I have written a book 'Ocean Acidity Climate Shock' where at 493 ppm CO2 concentration level the Ocean pH will suddenly become more acidic,  along with temperature changes, this would probably kill the phytoplankton and algae and other ocean plants,  causing the loss of half the world's oxygen (O2) supply, and killing the base of the food chain in the ocean, causing the loss of the fisheries, and a lot more.
70% of the CO2 rise is caused approximately by coal, natural gas and oil power plants worldwide.  If a SynGas power plant was paired with each hydrocarbon power plant,  it could work synergetically with it to capture all its CO2, and turn that gas into carbon monoxide (CO) catalytically and it could be mixed with hydrogen (H2) from electrolysis of water (H2O) creating SynGas fuel that can be burned in gas turbines just like natural gas to generate electricity.  Cryogenics can be used to separate the nitrous oxides, CO2 and H2O cheaply.  Together, the hydrocarbon plant would supply enough power to bootstrap the Syngas plant and once working, it should tick over nicely.  Careful design of the symbiosis is required but possible.  Syngas is being used on the MIR space station to generate oxygen, water, electricity and remove CO2 from the capsule atmosphere.
The first SynGas power plant could be designed and built for 50-60 million poinds. The marginal cost of subsequent plants would cost 5-10 million poinds approximately. the same cost as a natural gas power plant and deliver approximately the same power as one.  Propane tanks would be needed to store syngas fuel.
This approach could worldwide, stop CO2 increases dead in their tracks, and be economically viable and provide jobs for a long time.  We have about 10-20 years to accomplish this task before time runs out.  Covid has temporarily caused a cessation of Daily CO2 (check this website) increases but barely due to the lack of car and truck travel under the pandemic.  This is a temporary hiatus, and is likely to be over once the virus has been stopped worldwide then the increases in CO2 will come back. 
Hooray for Joe and Kamala,  the Paris Climate Change Accord is going to be observed in America again as of today!
