Again: every time I see posts about Global Warming/Climate Change/Insert Scary-Sounding Term Here, no matter whether pro or con, I have to mention the most ABUNDANT most POWERFUL greenhouse gas there is in the Earth’s atmosphere. Unlike CO2, it’s not a tiny fraction of a percent but varies from very low to saturation. Yes, it’s good old H2O, in water vapor form.
Humid locations hold in more heat than dry ones, all else being equal. Of course, some so-called scientists point to Venus. Do they forget that Venus is not only closer to the Sun but its atmosphere is mostly CO2? Not a tiny percentage. Very different mechanisms, very different outcome.
As for Earth and its trends, I invite you to google “hockey stick climate graphs” and see what comes up. Funny how a trend can magnify if you don’t extend it so the whole picture is visible. What, 5000 years ago it was warmer than it is now? Gotta hide that from the public.
Does climate change over time? Of course. Are the doomsayers a front for those seeking power? Certainly. As always, follow the money.
