SOMEONE IS GOING TO DIM THE SUN, AND IT WILL BE SOON

Summary from the TLDR newsletter

Solar Radiation Management (SRM) is starting to gain more attention due to 2023's high temperatures. It's much easier to artificially dim the sun than most people imagine. Injecting sulfur into the stratosphere could be a cheap way to cool down the Earth. It would have an almost instant effect, but once it starts it would be dangerous to suddenly stop. SRM will not fix the root cause of the problem, but it could buy time for us to remove CO2 from the atmosphere. However, its implementation could make us more complacent about fixing the core issues.
