Au contraire, T8 - doing the test that disproves the theory is THE
gold standard of science.

What you're seeking, with your demand for raw data and source code, is
merely an opportunity to cherry pick to enable you to ridicule - you
don't want to contribute.

No, I want the opportunity for people to test, and disprove your
theory.
There are many models in use by scientists around the world, using a
number of different datasets. How many people and how many tests do you
require?

One would suppose that such tests already have occurred many times.
After all, a scientist who was able to disprove global warming would
achieve extraordinary fame (and fortune).- Hide quoted text -

The issues:
1) We have burnt rather a lot of fossil fuels, coal, natural gas and
oil, in the last hundred years or so.
2) Many rain forests have been cut down to allow the land to used for
other purposes. Trees consume large amounts of CO2 from the atmosphere
for photosynthesis.
3) The human population is expanding at a considerable rate. At least
in the developed World all these folk expect to live in heated and air-
conditioned houses, to drive cars and to travel by aircraft.

On the other hand:
1) We seem to be living in a natural interglacial period. Only a few
tens of thousands of years ago much of North America and Northern
Europe was covered in ice.
2) There is geological and fossil evidence to suggest that it has been
hotter in previous eras, but life on earth was not wiped out.
3) Reasonably accurate temperature measurement has only been possible
for a few hundred years, so to say that there is a trend of increasing
temperatures may only be looking at a very short term and natural
variation in terms of the entire history of the planet. In any case
the average global temperature seems to have stabilised again, which
is probably why 'global warming' seems to have been relabelled as
'climate change'!
4) Better technology and better insulated buildings are reducing each
person's carbon footprint.
5) Eventually the coal and oil reserves will run out, so we won't be
able burn any more anyway, which is the best case for conserving them
as much as possible.
6) Sooner or later, something such as nuclear war, a metorite strike,
famine, an untreatable disease, or another ice age will decimate or
wipe out the human population. I bet the big dinosaurs thought they
had it made!
