Since we are failing to curb global carbon emissions at all, we are left with using our huge brains, which got us into this problem in the first place, to try to wangle our way out of it.
Whether that’s solar engineering [sending back a small fraction of sunlight] or cloud seeding to reduce incident solar radiation, or reforestation, or carbon capture and sequestration from burning fossil fuels, or ocean iron fertilization or putting huge mirrors in space, humans think we can engineer our way around any issue. The best most direct strategy, that has the least bad side-effects, is to remove carbon directly from the atmosphere and make something useful out of it – like fuel – that would further lessen the burden on the environment.
One company is already doing that.
Based in Canada, Carbon Engineering’s Direct Air Capture system directly removes CO2 from the atmosphere, purifies it, and produces a pipeline-ready compressed CO2 liquid using only energy and water. This CO2 can be combined with non-fossil fuel-generated hydrogen, to produce ultra-low carbon intensity hydrocarbon fuels such as gasoline, diesel, and Jet Fuel-A.
