Center for Ocean Solutions report warns that, left unchecked, the Pacific Ocean faces threats that will render some coastal areas uninhabitable.

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.

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.

2008 U.S. Fossil Fuel CO2 Emissions See Biggest Drop in Nearly 30 Years

Sky-high fuel prices, declining energy use and a slumping economy gave the U.S. its largest annual decline in fossil fuel-based carbon dioxide (CO2) emissions since 1982, when emissions fell 5.3 percent. Energy-related CO2 emissions in 2008 fell 2.8 percent compared to the year before, according to preliminary data released today by the U.S. Energy Information Administration (EIA).

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.

Shellfish reefs are 'most imperilled sea habitat'
May 22, 2009 07:34 AM - Peter Aldhous, New Scientist

Globally, 85 per cent of reefs have been lost. Destructive fishing practices, disease and coastal development threaten many of the survivors. What sounds like an apocalyptic vision of the future for the world's tropical corals is in fact a chilling assessment of the current state of reefs built in cooler waters by oysters and other bivalve shellfish.
