In Climate Change: The Facts 2020 scientists, economists and other experts critique current climate science and the failings of key national and global climate organisations while advancing our understanding of climate change. Richard Lindzen, Geoffrey Duffy, Hendrik Svensmark and Peter Ridd focus on the physics of climate and the role of water vapour in the atmosphere. Their contributions point the way to a new, more coherent theory of climate. In key chapters the cost of failed climate programs is explained, and institutional reforms and policy making truly based on evidence are advocated. In a vital section on the biology, geology and temperature records of the north and south poles, Donna Laframboise, Susan Crockford, Howard Brady and Roy Spencer challenge the common narrative of runaway warming and stressed ecosystems.
