These impacts have been observed at CO2 levels that most Americans — and their children — are routinely exposed to today inside classrooms, offices, homes, planes, and cars.

They can also serve as an open thread so that we can keep each other informed on important climate news.

Clouds and climate sensitivity

Climate sensitivity is the temperature increase caused by a doubling of the trace gas CO2 in the atmosphere. The IPCC AR4 gave this as between 2 and 4.5 °C for short term “Charney” feedbacks, which is a large uncertainty range for such an important number. Clouds are largely to blame.

Recent research indicates less cloud cover as the sea surface warms. Thus uncertainty is taken away from the low side. Continue reading Climate clippings 6 →
