Match the following statements with the correct description of Earth's temperature trends based on geologic and current data.

• Temperature and CO2 levels have always fluctuated, but we are currently in a downward temperature trend

• Temperature and CO2 levels have always fluctuated, but we are currently in an upward temperature trend

• Temperature and CO2 levels have remained exactly the same until the Industrial Revolution, then increased

• Temperature and CO2 levels have remained exactly the same for the last 400,000 years

Ice samples from glaciers provide evidence that today’s atmosphere contains more carbon dioxide than ancient atmospheres did. This increase concerns scientists because

• increased carbon dioxide may cause plants to grow very rapidly

• this may cause a loss in the amount of energy reaching the Earth from the Sun

• this may contribute to a gradual warming of the atmosphere

• this may contribute to a rapid cooling of the oceans

The greenhouse effect

• makes life on Earth possible, because without it Earth would be too cold to live

• needs to be completely eliminated if humans are to continue to survive on planet Earth

• did not exist until humans began burning fossil fuels

• makes life on Earth possible, because without it Earth would be too hot to live

(choose all that apply!) The graph represents the average yearly concentration of carbon dioxide (CO₂) in Earth's atmosphere from 1972 to 1993. This change in CO₂ concentration most likely caused.

• a decrease in the average wavelength of radiation emitted by the Sun

• a decrease in Earth's evapotranspiration

• an increase in the absorption of heat by Earth's atmosphere

• an increase in the Thiness of Earth's glaciers

Two identical glass containers were placed in direct sunlight. The first container was filled with air and the second container was filled with a mixture of air and carbon dioxide. Each container was sealed with a thermometer inside. Temperatures were recorded at 2-minute intervals, as shown in the data table. Which statement best explains the results of this activity?

Groups:

(a) False

,

(b) True

• Air retains more heat than CO2+Air

• CO2 is a green house Gas

• Air+CO2 over time retains more heat than air alone.

• Air does not retain heat at all.

• Increased CO2 levels lead to higher global temperatures.
