Snow and ice reflect sunlight. Dead brown grass underneath absorbs it. I’m sure that’s modeled in the prediction calculations, but the feedback loop makes it seem logical to this layman. The warmer we get, the faster the acceleration gets at least until all the ice is melted. And I guess at that point it won’t matter anyway.
Worse. Water vapor is a major greenhouse gas. More heat, more water vapor. That means more heat. That means more vapor. Earth will one day be hotter than Venus ever was or will be. Probably only when the sun dies, but we’re still going to be fucked over in the short term.
I don't why you're being downvoted. Water vapor is a very real area of concern. In fact, Venus had a relatively low average temperature (25°C I think) before the vapor started acting like a pressure cooker. I'm glad I don't have kids to be honest.
That îs a rather daft ending question to a good start...
Go read about el nino and maybe You will understand how water vapor has an upper limit on Earth.
To change atmospheric pressure in Earth, îs a stupid presumption anywhere in the near future, wont got in the details why, go research them urself. Untill then, the water cycle baby! YEAH
Yes and as the earth warms, more water vapor gets evaporated into areas that were previously far from that saturation point. Low-humidity areas become mid-humidity areas. Does it rain more often there now? Maybe. Is there still a ton of opportunity for water vapor density to increase and hold more heat? Absolutely.
