RE: Global climate change: a ticking time bomb #1
I am quite impressed that you read my post with utmost attention as to bring out these gray areas. Thanks a lot. Now let me address the issues raised one after the other:
About the earth experiencing warmer periods before now, you are quite right. Perhaps I should have said in the last few hundred years.
About heat generated from radioactive decay in the earth's crust, I do not know how much of heat generated becomes useful to the atmosphere really, you might want to enlighten me in that aspect
I mentioned that only small percentage of heat from the sun gets to the earth, yes. the 51% you are looking at is just a part of the small percentage that got to the earth. The 100% incoming solar radiation is actually a small percentage of original radiation from the sun. A large part has been absorbed or reflected back into space by the cloud and ozone layer.
I will like to hear further from you.

This link contains info about the different heatfluxes to the Earth's surface. Particularly figure 4. and comment 31. by Tom Curtis are quite useful. Turns out less than a per cent of the surface heat flow is coming from the Earth's interior (nowadays). My main point was to simply indicate there are more sources of heat than just the sun :)
