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.
