Something on global warming and climate change

Bryan Lovell, the President of the Geological Society of London discuss global warming in relationship to carbon emissions. He says that those who say, “We don’t know what happens when you pump several hundred gigatons of carbon into the atmosphere,” are wrong. We do know. “The rock record” shows an event 183 million years ago that gives us a benchmark for today. The planet warmed, the oceans turned acid, and there were many extinctions. These new findings, first published in 1999 and subsequently reconfirmed, give a clear model for what’s happening right now. The difference is only in the source of the carbon.
