And there is one man and according to him the so-called climate change is one of the greatest frauds in the history of science. So why do we believe in climate change? What is the human impact on climate? Is it true that weather was different ten or twenty years ago? Do we need to reduce emission of carbon dioxide? To find the answers to these questions we talked to dr Martin Hertzberg who has a Ph D in Physical Chemistry from Stanford.
