I have a good background in geology and I know that the box in the bottom left of the
pic is nothing short of ridiculous!
The sun irradiates at a near constant level, what ever happens on earth, and volcanoes erupt regardless of how much the sun irradiates.
However, back on topic:
I don't think global warming is significantly a man made phenomenon.
However, I think we should act as if it where by cutting CO2 emissions etc.
Why?
Well:
1) I could be wrong.
Many people with my level of intelligence and knowledge about the subject think I am wrong
and many more people with better knowledge and intelligence than me think I am wrong.
Until the case is closed, I could be wrong.
2)a If I am wrong and we don't act, then we potentially have a lot to lose.
2)b If I am right and we do act, then we won't lose as much.
3) Scenario 2b is preferable to 2a
So, even tho I don't think global warming is significantly a man made phenomenon; the
rational course of action is to act as if it where.
