Warming trends rise in large ocean areas

One-third of the world's large ocean regions are experienced two to four times greater warming trends than previously reported averages, increasing the risk to marine life and fisheries, a UN-backed environmental study has said.

Overfishing, coastal pollution and degradation of water quality were also common in all 64 large marine ecosystems studied by scientists who contributed to the UN Environmental Programme report presented in Vietnam this week.

"These marine ecosystems are under great stress and that stress is increasing because of climate change, by global warming," a co-author was reported as saying.

The report said that in 18 of the 64 regions, "the accelerated warming trends are two to four times greater than the average trends reported in 2007 by the Intergovernmental Panel on Climate Change".
