Feasibility of cooling the Earth with a cloud of small spacecraft near the inner Lagrange point (L1) by Roger Angel

>For all 20 million launchings the capital cost would be ≈$600 billion and the electrical energy cost $150 billion

note this was written before spessx revolutionized the launch industry

Space sunshade might be feasible in global warming emergency
UNIVERSITY OF ARIZONA

>"The concept builds on existing technologies," Angel said. "It seems feasible that it could be developed and deployed in about 25 years at a cost of a few trillion dollars. With care, the solar shade should last about 50 years. So the average cost is about $100 billion a year, or about two-tenths of one percent of the global domestic product."

to put that into perspective the war in afghanistan cost 2.4 trillion and just created more terrorists (but maybe heroin cheaper which is unironically awesome)
