Anne McElvoy looks back at the life of the maverick scientist James Lovelock who pioneered the theory of Gaia, of a self-regulating Earth. Lovelock also looks to the future and the next evolution of Gaia which could lead to the extinction of human life, and a rise of Artificial Intelligence, but the writer and ecologist George Monbiot prefers his future world with wolves, wild boars and beavers living alongside humans. The UN's intergovernmental panel on climate change has warned to expect more volatile weather patterns, and the physicist Joanna Haigh explains how scientists from all disciplines are working together to measure the impact of solar activity on the Earth's climate.
