The thing is that everything is in a flexible but delicate balance, of sun radiation warming and space cooling, co2 and other gases keeping heat in, pollution cooling the sun's radiation a bit, ozone blocking some UV radiation, other atmospheric chemicals affecting the reflecting / insulating abilities of the upper air, sea surface temps., deep sea temps., ocean current flows (like Humboldt current), regular weather activity, and many other inputs.
A bit like we animals are just a bag of chemicals in a fine balance, and when the balance is lost, things don't run so well. You may get a mass ejection.
Because winds gust, and tides surge, and clouds disappear, nothing is smooth regular flowing, but constantly fluctuating over many time scales, so minor permanent changes can be disguised by short term variability, but the long term data doesn't lie. Certain numbers can be cherry picked from small data sets, but time really will tell.
Some people will benefit from 'global warming', just like people benefit from war and anything they can, and that doesn't mean it's all BS, just that it can be an opportunity.
The insurance companies are taking it seriously, preparing for stronger storms and damage.
Countries in constant drought are taking it seriously.
Pacific Islanders are taking it seriously.
As serious as American politics is [ha ha], no political fools have invented or taken over climate change or global warming. It is real.
AND No America, the world does not revolve around you.
