First, you have to trust that scientists can measure the "Global Temperature." Then accurately determine what the temperature used to be tens, hundreds and thousands of years ago.

Second, you have to show that recent changes (as opposed to all the changes of the past) are due to burning of fossil fuels; not the hundred or so other factors that are simultaneously taking place.

Third, you have to prove that the man made changes will be harmful. Then, and only then can you come to the point:

MAY induce large-scale migration and lead to greater competition for the Earth's resources," and "there may be increased danger of violent conflicts and wars.

Why not give the prize to my third grader. He MAY grow up and be the bringer of Whirled Peas.
