In the Antarctic, a Huge Iceberg is About to Break off Glacier
May 10, 2009 07:31 AM - Felicity Ogilvie for The World Today

A massive iceberg with enough freshwater in it to fill Sydney Harbour 135 times over is about to break off the Mertz glacier in Antarctica. The iceberg will be 75 kilometres long and contains 750,000 gigalitres of ice which is apparently quite a lot. Scientists are not sure if it is a natural event or if global warming is to blame. But a joint Australian and French team hope to find out.

Endangered Species Act Cannot be Used in Global Warming Response
May 9, 2009 08:00 AM - ANDREW C. REVKIN, The New York Times

The Obama administration said Friday that it would retain a wildlife rule issued in the last days of the Bush administration that says the government cannot invoke the Endangered Species Act to restrict emissions of greenhouse gases threatening the polar bear and its habitat.

Licensed Site Remediation Professional program in NJ
May 8, 2009 04:00 PM - Editor, ENN

Governor Jon S. Corzine today signed legislation to reform the clean-up of contaminated sites. Licensed professionals will take over many of the more time-consuming functions that have bogged down the DEP, helping to expedite the review and approval process for contaminated sites across the state. The Licensed Site Remediation Professional will investigate sites to assess potential contamination, develop and oversee remediation approaches, and determine when a remediation is complete. They will make this determination through the issuance of a “response action outcome” (RAO) upon completion of the remediation activities. RAOs, except in cases where no contamination is detected, must be submitted to NJDEP and maybe audited

US EPA Budget Proposal Issued Today
May 7, 2009 05:00 PM - Editor, ENN

Administrator Lisa P. Jackson released EPA’s fiscal year 2010 budget blueprint, which takes significant strides to ensure that our air, land, and water are safe and clean. Expanding on the investments of the American Recovery and Reinvestment Act, this $10.5 billion budget is designed so EPA can develop programs that are good for the environment, and also aid in the economic recovery.

Nanoscale water treatment needs innovative engineering
May 7, 2009 10:36 AM - Ashok Raichur, SciDevNet

The fast-evolving world of nanotechnology captivates researchers in fields ranging from health and nutrition to agriculture and environment. In particular, many developing countries are investigating how nanotechnology might improve access to clean water. But making the leap to commercial applications is complicated and is still a distant goal for most developing countries. Just producing nanomaterials in quantities large enough for industrial applications is challenging and can be expensive.

Sea 'snake' generates electricity with every wave
May 7, 2009 10:11 AM - Colin Barras, NewScientist

Anaconda, a giant rubber "snake" that floats offshore and converts wave energy to electricity, is a step closer to commercialisation. An 8-metre long, 1/25th scale version is currently undergoing tests in a large wave tank in Gosport, UK, and a full-size working version could be a reality in five years.

Hydrogen Fuel Made Using Green Energy
May 7, 2009 09:36 AM - Irene Klotz, Discovery News

A NASA-backed group is designing a wind- and sun-powered fueling system for city buses -- and possibly other machines -- that run on hydrogen.

Sea Salt Holds Clues To Climate Change
May 7, 2009 06:37 AM - ScienceDaily

We know that average sea levels have risen over the past century, and that global warming is to blame. But what is climate change doing to the saltiness, or salinity, of our oceans? This is an important question because big shifts in salinity could be a warning that more severe droughts and floods are on their way, or even that global warming is speeding up.

Plug-In Hybrids: More Hype Than Hope?
May 6, 2009 10:07 AM - Scott McCredie, Wired

Seattle has outfitted more than a dozen Toyota Prius hybrids with new plug-in technology to squeeze even better fuel efficiency from the eco-wonder. Just over a year after performing the conversions, the city says it is thrilled with the cars. The plug-in Prius hybrids have used less gas and emitted less CO2 than their conventional counterparts. But the tests also have put a big dent in the plug-in promise.

Some Himalayan Glaciers Growing Despite Warming
May 6, 2009 07:25 AM - Michael Reilly, Discovery News

Perched on the soaring Karakoram mountains in the Western Himalayas, a group of some 230 glaciers are bucking the global warming trend. They're growing. Among legendary peaks like K2 and Nanga Parbat, glaciers with a penthouse view of the world are growing, and have been for almost three decades.
