I think knowledge about temperature is sufficient. The level of uncertainty is not high enough to support much continued debate about AGW except among specialists who really want to get down to the nitty gritty. At the level involved in policy decisions - it’s nonsense.
You realize the debate is over ONE degree celcius, right? The US is considered to have the highest quality system in the world and yet only 13% are within 1 degree of accuracy. So how in the world can anyone say we have gone up .2 degrees, or .6 degrees? It’s like measuring microns with a ruler.
