    50 years ... 2.5 degrees

    1 year ... x degrees = ?

    If you would like to know what is the rate of change in worldwide temperatures per year, you can calculate this using the following steps:

    50 * x = 2.5 * 1

    50 * x = 2.5 / 50

    x = 2.5 / 50

    x = 0.05 degrees per year

    Result: The rate of change is 0.05 degrees per year.
