Greenhouse gases heat up our planet. They are part of
Earth’s atmosphere and trap warmth emitted by the sun, thus heating Earth. It
is this process – the greenhouse effect – that makes life on the planet
possible.
Natural greenhouse gases like carbon dioxide, methane
and nitrous oxide have always been in the atmosphere. Without them, the world’s
average surface temperature would be a chilly – 18 degrees Celsius. However, we
enjoy an average temperature of 14 degrees.
