Thirty years of climate hysterics being proven wrong over and over again – by Conrad Black (National Post – June 30, 2018)

Every sane person is opposed to the pollution of the environment but there is no justification for the self-punitive nonsense of the Paris climate accord

It is 30 years this past week that Dr. James Hansen, then well into the first of more than three decades as head of the NASA (National Aeronautics and Space Administration)-Goddard Institute for Space Studies, testified to a U.S. Senate committee that the then-current heat wave in Washington was caused by the relationship between “the greenhouse effect and observed warming.”

This was the starting gun of a mighty debate about the existence, cause and consequences of global warming.

Hansen was embraced by the environmental movement, from authentic scientists like David Suzuki to well-meaning faddists like the Prince of Wales, to cynical interlopers from the defeated international left grasping at anything to debunk and confound capitalism, like Naomi Klein, to complete charlatans like former U.S. vice-president Al Gore.

In his testimony, Hansen described three possible courses for the world’s climate, depending on public policy. Business as usual was the first case, which would accelerate carbon dioxide emissions, at the same rate of annual increase it had reached in the late 1980s, which, he said, would produce a one Celsius degree increase in the world’s temperature within 30 years.

The second case, which Hansen believed the most likely, was that emissions would increase at the same rate they had achieved in 1988, but not greater, which would produce a world temperature increase of seven-tenths of one Celsius degree by now.
