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!

I found these to be helpful to think about what we can do as individuals to help fight against climate change:

From Nature Conservancy: http://www.nature.org/ourinitiatives/urgentissues/global-war...

From the EPA: https://www3.epa.gov/climatechange/wycd/

From the Canadian government: http://www.climatechange.gc.ca/default.asp?lang=En&n=D27052C...

If you mean what we can do specifically about the melting polar ice caps? Pressurize our government to make legislation that helps reduce emissions.

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.

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.

Seems reasonable to move to a higher ground and out of the way of flash flood areas.

Eat some sushi before the ocean acidification decimates the fish population.

The rest, who knows.

Celebrate the opening of northern passages to more sea traffic and the new access to new previously inaccessible resources?

Plants absorb carbon dioxide. Grow more plants.

Have less children.
