What are the main greenhouse gases? Carbon dioxide (CO2) CO2is released through natural processes, such as volcanic eruptions, plant respiration and animals and humans breathing. Butthe atmospheric CO2concentration has increased by 50%since the Industrial Revolution began in the 1800s, due to human...
What are greenhouse gas emissions? The release of certain gases into the Earth’s atmosphere can create a “greenhouse effect”, in which heat becomes trapped and global temperatures rise. While emissions can result from natural causes, they are primarily the result of human activities, especially...
