Could be, the theories of the Climate Cliff have been discussed for over two decades now, I remember one of the first articles in Omni Magazine. Shouldn't mankind stop polluting either way? Sure that is a good idea and it makes sense not to pollute doesn't it and we need to continue to do more studies on humankind's affects on the Planet.
Yes I agree we should study Mother Earth's head lice, mankind. And how the head lice is causing issues with the surface of the planet. But really this Earth goes thru cycles, the sun goes thru cycles too, the Earth travels thru open space in a cocoon of energy within the solar system, each region it passes thru changes resonance. There is space weather, solar flares and even the Earth's own geo thermo heat to deal with.
Some complain that the number of world-wide flights, trucks, trains, automobiles are causing lots of CO2 emissions also. Air travel at altitude does warm up things; contrails of planes show this. CO2 is not an evil in its self, some planets have CO2 atmospheres right and the Trees need CO2 and they return us the oxygen. Too bad we cut them all down for NYT newspapers or the utter blob of bureaucracy isn't it?
Much of the battle over Global Warming is a battle for power over power, there is a huge amount of money flow involved.
It's Time You Feared Global Warming!
