The dems obviously have a “circular list” for the causes of “global warming”. They try each one, in order, until each one is debunked, and then start over again.
I think we ran this rabbit about “freon” years ago. It got “regulated”, expensive, and replaced. Turns out the main instigator of the “pollution” rumor was the proponent of the freon replacement.
They pick the items to ban, based on the misery level it would cause the public. They get the most attention. Meanwhile, a Gore basks in his mansions, Leo flies his jet, and Kerry reminisces about his “glory days” in Vietnam...with his Purple Heart and the bandaid that earned it form him displayed in the same frame.
You are absolutely correct. Freon AKA CFCs were once used as a hairspray propellant and to my knowledge no one was complaining about health issues from it that I am aware of. CFCs were of course replaced with HFCs which break down more quickly in the atmosphere before they can reach the ozone layer. The left has a schizophrenic view of Ozone. It is considered a dangerous pollutant at lower levels in the atmosphere. However ozone in the upper levels of the atmosphere must be protected because it filters out UV radiation.
The Ozone “hole” over Antarctica was first discovered in 1985 but it is now known that it is a cyclic phenomena that most likely started long before people began using CFCs. It's size seems to have little if any correlation with the release of Freon into the atmosphere. None of the extreme claims that were made to scare politicians into agreeing to the “Montreal Protocol” in 1987 came to pass. By the early 1990s long before the “Protocol” had any effect on the amount of Freon being produced or released into the atmosphere the “hole” had shrank significantly. The thickness of the “Ozone layer” has varied little. The measured level of UVB reaching the earth's surface has not had any statistically significant trend at all.
Al Gore in his 1992 book “Earth in the Balance” claimed that because of the Antarctic ozone hole, “hunters now report finding blind rabbits” and “fisherman catch blind salmon.” This was all shown to be nonsense, so he doubled down on a new hysteria in his book and movie an inconvenient truth.
Strangely enough one of the biggest proponents of replacing CFCs with HFCs was Dupont whose patents just happened to be expiring.
