Mark Maslin is Professor of Climatology at University College London and co-author of countless scientific papers, popular articles and books. His areas of scientific expertise include causes of past and future global climate change and its effects on the global carbon cycle, biodiversity, rainforests and human evolution. In this talk, based around his Oxford University Press book "Climate Change: A Very Short Introduction", Maslin provides a compelling introduction into the complex field of climate change for a non-scientific audience. What are its effects, how do we measure them, and how can we predict its development in the coming decades? Limiting warming to no more than two degrees celsius has become the de facto target for global climate policy, so one questions that scientists have to answer is: What changes do policymakers have to implement, and which technologies do we need to develop, that we have the chance to meet this target?
