Global Warming and Ozone Layer by Brindha

Today I learned about Global Warming. Global Warming happens when the global temperature increases. It causes increase in the sea water. The Ozone Layer protects the Earth from dangerous ultra-violet radiation of the sun. However, it is destroyed If countries don't stop polluting, after 100 years all the ice in the North Pole will melt. The Climate Change is due to human activities. China and America are the world's two biggest emitters of carbon dioxide.

The North Pole is melting for the first time in 55 million years. The meltdown could also counteract the gulf stream.
