I thought the conservative position was that there is no global warming
I always understood it to be that global warming wasn't the result of man, like the left crys about. Not that is wasn't occuring.
There is a recent short-time period in which average global temperatures have risen. However, if one considers a time period of hundreds of years rather than a dozen, then there is no overall increase.
The term "global warming" in common parlance has come to mean "human caused global warming". In reality, humans have very very little effect on global temperatures, but anti-industrial pseudo-environmentalists have successfully promoted their lies.
The conservative, truly scientific position is that we do not have enough data to know.
As near as I can tell, the position of global warming religious advocates is that the climate of the earth has not changed for billions of years, and it is only now that temperatures are fluctuating, and first world pollution is the problem.
Uncbob, the term "Global warming" does not refer to an increase in temperatures over a period of time (however they may be measured.)
It refers to a specific hypothesis, namely that human activity is causing the climate of the earth to change for the worse.
The conservative position is that this hypothesis is unsubstantiated and that the leftist attempt to use it to undermine the free world should be opposed.
