By "we" do you mean the few people reading this on the forum, or all of humanity? There are a number of actions that can be taken to keep things from getting too hot to handle. People seem to be under the mistaken assumption that AGW is a problem to be solved and then we can just go have a party of something and move on with our lives. It's more like a relay race for a world record or something. Each new technology or change gives us more time to get ahead of the problem. We may not see the end of the race no matter what, we can't even know if we're ahead really until 80-100 years from now, but we just gotta do the best we can on our leg and make things easier for the next runner when we pass off the baton. Getting as much coal (especially) and oil left in the ground as possible buys us more time before something bad happens. Advancing the tech for solar and wind or putting another non-fossil fuel power plant in place buys us more time. If we had to, we could go towards more extreme strategies like solar deflection or CO2 sequestering, but those are dicey at best. The end goal isn't a world without any problems, but some place where clean energy is everywhere and the potential for war, famine, and extreme weather is better than it otherwise would be. This isn't going to happen overnight, but then the problems that caused it started 100 years ago.
