Why is no one considering tasking a global effort to develop a composite "mylar like" material and deploy an installation at L1? There's also the option of lunar manufactured materials using a magnetic catapult to deliver to L1. It would have to be a global effort because of the costs, but would be far easier to anticipate and correct issues vs an earth based solution that geoengineers the atmosphere. It's ambitious, sure, but would buy us a lunar base. L1 could me manned as needed or robotics.
