Good question about the tidal wave. I'm not sure about that. From the article:
"When ice shelves lose large chunks, it does not raise sea level because these bodies are already afloat. However, the loss of an ice shelf can speed up the seaward flow of the nonfloating glacial ice behind it, and this ice can in turn contribute to sea-level rise. Researchers have estimated that the loss of all the ice that the Larsen C ice shelf currently holds back would raise global sea levels by 10 centimetres."
Fun fact: the US Midwest grows corn, which produces as much oxygen (absorbs as much CO2) as the Amazon Basin. During the summer anyway. So we're growing a lot of plants already.
Most of the oxygen we breathe comes from plankton. But we don't particularly care for or about the ocean -- we don't see it, and we can make money by ignoring its health.
And most of that corn goes to feed cattle, which produce methane (worse than CO2). So, what we do with the plants matters. Do we allow them to sequester the carbon or we put their carbon right back into the atmosphere?
Vote and argument publicly to being goal warming, and the short term costs of mitigation, into the public's mind.
Choose against far supply chains.
Go solar, ride public, and electric car of you have to, and consume as little materially as possible.
Travel little, and prefer train over planes.
It's a very small impact for one person, but if you multiply by /everyone/ it becomes large.
I worried about global warming 20 years ago, but there was so much unknown, that I decided to wait. Now, we know much better, and it's actually worse that we thought before!
At about 3.5 degrees warming, the global food supply chain breaks down. We're at 1 degree now, and get Louisiana floods. 3.5 is between 20 and 50 years off.
But, who needs food or social stability anyway? We're all rugged individuals who will survive alone based on low taxes and Freedom (tm)! So don't worry!
If it's all going to hell anyway, might as well enjoy it now, and if we're wrong after all, then that was the right choice.
Screw other people, I'm getting a SUV!
Simple - reduce greenhouse gas emissions by around 50-80%. If we achieved 100% tomorrow the earth would continue warming by another degree or two.
Achieving those levels of reduction will need changes to nearly everything we do.
We could start by ceasing deforestation and getting off fossil fuels as soon as humanly possible, but it wouldn't stop there. Oh, and stop electing politicians who claim climate change is a hoax.
We can either cut carbon emissions, or gamble on impacts of climate change. But given latency and positive feedbacks, restraint is unlikely. By the time that impacts are undeniable enough to motivate substantial reductions in carbon emissions, it will arguably be too late.

It's the American Way (tm)!

Eat some sushi before the ocean acidification decimates the fish population.
The rest, who knows.

If you mean what we can do specifically about the melting polar ice caps? Pressurize our government to make legislation that helps reduce emissions.
Nani?!
What do you mean it's never stopped changing in the entire history of the earth?
