regressive by socialist standards since the rich would be
able to afford energy saving technologies that the poor would not,
but the economy would eventually catch up and start scaling energy
saving technologies for mass purchase at Walmart and Target.
Overall, it would probably not be a bad bit of social engineering,
even aside from any global warming or carbon emission concerns. If
it could simplify the tax code, it could save even more, though it
would put a lot of tax preparers out of work.
Basically, I like the idea as a tax improvement measure and I'm
mildly enthused about it as an environmental measure.
Thanks for sticking with it for us.
Matt,
Yes, that is a very likely mechanism for the apparent extended
delay. I'd like to see some scientific backing for it. I won't be
surprised if that proves to be true.
However, it would also suggest that our current warming is due to
emissions released 30 years ago. For all we know, the reduction in
CFC emissions has already started a correction that we won't see
for another ten years or so.
You missed the part that Cassandra was also cursed by
Apollo: He decreed that no one would ever beleive her
prophecies.
That, of course, can be spun any way one chooses.
Global warming deniers are in the pocket of Big Apollo.
Hey guys (in the midwest gender-neutral sense), thanks for
reconsidering & responding to my suggestion.
I think the regressive issue is probably what would kill that
proposal with the Democrats. It would be a legitimate concern. But,
the income tax has been made so progressive that any reduction in
it is going to be extremely weighted to the wealthy. Nobody with
less than median income has a stake in that tax, which I consider a
real political problem. So, I think the issue is that the income
tax is too progressive.
Except for the very richest people, I don't know that energy cost
as a percentage of total cost of living is that different among
most citizens. I'm not convinced that it's that regressive. I
suppose the working poor spend more on gasoline, but, as has been
stated here, energy costs would find their way into practically
everything we spend money on.
If we're really worried about regressive taxes, we could stop
taking 12% of every persons income away from potential retirement
savings in order to fund "retirement savings". But, that's another
topic.
Dan T. and joe,
Have an afternoon to help me out with that six-pack for my 1972
Dodge Charger hybrid?
joe, when are you going to do some cut and paste work here? I
missed it if you did already.
Guy,

