0 views

The top 3 greenhouse gases contributing to climate change are: 1. Carbon dioxide (CO2), primarily from burning fossil fuels and deforestation. 2. Methane (CH4), emitted during the production and transport of coal, oil, and natural gas, as well as from livestock and other agricultural practices. 3. Nitrous oxide (N2O), from agricultural and industrial activities, as well as combustion of fossil fuels and solid waste.

FAQs & Answers

  1. What are greenhouse gases? Greenhouse gases are atmospheric gases that trap heat, contributing to the greenhouse effect and global warming.
  2. Why are carbon dioxide, methane, and nitrous oxide the most concerning greenhouse gases? These gases are the most prevalent contributors to human-caused global warming due to their volume of emissions and heat-trapping capabilities.
  3. What are the main sources of methane emissions? Methane emissions mainly come from production and transport of fossil fuels like coal, oil, natural gas, as well as livestock and agricultural practices.
