Cool Feedbacks

Just a quick note to say that I am working on a climate feedback post. There are a lot of cool feedbacks, so to speak. One of the basic ones is that water vapor is the most important greenhouse gas. A warmer planet means warmer air which holds more water vapor, leading to increased warming. But, more water vapor could also lead to increased cloudiness. If those are high clouds then they trap heat and have an insulating effect, warming the surface, but if they are low clouds they cool the surface by reflecting sunlight.

Have been busy throwing a 'robot' birthday party for a group of 9 year olds, preparing a bunch of 20 year olds for an exam in molecular physics, getting the lab ready for a visitor from Tokyo, representing class 2b at the school council meeting, chasing kids around, commuting, etc. etc. But you, the readers of LB, have never been far from my thoughts.
