Global Warming Repeat Exercise 91 using the United Nations “midrange scenario” prediction:
where t is time in years since 1750.
Exercise 91:
Global Warming The most abundant greenhouse gas is carbon dioxide. According to a United Nations “worst-case scenario” prediction, the amount of carbon dioxide in the atmosphere (in parts of volume per million) can be approximated by
where t is time in years since 1750.
a. Use the model to estimate the amount of carbon dioxide in the atmosphere in 1950, 2000, 2050, and 2100.
b. According to the model, when, to the nearest decade, will the level surpass 700 parts per million?
