At some point, there will be a serious effort to put offshore wind on Lake Michigan. I fully expect to see idiots on Xhitter saying it's going to kill all the whales.
I'd like to see more pumped water reservoirs making use of the strip mining pits. Most of the damage and work is already done, might as well make the most of it.
This won't stop the Earth from getting hotter! It's barely a drop in the bucket.
Meanwhile, the billions spent on war will directly result in massive carbon emissions from jet fuel, tank fuel, bombs, and the energy spent building all that equipment and shipping it halfway across the world.
