There is a correlation between co2 levels, temps and SLR, 360 feet from full ice age to hot house earth. How is building lots of cars going to undo what we have done, over 90 % of which has been absorbed by the oceans. Carbon capture? Leaving aside the problems with performing that at scale, it generally relates to future emissions not dragging all our historic emissions from the oceans. Our coastal cities will be gone.
