The change had nothing to do with patents in the first place...
The patents for R12 went out in the 1950's, and a number of companies
were making that product.
There is now a global ban relating to chlorofluorocarbons, but it is not
totally phased out yet.
Measurements by the Japanese and by NASA have showed that the
ozone hole is healing and the CFC levels are dropping..
I just had my 90 Reatta converted to R134, and it works fine, is
easy to come by. I had to replace the compressor anyway, due to
a leak, so went the whole way.
A while back, I did some back-of-the-envelope calculations using figures
from NASA and envirowhackos. I wildly overestimated world R12 production
since its invention, and placed ALL of it into a cubic mile of stratosphere,
and using NASA's estimate that 1 molecule of R12 destroys 100,000 molecules
of ozone, I couldn't destroy all the ozone in that cubic mile, even
when I shut off the sun's ability to make new ozone there. Now, my
calculations could be off by an order of magnitude or two. But when you
consider how hugely many cubic miles of stratosphere there are, it begins
to be clear that my figures can't possibly be that far off.
It's incredibly arrogant to believe that mankind could possibly ever do
anything to cause such major change to Earth as damaging the ozone hole
or global warming.
The news services used to report that scientists said that ozone was a
major component of smog. Obviously, you have proven them wrong.
Now will you get the weather forecasters to quit issuing those bogus
Believe what you want....
Environment is a broad subject. Recent surveys, which I am sure many of you
believe anyway, indicate that there are now only about 10% of the fish in
the sea that
there were a few decades ago. That was a resource we thought was impossible
kill off because it was so vast. But we seem to be managing it.
This is a result of overfishing and pollution, apparently.
New studies published just last week estimate that the northern polar ice
cap will disappear totally,
and will not refreeze, within the century. Earliest models show it will
happen by 2040, but others say
it might last until nearer 2100.
IF TRUE ( and we can argue whether it is or not...neither of us knows, one
way or the other) this
seems serious, for our children. Most of us are old enough that we can
continue to crap in our
nests and will not live to see the outcome.
I am NOT a liar,am not uneducated, and am not stupid...
Scientific data IS up for interpretation, and there is a certain amount of
inherent in every measurement.
There is also the human tendency to deny data which is inconvenient. If
dont like the scenario, then just say it isnt so. Which are you?
I do beg to differ, NO climatological research exists to support your
claim, what does exist is modeling and simulation predicting what the
outcome *might be* (if the underlying mathematics are correct) if global
warming was in-fact occurring... this is not remotely-related to your
unfounded statement that research shows any such thing... more unfounded
Computer modeling and simulation is used in hundreds of industries to save
millions of dollars in testing. It has proven it's worth over and over and
In fact one of the earliest industries to do it was the military industrial
If anything, the climatologists are johnny-come-latelys to the science of
If you want to dispute the global warming models then your welcome to
attack the input data being used to feed the models. But attacking the
models themselves show your nothing more than an ignorant blowhard.
One of these days when I have some time, I plan to re-do the whole process
and put it up on my web site. Right now, it's a fair amount of work that
has to wait for car repairs.
I didn't expect to convince anyone by mentioning it. I was saying that I
convinced myself, and outlined the procedure I used.
You're looking at "sources" where the CFCs actually hit the air. I was
looking at "sources" as in manufacturers. The stuff in your aerosol cans
came from the manufacturers, so it was in my estimates.
