Current investment in solar geoengineering is roughly 10 million annually (this may have increased in the last few years), so by most metrics it’s really neglected. The main project working on this is the Harvard solar geoengineering research program, which OPP has funded about 2.5 million dollars for a few years in 2016. They’ve also funded a solar governance program in 2017 for about 2 million dollars. Grants here. Recently, they don’t appear to have made any climate-related grants in this space, and its unclear to me what the funding situation looks like.
Regarding states that have committed to doing things: I didn’t find anything on doing a shallow dive. However, there is work being done on it in a number of countries. In particular, scientists in India have raised concerns that current models show potential for drought and famine because of reduced water flow in tropical regions like India. (This is in addition to technical and general governance concerns)
