the planet is in an ever changing, constantly evolving, state of flux and has been for eons.
looking at cherry picked 'data', for the last couple of decades, to suit their current argument, is utter bollocks when compared to previous timescales of centuries and millennia.
We are still emerging from the 'mini-ice age' of the 1800,s (look back a couple of pages here, for the data) and it has been seized upon as a means to control and tax the **** out of the populous at large and keep the masses downtrodden, whilst those doing it continue to do WTF they like ... see how popular the theories'd be if they suddenly lost their limos, private jets, etc. and had to ride the busses or fly economy. ........ the whole thing is utter contrived sh1t, with the 'real', meaningful data being suppressed/buried/ignored to suit the BS

they'll be blaming plate techtonics on the weight of vehicles and people moving about on the planet shortly
