Interesting, at one time about 650 Million years ago the earth was covered with ice (one of thousands of Ice ages) and the only thing that kept life going was the vents under the ocean which kept enough heat to survive. Then as the sun went through one of its heating cycles the warming period came.
BTW, we are about 1,000 years past the average warming cycle so get ready.
Yeah, and we’re clamoring to stop the warming that may be forestalling the next Ice Age. It’s amazing creatures so stupid have lasted so long.
