Water from Melting Greenland Ice Sheath May Impact Northeast US Coast
May 28, 2009 06:28 AM - Editor, ENN

New research by the National Center for Atmospheric Research points to the possibility that water from the melting Greenland Ice Sheath could change oceanic circulation in the North Atlantic, in a way that would raise sea levels off the Northeast by about eight inches more than the average global sea level rise that is expected with global warming.

NASA Supercomputers Advance State of the Art of Ocean Circulation Modeling
May 27, 2009 06:55 AM - Editor, ENN

Global scale oceanic circulation modeling has been moving to a new gridding method that projects the faces of a cube onto the surface of a sphere. They found that this method covers the sphere more uniformly than a latitude-longitude grid, and that it produces more accurate results near Earth's poles. This is helping refine modeling of ocean currents which are critical to global climate models, and has the potential to significantly improve the accuracy of climate change modeling.

Is Antarctica Cooling After All?
May 26, 2009 11:55 AM - Editor, ENN

While most of the planet has been warming for decades, part of Antartica, the East Antarctic Ice Sheet -- has actually been getting colder. At least that was the general consensus. A major study by Pennsylvania State University; NASA's Goddard Space Flight Center in Greenbelt, Md.; and NASA's Goddard Institute for Space Studies in New York City shows this may not be the case at all. The work was supported by grants from the National Science Foundation.

Ford Cars Getting Greener On The Inside
May 26, 2009 09:44 AM - Jason Pelletier, Low Impact Living, Low Impact Living

Numerous studies have shown that 75%+ of the energy used by a car over its lifetime is consumed in the operation of the vehicle. But we shouldn’t forget about the other 25% of energy use or the environmental impacts that come with it - hazardous chemicals that off-gas when our cars sit in the sun, components that are difficult to recycle, and loads of plastics made from petrochemicals among them.

New technique could find water on Earth-like planets orbiting distant suns

Since the early 1990s astronomers have discovered more than 300 planets orbiting stars other than our sun, nearly all of them gas giants like Jupiter. Powerful space telescopes, such as the one that is central to NASA's recently launched Kepler Mission, will make it easier to spot much smaller rocky extrasolar planets, or exoplanets, more similar to Earth. But seen from dozens of light years away, an Earth-like exoplanet will appear in telescopes as little more than a "pale blue dot," the term coined by the late astronomer Carl Sagan to describe how Earth appeared in a 1990 photograph taken by the Voyager spacecraft from near the edge of the solar system. Using instruments aboard the Deep Impact spacecraft, a team of astronomers and astrobiologists has devised a technique to tell whether such a planet harbors liquid water, which in turn could tell whether it might be able to support life.

In Hot Pursuit of Fusion (or Folly)
May 26, 2009 06:53 AM - WILLIAM J. BROAD, The New York Times

Here in a dry California valley, outside a small town (Livermore), a cathedral of light is to be dedicated on Friday. Like the cathedrals of antiquity, it is built on an unrivaled scale with unmatched technology, and it embodies a scientific doctrine that, if confirmed, might lift civilization to new heights. "Bringing Star Power to Earth" reads a giant banner that was recently unfurled across a building the size of a football stadium.

Climate Change on Business Agenda in Denmark
May 24, 2009 07:35 AM - Reuters

Businesses leaders met in Denmark on Sunday to try to unite behind a call for long-term climate policies on oil, power and technology ahead of a U.N. conference in December that aims to replace the Kyoto Protocol. Many companies want new rules to help plan investment and capitalize on green technology. Some shareholders also want more climate-friendly business, but companies reliant on fossil fuels may lose out from measures to boost low-carbon alternatives.

Endangered North Atlantic Right Whales detected near Greenland

A group of endangered North Atlantic right whales has been identified near Greenland in an area where the species was thought to be extinct, using a system of underwater microphones.

Yosemite's giant trees disappear
May 23, 2009 07:31 AM - Matt Walker, Earth News

The oldest and largest trees within California's world famous Yosemite National Park are disappearing. Climate change appears to be a major cause of the loss. The revelation comes from an analysis of data collected over 60 years by forest ecologists.

Carbon capture success in Wisconsin
