A new lesson (24/08/22 16:58:40)
    I knew about chlorofluorocarbons (freons) that were ozone layer destroyers, and their replacements in asthma inhalators, which were greenhouse gases and less fearsome back in the 1990s. But I did not know about sulfur hexafluoride.

    2According to the Intergovernmental Panel on Climate Change, SF
    6 is the most potent greenhouse gas that has been evaluated, with a global warming potential of 23,900 times that of CO
    2 when compared over a 100-year period.[40] Sulfur hexafluoride is inert in the troposphere and stratosphere and is extremely long-lived, with an estimated atmospheric lifetime of 800–3,200 years.2

    (https://en.wikipedia.org/wiki/Sulfur_hexafluoride)

    It only serves to show that policy changes are more complex than politicians can imagine. Even well-educated and interested lay people like myself fall behind.

    At least we now have people who listen, and a relevant and useful shitstorm.
