Maybe not enough money to finish, but maybe enough to start... Build a starlink-style satellite fleet in a ring around the earth, facing the sun head on. Each satellite is basically a circular, large, thin-sheet mirror that pops open and unfolds from a coiled, folded, initially small packed size. The outer edge is a conductor that can carry current and induce a magnetic field that is used to rotate it against the earth's magnetic field. These can be used to focus sunlight on the pacific to generate cloud cover to tweak the earth's albedo at first. Later when there are more, say about enough to filter 2% of incoming solar radiation, they can be used for fine-grained tweaking to control incident solar radiation using the controlled shadow they cast combined with the occasional reflective heating of spots to tweak wind flows and large body of water temperatures. Coupled with climate modelling we use these to initiate a climate control programme which along with CO2 sequestration and some glacier geoengineering gives us our own climate as a garden. PS: Maybe a lot of them focused on a small area could melt rock, in which case one could maybe carve channels for water to tweak water availability in large inland areas to allow modification of moisture/rainfall patterns.
