In this lab, you will gather data about CO2 emissions using the National Oceanic and Atmospheric Administration Web site (Earth System Research Laboratory, n.d.) to help you write up a scientific report centered around known phenomena of CO2 emissions, related to the following question:
- Would you expect to see an increase or decrease in CO2 emissions in the data over the past 40 years? Why?
The natural balance that occurs between global atmospheric cooling and warming processes provides an important contribution to the Earth’s varied climates.
Planetary albedo from clouds low in the troposphere, sulfur dioxide (SO2) from active volcanoes, snow, and ice all reflect incoming solar radiation back into space. This causes a cooling effect on climates within a geographical area.
Clouds high in the troposphere and greenhouse gases such as water vapor(H2O), carbon dioxide (CO2) , methane (CH4) , and nitrous oxide (N2O) have a warming effect.
Along with the solar activity, these cooling and warming processes help ensure that the planet’s average surface temperature is a net value that is above freezing, helping to ensure that life is possible.
Theory on CO2 Emissions
It has been hypothesized that anthropogenic effects (conditions caused by human activity) that are associated with industry, agriculture, and fossil fuel use have enhanced these warming processes by contributing greenhouse gases such as N2O, CH4,and CO2 into the troposphere. As a result, CO2 is believed to contribute the most to the atmospheric warming process.
Pollution is a substance that produces a detrimental change in the environment because of its composition and abundance. Anthropogenic sources of CO2 fit this description because of the perception that there is evidence of a positive correlation between the increases in anthropogenic CO2 and increases in temperature. In turn, as temperatures increase, climates can change worldwide, unbalancing ecosystems across the globe.
Strategies and prediction models can be used to decrease or eliminate the effects that are associated with a particular pollutant. First, the cause of the pollution must be identified. Then, scientists can create innovate ways to reduce or eliminate its production.
