Global Warming Proven?

My initial reaction was that this was important confirmation of the whole global warming thing, but then I noticed how close the thermometer apparently is to all that blacktop, so maybe we need to throw this one out. (photo courtesy Dave Thomas)

Weitzman and Ahab

Martin Weitzman’s paper on the economics of catastrophic climate change is rather like Moby Dick – something we all nod to knowing references while we’re secretly saying to ourselves, “WTF? Did you actually understand this?” I actually went so far as to enlist an environmental economist of my acquaintence (being a journalist has its advantages). …

Gristmill Scorecard

Given David Roberts’ apparent conversion to the view that simply everyone who matters in the climate change community agrees that the need to adjust to the problems being caused by climate change (“adapt”, in the lingo) shares equal importance with the need to reduce greenhouse gas emissions (“mitigate”), I thought a scorecard of Gristmill’s coverage …

Tail Wags Dog

Just when you thought this whole adaptation-mitigation discussion could not get more absurd comes this document from California’s state government interagency Water-Energy Subgroup of the Climate Action Team (WET-CAT). California faces some potentially serious climate change-related water problems, and the new report suggests some useful approaches to reduce the state’s water consumption. The reason? Reduced …

New Mexico’s Climate Change Initiative

I’d like to offer up a very concrete example that illustrates the problem with the current dynamic in the political debate over the extent to which thinking about adaptation should be explicitly made a part of the political discussion about our societal response to climate change. I wrote a story for the newspaper a year …

Happy Birthday to the Keeling Curve

Charles Keeling’s Mauna Loa carbon dioxide record is a tour de force, one of the great works of science of the 20th century. It shows the inexorably rising levels of carbon dioxide in our atmosphere. But its iconic status today derives from hypotheses confirmed and ideas well understood, things that were anything but certain when …

Adaptation v. Mitigation, Episode XVI

David Roberts and Roger Pielke Jr. took another turn around the adaptation/mitigation block today. Roger argued, as he has for some time, that adaptation to the problems caused by climate change needs to be given the same due in policy discussions as attempts to reduce greenhouse gas emissions (“mitigation,” in the parlance of the field.) …

Phase Three: Profit!

I’m a little bit suspicious that we’ve got one of those “underpants gnomes” business models here, but whatever.  Keith Johnson reports on some moves by big-time financial players into the carbon market: Merrill Lynch launched a new carbon-market index aimed at giving all sorts of investors access to the carbon markets. Meanwhile, J.P. Morgan said …

Yet Another Thing the IPCC Gets Wrong

A new paper by Maximilian Auffhammera and Richard T. Carson suggests that China’s greenhouse gas emissions are rising much more quickly than presumed in the IPCC’s emissions scenarios. A reminder that The IPCC’s “mistakes” don’t all break in one direction. The common rhetorical conception has the IPCC’s errors uniformly overstating the effects of greenhouse emissions …
