This is one of the single most common folleys-it being 90 degrees has absolutely nothing to do with climate, it has to do with WEATHER. There is a distinct difference between the two-
CLIMATE is the sum total of everything. Average temperatures, precipitation, etc. This remains (or is supposed to remain) relatively stable. The average global temperature is around 57ish (F) if I remember correctly.
WEATHER is the momentary state of the climate. You can't say "it's 110 degrees out, it must be global warming" any more than you can say "I woke up this morning and it was 20 degrees, global warming is a bunch of crap."
I cannot stress this enough-when the "global temperature rise" is spoken of, they're talking about an average, not a weather report.
And if I may be blunt, it is absolutely unacceptable to say this is a load of crap. Unfortunately, that is like saying you believe its crap that the earth revolves around the sun (actually some of those nutters do still exist!), or that the laws of Physics are crap, etc.
We're strictly (or at least I'm strictly) talking about measureable scientific FACT here, not theory. Global temp is rising, that is FACT. Th effects of even a couple degrees rise will be bad, FACT. How much it will continue to rise, how much are we contributing, what will be the long-term effects: THEORY. It is important to differentiate between the two before calling one or the other crap.
When George Dubya, the man with the power to change things does not believe, (mainly to do with business and how much they pay into party funds I suspect), then we really don't have much chance to change anything. Come to that, any President. Can't have
