      Climate Change and Timescales (Part 1): Why "Global Wobbling" doesn't matter

      At a recent meeting of the U.S. House of Representatives Committee on Science, Space and Technology, Rep. Steve Stockman (R-TX) asked White House Science Advisor John Holdren why "global wobbling" was not included in climate models of modern climate change (You Tube). After all, if global wobbling was so important in ending the last ice age, why does it not matter now. The answer has to do with timescale. Dr. Holdren did an admirable job answering this question during the hearing, but... Continue Reading...

      Uncertainty doesn't imply nothing is known or nothing should be done

      While Judith Curry brings up some interesting notions in 'Climate Sensitivity Uncertainy', I don’t agree with many of her arguments and conclusions. I’m pleased that Dr. Curry acknowledges that “uncertainty in itself is not a reason for inaction” (see also 'Why Climate Uncertainty is No Excuse for Doing Nothing' on TheConversation.com). I do find that conclusion slightly at odds with her frequent calls to put less effort in mitigation. Curry says that “deep uncertainties remain”, while at the same time... Continue Reading...

      What climate scientists are saying about the global warming "hiatus"

      What are our readers to make of the hiatus in global surface temperature rise? What's often heard in my neck of the woods is something along the lines of what Dr. Neil Frank, former KHOU-TV meteorologist and beloved Houston personality, wrote in the Houston Chronicle last Friday: Dr. Neil Frank, former Director of the National Hurricane Center, and former Chief Meteorologist at KHOU-TV in Houston. "If global warming will be as catastrophic as some suggest, I have one question: Why... Continue Reading...

      Climate Sensitivity Uncertainty

      In a press conference ahead of the UN Climate Summit two week ago, UN Secretary-General Ban-Ki Moon stated: “Action on climate change is urgent.  The more we delay, the more we will pay in lives and in money.” The recently appointed UN Messenger of Peace Leonardo DiCaprio stated “The debate is over. Climate change is happening now.” These statements reflect a misunderstanding of the state of climate science and the extent to which we can blame adverse consequences such as extreme weather...
