It’s safe to assume no one consciously sets out to challenge a narrative as deeply entrenched and emotionally charged as climate change. Dr William Happer, an American physicist and Professor Emeritus in the Department of Physics at Princeton University, certainly didn’t. It was only in 1991, upon Happer’s appointment by President George W Bush as director of Energy Research in the US Department of Energy, that his interaction with climate change authorities – and their refusal to engage in customary scientific debate on climate change – piqued his interest. Thereafter, Happer was dismissed for his contrarian views and ‘head butting’ with climate change luminary Al Gore, only to be brought back to Washington by former president Donald Trump in 2018. BizNews spoke to Happer (83) about his prodigious career and discovery that the burgeoning climate change hysteria had no scientific basis. Happer meticulously detailed why and how CO2, the “demon gas”, is not a pollutant but is essential to mankind’s prosperity.
