Nearby Asteroids
April 7, 2010 01:19 PM - Andy Soos, ENN

A newly discovered asteroid, 2010 GA6, will safely fly by Earth April 8th at 4:06 p.m. Pacific (23:06 U.T.C.). At the time of the closest approach 2010 GA6 will be about 223,000 miles away from Earth - about 9/10ths the distance to the moon. The asteroid, approximately 71 feet wide, was discovered by the Catalina Sky Survey located in Tucson, Arizona. Asteroids, sometimes called minor planets or planetoids, are small Solar System bodies in orbit around the Sun; they are smaller than planets but larger than meteoroids. Such an object, if it hit the Earth, would have a major impact.

Canadian Cement Plant Becomes First to Capture CO2 in Algae
April 6, 2010 07:02 AM - Timothy B. Hurst, EarthandIndustry, Matter Network

A Canadian company called Pond Biofuels is capturing CO2 emissions from a cement plant in algae — algae the company ultimately plans on using to make biofuel. It’s no secret that the process of manufacturing cement is both energy intensive and dirty. Global cement production alone emits roughly five percent of greenhouse gas emissions annually, both as a byproduct of limestone decarbonation (60%) and from the burning of fossil fuels in the cement kilns (40%). And as the demand for concrete-intensive infrastructure soars in developing countries like China and India, global emissions from cement plants–and other industrial sources–will continue to rise. But a Canadian company called Pond Biofuels sees some real opportunity in all those industrial greenhouse gas emissions. At the St. Marys Cement plant in southwestern Ontario, Pond Biofuels has become the first to successfully use carbon dioxide emitted from a major industrial source to produce high value biomass from microalgae.

Ships at Sea and What is Fair
April 5, 2010 01:42 PM - Andy Soos, ENN

Ships are responsible for 2.7% of world carbon dioxide emissions. The International Maritime Organization (IMO) estimates that these emissions could increase by 150-250% by the year 2050 in line with the expected continued growth in international seaborne trade. So how does one reduce such emissions since ships are international in nature and there are over a hundred different nations with different rules. How can one be fair and be green?

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
April 1, 2010 02:05 PM - David A Gabel, ENN

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
March 30, 2010 04:14 PM - Ben Block, Worldwatch Institute

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
March 29, 2010 08:40 AM - , Green Progress

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.
