well things oscillate back and forth, from cold to warm and back again, like a pendulum in an old clock. I believe global warming trends occur naturally, just as global cooling trends occur naturally, however the speed and intensity that our current warming period is occuring at leads me to believe human industry has artificially sped up this process. So what might have taken centuries or millenia to take place may happen in under a century or two because of human activity. So might an unnaturally fast warming period lead to an unnaturally fast cooling period down the road? very possible, but the future is very hard to predict and im not a climatologist
