Default A quick question, just curious really...

The only thing that is political about the rising level of CO2 in the
atmosphere was George W. Bush's attempt to end the measurements of
atmospheric CO2, begun by Charles Keeling in 1958 on Mauna Loa
http://www.esrl.noaa.gov/gmd/ccgg/trends/
They now show that the level is nearly 390 ppm, rather than the 360
ppm quoted by John Hall (IanH), and ~40% higher than the pre-
industrial level of 280 ppm.

at a ratio 1:2. so surely the O2 levels of the atmosphere will be
falling at the same rate? Should we not be overly worried about
reducing O2 rather than increasing CO2?
Does anyone here know of any research and/or results for this
happenning?


Keeling's son, Ralph, has been investigating Oxygen levels which have
been falling:
http://bluemoon.ucsd.edu/images/ALLo.pdf
1 mpeg in the N2/O2 ratio = 0.2 ppm of Oxygen, so the drop of around
400 mpeg = fall in oxygen of about 80 ppm, probably twice the rise in
CO2 over the same period, as you predicted. With a level of O2 at
around 200,000 ppm this has little effect on animal life.

Add the fact that de-forestation is happening (so we are told...again
not wanting to be all political), then any O2 is not being adequately
replaced...this would only compound the problem.


There is no doubt that the Amazon jungle is being cleared for farming.
You can see it in the satellite photographs. and since they are fairly
recent, then that gives you an idea of the speed and severity of that
problem. However, their effect on the CO2 levels is included in the
measurements, obviously.

The problem with the clearing of the jungles is not really the amount
of CO2 produced - it is that the trees are no longer there to remove
CO2. Moreover the soil that is left may release methane, a more
powerful greenhouse gas than carbon dioxide. The jungle floor also
acts as a reservoir of water shaded by the canopy. Without that
canopy the water will be lost and a desert environment will be
created. Replanting the trees might reverse that effect, but the loss
of biodiversity will lead to the extinction of animal species which
can never recover.

This could just be the indicator (or scientific cross-check) that the
CO2 levels are rising and we are not getting bogus data from any
sources.


I have only mentioned Mauna Loa because that is the most famous, but
CO2 is being measured at other sites throughout the world as is O2,
which can be seen on those charts.

So any results / research into this will be greatly and appreciatedly
received.


Anthropogenic Greenhouse Warming is not a political scam got up by the
scientists. You should no believe everything you read in the
newspapers, especially the Daily Telegraph!
