A blog called “DeSmogBlog” has a pretty good run-down of the Democrats’ “town hall meeting” on climate change. I have to admit, I have not watched the whole thing, or very much at all.

Here’s my take. First, there are short- to medium-term practical issues that need to be tackled immediately and simultaneously. The first is disaster preparedness and disaster response – storms, fires, floods, droughts. We need to be ready for a major earthquake, plague or terrorist attack too although we can’t blame the climate directly for these. The second is the long-term stability of the food system under projected temperature and water supply trends. The third is dealing with the systemic corruption that has allowed the fossil fuel industry to buy and control our politicians for decades.

I think Bernie Sanders and Elizabeth Warren understand these issues best. I don’t think other candidates understand them at all. I think they divorce them from larger socioeconomic issues to a certain extent, and that is a mistake. It should be possible to take advantage of fluctuations in the economy, employment, and financial system to make the right investments at the right time and minimize the pain.

Beyond these, we need to deal with our interwined land use, energy, transportation, food, and ecosystem issues. It could be done in ways that would be a win for everyone. Invest in the right kinds of infrastructure, education and training for workers, and innovation. It is unlikely to be done because our education system does not provide the public with the mental tools needed to understand systems, and therefore we do not elect politicians who understand systems and have workable ideas on how to fix them. This will still be true even if the corruption issues can somehow be solved.
