Congressional Testimony: A Surprising Consensus On Climate 370

Lasrick writes: Many legislators regularly deny that there is a scientific consensus, or even broad scientific support, for government action to address climate change. Researchers recently assessed the content of congressional testimony related to either global warming or climate change from 1969 to 2007. For each piece of testimony, they recorded several characteristics about how the testimony discussed climate. For instance, noting whether the testimony indicated that global warming or climate change was happening and whether any climate change was attributable (in part) to anthropogenic sources. The results: Testimony to Congress—even under Republican reign—reflects the scientific consensus that humans are changing our planet's climate.

          "Open and Reproducible" is a nice phrase. It sounds so sensible, how could anyone be against it.? If you read the articles linked to, you find the bill requires EPA to jump through hoops and obtain the raw data that went into third-party peer-reviewed studies. Often times, that raw data contains names and facts about individuals and releasing it would have privacy concerns.

          This bill is about adding extra, unnecessary work in an attempt to slow down and hobble the EPA, not about "open science".

        You are missing what parts scientists are well agreed upon:
        1.The instrumental record, which spans about 100 years, shows a clear warming trend.
        2. CO2 is a greenhouse gas and increasing it's concentration will increase heat storage.
        3. CO2 concentrations as observed for about the last 60ish years have been increasing.
        4. Humans have been steadily contributing CO2 to the atmosphere for about the last 100 years.
        5. The above points clearly are strong evidence that the recent warming has been influenced by human behaviour.

        That about encompasses the consensus. 90% of everything that everyone is talking about though does NOT have a broad consensus and is still being actively studied, things like:
        1.What quantitative relationship do our CO2 emissions have to future temperature change?
        2. What cost is there to us from future temperature change.
        3. What cost is there to us for reducing our CO2 emissions by a set factor.

        Climate models are one of the key parts to answering these questions, and they are getting better at helping us study our theories on how climate works. Regrettably, the reality is that climate models still do NOT accurately predict or model global Top Of Atmosphere energy imbalance. One of the key tuning processes in model development is still adjusting loosely bound or poorly understood parameters, like clouds, to force a reasonable behaviour of global TOA energy. I hate to have to point it out, but long term predictions of climate, are pretty much entirely driven by TOA energy imbalance as it IS the entirety of the greenhouse effect.

              I'm glad we agree. The IPCC represents the best scientific knowledge of our time, but there are uncertainties. That's why the climate sensitivity is given by the IPCC as a range rather than a specific value. "global mean equilibrium warming for doubling CO2 (to a concentration of 560 ppmv), or equilibrium climate sensitivity, very likely is greater than 1.5 C (2.7 F) and likely to lie in the range 2 to 4.5 C (4 to 8.1 F), with a most likely value of about 3 C (5 F)."

    The whole reason science in general works is because there are no leaders. Consensus means nothing. The only problem is that science can never discover the "Truth" (tm). The best it can do is come up with a model that has yet to be disproven. If there is no way to disprove it is faith not science.

    • Models aren't "proven or disproven", they're not found to be 100% correct or 0% correct, they're approximations. They can of course be tested by making predictions - which will also not be 100% or 0% correct. The only relevant question is, are the predictions accurate enough to be useful?

      Your model of how science works appears to be a poor approximation, as science has indeed turned out to be useful.

        An important part of creating a model is listing your assumptions. Hence the Physics jokes about spherical cows. An important part of science is figuring out of those assumptions are general.

        So Newton's model of gravity was incorret because we have proved it doesn't work in certain circumstances. So far General Relativity (unless I'm mistaken) is the best model we have so far because we have not found evidence it's wrong yet.

        This doesn't mean Newton's model isn't useful as long as you are aware of the assumptions and their limitations.

          This is not a useful assertion, as you could say that about everything outside of pure mathematics. Newton's model of gravity turns out to be still quite useful, as it is mostly correct - good enough for most terrestrial uses. Likewise, we already know General Relativity isn't perfect either, but it's a better approximation, sufficient for most non-terrestrial uses too.

    2) Climate change exists, but it isn't happening now.
    3) The climate is changing, but it isn't being caused by humans
    4) The climate is being changed by humans, but we can't (or shouldn't) do anything about it.

    Apparently, we've just passed step 3. With step 4, expect a deluge of reports about how we shouldn't try messing with the climate because we just don't understand it well enough and probably will make things worse, or because any benefits from changes WE make will be lost because THEY following suit (for various values of "they", but most likely China or India) or because the potential loss of revenue to a few entitled mega-corporations is far too important to risk by imposing ecologically-responsible regulations. In short, the arguments will be that since we can't make everything 100% better, why should we make any attempt at all?

    Climate change deniers will continue to be wrong until we reach step 5, when they will suddenly - and to all our misfortune - be right. We can only hope that the ecological mess they cause in the name of short-term profits won't be so catastrophic for the rest of us.
