Volgens mij geven de onderstaande drie video's een goed overzicht over de AGW discussie.

Ik heb ze in volgorde gezet van inleidende documentaire tot meer over de wetenschappelijke feiten.

Get the anti-science bent out of politics

The basic physics and chemistry of how carbon dioxide and other human-produced greenhouse gases trap heat in the lower atmosphere have been understood for nearly two centuries. Overloading the atmosphere with carbon dioxide from burning fossil fuels is heating the planet, shrinking the Arctic ice cap, melting glaciers and raising sea levels. It is leading to more widespread drought, more frequent heat waves and more powerful hurricanes. Even without my work, or that of the entire sub-field of studying past climates, scientists are in broad agreement on the reality of these changes and their near-certain link to human activity.

Hal Lewis: My Resignation From The American Physical Society

"..

I do feel the need to add one note, and this is conjecture, since it is always risky to discuss other people's motives. This scheming at APS HQ is so bizarre that there cannot be a simple explanation for it. Some have held that the physicists of today are not as smart as they used to be, but I don't think that is an issue. I think it is the money, exactly what Eisenhower warned about a half-century ago. There are indeed trillions of dollars involved, to say nothing of the fame and glory (and frequent trips to exotic islands) that go with being a member of the club. Your own Physics Department (of which you are chairman) would lose millions a year if the global warming bubble burst. When Penn State absolved Mike Mann of wrongdoing, and the University of East Anglia did the same for Phil Jones, they cannot have been unaware of the financial penalty for doing otherwise. As the old saying goes, you don't have to be a weatherman to know which way the wind is blowing. Since I am no philosopher, I'm not going to explore at just which point enlightened self-interest crosses the line into corruption, but a careful reading of the ClimateGate releases makes it clear that this is not an academic question.

Dans les climats du passé, l’effet des variations de l’insolation liées à celles de l’orbite de la Terre est incontesté. En revanche, l’importance de l’impact des cycles de l’activité solaire reste en débat. L’émergence, depuis une vingtaine d’années, de données d’observation fiables, qu’elles soient satellitaires ou issues de grands programmes coordonnés au sol, permet d’aborder le changement climatique dans une démarche scientifiquement crédible. Les modèles, indispensables à l’interprétation des données en vue de projections pour l’avenir, ont progressé rapidement dans cette période. Concernant les gaz à effet de serre, dont le CO2 émis par les activités humaines, s’il existe un consensus sur leur impact direct, le rôle de leurs effets indirects est encore controversé. Parmi les mécanismes identifiés pour comprendre l’évolution du climat, la physicochimie des nuages est apparue comme une direction de recherche active et à renforcer.
