Another good explanation for causes of "global warming"

"Blame it on the Sun
So what drives global climate, if not greenhouse gas concentrations? Well,
maybe it's the sun.

There are three variables affecting the Earth's orbit--orbit shape, tilt,
and wobble--which profoundly affect weather patterns. The Earth's orbit does
not form a circle as it moves around the sun--it forms an ellipse, passing
further away from the sun at one end of the orbit than it does at the other
end.

During a 100,000-year cycle, the tug of other planets on the Earth causes
its orbit to change shape. It shifts from a short, broad ellipse that keeps
the Earth closer to the sun, to a long flat ellipse that allows it to move
farther from the sun and back again.

At the same time the Earth is orbiting, it also spins around an axis that
tilts lower and then higher during a 41,000-year cycle. Close to the poles,
the contrast between winter and summer is greatest when the tilt is large.
The Earth wobbles because it is spinning around an axis that tilts back and
forth. Thus, a temperature drop occurs in the Northern Hemisphere when it
tilts away from the sun; then the same thing happens in the Southern
Hemisphere and again in the North, in a 22,000-year cycle.

We know from simple physics that the additional energy added to the climate
system by the doubling of atmospheric CO2 is about four watts per square
meter (W/m2)--a very small amount of energy when compared to the 342 watts
per square meter added by the sun's radiation at the top of the atmosphere,
and small also when compared to natural variations in the amount of
radiation the sun sends toward the Earth.

The possible increase in energy stored in the atmosphere due to human
activity is also small when compared to uncertainties in the computer
simulations of the Earth's climate used to predict global warming. For
example, knowledge of the amount of energy flowing from the equator to the
poles is uncertain by an amount equivalent to 25 to 30 W/m2. The amount of
sunlight absorbed by the atmosphere or reflected by the surface is also
uncertain, by as much as 25 W/m2. Some computer models include adjustments
to the energy flows of as much as 100 W/m2. Imprecise treatment of the
effect of clouds may introduce another 25 W/m2 of uncertainty into the basic
computations. (2)

These uncertainties are many times larger than the four W/m2 input of energy
believed to result from a doubling of CO2 concentration in the atmosphere.
It is difficult to see how the climate impact of the four W/m2 can be
accurately calculated in the face of such huge uncertainties. As a
consequence, forecasts based on the computer simulations of climate may not
even be meaningful at this time."

Of course harry, kevin and crowd will "blame it on Bush" like they do
everything else......regardless of the facts
