I guess it ties into the “Earth has gone through several heating and cooling periods through the eons, so what we’re experiencing now is nothing new or unnatural” argument against AGW.
Which is an extremely dangerous attitude to have right now. Science says we have a couple years to prevent a tipping point in runaway climate change. The best case scenario is keeping it down to two degrees for the rest of the century (which will still be disastrous). Under Trump we are headed down the path to a six degree rise, which will jeopardize human existence, according to most climate experts.
You mean the same people told us the planet was cooling? Mega Hurricanes were on the way? The ozone layer was disappearing? The oceans would be dead by now? Arctic ice was disappearing? New York would be underwater by now?
