A huge tsunami struck American Samoa and Samoa early day, causing many deaths in both Pacific island groups. Reports from Sky News put the death toll in American Samoa at 14, while Radio New Zealand reports at least five confirmed deaths in Samoa so far.

Google Earth Application Maps Carbon's Course

Google Earth -- the digital globe on which computer users can fly around the planet and zoom in on key features -- is attracting attention in scientific communities and aiding public communication about carbon dioxide.

What Makes Europe Greener than the U.S.?
September 28, 2009 09:49 AM - Elisabeth Rosenthal, Yale/Environment 360

The average American produces three times the amount of CO2 emissions as a person in France. A U.S. journalist now living in Europe explains how she learned to love her clothesline and sweating in summer.

Climate Changes Outpacing Worst-case Projections
September 28, 2009 06:20 AM - Gerard Wynn, Reuters

Global temperatures may be 4 degrees Celsius hotter by the mid-2050s if current greenhouse gas emissions trends continue, said a study published on Monday. The study, by Britain's Met Office Hadley Center, echoed a U.N. report last week which found that climate changes were outpacing worst-case scenarios forecast in 2007 by the U.N.'s Intergovernmental Panel on Climate Change (IPCC).

Carbon Cycling Processes Of Inland Waters are Important to Understanding Climate Change

In a paper titled "The Boundless Carbon Cycle," published in the September issue of Nature Geoscience, scientists from the University of Vienna, Uppsala University in Sweden, University of Antwerp, and the U.S. based Stroud┢ Water Research Center argue that current international strategies to mitigate manmade carbon emissions and address climate change have overlooked a critical player - inland waters. Streams, rivers, lakes, reservoirs, and wetlands play an important role in the carbon cycle that is unaccounted for in conventional carbon cycling models.

Burning Leaves is Bad News

Remember the smell of burning fall leaves wafting through the air? Good memories, indeed, but best that they remain just memories. Burning leaves is bad news. This practice is now illegal – or at least highly discouraged – in most areas.

Greenhouse Gas Reporting Requirements Finalized
September 25, 2009 07:08 AM - R. Greenway, ENN

A major new regulatory requirement, starting January 1, 2010, will affect most large industrial and utility combustion sources in the US. Fossil fuel and industrial GHG suppliers, motor vehicle and engine manufacturers, and facilities that emit 25,000 metric tons or more of CO2 equivalent per year will be required to report GHG emissions data to EPA annually. This threshold is equivalent to about the annual GHG emissions from 4,600 passenger vehicles.

Water Contamination Concerns Linger For Shale Gas
September 24, 2009 10:57 AM - Tom Gjelten, NPR

Advances in technology have helped boost the growth of shale drilling in the United States over the past few years. But as the practice of harvesting natural gas embedded in shale rock deep below the Earth's surface has expanded, it has raised concerns about the impact this type of drilling has on the environment — especially on groundwater.

Woodstoves and Pellet Stoves

Cleaner ways to burn an ancient fuel Humans have been using wood fires for heating somewhere between 400,000 and a million years. Today, though, using wood involves some compromises. Modern wood-burning systems have much, much lower emissions than old ones, but still can emit more than 100 times as much pollution. This article outlines some cleaner ways to burn an ancient fuel

China Pledges to Curb CO2 Emissions
September 23, 2009 06:57 AM - Paul Eckert and Claudia Parsons, Reuters

Chinese President Hu Jintao on Tuesday promised to put a "notable" brake on the country's rapidly rising carbon emissions, but dashed hopes he would unveil a hard target to kickstart stalled climate talks. The leader of the world's biggest emitter told a U.N. summit that China would pledge to cut "carbon intensity," or the amount of carbon dioxide produced for each dollar of economic output, over the decade to 2020.
