As mechanisms to help reduce net emissions go, planting trees is probably the one likely to encounter the least resistance, so I'm all for it, but the idea that it's going to help us avoid far more painful changes seems a little foolhardy.
If we start doing it at scale, a lot of people will assume it will work and think it's okay to make cross country trips in a big RV.

I'm all for people making cross country trips in a big RV, providing they're properly paying for whatever long-term environmental costs are involved - folks aren't going to get behind a plan to save the planet if they never get to spend any time enjoying it.
