What does al gore, author of An Inconvenient Truth, demonstrate about the level 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, the CO2 level increases at a faster rate. Over the past 50 years, it has nearly doubled
c. Each year, the CO2 level decreases. Over the past 50 years, it has steadily decreased

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

According to An Inconvenient Truth, what is the role of infrared radiation in global warming?

a. All of the sun's energy is converted into infrared radiation and then remains in the atmosphere. This warms the atmosphere.
b. Over time, infrared radiation makes the atmosphere thinner. This warms the atmosphere.
c. Greenhouse gasses trap some infrared radiation in the atmosphere. This warms the atmosphere.

c. Greenhouse gases trap some infrared radiation in the atmosphere. This warms the atmosphere.

In which sentence below is the word in * an indirect object?

a. Gore published *An Inconvenient Truth* a few years after he ran for president
b. My sister gave *me* a signed copy of the book
c. She said she preferred the documentary *film*.

b. My sister gave *me* a signed copy of the book.

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

To find the answer to this question, we can refer to Al Gore's work in "An Inconvenient Truth," which is a documentary film about climate change. In the film, Al Gore demonstrates the level of atmospheric carbon dioxide (CO2) levels by providing scientific evidence and data.

The correct answer to the question is:

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

Al Gore presents data in his documentary showing that the level of atmospheric CO2 has been steadily increasing over the past 50 years. He highlights that the rate of increase has been accelerating, meaning that each year, the CO2 level grows at a faster rate than the previous year. This trend has led to a nearly doubling of CO2 levels over the given time period.

To fully understand the impact of Al Gore's work on atmospheric CO2 levels, I encourage you to watch or read "An Inconvenient Truth" or explore the scientific research on climate change. This will provide you with a more comprehensive understanding of the topic.