"The problem is, you'll never ever get the politicians to just
do a one-up tax trade off. They'll end up keeping too much of the
old, while imposing all of the new."
They wouldn't get rid of ANY of the old - just impose the new on
top of it.
The whole purpose of the politician's chicken little routine on
global warming in the first place is to convince individuals and
businesses that THEY need to sacrifice more money and freedom to
"solve" the "problem".
You can be sure that there is to be no sacrifice by the policitians
in giving up any power that they have now.
The federal income tax is a vehicle for massive wealth
redistribution and social engineering for any and every purpose
under the sun.
That enormous power begats campaign contributions, fawning
lobbyists, etc for the politicians.
There is no way they are going to give that up in exchange for a
single-purpose carbon tax.
A new carbon tax as a replacement for a comparable amount of
income tax would address the carbon problem without dragging on the
economy.
Perhaps. However, I still have a concern that any tax that is
ostensibly meant to discourage some human activity soon becomes a
stream of income that the government depends upon. It won't escape
the attention of some political players that reducing our
greenhouse gas emissions would shrink that income stream.
HOUSE HEARING ON 'WARMING OF THE PLANET' CANCELED AFTER ICE
STORM
HEARING NOTICE
Tue Feb 13 2007 19:31:25 ET
The Subcommittee on Energy and Air Quality hearing scheduled for
Wednesday, February 14, 2007, at 10:00 a.m. in room 2123 Rayburn
House Office Building has been postponed due to inclement weather.
The hearing is entitled "Climate Change: Are Greenhouse Gas
Emissions from Human Activities Contributing to a Warming of the
Planet?"
The hearing will be rescheduled to a date and time to be announced
later.
DC WEATHER REPORT:
Wednesday: Freezing rain in the morning. Total ice accumulation
between one half to three quarters of an inch. Brisk with highs in
the mid 30s. North winds 10 to 15 mph...increasing to northwest 20
to 25 mph in the afternoon. Chance of precipitation near 100
percent.
Wednesday Night: Partly cloudy. Lows around 18. Northwest winds
around 20 mph.
The idea that any warming is a result of human activity is
challenged by strong evidence to the contrary that includes a new
study published in Geophysical Research Letters in January that
found that: "the rate of sea level change was found to be larger in
the early part of last century." In the first half of the 20th
century sea level rose by about 2 millimeters per year, while
averaging about 1.5 millimeters per year in the second half even
though there was far more green house gas emissions is the second
half of the century.
http://www.agu.org/pubs/crossref/2007/2006GL028492.shtml
Now this is just the opposite of what has been predicted if warming
is engendered by green house gases rather than solar cycle
activity. Sea level change should respond more readily to
greenhouse gas emissions cuz the polar caps will melt more as a
result of the greenhouse gases carrying the heat to the poles via
convection as opposed to solar radiation cuz it's less direct on
the poles. But during the last half of the 20th century when there
was a big jump in greenhouse gases, there was less sea level
rise(caps melting) compared to the first half when thee was far
less green house gas production.
Rick,
I don't think anyone expects a clear 1:1 correlation between global
warming and sea levels. Remember that warmer temperatures also
increase evaporation. Additionally, to the extent that melting ice
caps decrease water salinity at the poles, this also increases
evaporation. I don't know the net effect of these various opposing
forces, but I doubt this is the "opposite" of our earlier
predictions, and even if it proves that earlier models were
incorrect, that doesn't mean much.
Mr. Will: you need to look up the term "Cassandra." You just
characterized those who recognize the reality of global warming as
accurate prophets, ignored in their own time.
Mr. Goldberg: North Korea had advanced its nuclear program from
posessing raw uranium ore to having a near-functional warhead,
without harming a single American. During that period, our economy
has grown quite a bit. Ergo, we have nothing to worry about if
their nuclear program continues.
I'm all for efficiencies and technological improvements, but
that doesn't get us anywhere near a reduction in actual
temperature, or even slow down the rate of increase much. People
are talking about the impact to human societies over a century in
the future, which is absurd because you have no idea what human
society will look like in a hundred years.
I am on board with any policy any environmentalist wants to propose
that won't hurt growth. That is my concession to the idea that 'we
should be doing something'. Can I get agreement from that camp that
growth of economies is the greatest engine of improvement to the
human condition ever to exist, and that they won't hurt billions of
people by advocating policies that are harmful to that engine for
no obvious gain?
I think pro-environmentalist are doing themselves an injustice
by attaching their anti-pollution stance to global warming. This
gives the pro-pollution crowd ample space to argue against it since
it's really difficult to prove, being that the planet has a history
of its own climate swings which the environmentalist do not like to
address.
It seems to me, if the pro-environmental crowd stuck with the
empirical science and made the case that pollution is bad for
people, (opposed to the planet), and we should limit pollution
because we deserve cleaner, healther air, they would advance their
case.
Many Republicans are jumping on the "you can't smoke because it
pollutes your lungs, and everyone's lungs around you". The
anti-pollution crowd could exploit that and gain extra support from
the global warming skeptics. Smoking is a form of pollution so is
car exhaust.
I think the evironmentalist would get more support and make better
gains if they widely framed the issue as opposed to making it a
global warming issue.

I am sticking close to stock on this one.
Maybe when I find a b-body 1970 or older I might do something like
that. Lots of cool new active suspension stuff for them too.

Also, don't forget that when floating ice melts the water level
decreases.

