What does a1 gore, author of an inconvenient truth, demonstrate about the levels of atmospheric carbon dioxide levels a. each year, the co2 level rises and then falls. over the past 50 years, it has steadily increased. b. each year. co2 level increases at a faster rate. over the past 50 years, it has nearly doubled. c. each year, it the co2 level decreases. over the past 50 years, it has steadily decreased.

The correct option is B:

Each year.CO2 level increases at a faster rate. Over the past 50 years, it has nearly doubled.

In "An inconvenient truth", A1 Gore illustrates clearly how the levels of CO2 has been increasing rapidly in the atmosphere since 1958, and proves that the increasing of the carbon dioxide emissions are a result of human actions. He explains this theory by presenting the Keeling curve, which shows that the last 14 years were the hottest ever recorded in the atmosphere, as well as other important studies proving the correlation between global warming and hurricanes.
