The science on this year’s Cape Farewell has been split into two (linked) sections. We want to build on previous visits to Svalbard (2003,04 and 07) by repeating a cross section through the West Spitsbergen current (part of the extension of the Gulf Stream) and measuring the East Spitsbergen current for the first time (the other half of that e… Read the full story on TreeHugger

Last Pure Air Particles on Earth Captured for Climate Science

Posted on September 22, 2010 by Benny Hollywood| Leave a comment

Photo via MyFavoritePetSitter In order to know what the emissions and pollution created since the industrial revolution have really done to our air quality, researchers need to know what the air was like before we discovered our affinity for factories. To do that, they have to scout out the last places on earth where the air has stayed unaffected by everything we’ve pumped into it. It sounds like an impossible task, but researchers have found a spot above the Amazon Basin of Manaus that seems to fit the bill. They’v… Read the full story on TreeHugger

But It Will Take Longer for Holes at the Poles According to a report titled “Scientific Assessment of Ozone Depletion 2010” by U.N. scientists, the ozone layer has finally stopped thinning and could recover to pre-1980 levels by 2045-2060, though the annual springtime ozone hole over Antarctica (pictured above) is not expected to recover until 2073. The Montreal Protocol that banned many ozone-depleting chemicals, signed in 1987, is mostly responsible for the recovery…. Read the full story on TreeHugger

Solar Cell Production Increases 51 Percent

Posted on September 21, 2010 by Benny Hollywood| Leave a comment

Image credit: Pink Dispatcher /Flickr Solar photovoltaic (PV) cell manufacturers produced a record 10,700 megawatts of PV cells globally in 2009—an impressive 51-percent increase from the year before. While growth in 2009 slowed from the remarkable 89-percent expansion in 2008, it continued the rapid rise of an industry that first reached 1,000 megawatts of production in 2004. By the end of 2009, nearly 23,000 megawatts of PV had been installed worldwide, enough to power 4.6 million U.S. homes. Solar PV,… Read the full story on TreeHugger

Does it save you money? Is it available in my area? These are all questions that we’re going to answer today…. Read the full story on TreeHugger

The U.S. Clean Air Act is 40! Happy Birthday!

Posted on September 15, 2010 by Benny Hollywood| Leave a comment

Photo: Flickr , CC Time Flies When You’re Cleaning the Air The Clean Air Act was signed by President Richard Nixon on December 31, 1970, and so it is 40 this year. To celebrate, the U.S. Environmental Protection Agency (EPA) is looking back at the past few decades to see how things have changed and what kind of impact this important piece of legislation had on air quality in the U.S. (and around the world, since there’s only one atmosphere, and many other countries follow U.S. regulations pretty closely).
