Mike,
CO2 levels are on the rise ..... nowhere near 250% since 2000.
In the year 2000, CO2 levels were at 368ppm (vol) = .0368% of air by volume.
As of March, 2006 the CO2 levels were 381ppm = .0381% of the air by volume
..... a 3.53% increase.
If temp change caused by CO2, alone, was all we had to be concerned with,
climate change associated with it would not be very significant. The problem is
the cascading effect that even a slight temp change can initiate.
Ex. Slight increase in temp -----> less ice cover -----> less
reflected solar energy, more absorbed ----> more heat ---> less ice cover
etc
Slight increase in temp ---> melting of permafrost ----> release
of methane gas contributing to greenhouse effect ----> temp increase ----->
melting of permafrost etc.
The current 381ppm level represents a 100ppm increase over pre-industrial
levels .... a 36% increase ..... Very significant. Recent studies done
involving the analysis of air trapped in tiny bubbles in Arctic Ice, show that
changes such as these have occurred in the past, but over a much greater (as in
10's of thousands of years) rather than a few lifetimes.
There are homeostatic mechanism that allow the earth to maintain
relatively stable conditions. Large bodies of water absorb CO2. Homeostatic
mechanisms can be overloaded. Because CO2 reacts with the water to form
carbonic acid (dissociates into bicarbonate ion and hydrogen ion), over-loading
the oceans with CO2 can result in a slight drop in pH. (A similar series of
events occurs in our bodies. We transport CO2 ... as the bicarbonate ion ....
away from tissues. Increased metabolic rate ----> additional CO2 ------>
Increased carbonic acid and a very slight drop in pH of our blood. We feel the
urge to breath faster ...... result: we eliminate the CO2. Unfortunately our
large bodies of water do not enjoy such a luxury.) A slight drop in the pH of
oceans ----> breakdown and release of vast quantities CO2 sequestered in
carbonates (shells of animal great and small).
At what point does the cascade of events leading to "meltdown" occur?
..... the "Tipping Point"? Has it already occurred?
Do we just sit and do nothing?
I wish I paid more attention in English class ... Was it Dylan Thomas?
... "Do not go silent ........."
Maybe all we can do is mitigate the devastation; fight the good fight
.... Are you in?
Fatheads Unite .....

Terry...any chance you could direct us to where you read this? Last night I
was thinking about global warming and the reasons behind it and I wondered if
everything might start suffocating at some point. Now today comes your
mentioning the CO2 increase. I don't like these kind of coincidences, but they
happen. On the other hand, maybe I really shouldn't read the documentation of
this number. Maybe I shouldn't read anything about anything that seems to
really matter. "Ignorance is bliss," my wife reminds me, not because she
believes it, but because she doesn't understand why I should try to learn what
I can about something over which I have little or no control. Maybe she's
right, but I'm a fathead and want to know anyway. Thanks. Mike DuPree
