Global Warming to Create "Permanent" Ocean Dead Zones?Ker Than

Fish and other marine life could be left gasping for breath in oxygen-poor oceans for thousands of years to come if global warming continues unchecked, scientists warn in a new study.

While previous studies have established a link between climate change and low-oxygen areas known as "dead zones," new computer simulations by Danish researchers suggest the dead zones could persist for millennia and lead to a considerable purge and restructuring of ocean life.


"Any increase in dead zones from global warming will last for thousands of years. They will be a permanent fixture" of our oceans, said lead researcher Gary Shaffer of the University of Copenhagen.

The new model tracked the effects of global warming on ocean dead zones in the eastern Pacific and northern Indian oceans for the next 100,000 years.

Oceans Warming Faster Than Realized

Heating Up June 18, 2008 -- The world's oceans have warmed 50 percent faster over the last 40 years than previously thought due to climate change, Australian and U.S. climate researchers reported Wednesday.

Higher ocean temperatures expand the volume of water, contributing to a rise in sea levels that is submerging small island nations and threatening to wreak havoc in low-lying, densely-populated delta regions around the globe.

The study, published in the British journal Nature, adds to a growing scientific chorus of warnings about the pace and consequences rising oceans.

It also serves as a corrective to a massive report issued last year by the Nobel-winning http://www.ipcc.ch/UN Intergovernmental Panel on Climate Change (IPCC), according to the authors.
