Prevent ocean acidification killing all plankton, leading to mass extinctions? Capture CO2 or carbonic acid, permanently? Molten Salt Reactors can provide the power.
Molten Salt Reactors to drastically reduce CO2 emissions, to protect the many cities where sea level rise doesn’t already mean frequent flooding within a few years.
MSRs can’t have loss of coolant accidents, can’t have high-pressure explosions, produce no CO2, use uranium or thorium as fuel, eliminate long-term nuclear waste, are cleaner & cost less than coal or oil.
