Its more to get people thinking about it than the actual decrease in Global Warming that it will actually cause.
Umm.......
We're no being affected by global warming........
Actually, we're being affected by global cooling.........
Whole bunch of stuff about that.
the global warming people want you to believe the following:
1) global warming exists
2) global warming is man made
3) drastic measures must be taken now to correct it.
The reality is:
1) The earth's temperature has been fluctuating since the beginning of time.
2) The sun probably is the biggest single driver in changing global temperatures (i.e. the temperature of Mars was rising at the same rate of the earth during the last decade or so).
3) it probably isn't worthwhile to take any steps to correct something we have no control over.
