La thèse du réchauffement climatique anthropique
Un article de Wikipédia, l'encyclopédie libre. Le réchauffement climatique , également appelé réchauffement planétaire , ou réchauffement global , est un phénomène d'augmentation de la température moyenne des océans et de l' atmosphère , mesuré à l'échelle mondiale sur plusieurs décennies, et qui traduit une augmentation de la quantité de chaleur de la surface terrestre.

After some prolonged deliberation, I have decided to withdraw from participating in the Fourth Assessment Report of the Intergovernmental Panel on Climate Change (IPCC). I am withdrawing because I have come to view the part of the IPCC to which my expertise is relevant as having become politicized. In addition, when I have raised my concerns to the IPCC leadership, their response was simply to dismiss my concerns. With this open letter to the community, I wish to explain the basis for my decision and bring awareness to what I view as a problem in the IPCC process. The IPCC is a group of climate researchers from around the world that every few years summarize how climate is changing and how it may be altered in the future due to manmade global warming. I had served both as an author for the Observations chapter and a Reviewer for the 2nd Assessment Report in 1995 and the 3rd Assessment Report in 2001, primarily on the topic of tropical cyclones (hurricanes and typhoons).

Japan’s boffins: Global warming isn’t man-made

We have reported on many occasions about the climate history of Antarctica, basically concluding that the frozen continent was not warming up during the most recent couple of decades, despite expectations that it should have been. At first glance, a new paper by the University of Washington’s Eric Steig and colleagues, published in last week’s Nature magazine and featured as its cover story, may seem to challenge our understanding—at least that is how it was spun to the press (see here and here , for example). But a closer look at what the paper really says—as opposed to what is said about the paper—shows that there is not much in need of changing with the current understanding of Antarctica’s temperature history.

Climate Progress recently reported on a study that found both economic and environmental benefits if homes in the northeastern United States upgraded older heating systems by moving from heating oil to switchgrass. However, one point to emphasize was the findings were specific to those circumstances — the region, the homes, and that particular use. Switchgrass was not nearly as good an idea for electricity generation or transportation fuel.
