World Scientists Near Consensus on Warming

“Scientists from across the world gathered Monday to hammer out the final details of an authoritative report on climate change that is expected to project centuries of rising temperatures and sea levels unless there are curbs in emissions of carbon dioxide and other gases that trap heat in the atmosphere.” (New York Times) The central consensus is that carbon dioxide levels in the atmosphere are reaching twice preindustrial levels as a result of human activities, and that this will result in a 3-8 degree (F) increase in ambient temperatures. Where the consensus founders is on the extent of sea level rise and coastal impact. Some climate scientists fear that existing models are too conservative, in light of recent findings about the instability of Antarctic and Greenland ice caps. Competing agendas have led to leaks of information from the upcoming reports designed to be either as frightening or reassuring as possible. (Which would you rather hear?)
