I also dig the bs about std dev's and all that. As if you had a real interest in the stats.
Here's a real real simple test you can run at home, since ALL of the data is free and publicly available. CFC's were banned in 1990. Now, if CFC's are greenhouse gasses on their own, and CO2 is also a greenhouse gas, then what you should find is that before 1990 the correlation between CO2's rise and temps rising is weaker than after 1990, because a piece of the pre-1990 rise would have been attributable to CFC's.
Here's the data, via the CORREL function in Excel. Even the numbnuts (ex futurecurrents) arguing here can figure out how to use it, I'm sure:
1959 to 1990: 75% correlation between CO2 and rising temps.
1991 to 2010: 81.5% correlation between CO2 and rising temps.
So there you have it. Now that CFC's are banned, the link between CO2 and rising temps has increased, proving both that CFCs were greenhouse gasses on their own and that CO2 is too.
Another test: the rate of increase in temps should have decreased since CFCs were banned as well. This wouldn't prove by itself that CO2 is also causing warming, but the evidence that banning CFCs caused the temperature rise to slow down should give pause to anyone believing the claptrap put out by the gulls who actually believe the Koch brothers.
Here's the data:
Rate of temp increase, 1959 to 1990: 12.7% compounded over a century.
Rate of temp increase, 1991 to 2010: 5.06% compounded over a century.
Ironically, it seems that the success we've had in slowing down that rate from banning CFC's (which these people would have opposed with the same arguments, and did at the time) has given the reactionaries an opening. More's the pity.
