Climate Change and Human Extinction

Recently, respected scientist have started to believe that in the long term, Earth will warm to far higher temperatures than previously expected, possibly increasing by 10 degrees Celsius. No one seems to have researched what a 10 degree Celsius warmer would look like. However if it is possible for humans to survive on anywhere, they will need to live a completely different existence. I think humans might have a very precarious future.
