Most profound point: “In the past, when CO2 levels rose higher than they are today, it often happened over millions of years and the various forms of life on earth were able to evolve and adapt. But there were a number of times when CO2 levels and temperatures rose as quickly as they have risen in the last 100 years. These changes had profound consequences leading to mass extinctions. For example, 252 million years ago there was a rapid rise in CO2 due to a series of volcano eruptions, and global temperatures rose 11 deg. C wiping out 95% of all species on earth.”
