Privileged Planet: factors controlling climate (Introduction)

DAVID: A complex of activities evolved the Earth which made it comfortable for us today.

dhw: May I respectfully suggest that this is NOT the message at all. The article lays great emphasis on the role carbon dioxide plays in our climate, and it traces the link way back into the history of Earth’s disastrous climate changes, all of which were previously caused “naturally”. The article points out that today’s climate change is man-made, and it is proceeding too fast for Nature to neutralize it. The list of past catastrophes provides a warning to us of an approaching catastrophe. The warming of our climate and the acidifying of the oceans will NOT make the Earth comfortable for us, and the implication would therefore seem to be that we should take action now to prevent a catastrophe on the level of those described.

DAVID: You have always been a catastrophe fan. The Earth is currently cooling again a bit due to a solar minimum of sun spots. I follow "Watts up with That" climate website which takes a clear view of the hysteria. My comment is still true. The Earth today is quite hospitable for us and has been for eons. The local high temperatures which are recorded are not total eEarth climate measurements. Satellite temps do not show a rise.

dhw: Sorry, I didn’t mean to start a debate on climate change. I was merely pointing out that the article was warning us of impending catastrophe, not telling us how comfortable we are.

I thought the information was of interest. I ignore the warnings, as not reasonable.
