April 2016 was the fourth warmest month in the satellite temperature record, but only the second warmest April (just behind April 1998 at +0.73 C, although the difference is within the error range of +/- 0.1 C), when compared to seasonal norms, according to Dr. John Christy, director of the Earth System Science Center at The University of Alabama in Huntsville in a press release.

April and March 2016 anomalies were similar, with some hint that the El Niño Pacific Ocean warming event's warming of the atmosphere might have passed its peak. The ten warmest months in the satellite record (compared to seasonal norms) are now all from either the 1998 El Niño or the ongoing 2016 El Niño.

The recent uptick in warming has been sufficient to raise the global climate trend from +0.11 to +0.12 C per decade.

      Speaking of which, what happened to Tony? I kind of miss the guy.

      /masochist

      1. Last I heard he was allowing some young male Syrian refugees move into his guest villa.

        1. I thought he stated that though he cares deeply about the plight of poor brown people he doesn’t want to actually see or interact with them, much less have any residing in his gated community.

          Progress?

        1. Joe, Jack, Craig, Tulpa, Epi’s mom, it’s becoming difficult to sort all this out.

  7. It still boggles my mind that people think they can measure *global* temperature, much less to +/- 0.1 C.

    1. It’s actually a lot of work to cherry-pick the individual data points that will average out to a number that guarantees a continuation of the grant money you use to pay your bills.

      1. Folks: All temperature data must be adjusted – changes in thermometers, siting, urbanization, etc. The satellite data have had to be adjusted to take into account differences in measuring instruments, differences in orbits, etc. There are two groups who independently make their adjustments to the satellite data – UAH and RSS – yet their trends are close matches. In addition, the satellite data matches nicely with weather balloon data. I have been reporting the work of the folks at UAH (who are quite skeptical of the more catastrophic predictions of man-made climate change) for nearly 25 years and so I tend to trust what they report. Your views may differ.

        1. Where’s the raw, unadjusted CRU temperature data?

          Oh right, it doesn’t exist anymore, because the top criminals behind this scam destroyed it to cover their lying, dirty little tracks, with the ludicrous claim that they had to because they “ran out of storage space”.

        2. Ron, glad to see you’re ready to provide testimony in the US Virgin Islands…

          Your balanced and fair approach will likely not save you from the inquisition.

        3. All temperature data must be adjusted

          Indeed. And, the raw data and all adjustment methodologies should be publicly available.

          There’s just way too many questions about the adjustments, especially the historical ones which always seem to move the historical baseline colder.

        4. Last I heard, NOAA was getting rid of rural measurement stations and averaging with metro area’s but I’m entirely too busy today to check if that’s right or not.

        5. I would buy this bullshit Ron if it wasn’t obvious that all data was adjusted upwards, regardless of what the number was, before they then made away with the base data so those that were suspicious and asked to be able to verify their methodology couldn’t then call them out on this blatant manipulation to push a narrative..

          As someone that values the scientific process and method, I know and would expect that something like this would discredit everything these idiots say. Instead, they cry consensus, call others heretics, and demand an inquisition and public executions. Feels too much like religion and totally not like science to me…

        6. Folks: All temperature data must be adjusted – changes in thermometers, siting, urbanization, etc.

          yup- and them “scientists” are so awesomely smart that they can do it so perfectly that their magin of error is 0.1C

    2. It boggles my mind that people think that a change of between 1-2? C to an average temperature over the past century indicates impeding disaster, when the temperature can shift by ten times that amount in one day. Have these people never heard of the statistical term “variance”?

  8. Still looks like a really strong El Nino, to me.

    1. ^ This

  9. Meanwhile, I’m still having to wear a sweatshirt most of the time when I go outside, which is pretty rare halfway into Spring.

  10. Interesting new study about the erosion of the coral reef off Florida due to ocean acidification. Recent studies have shown unprecedented destruction of Australia’s Great Barrier Reef due to warming ocean temperatures, and now a new study says something similar may be under way in Florida.

    One of the author’s, Chris Langdon, said that scientists thought it might only start in 2050, but it appears to already have started. He said “this is what I would call a leading indicator; it’s telling us about something happening early on before it’s a crisis. By the time you observe the corals actually crumbling, disappearing, things have pretty much gone to hell.”

    It’s estimated that reef generates $7.6 B for the Florida economy.

