Ours is the age of global warming. Rising sea levels, extreme weather, forest fires. Dire warnings are everywhere, so why has it taken so long for the crisis to be recognised? Here, for the first time, climate scientist Peter Stott reveals the bitter fight to get international recognition for what, among scientists, has been known for decades: human activity causes climate change. Across continents and against the efforts of sceptical governments, prominent climate change deniers and shadowy lobbyists, 'Hot Air' is the urgent story of how the science was developed, how it has been repeatedly sabotaged and why humanity hasn't a second to spare in the fight to halt climate change.
