Climate change or global warming is caused by carbon dioxide and other polluting gases. The UK with 1% of the world's population produces 2.3% of the world's carbon dioxide.
Greenhouse gases are released by burning fossil fuels - coal, oil and gas.
Heat from the sun is trapped by the gases in our atmosphere, forming a blanket around the earth - like the glass of a greenhouse.
Your carbon footprint
Greenhouse gases absorb and re-emit some of the infrared radiation that would normally be radiated out into space. Some of the re-emitted radiation is re-absorbed by the earth's surface, warming it.
