View Diary: New study: Amount of warming from increasing CO2 levels 'overestimated' (28 comments)

  •  I think this study is suspicious, especially since (5+ / 0-)

    it comes on the heels of the IEA report that we have five years before we encounter permanent damage to the environment.

    It smacks of studies funded by the Koch brothers to counter the overwhelming amount of information that we're seeing laid out by the international community of scientists.

    Even the first sentence of the blurb is a little suspect:

    Assessing impacts of future anthropogenic carbon emissions is currently impeded by uncertainties in our knowledge of equilibrium climate sensitivity to atmospheric carbon dioxide doubling.

    That sounds very much like the language that is being used by climate change deniers.

    Also, in the current edition of Science you find this:

    An international scientific assessment finds for the first time that human activity has indeed driven not just climate change but also increases in some extreme weather and climate events around the world in recent decades. And those and likely other weather extremes will worsen in coming decades as greenhouse gases mount, the report finds.

    Even that article contained this sentence:

    But uncertainties are rife in the still-emerging field of extreme events.

    I wonder if they are feeling the same type of pressure that the conservatives are applying to the the Discovery Channel?

    •  There are "uncertainties in our knowledge" is just (7+ / 0-)

      a plain statement of truth and I think it is a bit much to suggest that the study is suspicious. I am not a climate scientist but I know they are constantly trying to fine tune the climate models that have been developed, that's what they do. And with further information the models will continue to be refined, this study is just one step along the way.

      But yes, climate change deniers use the rubric of science to sow doubt and we do need to be on guard against that, but to preemptively question a study because the result goes against your thinking is not the way to do it.

      I am sure other climate scientists will be weighing in on this report in the upcoming days and weeks and I think it would be wise to wait and hear the various comments and criticisms before forming a judgment.

        I am seeing a lot of credible environmentalists countering their assumptions...I just read an article by Robert Kennedy, Jr. discussing the increased efforts that are being made by climate deniers (sponsored by the oil companies) to discredit environmentalists.  

    •  This is Science (2+ / 0-)

      It isn't sham or poorly done. It is scientific. No pressure there--if any, in the other direction.
