to learn: WATCH Segalstad's "CO2 Experiment".
This video shows that a
candle floating on water, burning in the air inside
a glass, converts the oxygen in the air to CO2.
The water rises in the glass because the CO2,
which replaced the oxygen, is quickly dissolved in
the water. The water contains calcium ions Ca++,
because we initially dissolved calcium hydroxide Ca(OH)2
in the water. The CO2 produced during oxygen
burning reacts with the calcium ions to produce solid
calcium carbonate CaCO3, which is easily
visible as a whitening of the water when we switch
on a flashlight. This little kitchen experiment demonstrates
the inorganic carbon cycle in nature. The oceans take
out our anthropogenic CO2 gas by quickly
dissolving it as bicarbonate HCO3-,
which in turn forms solid calcium carbonate either
organically in calcareous organisms or precipitates
inorganically. The CaCO3 is precipitating
and not dissolving during this process, because buffering
in the ocean maintains a stable pH around 8. We also
see that CO2 reacts very fast with the
water, contrary to the claim by the IPCC that it takes
50 - 200 years for this to happen.
this for yourself in your kitchen!

real cross-disciplinary Climate Science
with top geologist Ian Plimer: part 1
"I worked as the head
of the NASA Weather and Climate Program
which included up to 300 scientists in NASA,
in academia, and in the private sector...
Jim Hansen had... some very powerful political
friends. Al Gore was a Senator... and subsequently
became Vice President of the US. Now there
isn't too much a NASA person can do when
he's up against that kind of a challenge...
In the early '90's I realized the whole
thing was a great big fraud... Recent developments
have convinced me that it is my duty to
speak out, and to help educate the public
about what we're going to get into if we
don't stop this nonsense".

the humour here
if you still believe in global warming
Problems: Dr Theon, Hansen's former
boss, finally speaks out against Hansen
