There is no denying that the earth is warming.
You only have to look at the photos of glaciers and mountain tops and compare them to photos take 50 years ago.

The weight of scientific opinion is with global warming being man made. Of course there are dissenters from the scientific community.

Much the same situation as with smoking back in the 60's and 70's.

I had a neighbour who said to me for years "I have been smoking for 40 years and look no problems". A few months back he came and saw me and said " ignore what I have been telling you about smoking, I have lung cancer."

I do not want the earth to be in a similiar position in 40 years. The worst that can happen if we act now is that we can have a cleaner planet. After all what is money when compared to the health of a individual or in this instance our planet.
