Question

If the greenhouse effect causes the average temperatures of Earth to increase by 3 degrees fahrenheit between the years 2020 and 2050, what is the rate of temperature change?

Answer 1

0.1 degree per annum

Step-by-step explanation:

There are 30 years between the years 2020 and 2050. If the average temperatures increase by 3 degrees Fahrenheit in 30 years, then the rate of change of temperature equals the ratio of the total increase in temperature and the number of years.

Rate of change = 3/30 = 0.1

Hence, the rate of temperature change is 0.1 degree Fahrenheit annually.
