You can travel to New York City or even look up pictures online of glacial striations ain exposed boulders in New York City Central Park. This is settled science that 20,000 years ago 15,000 feet of ice sat on top of New York City. Are you trying to tell me all that ice melted because caveman were driving Hummers?
Yes, the earths climate changes back-and-forth over the millennia. It’s still on a warming trend. A natural warming trend. Perhaps a couple more big volcanoes will send us back into an ice age.
Please ask climate guru Al Gore, how much money he makes promoting global warming/climate change. Then tell me he doesn’t have a vested interest in promoting climate hysteria.
