Just a silly joke of course. Gallows humor. In order to combat climate change you’d have to re-design how we live and work and our economic system and reset existing wealth inequalities, re-design and rebuild thousands of industrial processes, and change multiple systems that are in place. For example you’d at least have to:

1. Ban advertising to reduce desire/demand for consumption
2. Ban patents (at least in the current form) so industrial processes can be re-designed and rebuild without roadblocks
3. Nationalize news and social media and turn them into a cooperative under the control of the workers there
4. Invest into R&D for circular economy and development and regulation for long lasting appliances and goods that last decades with repair and maintenance

Basically what we learned is that it’s practically impossible for humanity as a global civilization to stop climate change. Most people can’t even bear to think about the steps it would take.

Of course, developing the technology for a sustainable circular economy for the basic needs (food, energy, education, building shelters, communication etc) is still worthwhile.
