A point I have been repeating for a while. You can't out-think every problem. Often the solution is right there and no one wants it.

How do you get in better shape? Diet and exercise. Ok? What exactly was confusing? It's the same freaken solution that everyone has known forever. Hell Aristotle talked about the dangers of red meat. They hadn't even gotten to the point where they thought leaches worked and they knew that people who ate red meat all the time had medical problems.

There are lots of great solutions to climate change from stuff that just buys us a little more time (plant a billion trees) to long term solutions (nuclear and renewables) to hell mary solutions (climate engineering). And we have tried none of them.
