Caldeira: The Great Climate Experiment

We missed this when it came out a few months back byt better late than never.

If you missed it too, it’s worth a look: another future history, this one looking deep into the future, by Prof Ken Caldeira.

What are the ultimate limits of the change that we are causing? The best historical example comes from the 100-million-year-old climate of the Cretaceous period, when moist, hot air enveloped dinosaurs’ leathery skin, crocodilelike creatures swam in the Arctic and teeming plant life flourished in the CO2-rich air. The greenhouse that is forming now will have consequences that last for hundreds of thousands of years or more. But first, it will profoundly affect much of life on the planet—especially us.
