Climate change and what to do about it.

This is your regular reminder of the actions that should be taken by people who believe that climate change is a serious problem:

1. Immediately begin building as many nuclear power plants as possible and invest heavily in next-generation nuclear and geothermal power research.
2. Research and create plants that are genetically modified to be drought and heat resistant.
3. Build lots of dikes to protect infrastructure and people from rising sea levels.
4. Make cities resistant to flooding by improving drainage systems, building flood barriers, and equipping buildings with backflow prevention devices and watertight doors.
5. Prevent wildfires by clearing underbrush and building camera masts that rise above the treetops, automatically detecting smoke and alerting local fire departments so that any fire can be smothered before it gets out of control.
6. Build and subsidize air conditioning in buildings to protect the elderly and vulnerable.

And here is what people should also do if they believe that climate change is an existential risk:

1. Research and then mass produce portable air conditioning.
2. Invest heavily in geoengineering research.
3. Massively invest in research into how to cheaply build large numbers of [underground] vertical farms [powered by geothermal energy] and genetically engineered crops optimized for such an environment.

Very little of the above is advocated by people who claim to believe that climate change could endanger human civilization. Ask yourself why this is so.
