Question

can the suns gravitational pull on the earth affect the temperature as the gravitational pull could suck us in like a black hole does after many of millions of years.could this be a reason for climate change increase.

Answer 1

A black hole doesn't suck things in any harder than any other object does, unless you're closer to it. The Earth hasn't gotten any closer to the sun in many years. This is not the reason for climate change.
