As we are nearing the end of the holocene interglacial period, and as earth is moving toward minimum obliquity in the current Milankovitch cycle, this is likely to occur very soon on geological timescales, and probably even in humanity's not-too-distant future.

That's why I don't put much stock in anthropogenic global warming. Climate change? Sure. It's been fluctuating for aeons. Thinking we'll even make a dent as we head back into the current ice age? Please...

Now, should we be good stewards of the planet? Naturally! Who wants pollution, trash, toxic waste, etc? But carbon tax credits and bovine flatulence? Kek!
