Oceans absorbing less greenhouse gases |

NORFOLK, England, Oct.
20 The levels of CO2 uptake in the North Atlantic have
dropped by half suggesting an increase in the effects of
global climate change, a recent study
finds.
Researchers at the University of East
Anglia measured carbon dioxide uptake using automated
instruments fixed to merchant ships.
The 10-year
study found that CO2 uptake decreased by half between
the mid-1990's and 2000 to 2005.
The oceans and
the ecosphere supply the Earth's primary carbon sinks,
absorbing greenhouse gases some say contribute to global
warming.
The findings, published in the Journal
of Geophysical Research, did not conclusively indicate
the source of the decreased rate, but scientists are
concerned the oceans may in time become saturated with
CO2 and reflect the gas back into the atmosphere, the
BBC's reported.
Increased levels of so-called
greenhouse gases in the atmosphere contribute to global
climate change through a warming
effect.

Estimate of CO2 uptake

| It has been estimated that nature will
absorb 30% less of the CO2 out of the air by 2030.
This has not been factored into the calculation of
how much we have to cut emissions. Furthermore,
nature will be emitting far more greenhouse gases
(like CO2 and CH4) into the air as the world
warms. This has also not been factored into the
amount of emissions we have to cut to avoid
dangerous warming.

Gosh!

"Increased levels of so-called greenhouse
gases in the atmosphere contribute to global
climate change through a warming
effect."
Does this mean that the oceans
contain a lot less water, the most important
greenhouse gas by far?
I'm astonished what
one oil company can do...
