Global warming is a real threat to our planet. Global warming is caused by CFCs build up in the atmosphere and the ozone layer cannot hold them and they break through. CFCs can be any form of pollution such as cars and exhaust from anything even light bulbs!! This thins the layer of the ozone especially at the poles. The sun shines through more strongly and is melting the ice at the poles therefore sea level is rising and causing more natural disasters because of it.
Global Warming is also causing natural disasters like tsunamis, cyclones, floods and droughts . In the last 100 years the sea level has risen 59cm.Sea levels will continue to rise unless we cut down on pollution. There are more effects by global warming. Please watch this video to see what we mean.
