What are Greenhouse Gases?
Greenhouse gases, sometimes written as ‘GHGs’, are gases (such as carbon dioxide and methane) that trap heat from the sun inside Earth’s atmosphere. As more greenhouse gases are released into our atmosphere (largely through the burning of fossil fuels), more heat is trapped by them. This raises the temperature of our air, oceans, and water, changing our living conditions and increasing the likelihood of extreme weather events both globally and locally.
