1. Planetary scientists tell us that all the planets are experiencing some temperature increases. Apparently Republicans are universal.
2. Who says the current temperatures are so great?
3. When the glaciers melted after the last ice age, who caused that? Republicanis Neanderthalis?
4. The global temperature during the age of dinosaurs is estimated at 10 degrees greater than it is now. The dinosaurs hadn't even turned into petroleum at that time, so it must have been Republicanus Rex.

Me, I think global warming is caused by all that gas the Democrats are expelling.
