We are currently in the Holocene epoch which dates back about 12,000 years when the glaciers began to recede. Not our fault. But that is when humans began to thrive. There have been world droughts lasting about 100 years, about 4,200 years ago, again, not our fault, and mini ice ages in the 1,500’s, again, not our fault. Borings show huge temperature variations throughout the history of the earth and that will not change. No one knows why the Holocene period began and no one knows when it will end. I think worrying about it does not make sense. You want to have an impact on quality of life, stop using disposable plastics.