Will I look like a rube if I ask whether you are joking?
Will I look like a rube if I ask whether you are

Not sure what the proper, polite, term would be if you are simply
unaware of this basic scientific fact.
It can be obesrved easily by noticing that solid water (ice) floats
in the same water it was made from. That whole density thing. If
you freeze a volume of water, it takes up more room than when it
was liquid.
A more obvious example is placing ice in a container and then
filling the container with liquid water, marking the water level
and watching that level drop as the ice melts.
It does not matter if it is a floating ice cube or a floating ice
cap. When the ice melts it takes up less space than when it was
solid.
It does not matter if it is a floating ice cube or a
floating ice cap. When the ice melts it takes up less space than
when it was solid.
That is true. But note that the ice makes up for this higher volume
by sticking up out of the water.
When something floats in water, the volume of water that it
displaces has a weight equal to its own weight. Since the solid
water of floating ice weighs exactly as much as itself melted, ice
as it melts does not raise the water level at all.
In fact, in real life if the ice is less saline than the sea, the
melting ice will slightly raise the sea level because it
had been displacing less volume of the denser salt water that the
volume the fresh ice has once it melts.
Let's try this experiment, Fill your ice cube tray with water,
when the water freezes did the volume of water shrink, stay the
same, or get bigger? Of course don't expect big gains or
losses.
""But note that the ice makes up for this higher volume by sticking
up out of the water.""
If that statment is true then the ice cube will be bigger than the
volume of water. Right?
Or fill a glass with ice, then with water to the top, and observe
the water level as the ice melts.
Sorry Mike P I meant to include the above line too. It should
have been being that my comment was more directed to water
level.
""It does not matter if it is a floating ice cube or a floating ice
cap. When the ice melts it takes up less space than when it was
solid.
That is true. But note that the ice makes up for this higher volume
by sticking up out of the water"""
If that statment is true then the ice cube will be bigger than the
volume of water. Right?
Okay, now I know you all are pulling my leg. "Ha ha," you all are saying. "Look at the rube who actually thinks we don't know that melting ice has no effect on the level of water it's floating in. What a rube."
If that statment is true then the ice cube will be bigger
than the volume of water. Right?
Yes, it is bigger. It is bigger by the volume sticking out of the
water, since the part in the water displaces exactly the whole
cube's weight of water.
Or fill a glass with ice, then with water to the top, and
observe the water level as the ice melts.
If the ice is supported by the bottom of the glass -- thus
supporting a volume of ice above the water so that the volume of
ice in the water is smaller than that of the water displaced by the
weight of the ice -- then the glass will overflow as the ice
melts.
If, on the other hand, the ice is floating in the glass --
supported entirely by the water -- the level will remain at the top
of the glass as and until the ice melts.
MikeP and TrickyVic, you've got to consider the salinity of the
water compared to the salinity of the ice in order to fully answer
the question. They aren't equal and it turns out to have a small
effect on whether sea levels rise or fall, comparable in size to
the thermal expansion of liquid water.
From Sea Level, Ice and Greenhouses FAQ, at
http://www.radix.net/~bobg/faqs/sea.level.faq.html
"Sea ice is much fresher than sea water (5 parts per thousand
instead of about 35). When the ice melts (pretend for the moment
that it does so instantly and retains its shape), the resultant
melt water is still slightly less dense than the original sea
water. So the meltwater still 'stands' a little higher than the
local sea level. The amount of extra height
depends on the salinity difference between ice and ocean, and
corresponds to about 2% of the thickness of the original ice floe.
For 30 million square kilometers of ice (global maximum extent) and
average thickness of 2 meters (the Arctic ice is about 3 meters,
the Antarctic is about 1), the corresponding change in global sea
level would be 2 (meters) * 0.02 (salinity effect) * 0.10 (fraction
of ocean covered by ice), or 4 mm. Not a large figure, but not zero
either."
and made the case that pollution is bad for
people
Except that gases like carbon dioxide aren't normally considered
pollution. Most folks already accept that pollution is bad for
people. The case to be made is that excess levels of a gas that is
otherwise harmless should be considered pollution.
Not getting that not-all-that-subtle point, or pretending not to
get it, is what made the Competitive Enterprise Institute's "Carbon
Dioxide is Life" ads so embarassing and counterproductive for more
legitimate global warming skeptics.
you've got to consider the salinity of the water compared to
the salinity of the ice in order to fully answer the
question.
Yes. I made that point in my comment of 11:58am.
"...For 30 million square kilometers of ice (global maximum
extent)..."
Why "global maximum extent"? It should be average extent. When the
average freezes to the maximum, it lowers the sea level via the
same effect.
Aack. Missed that point, sorry for the redundancy.
The 'global maximum extent' was within a quote, and I'm not the
author, but I think he picked that figure to maximize the total
magnitude of the rise from a melting ice cap, in order to show how
very small the effect is. But yeah, when comparing average sea
levels you should use the average amount of ice coverage.
What will be so horrible about a 2-3 degree C rise in temperature
by 2100? Seriously. The sea level rise they mention in the FAQ I
cited above is quite small, on the order of 2m, I think. Rough for
the Maldives, some Pacific atolls and maybe the Netherlands, but
who else? Won't a 2-3 degree rise help increase growing seasons in
much of the world? The weather will worsen that much more with a
2-3 degree rise? Does that mean the weather was that much more
equitable 50-75 years ago?
I'm genuinely confused as to why AGW is supposed to be a total
catastrophe, and the IPCC report is not helping my confusion.
Can I get agreement from that camp that growth of economies
is the greatest engine of improvement to the human condition ever
to exist, and that they won't hurt billions of people by advocating
policies that are harmful to that engine for no obvious
gain?
No, no you can't.
The sea level rise they mention in the FAQ I cited above is
quite small, on the order of 2m, I think.
The sea wasn't that much higher during recent warm periods, so why
should it be that much higher if it gets warm again?
It would raise the price of energy and subsequently other
goods that take energy to produce, but income net would increase as
well, probably offsetting each other.
I'm not sure how raising taxes and input costs via a carbon tax
will raise net income, seeing as higher input and deadweight costs
usually lowers net income.
Gray Ghost,
best estimates (BE) from the IPCC are scenario dependent.
The Scenario we seem to be on (A1b) suggests a BE of 2.8 degrees C
by 2100. This means a minimal reduction in CO2. This is still an
additional four times the difference in temperature we have already
seen since preindustrial times.
The B1 scenario, a 'reasonable growth scenario', gets a BE of 1.8
degrees C by 2100. This means we reduce CO2 output by some 80% by
2050. Gristmill comments on how to make this possible:
http://gristmill.grist.org/story/2007/2/16/104655/313
In both those cases, after 2100 temperatures are expected to
continue to rise at around +0.5 degrees C before levelling
off.
Sea level rises are a bigger unknown at this point. The IPCC
removed estimates of sea level rise due to rapid glacial melting
due to incresed uncertanties in this department. So far we have
seen about 7 inches of mean global sea level rise. PaleoClimate
studies suggest that if temperatures stablizize at +3-4 degrees
celcius, then we may 'eventually' see about 3 more feet of sea
level increase. It should be stressed that there is greater
uncertainty in this area thanthere was in the last IPCC report.