    1. Set a fart on fire, and look who shows up.

      1. Like a moth drawn to a methane flame…

    2. Recent studies have shown unprecedented destruction of Australia’s Great Barrier Reef due to warming ocean temperatures

      Or, one might say, “recent studies have distracted attention from the actual causes of the destruction of the Great Barrier Reef by screaming about global warming to the exclusion of all else”

      HTML is fun!

    3. Interesting new study about the erosion of the coral reef off Florida due to ocean acidification.

      Interesting article about the discovery of a huge coral reef in Brazil.

      1. But…but… global warming is always bad! It’s man-made, so it must be evil! Warm periods in history never correspond favorably to periods of human proliferation and achievement!

        1. Man, what a fucking stretch you have to make to blame warming on acidification. What? CO2 abundance is causing a reaction in water that suddenly produces sulfuric acid? I would then expect that we can find plenty of evidence that when the planet was much younger and hotter, with CO2 concentrations that make what we see today look like child’s play, that the oceans would have been deadly acid baths…

          Belief in this warming shit isn’t science: it is quasi-religious and downright cultish behavior.

      2. Thanks for that, RC! Note the reef there is thousands of years old, not new. Since it was just discovered, there is no way to tell if it is eroding.

        http://advances.sciencemag.org…..4/e1501252

        Patricia Yager, one of the leads of the team who discovered it, is warning that it is under threat from warming temperatures AND oil exploration. Her quote, from your article:

        “From ocean acidification and ocean warming to plans for offshore oil exploration right on top of these new discoveries, the whole system is at risk from human impacts.”

        I can always count on you, RC, to cite sources that say the opposite of what you think it says. Keep em’ coming!

        1. I said the link shows a newly discovered reef.

          How is that the opposite of what the link shows?

          Although, I do find it odd that these reefs have been around in periods when the CO2 content of the atmosphere is higher than it is now, if high CO2 kills reefs.

          1. More links please!

            1. Typical proggy, wanting me to enact his labor.

              1. Oh, hell, why not:

                Corals appeared about 500 million years ago or more, at the same time that many other kinds of marine organisms were evolving. Thirty million years later, reef-like structures dominated by coralline skeletons were widespread.

                http://nature.ca/notebooks/english/coral.htm

                So, you ask, what was the CO2 level 500 million years ago compared to today? Why, much higher, as it turns out:

                http://www.biocab.org/Carbon_D…..scale.html

                1. And thus R C illustrates why the CO2 levels are always compared to just a few hundred thousand years ago.

            2. I do find it odd that these reefs have been around in periods when the CO2 content of the atmosphere is higher than it is now, if high CO2 kills reefs.

              RC raises a pertinent point here regarding, you know, an empirical observation that problematizes the idea that CO2 kills reefs. But you’ve never been one to actually address counter-arguments.

              As an environmentalist, I wonder – have you ever considered that something other than CO2 is damaging coral reefs? Or do environmentalists only have one answer to choose from?

        2. So

          Patricia Yager, one of the leads of the team who discovered it, is warning that it is under threat from warming temperatures AND oil exploration

          Even though

          Since it was just discovered, there is no way to tell if it is eroding.

          Is that about right?

          1. You got it.

            1. Went right over your head, didn’t it?

              Allow me to spell it out:

              By what scientific principle does Yager make this statement based on observed phenomena?

    4. How’re those nino regions looking? Seems like a nice la nina is forming. Oh dear, what will that do to the trend?

      1. Other than the next LaNina will be warmer than the last, nothing.

  11. So the El Nino is ending. Damn, those things are really good to Texas. It will be sad to see the rain go.

    1. Well unless you live in Houston like me, and there were floods everywhere

  12. Now that is an actual hot month — 0.7 degrees above average.
    All of the rest were within +/- 0.5 degrees, the year-to-year normal fluctuation.
    None of the previous data show an actual discernible trend — it’s random noise and confirmation bias and tea-leaf reading all the way down.

    1. ^^^THIS^^^

      It’s people with a predefined agenda and conclusion trying to make reality confirm…

  13. I’m so Trumped/Hillary’d out, I can’t even summon the energy to tease Ron. Is it too early to start drinking?

    1. Is it too early to start drinking?

      It’s five o’clock somewhere!

  14. I’m curious – is an El Nino weather, or climate?

    1. Depends on next year’s temperatures.

    2. Well the models can’t replicate them, so I’d say climate.
