What is a significant environmental impact of burning fossil fuels?

Burning fossil fuels is a significant environmental concern primarily because it releases excessive carbon dioxide (CO2) and other greenhouse gases into the atmosphere. When fossil fuels such as coal, oil, and natural gas are combusted for energy, they undergo a chemical reaction that releases energy but also generates CO2 as a byproduct.

The accumulation of CO2 in the atmosphere contributes to the greenhouse effect, leading to global warming and climate change. This increased concentration of carbon dioxide traps heat in the atmosphere, resulting in altered weather patterns, rising sea levels, and negative impacts on ecosystems and biodiversity. The connection between carbon emissions from fossil fuel combustion and climate change has been well-documented, making this a critical area of concern for environmental scientists and policymakers alike.
