Default Calculating your carbon footprint - a load of ********

So you believe that the greenhouse effect is nonexistant?

Since Al Gore's famous graph of CO2/temperature over the millennia was
shown to be flawed - in that the CO2 levels *lagged* climate change -
the heat has gone out of that debate, and focussed on sunspot activity
instead.


If the greenhouse effect is real, and it has been accepted as fact for
over a century, then whether or not CO2 concentrations tend to lag or
lead is an interesting side issue.

There is a rational explanation for the lag, if it really does exist, in
that some of the extra CO2 is expelled from the sea as sea temperatures
rise and the sea is such a huge heat sink that it lags years behind
atmospheric temperature trends.

The more frighetning thing is that CO2 appears to be both a cause and an
effect, of global warming: I.e. you have a nice positive feedback system
that can 'flip' the climate between a high CO2/low CO2 regime, depending
on what is stored in the oceans.

Hitherto, its probably been volcanic activity or sunspot driven: now
its fossil fuel driven.

There is an interesting balance also between coal burning and warming,
in that the short term effect of coal burning is to put up particulates
that cool the atmosphe its when you stop burning coal because of acid
rain etc, and fit exhaust catalysers to cars, that you suddenly get a
rise in temperatures. China is now burning more coal than ever..

The poles are the place that receive the least sunlight, but have the
same radiation poetntial..they are the heats sinks of the world.
Reduction in radiation from the poles by CO@ blanketing leads to rapidly
risng polar temperatures.

We are seeing rapidly rising polar temperatures.

Its probably far far too late to stop CO2 generated global warming though.

What is needed is a way to generate the massive amounts of energy we
will need to deal with its effects. An that isnt going to be
photovoltaics or windmills.
