On the other hand, increased atmospheric CO2 causes plants to increase
not only their growth, but the ratio of carbon fixing per lb of plant
growth.
Additionally, increased equaltorial heating (where more of these
greenhouse effect measurements are taken, on a per square mile basis,
than in polar regions) tends to reduce the efficacy of the thermohaline
conveyor system in the oceans. The Atlantinc conveyor is known as the
Gulf Stream. As this conveyor system slows, there will be less heat
transport to the poles, leading to colder temperatures in polar regions,
which I needn't further explain, is what causes ice ages.

And yet we have seen nowhere near the same level of temperature increase
relative to CO2 rise as that seen in prehistoric data gathered from ice
deposits. THis says that there must be some other mechanism in charge of
major cooling/warming trends.

200 years? You mean 20 years. According to my geologist cousin, the CO2
level's effect on global average temperature has a diminishing returns
effect that kicks in at 280 and really flattens out at 330 ppm. After
that it really doesn't have that much of an effect if it goes up
further.

ice ages.

No, there is a solid correlation between per capita income and
pollution, but it is not linear. It starts out linear at $0 up to
$10,000.00 per year, then drops down by 50% by $12500.00, and slowly
dropping further thereafter.

This is always a statistical lie tossed out by developing countries to
make the US shoulder the burden like a Sugar Daddy. They fail to say
what percent of that 25% of all fossil fuels is not burned, but is
converted into plastics and other products. THey also fail to properly
account for Chinese coal consumption. This figure is a highly classified
state secret (the true figure at least). They also fail to recognise
that the US long ago reached fill utilization of hydro resources, and
leads the world in implementation of wind and solar projects. They also,
with the exception of France, fail to mention that the only way for the
entire world to solve its fossil fuel dependency is to fully use nuclear
power.

Your second statement is an utter falsehood, while your first is
inaccurate. The advantage of following our lead is that they will be
able to take advantage of energy and fuel efficient technologies from
the start that were developed by the US. The current fuel reserves, as I
have repeatedly informed this list in the past, is merely a measurement
of known available reserves that are cost effective to recover at
TODAY's market prices. Previously unknown reserves are being discovered
every day, so much so that, depending on growth scenarios you use, we
have somewhere between 200-400 years of KNOWN fossil fuels available.
THis is not even considering the vast hydrate reserves under the ocean
bottoms that were only discovered to exist a couple of years ago. How
much oil and gas remains to be discovered is still an unknown.

A large number have in the past published, and had reviewed, data on
things like the variance in Solar Nutrino Unit (SNU) levels over time,
as well as the fact that current SNU levels, which are a product of
fusion occuring in the sun's core right now (the heat of which will
radiate to the surface within 5,000 years or so) is only 1/4 of that
deemed necessary to sustain the present solar flux levels. THis means
that, if current solar fusion models are accurate (and are no less
accurate than, say, greenhouse effect simulations) then in a few
thousand years, the sun will drop its output by a large fraction. It is
also well recognised that the end of what is known as the "Little Ice
Age" coincides with vast population and industrialisation growth (with a
concurrent increase in CO2 levels). While this (the little ice age deal)
is not currently in scientific or political vogue, in the 70's and early
80's, it was considered to be solid science.

You fail to mention that the Greenland Ice Cap, which is in reality one
huge glacier, is indeed growing.

Of course not. you fail to understand the economics of energy prices.
Tell me, when did oil companies make the biggest profits????? Duh, when
prices were sky high during the OPEC stimulated and Carter induced oil
crunch of the 70's and 80's. If energy taxes take effect, this will
increase prices, which will increase their margins, allowing oil execs
to squeeze in more profits. They also will be able to wangle huge
increases in government subsidies for energy research. Pushing oil shale
scams on the feds was one of the biggest cash cows the oil boys
perpetrated on the US and Canada.

Not so. As CO2 levels go up along with heat, and hopefully with some
stimulation from sinking a couple thousand obsolete cargo ships (all
that metal rusting stimulates plankton growth), that plankton will
flourish and become a) fishfood, which will become people food, which
will become sludge spread over the barren wastes of the midwest, the
Sahara, etc. and b) precipitating detritus settling on the ocean bottom,
to, over time become methane hydrate deposits.

How about throwing out 100 years of counterproductive waste treatment
"technology" and start spreading sludge over the desert??? There are
companies doing this now in Texas with New York City sludge (grade B
sludge).

At this point there is little for Mohammed Q. Sixpack in the sourthern
Sahara can do, as the main thing draining usable soil from the desert's
periphery is the sun and the winds. Getting Europe to ship its shit
south would do wonders.

Except for bureaucracy. The EPA, that fountain of wise and informed
environmental protection, has banned New York from dumping its sewage at
sea. Any wonder that local fisheries have plummeted???

Almost all of the data, however, are from stations in temperate,
tropical, or equatorial zones. There is very little data from subpolar
and polar regions to give such statistical pools the proper balance. As
a result the stats are merely measuring an increase in equatorial
temperatures, while the decrease in polar temperatures are swamped to
insignificance.

Sorry, wrong again. Turns out that malarial mosquitos live in swamps
that are a) not given a decent through flow of water, and b) protected
from incursions of salt water. It is the opinion of many current
wetlands experts (as seen in last months AUDOBON issue) that malarial
mosquitos are a sign of an unhealthy wetlands ecosystem. Healty wetlands
have well rounded populations of mosquito predators.

Granted, as top predators, we are getting more irresponsible, but this
is mostly because of the preference of many to descend to the level of
cattle in order to be able to increase population.
