The solution to climate change is very cheap and simple. It is a carbon tax. It is also not difficult to implement at all and will cause only modest inflation.
However, the oil industry is a huge influence on governments all over the world and will throw everything at preventing this from happening.
Imagine for a moment that all of the carbon taxes were directed to subsidize EV and solar. All if us would be driving cheap EVs and getting 90% of our electricity from solar sources.