Rick, nowhere in the astract you linked to does it claim, much less
show, that humans are not responsible for the current warming. It
only claims to show that sea level rise so far has been
unexceptional.
Sam-Hec,
The results of that research published in Geophysical Research
Letters most certainly is evidence that the warming is not the
result of human green house gas production. The prevailing paradigm
in global warming theory has been that sea level change will
respond more quickly and directly to green house gas emissions for
the reasons that I explained.
Based on this, the UN IPCC report, forecasts sea level increase
have an over 90% chance of being observable at 8 year intervals,
but here we have data that shows less sea level rise during the
last half of the 20th century (as opposed to the first half) just
when the theory predicts more of it. Cuz of this and other
research, the idea that anthropogenic warming is significant is in
deep trouble. The IPCC doing bad science in their meta study and
cherry picking the data won't save the paradigm. I hate it when
science is compromised for political reasons. But this is to be
expected in this case since some global warming scientist-activists
and activists have advocated lying about the global warming
question.
Chris S.:
I don't think anyone expects a clear 1:1 correlation between
global warming and sea levels.
The UN IPCC report, forecasts sea level increase have an over 90%
chance of being observable at 8 year intervals. Of course they
might well have done biased scientific reading to derive that
forcast.
University of Colorado climatologist Roger Pielke, Sr., thinks
that some of the claims made in the Policymakers Summary issued by
the Intergovernmental Panel on Climate Change earlier this month
are unsupported by the data.
"In even an overview of the section in the 2007 IPCC

