'Brilliant and fundamental, this is the necessary book about our prime global emergency' Ian McEwan The news is full of hotly debated and divergent claims about the impacts and risks of climate change. Lawrence Krauss, one of the world's most respected physicists and science popularizers, cuts through the confusion by succinctly presenting the underlying science of climate change. The Physics of Climate Change provides a clear, accurate and accessible perspective of climate science and the risks of global inaction. Krauss's narrative explores the history of how scientists progressed to our current understanding of the Earth's climate and its future. Its generous complement of informative diagrams and illustrations allows readers to assess which climate predictions are securely based on analysis of empirical data, and which are more speculative. The Physics of Climate Change is required reading for anyone interested in understanding humanity's role in the future of our planet.
