Science the IPCC's estimate of of total GHG (green house gas) five year growth projection five years ago was high compared to reality, it would be safe to expect the same in these guesses too.
You better hope these estimates are on the high side. In the last century we saw a 1 degree Fahrenheit rise in global average temperature. That's partly why the last 12 years were the hottest on record. A global temperature rise of 6 degrees C would be catastrophic. Forget growing grapes in Nova Scotia. There wouldn't be much left alive in the Southern half of the US.
