YouTube - Alarmist Richard Alley Dances to Explain Ice Ages, CO2 and Global Warming
The money quote (at the 3:30 mark): "The change so far is very small, but it's far enough that we can validate our models". Alley goes on to argue that uncertainty in climate science is a justification for spending MORE money right now (trying to stabilize climate by tweaking trace amounts of natural atmospheric gas).
