In daily life I hear lots of opinions on this subject. I know educated people who think:
1 - It is all nonsense.
2 - The climate is changing but it is not caused by man.
3 - The climate is changing as a direct result of man.
4 - Don't care about it at all. It is no big deal.
This is slightly surprising as the goverments, scientists and media of the world seem to be mostly in agreement with 3.
I wonder what people in here from different parts of the world think... Are you in one of those categories?
If you take the threat seriously, how have you changed your behaviour? Is this an issue in your area?
