La thèse du réchauffement
Get flash to fully experience Pearltrees
L'Académie des sciences a tranché. Dans un rapport de treize pages remis jeudi matin à la ministre de l'Enseignement supérieur et de la Recherche, l'institution conclut que « l'augmentation de CO2 et, à un moindre degré, des autres gaz à effet de serre, est incontestablement due à l'activité humaine ». Un désaveu pour tous les climato-sceptiques particulièrement virulents en France. Saisie au printemps par 600 chercheurs français travaillant dans le domaine du climat, Valérie Pécresse avait chargé l'Académie d'organiser une confrontation entre les climatologues et leurs opposants et d'en tirer des conclusions. Ce qu'elle a fait, à huis clos, le 20 septembre dernier. Les 600 chercheurs qui avaient interpellé la ministre désiraient en finir avec « les accusations mensongères lancées à l'encontre » de leur communauté.

La thèse du réchauffement climatique anthropique
Différence de température globale moyenne de surface par rapport à la moyenne 1961-1990, sur la période 1880-2009. 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 et sur plusieurs décennies, et qui traduit une augmentation de la quantité de chaleur de la surface terrestre.

IPCC - Intergovernmental Panel on Climate Change
The three Working Groups full reports and the Synthesis Report, the final part of the AR4, are available online (see here below).
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).

Exclusive Japanese scientists have made a dramatic break with the UN and Western-backed hypothesis of climate change in a new report from its Energy Commission.

By Stefan Rahmstorf and Dim Coumou One claim frequently heard regarding extreme heat waves goes something like this: ”Since this heat wave broke the previous record by 5 °C, global warming can’t have much to do with it since that has been only 1 °C over the 20th century”.
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.
