Gareth, there are no facts to PROVE that MANMADE CO2 causes global warming! No-one is denying that there is a period of global warming. It's occurring now in the same way that global cooling occurred from the 1940s into the 1970s, when everyone became hysterical about the next Big Freeze. It's natural, it's normal, and there's feckall we can do to stop the Sun's power affecting us.
Everyone should be able to accept, regardless of any affiliations to companies, political parties, employers, etc., the simple truth that we were all taught in school: the Sun warms the Earth through its activity. Sometimes, its activity is much stronger for periods of time, and sometimes its activity is less. Thus, when it's very active, the Earth warms up accordingly. Now I don't think anyone would need a Ph.D to understand that. When the Earth warms up, the oceans release more CO2 which eventually rises (heat rises, heated water vapour rises, blah, blah) and enters the troposphere as entirely NATURAL, NORMAL CO2.
Warming occurs on the surface (of Earth) and permeates upwards - if somehow physics has been reversed, and warm air now falls down instead of rising up, I think we should be told, so that we can throw away the textbooks and rewrite history.
