Sur la question du doute et des changements climatiques, voici le site Climat Sceptique. Intéressant, créé par un journaliste indépendant, Charles Muller, qui prétend présenter "l'état réel de la planète"…
Par la même occasion, j'en profite pour vous partager cinq nouvelles intéressantes reçues aujourd'hui par courriel, à travers une lettre d'information…

(Guardian — August 15, 2006)
More than half of the world's major forests will be lost if global temperatures rise by an average of 3C or more by the end of the century. This prediction comes from the most comprehensive analysis yet of the potential effects of human-made global warming. Extreme floods, forest fires and droughts will also become more common over the next 200 years as global temperatures rise owing to climate change.
Antarctic Snowfall Snafu Derails Climate Models
(Science Agogo– August 11, 2006)
An improved method of measuring Antarctic snowfall has revealed that previous records showing an increase in precipitation are not accurate, even over a half-century. Improved analysis of ice cores and snow pits revealed that precipitation levels in the Antarctic have in fact remained steady.

(BBC — August 11, 2006)
The meltdown of Greenland's ice sheet is speeding up, satellite measurements show. Data from a NASA satellite show that the melting rate has accelerated since 2004. If the ice cap were to completely disappear, global sea levels would rise by 6.5m (21 feet).

(ABC — August 11, 2006)
A conservative estimate is that about 10 percent of the aspen in Colorado may have died or become afflicted with something in the past 5 to 10 years. Possible causes include a fungus, hungry caterpillars, drought, man's interference with the natural cycle of forest fires, and even resurgent herds of hungry elk nibbling saplings to death.

(Washington Post — August 04, 2006)
Heat waves like those that have scorched Europe and the United States in recent weeks are becoming more frequent because of global warming, say scientists who have studied decades of weather records and computer models of past, present and future climate.
