ReutersOceans absorbing less CO2 may have 1,500 year impactWed Apr 16, 2008 2:06pm EDT

VIENNA (Reuters) - Global oceans are soaking up less carbon
dioxide, a development that could speed up the greenhouse
effect and have an impact for the next 1,500 years, scientists
said on Wednesday.
Research from a five-year project funded by the European Union
showed the North Atlantic, which along with the Antarctic is of
the world's two vital ocean carbon sinks, is absorbing only half
the amount of CO2 that it did in the mid-1990s.
Using recent detailed data, scientists said the amount absorbed
is also fluctuating each year, making it hard to predict how and
whether the trend will continue and if oceans will be able to
perform their vital balancing act in the future.
Oceans soak up around a quarter of annual CO2 emissions, but
should they fail to do so in the future the gas would stay in
the atmosphere and could accelerate the greenhouse effect, a
prospect project director Christoph Heinze called "alarming".
