This is because burning fossil fuels releases carbon dioxide into the atmosphere, and this pollution acts as a kind of blanket or greenhouse, trapping heat. Although there is no doubt that the world is heating up, there is uncertainty about the extent that humans are to blame, because we know from geological evidence that the global climate has gone though periods of great warming and cooling without human intervention. The ice ages are an example of this

The uncertainty in this range results from both the difficulty of predicting the amount of future greenhouse gas emissions and uncertainties regarding climate sensitivity.
