There is nothing we can do, as long China and India get a pass, 3.2 billion people in 2 country doing nothing. Even if the US disappeared off the face of the map, its still to late. I say let it happen, it will propel us into a new era off innovation and environmental awareness. No one is going to take it seriously until its to late anyway .

They're building solar power plants everywhere, shutting down factories and coal power plants around large cities.

"Other main targets include: – reduction of emissions from coal burning industries and vehicles2 – boost cleaner and more efficient use of coal – promote the use of electricity and natural gas in place of coal – support for wind, solar and bio power sectors; increase in proportion of clean energy – encourage the use of waste straw as a resource – reduction in-field burning – implementation of control measures to deal with air pollution

...

By 2020, he said, the intensity of water use per unit of GDP will fall by 23%, energy intensity by a further 15%, and carbon intensity by 18%."

What about U.S.? It's people saying "as long China and India get a pass... Even if the US disappeared off the face of the map, its still to late... so let it happen."

You're the problem. Even if the rest of the world disappeared of the map, U.S.'s carbon emissions and pollution still exceed world's capacity to absorb it. Do you know how much of the world's environment is scorched to produce raw resources to produce goods for consumption in the U.S.? You're not taking it seriously.

Except India and China use less per capita than Westerners, and China is building low-carbon infrastructure mega-projects.

Just because 100 people are dropping candy wrappers at the park doesn't make it okay for you to dump a bag of garbage.

Duh. The important thing at this instant is to develop a self-sufficient extra-terrestrial colony or a means by which some people can survive far above the surface of the Earth for 30-80 years. Life on Earth itself has less time than most people are even ready to know. Something on the order of 1-10 years left. There are massive changes coming which will destroy all human civilization on Earth. Global warming is just…

Fascinating. Do you have any sources on this? I'm interested in learning more.

In terms of sea level changes, however, the study found the effects of melting are more drastically felt in regions farther from its source. Would be nice if they had a theory why.

Whatever it is, you can be certain that the solution is massive taxation and central control by bureaucrats.

Nothing will happen otherwise. We've already shown that.

It is a complex problem. As far as I understand, in the criticism to any work on climate change in the west (at least in the US) is that people are still debating if it is real or not, in the face of evidence; hence there's lack of political will. And, in countries like India or China, the criticism is that lots of people need cheap fuel to get out of poverty and imposing restrictions would impede that. Though, the per capita consumption is way less compared to countries like US. That said, I wouldn't say these countries are not doing anything. I can speak for India, for example, there is the Jawaharlal Nehru National Solar Mission[0] that is a goal to achieve 100,000 MW of solar power generation by 2022 and I see developments underway in many states in India. There are similar initiatives in other areas like Wind energy etc.

And, the defeatist attitude that no one takes it seriously, lets just do nothing and hope it works out is dangerous. As far as I can tell, the island nations will be the first affected, not to mention harsher weather, more storms, followed by massive shortages of food and water. I wouldn't be surprised if that leads to more wars than funding research and innovation.

Earlier quoted context omitted.

Part of the reason is gravitational effects. When a large amount of ice melts, the Earth's gravity is shifted away from that region. This gives you a sense of the absolutely huge amount of ice we're talking about. For example, if the West Antarctic Ice Shelf collapses we'll see about 10 metres of sea level rise, but mostly in the northern hemisphere. To underline just how much ice this is, this effect will slowly be…

This makes me wonder. Could it affect seismic activity?

Indeed it can!

"rapid deglaciation promotes earthquakes ... rebound stress that is available to trigger earthquakes today is of the order of 1 MPa. This stress level is not large enough to rupture intact rocks but is large enough to reactivate pre-existing faults that are close to failure."

Depends if your goal is to solve the problem or act morally.

Maybe I'm daft but one suggested itself to me: if you add more very cold water locally, that influences the temperature and pressure/density differentials with existing currents. It's presumably the effect on those currents that causes more water to build up elsewhere.

Gravimetry has been used to track ocean currents, and water temperature will presumably effect currents.
