the rubber in the heating is degenerating because of wear.... only fix is to replace the rubber
We call them sunspots, but dark and cool are relative terms. A sunspot is dark only relative to the surrounding solar surface, but still intensely bright compared to your common household light bulb. It's cooler than the surrounding solar material, but still hot enough to vaporize a spaceship and anyone inside it in a fraction of a second.

The black spots on the sun are called sunspots. These cooler areas on the sun's surface appear darker than their surroundings due to intense magnetic activity inhibiting heat flow. Sunspots can vary in size and number over an 11-year cycle known as the solar cycle.
That depends on what the black spots are.

They don't. Climate change occurs on the Earth. Sun spots and solar flares occur on the Sun. The Sun heating up could cause a climate change on the Earth, but sunspots and solar flares don't really have much to do with that.

Cheetah spots are typically black on a golden yellow to tawny fur background. The spots help the cheetah camouflage in its natural habitat, allowing it to blend in with the grasslands and bushes where it hunts. The unique pattern of spots on each cheetah is like a fingerprint, with no two cheetahs having the exact same spot pattern.
