Identify and analyze the way fossil fuel combustion has changed the composition of Earth's atmosphere, and the way this change has affected climate.
(4 points)
Fossil fuel combustion has significantly altered the composition of Earth's atmosphere by releasing large amounts of greenhouse gases, particularly carbon dioxide (CO2), methane (CH4), and nitrous oxide (N2O). These gases trap heat in the atmosphere, leading to an increase in global temperatures, known as global warming.
The increase in greenhouse gases from fossil fuel combustion has led to the enhanced greenhouse effect, causing the Earth's climate to change rapidly. The increased concentration of CO2 in the atmosphere has led to higher temperatures, melting polar ice caps, rising sea levels, and more frequent and severe extreme weather events such as hurricanes, droughts, and heatwaves.
Additionally, the combustion of fossil fuels also releases pollutants such as sulfur dioxide and nitrogen oxides, which can contribute to air pollution, acid rain, and respiratory illnesses.
Overall, the combustion of fossil fuels has had a profound impact on Earth's atmosphere and climate, leading to significant environmental changes and challenges for ecosystems and human societies around the world.
