If humanity does not change course, then Earth could warm by roughly 6 degrees Fahrenheit by the end of the century.

I. An increase in the Earth's temperature by 6 degrees Fahrenheit can cause widespread plant and animal extinctions.

II. Deadly heat waves can cause widespread plant and animal extinctions.
