Study report release held back, Gag order on Fukushima radiation leak effects on Lanka?

A crucial report on the import of sea food, especially from Japan and Thailand, would be further delayed as a study to verify whether Sri Lanka is really prone to radiation leaks, from the Fukushima nuclear disaster, has been put on hold. The expert committee’s scientific report, on the baseline …

Environmentalists urge immediate action on India’s controversial Sethusamudram project

Local environmentalists have called for an immediate joint Environmental Impact Assessment (EIA) by Sri Lankan and Indian authorities on the proposed Sethusamudram project, as the Congress-led UPA government in India has decided to go ahead with the project after ignoring opposition by experts. Reiterating their strong opposition to the Sethu …

Justice Department deal reduces BP's Deepwater Horizon fine by $3.4bn

Court reduces company's maximum fine a week before trial over blowout that dumped millions of gallons of oil into Gulf of Mexico A court order, handed down by a judge in New Orleans, means BP will no longer be liable for a maximum of $21bn in fines at next week's …

Climate change severe threat to marine turtles

Scientists have sounded the alarm over the mounting threat to marine turtle populations worldwide from climate change and coastal development. The scientists have made a strong pitch for protecting key nesting grounds, and areas that may be suitable for the purpose in the future, to ensure that the marine reptiles …

Testing paradigms of ecosystem change under climate warming in Antarctica

Antarctic marine ecosystems have undergone significant changes as a result of human activities in the past and are now responding in varied and often complicated ways to climate change impacts. Recent years have seen the emergence of large-scale mechanistic explanations–or “paradigms of change”–that attempt to synthesize our understanding of past …

U.S. Department of Justice claims a wild card in BP oil spill civil deal

BP could be nearing a settlement of federal claims with the U.S. Department of Justice, but people tracking the case closely say the company and coastal states, especially Louisiana, might still be far apart. So unless the talks with the states quicken or the judge delays the process in the …

Thousands of seabirds may be harmed by oil off UK coast

As conservationists clean up hundreds of birds coated in refined mineral oil, experts fear many more may be suffering at sea Thousands of seabirds may have been harmed by a pollutant in the waters off the south coast of the UK, conservationists warned on Friday. Tests by the Environment Agency …

Ocean acidification causes ecosystem shifts via altered competitive interactions

Ocean acidification can alter competitive dynamics between species. Although calcareous species recruited and grew at similar rates to fleshy seaweeds in ambient and low pH conditions, at later stages, in low pH, they were rapidly overgrown. These results suggest that changes in competitive balance could indirectly lead to profound ecosystem …

Nutrient enrichment can increase the susceptibility of reef corals to bleaching

Increased dissolved inorganic nitrogen (DIN) concentrations in sea water have been linked to a reduction of the temperature threshold at which corals bleach, however, the mechanism underlying this change is not known. This phenomenon is now explained in terms of increased phosphatase activities and imbalanced DIN supply resulting in phosphate …

Limiting global warming to 2 °C is unlikely to save most coral reefs

Comprehensive computer simulations show that coral reefs are likely to suffer extensive long-term degradation resulting from mass bleaching events even if the expected increase in global mean temperature can be kept well below 2 °C. Without major mitigation efforts to limit global warming significantly, the fate of coral reef ecosystems …

Africa environment outlook 3: summary for policy makers

The UNEP has released the Third African Environment Outlook (AEO-3) Summary for Policy Makers, commissioned by the African Ministerial Conference on the Environment (AMCEN).

Judge Accepts BP’s $4 Billion Criminal Settlement Over Gulf Oil Spill

A federal judge in New Orleans on Tuesday approved an agreement between BP and the Justice Department for the company to plead guilty to 14 criminal charges and pay $4 billion in penalties for the 2010 oil well blowout and spill in the Gulf of Mexico that left 11 workers …

Toxicity of deepwater horizon source oil and the chemical dispersant, corexit® 9500, to coral larvae

Acute catastrophic events can cause significant damage to marine environments in a short time period and may have devastating long-term impacts. In April 2010 the BP-operated Deepwater Horizon (DWH) offshore oil rig exploded, releasing an estimated 760 million liters of crude oil into the Gulf of Mexico. This study examines …

Global mercury assessment 2013

An estimated 260 tonnes of mercury previously held in soils is being released into rivers and lakes reveals this new UNEP study which focuses on worldwide atmospheric mercury emissions, releases to the aquatic environment, the transport and fate of mercury in the global environment. Communities in developing countries are facing …

Mercury: time to act

This report speaks directly to governments involved in development of the global treaty on mercury. It presents updates from the UNEP Global Mercury Assessment 2013 in short and punchy facts and figures backed by compelling graphics that provide governments and civil society with the rationale and the imperative to act …

Wildlife in a warming world: confronting the climate crisis

The climate crisis is already changing the playing field for wildlife and urgent action is needed to preserve America’s conservation legacy, according to a new report released by the National Wildlife Federation.
