The natural greenhouse effect
The ozone layer
Global warming
Methane is a greenhouse gas with a global warming potential (GWP) 25 times greater than carbon dioxide. Which of the following is not a source of atmospheric methane that contributes to the enhanced greenhouse effect?
The use of aerosols and detergents
Decomposing garbage in landfills
Cattle, and other livestock, digesting food and releasing gases

Ozone, O3, is a gas found predominantly in Earth's stratosphere. Chlorofluorocarbons (CFCs) are compounds composed of chlorine, fluorine and carbon. Which of the following statements is false?
Ozone and CFCs contribute to the natural greenhouse effect
Ozone in the stratosphere blocks harmful UV rays emitted from the sun
CFCs break apart ozone molecules and deplete the protective ozone layer
Both ozone molecules and CFCs contribute to the enhanced greenhouse effect in the troposphere
Which of the following is the fundamental difference between the terms global warming and climate change?
Global warming measures the average temperature change of the whole planet, while climate change refers to the long-term weather of one region
Global warming refers to the long-term weather of one region, while climate change measures the average temperature change of the whole planet
Global warming measures the average temperature change of one region, while climate change refers to the long-term weather of the whole planet
Global warming compares the weather conditions of the whole planet, while climate change refers to the long-term temperature changes of one region
Nitrous oxide (N2O) has a GWP almost 300 times greater than CO2. What is the primary human source of N2O emissions?
The use of chemical fertilizers, and the improper disposal of waste
Natural bacteria decomposing organic material in the soil
The combustion of fossil fuels
Air conditioners
Which of the following statements about global warming is true?
Global warming has occurred many times in the past, but appears to be occurring more rapidly now than before
Most scientists agree that global warming will not have any effect on climate change for at least 100 years
During the last ice age in North America 21 000 years ago, average global temperatures were 12 ° C cooler than current average temperatures
All scientists are in agreement that global warming is occurring, and that human activities are responsible for the increased average global temperatures
Which of the following statements about albedo is true?
If the amount of snow and ice in the arctic decrease, the albedo of the area will decrease, and much more solar energy will be absorbed
If the amount of snow and ice in the arctic decrease, the albedo of the area will increase, and much more solar energy will be absorbed
If the amount of snow and ice in the arctic decrease, the albedo of the area will decrease, and much more solar energy will be reflected
If the amount of snow and ice in the arctic increase, the albedo of the area will decrease, and much more solar energy will be reflected
