If you would predict the future, what would happen on earth in the future?

Question

I just wanted to know what would happen to earth in the future, so I get answers and I compromise them then I believe that would happen. I wanted to be a special scientist when I grow up and I have many ways to help save planet earth.But it's not like your a fortune teller or something. Fortune teller s are not true. Scientists predict that earth will turn a little like into an oval. How did they do that? They get so many answers. So can somebody answer my question please?

Answer 1

I'd say the world will continue and change as it has always.  It has had periods of great heat like during the dinosours and great cold like the last ice age, all without man doing a thing.  Life will continue on earth in some form until the sun expands into a red giant in a few billion years and cooks earth to a cinder, then it will be lifeless

Answer 2

well the way things are going world war 3 will happen and everybody will use nucleur weapons and the world end.
