In 2013, a lot of people were shocked by a news photo of a dead polar bear that was found on Norways Arctic island of Svalbard. According to the scientists who found its dead body, all that remained of the polar bear was . The polar bears situation is extremely dangerous and the climate change does great harm to it.

Experts claimed that low sea-ice levels caused by climate change meant the bear could not hunt seals as before, so it had to travel greater distances in order to find food. This case showed how the increase in temperature had an impact on Earths ecology.The global warming is very severe and beyond our recognition. Climate scientists have warned that if we do not take appropriate actions, this warming trend will probably continue and there will be a higher price to pay . In fact, news reports are frequently broadcast about extreme rainstorms and heatwaves causing deaths and economic losses.Its high time to do something to slow and control climate change.
