The solution is basically the same as the solution to the global warming problem; we need to transition away from fossil fuels, and move to some combination of renewables and nuclear power for generating electricity, and probably electric cars for transportation.

I think it's going to happen, but the real question is, is it going to happen in time. So we need to speed the process of transition up.

Politically, the ideal solution would be some kind of either carbon tax, or cap-and-trade, to create a cost for carbon and encourage non-carbon solutions. Other then that, there are a lot of smaller but important issues that make a difference. Encouraging subsidies for solar and wind, and encouraging state laws that support rooftop solar are big ones. (For example, "net zero metering" is a key one, that's what lets you sell solar energy back to the grid when you produce more then what you need; some states are trying to get rid of that, on the request of the utility companies.) Things like higher gas taxes also help, as do tighter regulations on coal plants. (The EPA is creating regulations to limit how much carbon coal plants can put out, which is likely to really help a lot.) Also, the fight over Tesla to sell cars directly to consumers is a political issue that could help speed up the adaptation of electric cars.

That's just touching the surface, really; there are a lot of political issues involved here. Basically, anything that makes renewables or nuclear cheaper or easier, or that makes coal, oil, and to some extent natural gas more expensive, helps.

There are also things you can do as a consumer to help. Both by conserving power when you can and using less stuff, especially stuff that is one-use and disposable, and by supporting more eco-friendly options. But the real key is probably going to be on the political and technological fronts.
