Roy Spencer is a climate scientist at the University of Alabama Huntsville who may be the world's most important scientist. He has discovered scientific insights and theories that cast great doubt on global warming doctrine... --snip-- The pressure that is building on climate doctrine is the failure of the Earth to warm, a trend that has now continued for 16 years. The longer warming is stalled, in the face of constantly increasing CO2, the harder it becomes for the believers to continue believing. Compounding the failure of the Earth to warm is the failure of the oceans to warm for...

Two things are happening that undermine President Obama and the Democrats’ attempts to control our lives via climate change policy. First, according to a Pew Research Center for the People & the Press poll, fewer and fewer Americans say global warming is a serious problem. Only 33 percent of Americans now say global warming is a serious problem, compared to 39 percent six months ago. And second, the globe is not getting warmer — or at least, it hasn’t in the last 15 years. As the March 30 print edition of The Economist reported, “Over the past 15 years air...

Emily Litella was the Saturday Night Live character who would spin out lengthy theories based on her misunderstanding of a word or phrase and, when her error was pointed out, would respond crisply, “Never mind.” The Economist, which I read and revere and for which I have on occasion written (they assign reviews of books by Economist writers to outsiders), has long been convinced that we on earth face a crisis caused by man-made global warming. Now the newspaper (as it refers to itself) seems to have reached an Emily Litella moment.“Global warming slows down,” reads a line on the...

The climate may be heating up less in response to greenhouse-gas emissions than was once thought. But that does not mean the problem is going away | OVER the past 15 years air temperatures at the Earth’s surface have been flat while greenhouse-gas emissions have continued to soar. The world added roughly 100 billion tonnes of carbon to the atmosphere between 2000 and 2010. That is about a quarter of all the CO₂ put there by humanity since 1750. And yet, as James Hansen, the head of NASA’s Goddard Institute for Space Studies, observes, “the five-year mean global temperature has...

In my Weekly Standard cover story about the fallout from the “Climategate” email scandal three years ago, I offered the following question by way of prediction: Eventually the climate modeling community is going to have to reconsider the central question: Have the models the IPCC uses for its predictions of catastrophic warming overestimated the climate’s sensitivity to greenhouse gases? The article then went on to survey emerging research (U.S. government funded!) casting doubt on high estimates of climate sensitivity, along with alternative explanations on some climate factors, such as “black carbon.” The question in my mind at the time was...

We are a little late to the party, but it is worth adding a few words now that our favourite amateur contrarian is at it again. As many already know, the Forum on Physics and Society (an un-peer-reviewed newsletter published by the otherwise quite sensible American Physical Society), rather surprisingly published a new paper by Monckton that tries again to show using rigorous arithmetic that IPCC is all wrong and that climate sensitivity is negligible. His latest sally, like his previous attempt, is full of the usual obfuscating sleight of hand, but to save people the time in working it...

A final dispatch from the International Climate Change ConferenceEditor's Note: reason Science Correspondent Ronald Bailey will be filing a series of regular dispatches from the Heartland Institute's controversial International Conference on Climate Change. Below is the final dispatch in that series.New York, March 4—Let's start with some possible news from Heartland Institute's International Climate Change Conference. In the context of man-made global warming, climate sensitivity asks how much temperatures increase if one adds a specified amount of a greenhouse gas. In general, most climatologists accept the proposition, all things being equal, that if one doubles carbon dioxide in the atmosphere...
