There is overwhelming evidence that human activities, especially the burning of fossil fuels, are causing a rapid change in the Earth's climate. The evidence comes in three forms: studies of the paleoclimate data, much-improved computer models, and the latest field observations. The carbon dioxide level in the atmosphere is now at 387 parts per million--much higher than it has been in the last 800,000 years--and rising at a rate of 2 ppm per year. It has been projected that the accelerating ice loss now being observed will lead to a rise in sea level by 2100 of 1 meter or more. Regional climate models indicate widespread human hardship and exorbitant economic costs. In the face of climate change politicization and widespread misinformation, society must find the will to quickly address this mounting environmental and economic crisis.

There is overwhelming evidence that human activities, especially the burning of fossil fuels, are causing a rapid change in the Earth's climate. The evidence comes in three forms: studies of the paleoclimate data, much-improved computer models, and the latest field observations. The carbon dioxide level in the atmosphere is now at 387 parts per million--much higher than it has been in the last 800,000 years--and rising at a rate of 2 ppm per year. It has been projected that the accelerating ice loss now being observed will lead to a rise in sea level by 2100 of 1 meter or more. Regional climate models indicate widespread human hardship and exorbitant economic costs. In the face of climate change politicization and widespread misinformation, society must find the will to quickly address this mounting environmental and economic crisis.
