Global Warming for the nth time 

Global Warming for the nth time

Someone who doesn't work for polluters, via Hit and Run:

There is no proven link between human activity and global warming.

Global temperatures will likely rise by 1.4-5.8 degrees during the next 100 years. The average increase will be three degrees. I do not think that this threatens mankind. Sea levels, due to rise by 47 cm in the 21st century, will not threaten port cities.
