You've missed the point by 50 years or so!
We now have life impacted by excessive use of fossil fuel, which should have been wound down and stopped a long time ago. It's probably too late.
We have the replacements already - insulation and demand reduction first, wind power, solar, hydro, etc.
What we don't have is the political will or courage, let alone an intelligent agenda.
This is interesting.
Sea surface temperatures breaking records
Look at the graphs; even as recently as the 80s sea temp was high but steady. This year for the first time it is going off the chart. It may recover, it may not.
We now have rapidly melting Antarctica, which with Greenland etc could raise sea levels by 70 metres.
