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

Try a revenue neutral carbon tax.

In Australia we tried a scheme with very low economic impact (despite scaremongering to the contrary) carbon tax, which provably reduced emissions before its repeal.

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 the first step. It's like a fever in a human. 1-3°C is no big deal. 3-5°C is extremely serious. We're talking massive tectonic activity, volcanoes, and huge tsunami(s) caused by a huge wave of energy originating from Earth's core. This situation is caused by a problem in the circulation of the gravity field. I've met many scientists but aside from even finding people who understand this topic, I have barely even found anyone who genuinely wants to know either. And this is the very reason this phenomenon of collapse is determined to appear in this age of mankind.

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 .

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.

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?

As the sea level rises, its surface grows by the square. So, more and more water is needed for it to rise more. So, all linear predictions are flawed anyway. What do you think, the sea is suddenly going to rise by meters? Get a grip on reality. I really dislike these alarmist articles.

EDIT: Okay, I checked the math and the square really doesn't weigh much at this ratio of sphere radius vs. sea level rise. I guess I should rely less on asymptotes in the real world ;)

Still, I remain largely unconcerned about sea level rises since even if it were to continue linearly, it's completely unproblematic except for some coastal/below sea regions.

We're trying. The left opposes it because it doesn't make government bigger: https://www.washingtonpost.com/opinions/the-lefts-opposition...

I'm not ideologically in favor of smaller or bigger government. I want smarter government, and there's nothing smart about passing legislation that will reduce the state government's revenue by between $80 and $900 million a year without defining what services to cut.

Also, "bigger government" is a vague enough definition that it could easily apply to this initiative. It creates a new category of tax, and a new category of tax credit. It will probably reduce the government's revenue, but the legislature can and most likely will raise revenue in other places to plug the gaps rather than cutting necessary agencies.

Many nonlinear problems can be approximated as linear and in this case the rough sea level rise (think altitude/distance) so ridiculously dwarfs the radius of the earth (the square in your argument) that the linear approximation is pretty good.

Doesn't that assume perfectly flat coastlines?
