Nah... time for work. I was stupid for venturing back into Tinderbox anyways... I get dumber every time I revisit this sandbox

same old snark with no substance

my response to the questions posed by mmmbeans after that attempted to note the things we knew for a fact just a short time ago that turned out to be completely false. The concept of scientists being wrong while quoting hard facts flies over the head of most on this page.

I'm outty... have fun with lack of reading comprehension

it's rare that i see you post anything that isn't fringe stupidity. lack of substantive responses reflects the lack of substance in your posts.

Wait, what? Are you talking about the CFC thing you posted? You were serious about that?

CO2 being a greenhouse gas is no more in dispute than CFCs cause a breakdown of O3.

The catch for the latter is justifying how a heavier-than-air molecule gets miles above the surface to perform this breakdown. Yet is was accepted as a slam dunk for anyone in the know about science just two decades ago.

Wait, do you really think that heavier than air particles can't reach the stratosphere?

Sure they can... with volcanoes throwing them up there by force. Hence, the reason why the ozone hole gets bigger after an eruption.

I suppose that is devoid of substance though... stupid science and its useless factoids

The idea that heavier particles will not naturally rise in the atmosphere is based on the assumption that diffusion is the dominant form of atmospheric circulation. Yet diffusion is very slow, and anyone who has been outside on a windy day knows the atmosphere doesnt circulate slowly.

Basic meteorology will tell you that vertical mixing in the atmosphere happens all the time as high and low pressure systems move across earth's surface. Its not like this stuff is a mystery, people collect samples all the time from the upper atmosphere to learn more about atmospheric chemistry. In the case of ozone, chlorofluorocarbons (CFCs) used as coolants at the surface mix with the atmosphere, and eventually reach the stratosphere where they destroy ozone. Its not conjecture, its a well understood mechanism

Agreed. it is well understood. Volcano erupts. Ozone holes form

Well volcanoes have little to do with the ozone hole and even less to do with atmospheric circulation. The ozone hole was tiny to non-existent prior to the 1980s and has begun to decline as the long lived CFCs slowly dissipate since we stopped using them.

Volcanoes do produce aerosols, which can lead to ozone destruction, but this is typically at mid latitudes and not around the poles where the ozone hole is found. This is why volcanic activity has no effect on the size of the ozone hole.

Volcanoes also do nothing to explain the appearance/ disappearance of the ozone hole every spring and summer in the antarctic. This is because the ozone hole is caused by very cold temperatures forming polar stratospheric clouds (PSCs), which are sites for free radical formation for Chlorine containing species. Once the sun returns in the antarctic spring, these chlorine radicals photolyse and destroy ozone.
