Heat from the sunshines onto the Earth. It passes through a blanket of gases in our atmosphere.
Some of the heatenergy is reflectedback into space. Some of the heat energy gets absorbed by the blanket of gases.
The ‘greenhouse’ gases areessential to life on Earth. Withoutthem heat energy would escapeback into space. Earth would be a very chilly place with an average temperature of -18°C !
The greenhouse gases help to keepthe temperature of the earth inbalance. This process is called theGREENHOUSE EFFECT. The gases work a bit like glass in a greenhouse to trap in warmth. But the earth is getting warmer and warmer. WHY?
Human activities are creatingmore greenhouse gasesincluding carbon dioxide, CO2. As we burn more fossil fuels, for example, the blanket of greenhouse gases becomes thicker.
More greenhouse gases in theatmosphere mean that moreheat energy is absorbed. We call this increase in the temperature of the earth ‘global warming’.
Eleven of the last twelve years have been the hottest since records started in 1858.Think about ways that you could reduceyour carbon footprint and be part of the climate-change solution!
