Initially, conservatives claimed there is no climate change so nothing needs to be done[/qjuote]
Who ever claimed that the climate never changes?
Then they admitted there is climate change but man had nothing to do with it so nothing needs to be done
Of course it changes...but there is not a single piece of observed, measured data which supports the man made climate change hypothesis over natural variability...but feel free to look...it may be an eye opening experience for you...it was for me way back when.
Now they are admitting man has an impact but that nobody can be sure how much
We know how much...it is measurable in the heat island effect within large metropolitan areas...it is local...not global.
Eventually, they will admit that man impacted climate but it is too late to do anything about it
Hand waving, hand wringing, alarmist claptrap...nothing more..nothing less..
