Except everything Hansen lied about has not come to pass. The polar caps still exist. Antarctica gets record snow fall. Heat is no hotter than it was 100 years ago. Weather stations however, have never moved whilst concrete jungles have expanded, falsely altering data.
The huge difference is when climate change became big news in the late 1980s, and early 1990s, public climate change denial was almost unknown. So when scientists spoke about it, a load of people brainwashed in fossil fuel propaganda, didn't deny it, very vocally.
