Global Temperature Trend Update - June 2013

ThermometerCredit: Meryl:dreamstimeEvery month University of Alabama in Huntsville climatologists John Christy and Roy Spencer report the latest global temperature trends from satellite data. Below are the newest data updated through June 2013:

Global climate trend since Nov. 16, 1978: +0.14 C per decade

June temperatures (preliminary)

Global composite temp.: +0.30 C (about 0.54 degrees Fahrenheit) above 30-year average for June.

Northern Hemisphere: +0.34 C (about 0.61 degrees Fahrenheit) above 30-year average for June.

Southern Hemisphere: +0.26 C (about 0.47 degrees Fahrenheit) above 30-year average for June.

Tropics: +0.22 C (about 0.40 degrees Fahrenheit) above 30-year average for June.

(All temperature anomalies are based on a 30-year average (1981-2010) for the month reported.)

UAH climatologist John Christy notes that they are in the process of incorporating data from new satellites so that the newly processed satellite data varies slightly from their earlier data series, e.g., by as much as 0.04 degrees Celsius.

    I have to admit, it is somewhat amazing that in 1978 we apparently had satellites that could take temperature readings on the planet's surface from orbit.

  • JW||

    Yes, but they had to take the reading in the planet's anus.

    Detroit?

  • SugarFree||

    I prefer to think of Detroit as "America's Baldspot."

  • some guy||

    Detroit is a former glory city that is now broken and dysfunctional in its old age. We have made numerous attempts to return our Detroit to its former productive majesty, but the erosions of time cannot be reversed by these quick-fix pills. Clearly Detroit is America's flaccid impotence.

  • SugarFree||

    But Florida is America's Wang.

  • ||

    Which makes Georgia and Alabama America's nuts. That puts the asshole somewhere in Mississippi.

    Malaise powered devices gave us an unrepeatable tech jump.

    WHAT? Is there no part of climate science where they haven't pull the old bait and switch on me?

    OH MY GOD YOU GUYS it is totally legit because it is on CNN.com! Errr...

  • Wind Rider||

    Huntsville. The have engineers there. People drive from all over the state just to visit and feel smarter simply being there.

  • Matrix||

    I live there. Nice area. Much different from the rest of Alabama.

  • The Late P Brooks||

    The temperature goes up; the temperature goes down.
    You can't explain that.

  • sarcasmic||

    Temperature goes up and it's evidence of climate change. Temperature goes down and it's just weather. See?

  • kinnath||

    Last year's massive drought (worst drought in 300 years) -- that's climate change.

    This year's extreme rainfall and flooding -- that's climate change.

  • Cytotoxic||

    Last year's massive drought (worst drought in 300 years)

    Wrong. The late '80s drought was worse.

  • Raston Bot||

    I rate Ron a 7.

  • robc||

    I rate him a -2. Too many articles on Pigovian tax proposals.

  • Raston Bot||

    I was going purely on looks. For quantifying externalities into tax revenue Ron's rating drops precipitously.

    Have I missed any big brew announcements? I'm 50 bottles short for this weekend's bottling of 10g of IPA (dry-hopped with Summit™ and Cascade leaf) and 5g of wheat/pilsen that's been dry-hopped with Citra® leaf. Must transition to keg soon!

  • ||

    IPA? Ughh!

    *spits on floor*

    What are you, one of them cosmotarians?

  • Raston Bot||

    Is the new revolution over IPA colonialism now?

  • robc||

    The English whinging (spelling intentional) over British brewers now using west coast hops and making American-style IPAs if awesome.

    My favorite beer taunt though is the brewpub in Vienna named 1516, which was the year the Reinheitsgebot was created. Its an american-style brewpub with lots of stuff added to the beer that doesnt fit the purity law.

  • Raston Bot||

    Their palates are undergoing the lupulin shift.

    Whether their growers have the climate and soil to mirror our high AA and oils is another question.

  • robc||

    Whether their growers have the climate and soil to mirror our high AA and oils is another question.

    Its not even being asked. The Brits barely grow hops anymore. They are fine importing them from the PNW.

  • Floridian||

    I will second the IPA hate. It is far too bitter for my taste.

  • robc||

    Bitter is for sophisticated palates.

  • kinnath||

    My beer and metheglin were well received by several serious brewers at a summer party. They said that it was good beer.

    But I can't drink it. I drink glass of the pale ale, and all I can taste is bitter for about 15 or 20 minutes afterwards. I've been told that supposed to be a good thing, but I can't deal with it.

  • Raston Bot||

    Isn't the bitterness derived from the boiled alpha acids converted into iso-alpha acids? Then cut down on the bitterness by decreasing the amount of AA in the boil. If you dry hop, then hop oils are extracted without the increased bitterness.

