New NASA Data Casts Doubt On Global Warming Models

bonch writes "Satellite data from NASA covering 2000 through 2011 cast doubt on current computer models predicting global warming, according to a new study. The data shows that much less heat is retained by carbon dioxide in the earth's atmosphere than is assumed in current models. 'There is a huge discrepancy between the data and the forecasts that is especially big over the oceans,' said Dr. Roy Spencer, a co-author of the study and research scientist at the University of Alabama." Note: the press release about the study is somewhat less over the top.

    We should follow wherever the data leads. That's science. Up till now, the data has suggested that global warming is very real.

      That data indicates that Earth is warming up, for a particular period of time. It does not directly indicate that the world is going to continue warming up, nor does it by itself tell why it's warming up (which you need to know to answer the first question).

      Hence why you take the data and build a predictive model. Of course, if you have insufficient or incorrect data, then your model is also incorrect, and so are its predictions. Of course, there are varying degrees of "wrong" - it may be that a model based on this new data would simply show a lower rate of warming, for example; or it may be that it completely demolishes the warming positive feedback loop. We'll see.

      Either way, that's how science works. It starts with data, and a hypothesis based on that data; but you have to continue with predictions based on your hypothesis, and experimentally verify them. And, of course, you should always verify the data as well.

  2. Here's to hoping Climatologists are dead wrong. by NeutronCowboy · · Score: 4, Insightful

    I really wish the people at the Heartland Institute are right. I really do. I'd hate to witness major migrations because farming conditions dramatically change across the globe. But I also really, really wish they'd drop the sensational language (alarmist models, etc), because I'd able to actually take them seriously. Not to mention that I also would like to see them actually properly quote the papers they reference. For example, the abstract in this particular paper is actually far less strong than what the venerable James Taylor says.

    Abstract:
    "The sensitivity of the climate system to an imposed radiative imbalance remains
    the largest source of uncertainty in projections of future anthropogenic climate change.
    Here we present further evidence that this uncertainty from an observational perspective is
    largely due to the masking of the radiative feedback signal by internal radiative forcing,
    probably due to natural cloud variations. That these internal radiative forcings exist and
    likely corrupt feedback diagnosis is demonstrated with lag regression analysis of satellite
    and coupled climate model data, interpreted with a simple forcing-feedback model. While
    the satellite-based metrics for the period 2000–2010 depart substantially in the direction of
    lower climate sensitivity from those similarly computed from coupled climate models, we
    find that, with traditional methods, it is not possible to accurately quantify this discrepancy
    in terms of the feedbacks which determine climate sensitivity. It is concluded that
    atmospheric feedback diagnosis of the climate system remains an unsolved problem, due
    primarily to the inability to distinguish between radiative forcing and radiative feedback in
    satellite radiative budget observations. "

      The greatest change of farming conditions around the world today, is the absurd willingness of industrialized countries to burn huge quantities of food. 140mio tons of maize are burned as ethanol in the USA alone - that's one quarter of the world maize harvest or 5% of the world coarse grain harvest. In order to provide less than 5% of the world population with about 1% of their primary energy needs.

      Europe is burning similar amounts of "biofuels", so we're burning something on the order of 10% of the world's grain harvest - and people wonder why Somalians don't have enough money to buy food. More artificial demand through biofuels means higher prices, because when you burn food, food is getting scarce.

      Basic economics.

      We're killing people to save them from the "deadly effects" of global warming (and shove billions of dollars into farmers pockets who benefit a whole lot from the huge increase in food prices). And you'll wonder where the next Jihad came from ...

    Yup. The government can borrow at lower rates than the rest of us, and use the money to provide us with a safety net so that we can take risks in spending more, helping to break the self-sustaining cycle of a recession. Just look at how poorly austerity plans have worked out when used.

    I agree that alarmists need to put a lid on it. Running around like your hair is on fire certainly doesn't inspire confidence in the logic of anothers arguments, and it's the thoughtful objective response that intelligent people are more often swayed by. By the way, you should notice the source of the first link in this article is from the leading conservative think-tank opposing the existence of Global Warming. Not exactly the first place I would have gone to for an unbiased opinion.

    The wise person looks a scientific consensus (and yes, makes some accounting for political leanings in either direction.) One looks at many disciplines, meteorology and long term climatology, chemistry, oceanography, biology, ecology, geology. One investigates all the signs, looking for impacts in hydrology and everything from frequency of drought, flood, and changing global micro-climates to large scale animal migrations and the changing timing of spring and fall do the shorter, warmer, wetter winters. You can't argue the ice in the Arctic is vanishing. You can't argue that the chemistry of the ocean is changing (decreased salinity from fresh water melt and rising acid levels from carbonic acid due to rising CO2 levels.) Heat trapping and reflection is incredibly complex. A a single large volcanic eruption (like Mt. Pinatubo) can emit enough SO2 to completely skew the results for any specific decade. That's why you need to look at long term trends over decades and centuries to see where the planet is heading.

    I continue to hear critics of "global weather change" cherry pick items to rail against. I see nobody from that camp providing a cohesive response to tens of thousands of different phenomena all pointing in the same direction. There is sadly little informed debate to the contrary, more and more those arguing against the existence of something serious happening to our environment sound like relics from the flat earth society. I won't apologize for people's shoddy work on either side of the issue. When you deal with people there will always be clowns. I will say that folks with personal axes to grind on this topic simply can't address tens of thousands of intelligent, professional, scientists all over the world who've created a consistent, cohesive body of theory and information that concludes with near certainty that we are dangerously close to destroying our environment through the wanton burning of fossil fuels.

    The body of work has some holes in it. The debate is far from over, as this paper demonstrates.... But... The real problem is the proposed solutions. The proposals create a global framework that is so strict and so rigid that it requires the creation of a global government to enforce it.

No regional or national government is willing to place themselves under such a regime, and individual people are often horrified at the thought of having yet another government they can run afoul of.
