The potential environmental impact of loads of silver iodide on human and other animal life is of concern. But it is China, so they probably don't care about that aspect.

Not only China, but which large country cares about larger environmental impact? Looking at the weapons the big countries are still building (man made floods, tornadoes etc) I don't think it's fair to target China alone.

Excluding systems which put water into the air, Atmospheric water is a zero sum game AFAIK so if this causes rain to fall where the Chinese want it, somebody else misses out.

Freshwater from high mountains in the India/China region is a hot topic. They're running out of glaciers.

It's possible, even likely, that much of the rain would have fallen on the ocean.

Really? Because most of the moisture originated from the oceans in the first place. Are you saying that after genesis, it travels for some time over land before being deposited back in an ocean?

provided no other variables... considering it's 71% of the area of the planet, I'd say it's 71% likely to rain on the ocean

Agree. It would work out if the rain was destined for the ocean or other unusable area. Otherwise they are taking it from other people.

In other news, in San Francisco, the NIMBYs won an agitation to prevent a 4 school building from being constructed.

I am kidding..maybe.

In all honestly, I think the time for US to create large scale construction projects that serve humanity (at the expense of environment) are over. We are lucky that the interstates got build in 1950s, that the NYC Subway was formed in late 19th century etc. Today, the regulations and outrage is so strong that none of these would have been possible.

It is good to see other countries such as China being on the cutting edge to see what is possible.

I don’t think so. I’m not an expert but I know that mountains contribute to the cloud formation and also the temperatures gradient between the land and the sea may contribute. So I would think that you can’t just take the percentage of land mass to predict the percentage of precipitations.

I wonder how much of it is equivalent to depriving the Pacific Ocean of rainfall, and whether that has meaningful implications.

MIT figured out fusion this month, water shortages are on the verge of being solved since water is not scarce, just dirty/salty - it's an energy problem.

I think the recent 200GW solar power deal between Saudi Arabia and SoftBank has more potential to solve desalination problems than Fusion (at least over the medium term).

It worth to mention that the southern part of China has a different climate than the north. It is very normal that during summer, there is flood in South but drought in North. The situation may different from year to year but the trend is very clear. That is also why there is South–North Water Transfer Project[1]
