The chip situation dates back to the 80's and 90's. It stems from two things.

1. It takes MASSIVE amounts of clean water to make chips. REALLY MASSIVE amounts of water. That's a problem in a lot of places.

Not Taiwan. Taiwan is phenomenally rainy. Taiwan doesn't typically have a water problem. Although there is currently a drought.

2. All of the clean water used in the manufacturing process gets contaminated with nasty cancer causing chemicals. That was a big problem in the US.

A bunch of early chip makers like Fairchild went under because of lawsuits related to ground water contamination. Chip making is a dirty industry although it doesn't look like it.

Taiwan wanted the industry, has loads of clean rainwater, doesn't regulate the chemicals, and has the Pacific Ocean to use as a waste dump.

Now do you see why Taiwan is the chip making center of the world?

As far as the solar system warming up, that could only happen if the sun is heating up. It could be a little bit, it has cycles. But overall, right now we are in a cooling cycle orbitals. Without GHG influence the planet would be slowly getting colder.