Rick,
Nowhere in the abstract does it say that the current sea level rise
isn't anthropogenic in origin. Only that it is unexceptional wrt
past sea level rises.
Is well established that there was a notable increase in solar
activity the first half of the 20th century There should have been
sea level rise of some sort then without a preponderance of
greenhouse gasses. Now there is a greater amount of greenhouse
gasses...but no relatively significant solar increases in
radiation.
"but here we have data that shows less sea level rise during
the last half of the 20th century (as opposed to the first
half)"
This statement of yours is somewhat at odds with what the abstract
actually says:
"The rate of sea level change was found to be larger in the
early part of last century (2.03 ± 0.35 mm/yr 1904-1953), in
comparison with the latter part (1.45 ± 0.34 mm/yr 1954-2003). The
highest decadal rate of rise occurred in the decade centred on 1980
(5.31 mm/yr) with the lowest rate of rise occurring in the decade
centred on 1964 (−1.49 mm/yr). Over the entire century the mean
rate of change was 1.74 ± 0.16 mm/yr."
It never says that the later half of the 20th century sea level
rise wasn't anthropogenic. All that can be infered based on what we
see from the abstract is (probably) that the total warming
influences on the seas' level was overall less during the second
half than during the first half; it should be noted that the
strongest sea level rise occurance centered on 1980, during the
second half. (It should also be noted that the second half was less
steady in how much the sea level rose.)
This really just means that there was a stronger warming trend
during the first half...nothing is mentioned as to why there was a
stronger warming trend. There are a variety of forces at work, some
wax some wane, some stay put; Man's influence is only one of those
forces, and during the second half of 20th century, our CO2 signal
simply wasn't stronger than the preceding half's more natural
warming signal. That doesn't that future CO2 signal isn't a
problem
You speculate about what the IPCC says and/or has a paradigm about,
but you don't show anything. As of now, however, sea level
estimates by the IPCC are up in the air, as they work to refigure
rapid glacial melt models. Speculations about 20+feet of sea level
rise anytime soon is just that, speculation by politicians and
pundits; it is not the 'paradigm' or working climatologists.

Sam:
Nowhere in the abstract does it say that the current sea level
rise isn't anthropogenic in origin. Only that it is unexceptional
wrt past sea level rises.
The salient point is that it shows a leveling off of sea level rise
when the theory predicts that there should be an
acceleration.
Is well established that there was a notable increase in solar
activity the first half of the 20th century.
Could you please supply a link giving evidence that solar activity
was greater in the 1st half of the 20th century vs the 2bd half?
But what ever, Sea level rise in response to solar engendered
warming is not supposed to be as time responsive as green house gas
engendered warming cuz the solar radiation warming is a "direct
hit" phenomena and it falls less directly on the poles. Green house
gases would engender warming via a different dynamic.
This statement of yours is somewhat at odds with what the
abstract actually says:
Breaking down my observation of two half century time frames into
smaller time frames does not negate the observations.
Given the lack of intellectual honesty displayed in the IPCC
report, It should not be surprising that they are de-stressing sea
level increase since it is not corroborating anthropogenic
warming.
Thank you for the link. I already have the IPCC report (at least
what they've released so far.) I hear that they're going to make
sure that the rest of what they release supports their conclusion
before they release it. That doesn't sound good if your into honest
inquiry.

