Technology

Instead of treating the symptoms we must address the cause. The cause is CO2 emissions. The solution is to reduce these emissions. Keep the oil in ground as much as possible—we still need some for lubricants, solvents, polymers etc but honestly, burning oil is stupid since it can be used in much better ways. Although we must also reduce the use of single-use plastics, volatile organic compounds and "forever chemicals" as much as possible since these pose real environmental and health risks, too.

We have the technology to address the emissions—photovoltaics, wind, hydro and, yes, nuclear power; everyone can reduce or even stop meat consumption if they want; every city and country can build good public transport and walkable communities; every government can regulate harmful chemicals. The problem is societal inertia, NIMBY-ism, FUD plus outright conspiracy delusions and unwillingness to change from the powers-taht-be.
