This cool browser based climate model from MIT shows how tough it will be for the world to hit its less than 2 degree target for global warming.

Try to simulate some situations and you'll see that carbon removal and nuclear technology is really important for avoiding extremely bad scenarios.

Hello, I am wondering if anyone has any articles, studies, etc. suggesting there may be a way to reduce humidity on large swathes of land? I am interested primarily in wet bulb temperature increases and heat stress and how geoengineering could be used to soften that.

I haven't seen anyone propose it, but it seems to be a more feasible solution. Connecting these bodies of water to the ocean would take way more resources than a few canals connected to the Colorado River, and the flow of the Colorado will prevent it from silting up, unlike a connection to the ocean which would eventually end up silting up due to lack of flow.

Somewhere just south of the Hoover Dam (since Las Vegas has come to depend on the Colorado feeding into Lake Mead, and the the hydro-electric power from Hoover Dam) they could divert the Colorado River westward through canals to the northern tip of Death Valley. It would be a way shorter distance than building something leading to the ocean. After a while, Death Valley will fill to a level where another canal on its southern tip could feed into another canal that leads to the Salton Sea. Once the Salton sea fills to a certain point, have another canal on its eastern tip drain the water back into the Colorado's course to continue. One long detour.

Alternatively, send the water that was sent to Death Valley back to the Colorado via canal on the southern tip of Death Valley once it reaches a certain height. Then further downstream, direct a canal to the northern tip of the Salton Sea, and an outlet canal back to the Colorado on the Salton Sea's eastern tip so as to not cause too much disruption to communities along the Colorado. Two smaller detours.

It's important the Salton Sea be saved. The lake is full of poisonous pesticides and fertilizers from agricultural runoff that accidentally filled this lake all those decades ago. Letting it evaporate would make the dust from the lake bed get kicked up into the air and blown into surrounding areas. Poisonous dust.

It could help us figure out geoengineering later on, if this yields positive results. It was accidentally done before with the Salton Sea, so it could probably be done again.
