The United Nation’s body on climate change, the IPCC, unveiled its fifth report on climate change in Stockholm this morning. The report provides further evidence that mankind is behind the world’s climate change.

Scientists believe that if the emission of greenhouse gases and carbon dioxide remains unchanged the world will see the average temperature rise between 2.6 to 4.8 degrees Celsius before the year 2100.

The report also presents four different scenarios for the rising average temperature, based on what actions are taken to halt the emission of greenhouse gases and carbon dioxide. The most optimistic of the four scenarios shows that the average temperature will increase by 0.3 to 1.7 degrees celsius, if the emission of greenhouse gases and carbon dioxide is reduced immediately.

During the still ongoing press conference Rajendra Kumar Pachauri, head of the IPCC, says that the only way of lowering the emission of carbon dioxide is to introduce global carbon pricing.
