THE TRUTH ABOUT CLIMATE CHANGE by Sir David Attenborough

The legendary broadcaster and naturalist Sir David Attenborough was long unsure about the causes of the observed climate warming. In his documentary, The Truth About Climate Change, he sheds doubt and explains what convinced him.

Climate models based on purely natural processes such as solar activity and volcanic eruptions fail to explain the observed change in Earth's climate in the latter part of the 20th century. Models factoring in the human impact, that is, the increase of carbon dioxide in the athmosphere, depict the transpired warming accurately, however.

They lie dormant for hundreds of thousands of years as a vast reservoir of magma builds up inside them before finally they unleash their apocalyptic force, capable of obliterating continents. They threaten the survival of mankind. What happened during the last eruption of a super volcano? The last eruption of a super volcano was in Toba, Sumatra, 75,000 years ago. It had 10,000 times the explosive force of Mount St. Helens and changed life on Earth forever. Thousands of cubic kilometres of ash was thrown into the atmosphere - so much that it blocked out light from the sun all over the world. 2,500 miles away 35 centimetres of ash coated the ground. Global temperatures plummeted by 21 degrees. The rain would have been so poisoned by the gasses that it would have turned bla...
