A new kind of explosive coolant called HFO-1234yf is being put into cars to fight global warming.

HFO-1234yf is already becoming standard in many new cars sold in the European Union and the United States by all the major automakers, in large part because its developers, Honeywell and Chemours, have automakers over a barrel. Their refrigerant is one of the few options that automakers have to comply with new regulations and the Kigali agreement.

It has its detractors. The new refrigerant is at least 10 times as costly as the one it replaces.

Daimler began raising red flags in 2012. A video the company made public was stark. It showed a Mercedes-Benz hatchback catching fire under the hood after 1234yf refrigerant leaked during a company simulation.

Daimler eventually relented and went along with the rest of the industry, installing 1234yf in many of its new cars.

“None of the people in the car industry I know want to use it,” said Axel Friedrich, the former head of the transportation and noise division at the Umweltbundesamt, the German equivalent of the Environmental Protection Agency. He added that he opposed having another “product in the front of the car which is flammable.”

While cars, obviously, contain other flammable materials, he was specifically worried that at high temperatures 1234yf emitted hydrogen fluoride, which is dangerous if inhaled or touched.

The new coolant is superior to the HFC it is replacing in its impact on global warming.

Man-made global warming is a myth, a fantasy; there has never even been a workable theory to even prove it.  (The current theory, that man-made carbon dioxide causes global warming, doesn't work because most CO2 is produced naturally in the environment, not by industrial output.)  And yet our lives are risked, again and again, to protect us against this fantasy.

More and more people are dying because cars are getting lighter and lighter – the left's human sacrifices to appease their global warming gods.  The left won't be satisfied until we are driving around in vehicles loaded with explosives with the crashworthiness of papier-mâché.
