Overfishing, Other Factors Leading to Proliferation of Giant Jellyfish
June 9, 2009 07:20 AM - Discovery News and ABC Science Online

Giant jellyfish are taking over parts of the world's oceans as overfishing and other human activities open windows of opportunity for them to prosper, say researchers. Jellyfish are normally kept in check by fish, which eat small jellyfish and compete for jellyfish food such as zooplankton, researchers said. But, with overfishing, jellyfish numbers are increasing.

Chopping down fewer trees and caring for the soil may be cheaper and more effective in fighting climate change than curbing emissions from coal plants, the United Nations Environment Programme (UNEP) said on Friday.

Maldives' disappearing coast prompts appeal to UN space agency

The Maldives, one of the nations most threatened by global warming, is appealing to the United Nations space agency to help the island country plan its defenses against rising sea levels. "Beach erosion is the No. 1 problem for our country right now," Environment Minister Abdulla Shahid said over the weekend in an interview in Vienna. The Indian Ocean nation of 385,000 people has had to relocate the populations of two of its 200 islands because of eroding beaches, he said.

Coral reefs more resilient than expected-against seaweed
June 6, 2009 10:32 AM - Eurekalert

There's little doubt that coral reefs the world over face threats on many fronts: pollution, diseases, destructive fishing practices and warming oceans. But reefs appear to be more resistant to one potential menace – seaweed – than previously thought, according to new research by a team of marine scientists from the United States and Australia. Their study is the first global-scale analysis of thousands of surveys of individual reefs – in all, more than 3,500 examinations of about 1,800 reefs performed between 1996 and 2006. The study appears the June issue of the journal Ecology, which is published by the Ecological Society of America.

A World First – Tankers on Shore Power when at Dock
June 5, 2009 12:10 PM - , Triple Pundit

A major source of air pollution in port areas comes from the giant vessels that tie up at their docks to load and unload cargo. That’s because the powerful diesel engines have to run continuously to keep the ships’ equipment and support systems operating. That also means continuous spewing of GHG and diesel particulate emissions into the local air. A solution to this massive emissions problem has long existed but is not widely implemented because it involves expensive modifications both on-ship and to offshore facilities. It’s called shore power, which allows ships to shut down their diesel engines at berth and literally plug into the landside electricity grid, thus improving air quality.

Study finds forest conservation in Indonesia could be as profitable as palm oil plantations
