Oh that really is very nice. A lot of food for thought, brilliantly displayed.

Neat.
Worrying.

Jeffrey Kiehl wrote:Earth’s CO2 concentration is rapidly rising to a level not seen in ∼30 to 100 million years, and Earth’s climate was extremely warm at these levels of CO2. If the world reaches such concentrations of atmospheric CO2, positive feedback processes can amplify global warming beyond current modeling estimates. The human species and global ecosystems will be placed in a climate state never before experienced in their evolutionary history and at an unprecedented rate. Note that these conclusions arise from observations from Earth’s past and not specifically from climate models. Will we, as a species, listen to these messages from the past in order to avoid repeating history?
No.

Oh dear. That graph shows a correlation between CO2 emissions and my age. It's not pirates causing the problem, it's me

Well not quite, but the graph shows it growing from around the time I was born!
