How Wind Farms Affect the Global Climate
April 5, 2010 11:13 AM - David A Gabel, ENN

Wind energy has been a fast growing sector of the overall energy market. It is renewable energy that can be produced on an industrial scale that can rival the older established energy sources of coal, gas, oil, hydro, and nuclear. Now, it accounts for only two percent of the whole energy market, but government officials expect wind to produce one fifth of the total electricity supply in the United States by 2030. Proponents claim wind power can reduce the threat of global warming. However, a recent study from the Massachusetts Institute of Technology (MIT) has found that the opposite is true. Mass produced wind farms can actually affect climate in a negative way.

Canada, US to collaborate on Greenhouse Gas Emissions Regulations
April 2, 2010 07:10 AM - Reuters

Canada will not unilaterally impose limits on greenhouse gas emissions from industry, saying on Thursday that it will work in tandem with the United States, as it is doing with vehicle standards. "We don't anticipate doing this alone. Industrial regulations will require the same kind of collaboration that we've had with the United States on the transportation sector," Environment Minister Jim Prentice told Reuters.

A New Geologic Era
April 1, 2010 03:21 PM - Andy Soos, ENN

It is a new age of geological time or so some say called the Anthropocene Epoch. This is noted in the in the journal Environmental Science & Technology. (web issue March 29; print issue April 1). This is because of the dramatic recent or potential changes in the world such as climate warming and species extinction. The dawning of this new epoch may include the sixth largest mass extinction in the Earth's history. Whether the new era will be dramatic as the Jurassic with the end of the dinosaur is still to be determined.

New Aggressive National Fuel Economy Standards Set for Passenger Cars and Light Trucks

No fooling, the DOT and EPA, in response to one of the Obama Administration’s top priorities, have jointly established aggressive new federal rules that will significantly increase the fuel economy of all passenger cars and light trucks sold in the United States. They have also established new federal rules that would for the first time ever, set national greenhouse gas (GHG) emissions standards for these vehicles.

More Accurate Emissions Data Needed Worldwide, U.S. Researchers Say

A lack of trust wafted through the Copenhagen air when negotiators gathered at December's United Nations climate summit. While many developing countries offered emission reduction commitments, several delegates from industrialized nations remained unconvinced that such reductions could be proven.

Pollution during Asian Monsoon reaches Stratospheric Heights
March 29, 2010 11:00 AM - David A Gabel, ENN

The economic growth in much of Asia has been quite remarkable in the last few decades. Unfortunately, along with growth comes intense pollution and atmospheric degradation. Pollutants from the region are being carried upward into the stratosphere during the monsoon season. Findings from a new study conducted by scientists at the National Center for Atmospheric Research (NCAR) provide evidence of the global nature of this atmospheric phenomenon.

First Wind Receives DOE Loan Guarantee to Finance Construction of Oahu-based Kahuku Wind Project

03/05/2010 - First Wind, an independent US-based wind energy company, today was offered a conditional commitment from the US Department of Energy (DOE) for a $117 million loan guarantee to finance the construction of its proposed 30 megawatt (MW) Kahuku Wind project. Located in Kahuku, Hawaii, the project will have the capacity to generate enough clean, wind energy to power about 7,700 Oahu homes each year. First Wind plans to include innovative technology in this project, including a battery energy storage system.

Mongolia winter kills herds

A severe winter has left 4.5 million dead animals in stockyards across the Mongolian steppes, and many poor herders face the loss of all their property just before the important breeding season. About a tenth of Mongolia's livestock may have perished, as deep snows cut off access to grazing and fodder. The damage to the rural economy could increase demands on Mongolia's already-stretched national budget, which relies on mining revenues to meet spending commitments. The Red Cross launched an emergency appeal for 1 million Swiss francs to assist Mongolian herders, after it estimated that 4.5 million livestock have died in the country since December.

Abu Dhabi building carbon-neutral city
March 28, 2010 10:00 AM - Tom Heap, BBC, Environmental Health News

The world's first zero-carbon city is being built in Abu Dhabi and is designed to be not only free of cars and skyscrapers but also powered by the sun. The oil-rich United Arab Emirates is the last place you would expect to learn lessons on low-carbon living, but the emerging eco-city of Masdar could teach the world. At first glance, the parched landscape of Abu Dhabi looks like the craziest place to build any city, let alone a sustainable one. The inhospitable terrain suggests that the only way to survive here is with the maximum of technological support, a bit like living on the moon.

Earth Hour 2010

Sydney's iconic Harbour Bridge and Opera House temporarily went dark on Saturday as nations across the western Pacific turned out the lights for Earth Hour 2010 to call for action on climate change. The symbolic one-hour switch-off, first held in Sydney in 2007, has become an annual global event and organizers World Wide Fund for Nature (WWF) said they expect this year's to be the biggest so far. The remote Chatham Islands was the first of more than 100 nations and territories to turn off the power at 8.30 p.m. local time, in a rolling event around the globe that ends just across the International Dateline in Samoa 24 hours later.