"The salient point is that it shows a leveling off of sea

We arenot dicsussing 'theory' we are discussing observations.
Following the graph on page 6 of the IPCC report I linked to, the
first of the of the 20th shows about 50mm of sea level rise,
followed by the second half wiht about 100mm of sea level changes.
Based off that, the expectation of acceleration is
confirming.
All aspects of the IPCC paper must be reviewed and unanimously
agreed upon by all participating scientists and nations. In short,
its one huge Peer Review. Contoversial or significantly uncertain
aspects of climatology will by it's very nature not get into the
Report.
The AGU abstract you linked to likely did not receive nearly as
much review. Why did it's results not get included in the final
Report? Perhaps it was in error and the error was caught, and the
paper dropped accordingly; or maybe it was late in the game (other
worthy things didn't get included...it takes time for all these
reviews to happen); m,aybe it was too controversial.
"Could you please supply a link giving evidence that solar
activity was greater in the 1st half of the 20th century vs the 2bd
half?"
Semantically, I am looking at the change in solar energy during the
first half, as technically there was less overall solar energy on
average during hte first half. It is the changes that are
important:

"Given the lack of intellectual honesty displayed in the IPCC

I reemphasise that your AGU paper is just one paper, from one guy,
who likely received only a small Peer Review (which sometimes
aren't very good.). Apparantly the IPCC rejected it for errors,
controversy or uncertainty (or tardiness); that one paper while it
seems to contradict the IPCC, it does not by itself disprove past
observations as stated in the IPCC report. Whom are destressing
'future' sea level changes due to increased uncertainty in glacial
melting...not past ovservations.

rick,
any idea where I can find those booknotes episodes on the Web?
BookNotes website itself seems to be down.
I amthinking R. Pielke Sr. is making a number of errors in his
criticsms, some of which he gets challenged on in the comments
section...but it is late for me now...I go sleep.
Sam,
I'vr never been to the BN site. I catch it sometimes on Cspan2. I
really dig it.
I'll go back to the Pielk thread. Forgive me if I don't trust your
assessment. You seem a tad biased. :)
I don't have cable or sattelite or such, so I either have to
rent, borrow a recording, or find it on the internets.
WRT Pielke Sr.
the first item cuahg tmy Attentions:
"1. The IPCC SPM writes on page 7
"… snow cover have declined on average in both hemispheres."
The Rutgers University Global Snow Lab Northern Hemisphere Snow
Cover Anomalies plot through January 2007, however, shows that the
areal coverage in the Northern Hemisphere has actually slightly
increased since the later 1980s!
Since the inference from the IPCC SPM is that global warming is the
reason for these changes, this is at best a clear example of
selecting a time period that conforms to their conclusion rather
than presenting an up-to-date description of snow cover
trends."
However, the sentence from the IPCC actually says:
" Mountain glaciers and snow cover have declined on average in
both hemispheres."
R. Pielke ommited the mention of Mountain Glaciers. Then he shows a
graph of just snow cover patterns...and no mention of the glaciers
which were a part of the IPCC sentence. Additionally the graph
linked to shows not 'average snow cover', but 'snow cover
anomalies'. These are not quite the same things; and even then,
staring at the whole graph lead sme to think that there is an
overall declining trend in snow cover...even if we start the the
80's as Pielke suggests; if we start from 1988, then it
looks like there is an increase in cover...but that is classic
cherry picking.
p.s.
if you look on page six of the IPCC report you will see a very
similar graph which goes back to the 1920s. Overall it looks like
less snow cover, no mentoiomn of if it includes glacier cover as
well.
I have no idea what Pielke means by 'areal' perhaps it deservs a
{sic] next to it.
Perhaps glacier data are included in his graph of snow cover patterns even though he does not mention them. I'm going to see if I can get Prof. Pielke to come on this thread and explain. Perhaps I have do some standing to do so since I'm a CU alum and a Colorado taxpayer. ;)
...Shoulda been: Perhaps I do have some standing to do so since I'm a CU alum and a Colorado taxpayer. ;)
a likely place to try is at the same article he posted in the comments section...assuming it is still possible
Sam,
Your idea to ask him in his comments section is good too. Still,
I'm gonna call him and ssk if he'll come on the H&R
thread(s).
I think he'd be happier joining the discussion about his article...not George Will's...not that they are much at odds or anything.
