Why hasn’t the earth completely cooled since it was formed so long ago? BRAINLIEST FOR FIRST ANSWER! MUST BE ACTUAL ANSWER!

It is cooling, but this process is very slow: the inner core only grows about one millimetre a year, because the Earth has a rocky mantle in between its hot core and its cold surface, which stops it from cooling down too quickly – just like a jacket keeps you warm in the cold.

i hope that helped :D

it is very hard for the climatologists to precisely predict how will the global temperatures be changing so there's lots of models, some of which differ significantly, this is due to multiple factors, and probably the most important is the human activity.

humans have been a key factor in climate change around the globe since the start of the industrial revolution, and in the past few decades the consequences are becoming more obvious. there's lots of emission of pollutants in the atmosphere as well as changing the environment on the surface itself, so it's really hard to predict how will that go in the future because there's some countries that are reducing the damage and are going towards green energy, while others are stubbornly continuing with pollution and damages to the environment.
