Bevedere: What else floats?
Villager 2: Small rocks!

According to NOAA research - balloon and satellite temperature readings over the past 20 years - there has been no measureable increase in the temperature of the troposphere (1 miles to 5 miles up) which is where the CO2 accumulates and which would have to heat up to be responsible for the apparent global warming we are experiencing. The conclusion is therefore inescapable that global warming due to your SUVs or CFCs in highly overrated. On the other hand, astronomers have shown an almost seamless fit between variability in the sun's output and major climatological events over the past 150 years.

It seems to me that the conclusion that the events we are seeing are actually naturally variability in climate is pretty hard to avoid.
