So if the earth heats up, and more water evaporates, and more clouds form to block the sun, will this lead to a global cooling effect? My understanding is this was the old worry, that all our pollutants were going to block out the sun and lead to a new ice age, or at least the Matrix.
The heat spikes in the Arctic now so early on in the year and the jet stream which previously brought cold towards the Arctic now shifts the cold down in cold spikes and record cold fronts to north east and Europe. It seems we will no longer have an Arctic soon and the jet stream will be permanently shifted due to anthropogenic climate change. We had record heat in Southern California in early February and around the…
Where did the jet stream previously get the cold to bring to the Arctic?
I often see people talk about potential positive feedback loops involved in climate change, but rarely are potential damping mechanisms mentioned. So let's talk about them. I'll share one. Methane consuming bacteria discovered under the West Antarctic ice shelf: https://nsf.gov/news/news_summ.jsp?cntn_id=242668 "The scientists say that if their analysis is correct, it could mean that a large reservoir of methane thou…
Another dampening mechanism. It turns out burning all that fossel fuel dims the sky. So while we made it hotter , we also have been cooling. Which means when we get off fossil fuels, the earth will warm faster and all that built up CO2 will reach it's full warming potential.
Depends on how we burn it. See https://en.wikipedia.org/wiki/Global_cooling
We no longer produce sufficient SO2 due to clean coal plants and cars, so we have a problem.
So it's going to get warmer, sea levels will rise. coastlines will move inland as sea levels rise. Typically colder areas will become more tropical. Other than displacing a large number of people who live on coastlines, what's the big deal? Insult me for my niavety if it makes you feel better, but I honestly don't know the answer.
A huge part of world's population lives on coastal cities. When cities like Mumbai and Dhaka will start to submerge, you can imagine the havoc that will cause. Also, some countries like maldives will completely submerge. I don't think europeans would be very happy about accepting these people, given the situation that has arisen from Middle eastern migration. A lot of wildlife requires specific environmental situatio…
Actually, no, I can't. This won't happen overnight, cities will just slowly move away from the coastline. It will take hundreds of years to cover such cities with water (if ever).

It is interesting the other comments in this area are vague and emotional, whereas the only thought out comment is downvoted because it is critical of global warming. This constant dynamic is what makes me skeptical of the whole global warming thing.
Comments criticizing evolution in favor of intelligent design will also be downvoted for the same reasons. The scientific consensus is that climate change is happening, and it's caused by us. The evidence in favor of the theory is overwhelming, so you'd have to publish a pretty substantial study, not a comment on an internet forum, if you would want to sensibly argue against anthropogenic climate change without being…

Clouds reflect sunlight but they also trap heat, by absorbing infrared radiation and re-emitting it. (In Winter, notice how much colder it is in the morning when it's been clear all night.)
What industry is contributing to climate change the most? Where is a good place to find data on this?
All the ones that make your life comfortable and convenient.

Well, I'm glad the consensus of scientists has never been wrong. It's also helpful the scientists can tell us who the true experts are, otherwise we'd never know.
