@gordo999 What on Earth are you talking about? "Trapped by glass and warms the air" ? Are you talking about an actual green house?? You may want to read this. https://climate.mit.edu/ask-mit/how-do-greenhouse-gases-trap-heat-atmosphere Global warming is real there is no doubt about it. But it has nothing to do with ice ages. Read here if you're interested https://eos.org/research-spotlights/how-variations-in-earths-orbit-triggered-the-ice-ages The issue I have with the whole theory of global warming is CO2 as a pollutant . It's downright idiotic and was presented by Gore. Can humans destroy the planet by warming it. The answer is No. It's always been no, CO2 has been higher in the past when humans were not around and it was perfectly fine. Just because your beach front property is going to be under 10 feet of water 100 years from now is no reason to say the world is ending. You're in the wrong place, move ! Glaciers have melted and reformed multiple times in Earths history, why should that not happen again? Humans sometimes behave like the world was created only for them and everything on it should conform to whatever humans do. Hurricanes should not go thru certain spots because the humans sent a memo to the weather God! Apparently destroying forests and displacing or destroying millions of animals is not that important. But that damn beach front house needs to stay for eternity. Stupid humans, all hail the rise of synthetic lifeforms.
