Climate Change

The earth’s climate varies naturally, but scientists now have strong evidence that the relatively big, long-lasting changes in climate we are experiencing are likely to be the result of human behaviour.

Greenhouse gases have a vital role in keeping the planet warm enough to support life. They allow the sun’s rays through but stop some of the heat from escaping back into outer space.

However, a lot of greenhouse gases, such as water vapour, carbon dioxide and methane are now produced through human activity. These extra greenhouse gases trap more of the sun’s heat and cause the temperature to rise.

A rising carbon dioxide (CO2) level is a particular problem because it has a long lifespan. Humans upset the natural carbon cycle by emitting CO2 through the burning of fossil fuels and the destruction of habitats.
