It's never too late if you seriously consider all your options Ie:
Full nuclear energy development with SMRs
Fusion reactors research
Full transition to electric/hydrogen vehicles
Economic sanctions to countries with grid power coming from carbon/ non renewable resources above a certain percentage
Full development of lunar/cis lunar infrastructure/space
Large scale deployment of solar mirror arrays designed to reflect incoming sunlight, built using lunar regolith as raw materials source
Blowing an 88 megatons hydrogen bomb under the sea, below 8 to 12 Km under the ocean floor surface to trigger about 30 years of carbon capture in a second
The US is fucked anyway, but if China and the EU worked together, greatness could be approved on potentially the most important front:
Economic sanctions to countries with grid power coming from carbon/ non renewable resources above a certain percentage
However, the one I'm most curious about is the following:
Blowing an 88 megatons hydrogen bomb under the sea, below 8 to 12 Km under the ocean floor surface to trigger about 30 years of carbon capture in a second
How would this work? I'm really interested in the mechanics of this, not so much the feasibility (which is non-existent anyway)
I'm a pessimist in that even in the best possible situation humans would still find a way to overpopulate the earth until no solution is viable. We are parasites
