Yup. I argued initially that global warming is real and suggested we may have F'ed up our own planet. I still believe humans are contributing to the greenhouse gasses, but I'm not sure there's much to be done. Our reduced use of fossil fuels will occur for other reasons anyway. It's entirely possible we are in a cycle of increasing CO2 anyway. Humans may have meerly given it a healthy push.

The theory I had accepted that attempted to explain glaciation cycles was: "gradual global warming eventually caused sufficient ice sheet meltwater to disrupt ocean currents causing climate changes in Europe and NA conducive to continental glaciation --which eventually restored ocean currents leading again to gradual global warming, etc, etc,.."

These cycles are tens of thousands of years and more. Statistically, our species will be lucky to last long enough to see any measurable piece of such cycles. And we certainly have time to adapt to the changes.

So I am going to avoid establishing future family estates in low lying coastal areas, tend to hang near large freshwater systems, and otherwise: ride, eat pie, repeat.
