I’m not denying that it’s bad, I know it’s bad and a horrible thing, but I wanna know how changes that are only 1.5° affect it so much and matter so much.

1.5 is the average. In some areas it will get hotter, in other colder.
One of the big problems is that one of the areas it’s going to get hotter is the tundra. Tundra stores a lot of methane. When it melts the methane will be released. Methane is also a greenhouse gas and so this will increase warming even more.
Some places that will get colder will be food producing areas that won’t be able to produce as much food anymore.
The other is that warming increases evaporation of water. Water vapor is also a greenhouse gas.
So the more warming there is the more greenhouses gases are released into the atmosphere and the more warming that takes place. At some point it will run away and continue no matter what we do.
