For clean energy, there's an enormous amount of progress that is going to unfold over the next 10 and 20 years. It should be truly transformative, not just in an ecological sense but also in an economic sense. It'll be a generation too late to prevent the greatest damage to our environment, but it'll be just on time to prevent things from being even worse.

At some point the focus for greatest impact is going to need to shift to ways we can accelerate the removal of carbon from the atmosphere or other methods of counteracting the heating effects. This isn't one we can solve by simply planting a fuckton of trees. It'll be a huge and expensive effort, whatever the solution is.
