Perhaps the BEST B1G Forum anywhere, here at College Football Fan Site, CFB51!!!

We could consider a massive worst case scenario where this thing does spiral out of control and mean temperatures increase past 40°C, a general sterilization temperature for many organisms.  Some humans would survive at high altitude even so, but food would become a problem.  Some might survive in caves if energy was not an issue.  That would be a mass extinction even obviously.

And it's too late to change it really if that is going to happen.

The mean temperature on Venus is something like 800°C.  That would kill off everything I can imagine, we'd have to be in space to survive.

Seems bad

the world started to go south when all of a sudden you couldnt buy freon

man that change sure made a big difference didnt it

nope the greeners just moved on to farting cows

The Freon story actually is a success story, in my view.  The cure didn't cost all that much and appears to be working.

While it makes for endless dad jokes, it’s a myth that cow farts cause global warming.

Cows actually burp out methane as their complex ruminant digestive systems break down plant materials, explains Dr. Sara Place, an animal scientist with the National Cattlemen’s Beef Association.

Critics often cite global averages to suggest that cattle are one of the biggest emitters of greenhouse gas, but those figures don’t tell the whole story, Place says.

Research shows that removing all livestock and poultry from the U.S. alone would only reduce global greenhouse gas emissions by 0.36 percent.

Specifically, cattle farming in the United States is the most environmentally friendly and sustainable in the world, she says.

In the last 40 years, the U.S. cattle herd has shrunk by one-third, yet U.S. farmers are producing more beef today than they did in the 1970s, Place notes.

We're also reducing emissions within the dairy industry, too. In 1950, the U.S. had 25 million dairy cows. Today, we only have 9 million. The herd has shrunk drastically, but with those 9 million cows we are producing 60% more milk, according to Dr. Frank Mitloehner of U.C. Davis.

That means that the dairy industry’s carbon footprint is down by two-thirds in the U.S. since 1950. That’s a substantial reduction in carbon dioxide and methane emissions. Fewer cows means fewer cow burps (and cow farts).

unfortunately, I know Ed Zachery what you're speaking of

another reason to move next to Utee

and just what did it do

fix the ozone

there is absolutely no proof that wouldnt have gone away on its own

and yes some day it will rear its ugly head again

and when it does by by something else that helps man live more comfortably

There is pretty convincing evidence, to me, that Freon caused damage to the ozone layer and the Montreal Accord is working.  There also is pretty good evidence that compounds like CFCs, highly halogenated hydrocarbons, are "forever compounds", once made, they don't go away in Nature, except very very slowly.

I was not aware that the replacements are all that bad for heat pumps.

Refrigerators in the U.S. consume about the same energy as 25 large power plants produce each year.
