Understanding anthropogenic climate change is essential for anyone working in the life sciences. Firstly because climate change has already started to impact the Earth biosphere and human health and these changes need to be documented and acknowledged. Secondly, many of the solutions to climate change, both mitigation and adaptation, will be through the life sciences, everything from massive reforestation and sustainable agriculture to preventing the spread of disease and protecting individual human health. Anthropogenic climate change is, therefore, one of the defining challenges of the 21st century, along with poverty alleviation, environmental degradation and global security. Climate change is no longer just a scientific concern but encompasses economics, sociology, geopolitics, national and local politics, law and health to name a few. Hence, to understand climate change fully then not only does one have to review the science but also the politics and geopolitics, which have created the issue and can provide the solutions. Climate change ultimately makes us examine the whole basis of modern society and ultimately asks questions about humanity's relationship with the rest of the planet.