  • kinnath||

    It's my palate. I enjoy big, heavy, tannic red wines from Italy (Borolo anyone?), but anything with hops turns me off.

    Now the metheglin, which has 8 or 9 other herbs and spices in it besides hops, I sort of like. So it's not that hops is a total killer for me. But I can only drink beer if I am having it with a meal.

  • Raston Bot||

    Curious, was your astringent-centric palate acquired?

  • kinnath||

    Probably.

    I didn't drink much of anything until I was introduced to mead and melomel about 10 years ago. Then I started making meads (semi-sweet to start with and drier as time went on).

    I also started taking wine appreciation classes so I would have a baseline for evaluating the meads I was making. At some point I discovered that I really really like big earthy red wines (mostly European). Now, I am not impressed with the oak-bombs made on the west coast or Australia, but I do have some nice Napa and Aussie wines down in the cellar.

    Yet I still have not developed any appreciation for hops. I can drink a few beers at a social gathering as long as food is being served, but I will go for wine instead if is available.

  • Raston Bot||

    So an astringent, non-bitter, non-hoppy beer. A black, sweet stout might be to your liking. They're typically brewed with milk sugar (lactose) which has something like 1/10th the sweetness of sucrose. Bell's Double Cream perhaps though I can't recall if there's enough black malt for the astringency to shine through.

  • kinnath||

    I will keep that in mind.

  • kinnath||

    I don't drink coffee either -- I hate the bitterness.

    Someone badgered me into tasting a coffee-stout at a party last winter. What a hideous concoction that was ;-)

  • datcv||

    Smooth roasted malts bitter hops

  • datcv||

    Damnit reason.

    Smooth roasted malts GREATER THAN SYMBOL bitter hops

  • ||

    I really tried. I thought it might grow on me. Nope. I don't get it. Who wants to drink bitter beer?

  • robc||

    Who wants to drink bitter beer?

    Right here.

    I also want to drink malty beer. And wheaty beer. And sour beer. And earthy beer. And sometimes, fruity beer.

    Not so much for roasty or smokey beers. But I dont hate stouts or rauchbiers, I appreciate them for what they are and just dont drink them.

  • Floridian||

    Orlando brewery has a porter that is like coffee and bacon in a bottle. Delicious. They also have a blonde ale that is really refreshing on a hot day. I too have tried IPAs and just can't get into it. If someone home brewed one and swore by it I would give it a try but other than that, I am done with them.

    I'm with you there, I don't like smoky beers. Recently a store opened in my neighborhood that has all sorts of microbrews, IPAs, pale ales, etc. While Czech pilseners are awesome, that's basically that is served or sold here, one does long for something different.

  • datcv||

    Malty Beer, Sour Beer, Earthy Beer, Salty Beer (

  • datcv||

    I give up. Reason trolls are eating my comments. I didn't even use any verboten symbols this time.

  • anon||

    I don't get it. Who wants to drink bitter beer?

    I'm pretty sure most of us are alcoholics here. You may want to retract your question.

  • ||

    Beer is for when you are hot and thirsty. Bourbon is for when you get serious.

  • robc||

    Ron,

    I would still like to see the baseline as a rolling 30 year average, instead of a 1981-2010 30 year average. Less arbitrary.

  • kinnath||

    I think it should be scaled to match human experience with the y-axis running from say -25C to +125C.

  • Floridian||

    Ron,

    What temperature is the earth suppose to be? Paleoclimatologists keep telling me the earth's temperature has varied widely throughout its history.

  • sarcasmic||

    Whatever they were before the Industrial Revolution, because that's when human kind really got to killing Mother Gaea.

  • kinnath||

    Does 1,000 C.E. work for you? How about 0 C.E.? Or maybe 1,000 B.C.E.?

  • ||

    Paleolithic Period or GTFO

  • ||

    Well if you start in 1981, then ignore the last 10 years because they aren't a long enough timeframe to produce any meaningful data, it turns out you wind up with just enough data to notice a catastrophic, precipitous warming trend. 10 years is too short, 50 years is too long, but 30 years is juuuuuust right.

  • ||

    I believe there has been no significant change since 98. That's 15 years. But that's just a blip, regardless. I'm sure the next few years will get us back on Al's hockey stick curve.

  • Auric Demonocles||

    Looking at the graph it seems pretty much oscillations around a mean from 79-98, then that huge El Nino spike, then after that oscillations around a new mean (slightly higher than the pre-El Nino mean). No warming trend, just a reset of the mean.

  • Spartacus||

    The graph really looks like two flat intervals (roughly pre-1995 and around 2002-present) connected by an actual rise in between. It would be interesting to look at trends over these periods separately.
