Climate change?

There seems little doubt that our climate is changing, but opinions seem very polarised between those who are very worried by this and those who who see it as little threat. One issue is that the world has, apparently, warmed less than expected and sea levels have risen less than suggested.

I am open-minded, but tend to side with those who think we should consume less carbon dioxide and fossil fuels. If the world became more hooked on renewable energy sources it would be no bad thing.
