Professor Chris Jackson charts the planet's changing climate. He shows how the oldest rocks and fossils provide evidence of radical climate changes throughout its history, revealing that what drives them is the amount of carbon dioxide in the atmosphere.
Dr Helen Czerski reveals how shifting ocean water distributes heat and nutrients around the Earth. This process is linked to almost every aspect of human existence, and the lecture explores how dependent we are on the ocean for weather, food supply and connection between land masses - as well as exploring what needs to be done by humans to maintain this vital element of the Earth's ecosystem.

It’s a common saying that elephants never forget. But the more we learn about elephants, the more it appears that their impressive memory is only one aspect of an incredible intelligence that makes them some of the most social, creative, and benevolent creatures on Earth.
Last century, earthquakes killed over one million, and it is predicted that this century might see ten times as many deaths. Yet when an earthquake strikes, it always takes people by surprise. So why hasn't science worked out how to predict when and where the next big quake is going to happen? This is the story of the men and women who chase earthquakes and try to understand this mysterious force of nature. Journeying to China's Sichuan Province, which still lies devastated by the earthquake that struck in May 2008, as well as the notorious San Andreas Fault in California, Horizon asks why science has so far fallen short of answering this fundamental question.
