What Carney was trying to say London will be under water.
atmospheric CO2 is at its highest level in 15 to 20 million years (Tripati 2009). (A natural change of 100ppm normally takes 5,000 to 20,000 years. The recent increase of 100ppm has taken just 120 years).The last time CO2 was at this level was during the Pliocene Epoch of 2.6 to 5.3 million years ago—Antarctica was a plant-covered oasis, sea levels were an estimated 10 to 20 meters higher, and global temperatures were an average of 2 to 3 degrees Celsius warmer. In the Arctic, summer temperatures were a full 14 degrees higher than they are now.
Although our output of 29 gigatons of CO2 is tiny compared to the 750 gigatons moving through the carbon cycle each year, it adds up because the land and ocean cannot absorb all of the extra CO2. About 40% is absorbed leaving us responsible for 17 gigatons or 45 x annual UK emissions of 373m tons.
