Rising ocean acidity worst for Caribbean and Pacific

Lisbeth Fog — Tue, 07 Feb 2012 15:35:00 EST

The current trend of increasing ocean acidification, which threatens fisheries around the world, is driven mainly by man-made changes and is higher even than that seen at the end of the last ice age, some 11,000 year ago, a study has said. Much of the carbon released by human activity ends up in the oceans, increasing their acidity and reducing the growth of corals and molluscs, which in turn may affect fisheries and aquaculture.

Dune Flows

Andy Soos, ENN — Tue, 07 Feb 2012 10:00:00 EST

Sand dunes flow over the land subject to the winds like ocean waves or rivers. What makes them move? What makes them start or stop? In a study at the White Sands National Monument in New Mexico, University of Pennsylvania researchers have uncovered a unifying mechanism to explain the beautiful dune patterns that occur. The findings may also hold implications for identifying when dune landscapes like those in Nebraska's Sand Hills may reach a tipping point under climate change, going from valuable grazing land to barren desert.

A Shining Star of Bipartisan Cleantech Support

David Gold — Mon, 06 Feb 2012 17:12:00 EST

Amid all the negative publicity that Solyndra's failure has brought to the Administration's cleantech efforts, one cleantech program has received broad bipartisan support: DOE's Advanced Research Projects Agency – Energy (ARPA-e). In 2012, ARPA-e will receive $275 million, a 53% increase from the prior year with both the House and the Senate supporting significant funding for the agency's third year of operations. ARPA-e is modeled after the Defense Advanced Research Projects Agency (DARPA), which for over 50 years has funded early-stage research projects that show the potential to develop technologies that could yield disruptive advances for the military. DARPA's projects have resulted in major leaps including, but definitely not limited to, the Internet, stealth technology and the Global Positioning System. Both agencies operate by soliciting proposals from companies, universities, and labs within broad thematic areas and select the most promising proposals for grant awards. Readers of my blog know that I am not a big fan of some of the Administration's cleantech efforts. ARPA-e is at least one exception. Authorized in the last year of the Bush Administration and initially funded through the Obama Administration's American Recovery and Reinvestment Act (ARRA), the ARPA-e program may be one government program that can help seed the disruptive advances needed in our energy economy.

Once, men abused slaves. Now we abuse fossil fuels

Pointing out the similarities (and differences) between slavery and the use of fossil fuels can help us engage with climate change in a new way, says Jean-François Mouhot, visiting researcher at Georgetown University, USA. In 2005, while teaching history at a French university, I was struck by the general disbelief among students that rational and sensitive human beings could ever hold others in bondage. Slavery was so obviously evil that slave-holders could only have been barbarians. My students could not entertain the idea that some slave-owners could have been genuinely blind to the harm they were doing. At the same time, I was reading a book on climate change which noted how today's machinery – almost exclusively powered by fossil fuels like coal and oil – does the same work that used to be done by slaves and servants. "Energy slaves" now do our laundry, cook our food, transport us, entertain us, and do most of the hard work needed for our survival.

Heat is Power Association Launches

Kelsey (Walker) Southerland, Executive Director, Heat is Power Association — Tue, 07 Feb 2012 15:16:00 EST

In his recent State of the Union address, President Obama called upon an America built to last, "an economy built on American manufacturing, American energy, skills for American workers, and a renewal of American values." Today, the Heat is Power Association is ready to answer this call in this country and beyond. A coalition focused on the wide-scale development of a robust Waste Heat to Power (WH2P) market re-launched today as the Heat is Power Association to bring together everyone with a stake in clean energy and industry to capture an opportunity we're wasting every day—waste heat. And we're not alone. From the White House to the campaign trail to state houses across the country, almost everyone can agree on two things: that the way to spur the global economy is through manufacturing, and we must shore up clean energy supplies to power and protect cities and towns everywhere. Alongside President Obama's call for a renewed manufacturing sector, he touted the thousands of jobs that have been created at the hands of clean energy investments. By expanding our focus on the output of energy resources – emission-free electricity – we can grow those numbers exponentially.

The Super Green Bowl

Kara Scharwath — Fri, 03 Feb 2012 07:20:00 EST

For the past 18 years, the NFL has been working to decrease the environmental footprint of the largest annual sporting event in the U.S. – the Super Bowl. Two years ago, we wrote about several initiatives aimed at reducing the events’ impacts. Last year, we covered how Super Bowl XLV was slated to be the greenest NFL championship game in history. This year, the NFL is trying to outdo itself yet again by working with the Green Mountain Energy Company and the Indianapolis community to make Super Bowl XLVI the greenest yet. I talked with Jack Groh, Director of the NFL’s Environmental Program, to get the details on this year’s efforts.

Carbon Source or Carbon Sink: Greenhouse Gases in the Tropics

David A Gabel, ENN — Thu, 02 Feb 2012 09:47:00 EST

The lush vegetation wrapping the center of the globe is one of the most important features for regulating a stable climate in the world. Much excess CO2 emissions from industrialized regions find their way to the equator to be absorbed by abundant CO2-consuming plant life. However, as large tracts of tropical rainforest are cut down in the Amazon, Congo, and Southeast Asia, worries have grown that this vital region may turn from a carbon sink to a carbon source. Those worries can be put at ease somewhat thanks to a recent study from the Woods Hole Research Center (WHRC). Their report suggests that carbon storage of forests, shrublands, and savannas in the tropics are 21 percent higher than previously believed.
