One of the papers that looks at the drought shows that the event truly was rare. It estimates that, were the climate stable, events like it would only come along every 420 years, and we'd be unlikely to see another for at least 285 years. Another paper fed climate models the sea surface temperatures that prevailed at the time, showing that they reproduce the ridge and the lack of rainfall. Since the sea surface has been warming along with the climate, you might think that would point a finger at climate change. And, to an extent, it does. … [Read more...] about That’s some weather we’re having. Is it climate change?
The solutions that are now being considered are based on the energetics described above. The simplest to understand is the option of placing a heating element inside the box, which would raise the temperatures above the point where clathrates are stable. An alternative is to pump a partly polar molecule, like ethanol or methanol, into the site. Because these can interact with both water and methane, they keep the stable cage structures from forming. Both of those aren't long-term solutions, since they require constant attention, but they could serve as stop-gaps until a permanent fix is put into place. … [Read more...] about Frozen methane, from the gulf oil spill to climate change
Amazon and Global Optimism on Tuesday announced that tech giant Infosys became the second major signatory to 'The Climate Pledge, making a commitment to meet the Paris Agreement 10 years early. The Climate Pledge calls on new signatories to be net zero carbon across their businesses by 2040a decade ahead of the Paris Accords goal of 2050, the three organisations said in a statement. Infosys and other companies that sign The Climate Pledge agree to measure and report greenhouse gas emissions on a regular basis, it said. They will have to implement decarbonisation strategies in line with the Paris Agreement through real business changes and innovations, including efficiency improvements, renewable energy, materials reductions, and other carbon emission elimination strategies. They also need to neutralise any remaining emissions with additional, quantifiable, real, permanent and socially- beneficial offsets to achieve net zero annual carbon emissions by 2040. Commenting on it, Amazon … [Read more...] about Infosys signs The Climate Pledge
So overall, the Committee for Skeptical Inquiry is right: denialism like Inhofe's deserves to be called out for what it is. But the world rarely breaks down into binary distinctions, and nowhere is that more true that human behavior. By choosing any one term for a spectrum of behavior, you'll undoubtedly get things wrong. In fact, you'll also get some things wrong about individual people, who may shift categories over time. (For example, Anthony Watts was originally a semi-skeptic about the reliability of our temperature records, but as he has continued questioning them even as more data on their reliability came in, he's moved into the denialism camp.) … [Read more...] about Skeptics, deniers, and contrarians: The climate science label game
But not before taking a parting shot at the media. Writing that he would "like to personally protest against how the authors and like-minded climate skeptics have much exaggerated the paper’s conclusions in public statements," he specifically cites the University of Alabama, Huntsville press release and Spencer's writings on his website as part of the exaggeration; the Forbes article that triggered our own coverage, along with a follow-up from Fox News, also get singled out. No one result created our current understanding of the climate system or provided evidence that it's being forced by greenhouse gasses; as a result, Wagner argues, no single result is likely to tear it down. … [Read more...] about Editor who published controversial climate paper resigns, blasts media
