Acidic oceans threaten world�s ecosystem
Deep and immediate cuts in emissions are needed to stall ocean
acidification and prevent mass extinction of marine species, food
insecurity and serious damage to the world economy, according to
International Union for the Conservation of Nature (IUCN).
Increased release of CO2 in the atmosphere is making seawater more
acidic and is threatening ecosystems and species precious for our food
and economy, according to IUCN which issued this statement:
" It is also reducing the ocean's ability to absorb CO2 and regulate
climate. Previous episodes of ocean acidification were linked to mass
extinctions of some species, and it is reasonable to assume that this
episode could have the same consequences. There can be little doubt
that the ocean is undergoing dramatic changes that will impact many
human lives now and in coming generations, unless we act quickly and
decisively."
"Ocean acidification can be best described as the evil twin of climate
change," says Dan Laffoley, lead editor of the guide, Marine Vice
Chair of IUCN's World Commission on Protected Areas and member of
Natural England's Chief Scientist's team.
"We have used story-telling to paint a picture of the many ways in
which ocean acidification may alter how the ocean works - given the
possible far-reaching consequences we hope this guide acts as a
wake-up call to decision makers to place the ocean centre stage in
climate discussions and conclusions"
The ocean provides about half of the Earth's natural resources and
humankind takes direct advantage of this through our fisheries and
shellfisheries.
The ocean also absorbs 25 percent of all the carbon dioxide we emit
each year, and produces half the oxygen we breathe.
Ocean acidity has increased by 30 percent since industrialization
began 250 years ago.
If CO2 levels in the atmosphere continue to rise, sea water acidity
could increase by 120 percent by 2060 � greater than anything
experienced in the past 21 million years.

Any idea how many "emissions" were spewed into the atmosphere by those
traveling to the clown show in Copenhagen?
• Total bullshit!!!!!
The extinction of marine species will only be
caused by overfishing. There have been many
years in the past 190 where the CO2 levels
exceeded the current levels even over 400ppm
I posted the data but many AGW fools because
they did not like the author - not fascist enough
• to get the real climate data since 1820 go to:
Message-ID: <bc421438-9c9a-420a-8151-

Balls.

Precisely.
Your point also demonstrates how responses
tailored to actual threats to the eco-system
are utterly undermined and neutered thanks
to the corporate hijacking of the once legitimate (but no longer)
green movement.
Instead of addressing real eco issues we're left with a cult
chasing ManBearPigs.
Shame really...
Show us the proof you troll.
Look at the CDIAC data in which there is no
strong evidence pf Ocean acidification
The biggest threat to the ocean ecosystem is overfishing and it will
only get worse.
No concern for the ocean?

So back up your claims that the majority of
the worlds glaciers are expanding.
"Currently more glaciers are growing than shrinking.
