Global Warming

Global warming is the rise in temperature of the Earth’s atmosphere. The earth is naturally warmed by rays from the sun which pass through the atmosphere and are reflected back out to space again.  The atmosphere’s made up of layers of gases – some of which are called greenhouse gases.  They’re mostly natural and make up a kind of thermal blanket over the Earth.
