i have only read the first one so far.

In contrast, tropical forests appear to be doubly valuable to the earth’s climate system. Not only do they store copious amounts of carbon, the roots of tropical trees reach down deep, drawing up water that they evaporate through their leaves. In the atmosphere, this water may form clouds that reflect sunlight back to space, helping to cool the earth.

in Al Gores book "An inconvenient truth" he seems to think that water in the atmosphere is a natural greenhouse gas. his logic is the sun is coming in and traped below the clouds.....
i see how colour and reflectivity can be a big impact, but if there are lots of various things in the air it is going to be reflected far less. the way i see it is this. if we stop putting water in the air we die (i know we dont put it in there....you know what i mean). if we stop putting other emissions in the air, CO2 for example, we live. Hope that came out as readable, its late sorry.
