What is one outcome of using fossil fuels as an energy source?

Using fossil fuels as an energy source substantially increases the concentration of greenhouse gases in the atmosphere, primarily carbon dioxide (CO2) and methane (CH4). When fossil fuels, such as coal, oil, and natural gas, are burned for energy production, they release these gases as byproducts of combustion. The increased levels of greenhouse gases are a major contributor to climate change, as they trap heat in the Earth's atmosphere, leading to global warming.

This outcome is significant in environmental science as it directly relates to the challenges of climate change and the pressing need to transition to alternative energy sources that produce lower emissions. Understanding this relationship emphasizes the importance of developing sustainable energy solutions that minimize greenhouse gas emissions and mitigate their impact on our climate and environment.
