Ask any shipyard technician whose life depends on it about how CFCs behave when released into the hull of a ship. Those still living will tell you that released CFCs are much heavier than air, that CFCs released into a ship's hull will sink, force all the air out of a hull, and leave technicians dead within hulls because there'd be no air or oxygen to breath.

The most common CFC refrigerant, R-12, is over five times heavier than air -- it drops like a rock and flows downhill as water does. A fact that environmental "scientists" don't seem to know.

When "respected" scientists support fraud, their homeland culture's corruption factor has arrived at the pure-evil level.

The most common CFC refrigerant, R-12, is over five times heavier than air -- it drops like a rock and flows downhill as water does.

Gases come in a variety of densities. While heavy gases may temporarily pool in an enclosed space, given time they will dissipate and mix with the atmosphere. If they didn't the different gases that make up air would all be stratified and there would be no measurable CFCs more than an inch off the ground.

Ok, let's say you open a cannister of r-12 at the bottom of a 1000 foot deep airtight shaft with only the top open. Let's say the bottom 50 ft. fill up with r-12. If you come back 10 years later, I think you will find that almost all of the r12 has escaped out (diffused out is probably a better term) the shaft. On a short time frame of hours, you are right, r12 sinks. On a longer time frame, it will diffuse upwards and outwards.
