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.

You ever see interstellar? Bad news -- drought/blight/warmth could destroy crops...perhaps even be an extinction level event. Good news -- there is none.. likelihood of aliens or future humans saving us is next to nil. I think we have maybe 50 years till we're close to any near ELE but my kid might see it.

AFAIK, the current rate of species extinction is exponentially faster than the previous ones. So "perhaps" might not be a suitable word.

Would melting sea ice lead to a rise in sea level? The ice is floating, so it's displacing the approximately same mass of water as it contains. If it melts the overall water level shouldn't change.

This is correct, melting sea ice does not lead to a rise in sea level. It’s the melting of glaciers and ice sheets (on Greenland for example) that cause the sea level to rise.

No one seems to have said yet: Billions of dollars in immobile port infrastructure made useless and having to be rebuilt further inland

Nothing to see here folks, we're just "displacing" 15% [1] of the world population. What could possibly go wrong?

If the temperature increases several degrees, hundreds of million - maybe even billion - of people will be displaced not just from the coastlines, but also from areas becoming desertified. Can you imagine the economic distress, humanitarian crises, and the conflicts this can generate?

Too bad we can't create a dyson sphere that we could partially close to limit sun exposure enough to refreeze parts of the planet as needed and also use the sphere to power everything on earth.

What if some countries said "don't refreeze us, we're ok"?

As far as sea-level rises are concerned, the Arctic sea ice will probably be a net sea-level fall, except around the Equator. If all of the Greenland glaciers were to disappear, well then, we would see a sea-level rise, globally. But it would be distributed unevenly across the world. The higher levels would again be around the Equator with decreasing levels the further north or south of the Equator you go. But to get…

i would think that greenland melting wouldn't happen all at once (if that's what you're saying), but rather that due to higher average ocean temperatures more of it would melt in the summer and less of it would freeze in the winter, and cumulatively over years and decades it has a net loss of ice, and perhaps eventually loses most of it. am i missing something in your argument?

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 ridiculed.

‪What industry is contributing to climate change the most? Where is a good place to find data on this?‬

bitcoin

Oh please bitcoin doesn’t even approach the carbon emissions of the US military. Nobody ever points that out.
