Playing Climate Change Catch-Up

Even the most uninformed student of climate change could tell you that the solution to global warming is to mitigate global greenhouse gas emissions, and fast. But the political difficulties of mitigation aside (the first major federal cap-and-trade legislation will be up soon in the Senate, and isn't expected to pass), the problem is that the sheer amount of greenhouse gases we've already pumped into the atmosphere has irreversibly bound us to a certain amount of warming over the next several decades — no matter what we do, we'll have to adapt to it.
