La thèse du réchauffement climatique anthropique

En 1988, l'ONU crée le Groupe intergouvernemental sur l'évolution du climat (GIEC) chargé de faire une synthèse des études scientifiques sur cette question. Dans son dernier et quatrième rapport, auquel ont participé plus de 2 500 scientifiques de 130 pays[1], le GIEC affirme que le réchauffement climatique depuis 1950 est très probablement[c 1] dû à l'augmentation des gaz à effet de serre d'origine anthropique. Les conclusions du GIEC ont été approuvées par plus de 40 sociétés scientifiques et académies des sciences, y compris l'ensemble des académies nationales des sciences des grands pays industrialisés[2].

Groupe d'experts intergouvernemental sur l'évolution du climat -

Le Groupe d'experts intergouvernemental sur l'évolution du climat (GIEC) est un organisme intergouvernemental, ouvert à tous les pays membres de l'ONU. Il « a pour mission d’évaluer, sans parti-pris et de façon méthodique, claire et objective, les informations d’ordre scientifique, technique et socio-économique qui nous sont nécessaires pour mieux comprendre les risques liés au changement climatique d’origine humaine, cerner plus précisément les conséquences possibles de ce changement et envisager d’éventuelles stratégies d’adaptation et d’atténuation. Il n’a pas pour mandat d’entreprendre des travaux de recherche ni de suivre l’évolution des variables climatologiques ou d’autres paramètres pertinents. IPCC - Intergovernmental Panel on Climate Change. - Prometheus: Chris Landsea Leaves IPCC Archives. After some prolonged deliberation, I have decided to withdraw from participating in the Fourth Assessment Report of the Intergovernmental Panel on Climate Change (IPCC).

- Prometheus: Chris Landsea Leaves IPCC Archives

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).

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.

Official An Inconvenient Truth: Global Warming Effect, Al Gore M. From director Davis Guggenheim, An Inconvenient Truth is a passionate and inspirational look at former Vice President Al Gore's fervent crusade to halt global warming's deadly progress by exposing the myths and misconceptions that surround it.

Official An Inconvenient Truth: Global Warming Effect, Al Gore M

In this intimate portrait of Gore and his "travelling global warming show," Gore comes across as never before in the media - funny, engaging, open and intent on alerting citizens to this "planetary emergency" before it's too late. Interspersed with the bracing facts and future predictions is the story of Gore's personal journey: from an idealistic college student who first saw a massive environmental crisis looming; to a young Senator facing a harrowing family tragedy that altered his perspective; to the man who almost became President but instead returned to the most important cause of his life.
