The conservation lens
The definition of conservation priorities for biodiversity often focuses only on the numbers of vertebrate animals and seed plants in the northern hemisphere or in the tropics. view more (2007-10-25)
European lead in reading past climates from ice cores
Climate change is a reality today, but how can we find out about the future dangers it poses" What we really need is a full record of the Earth's climate for several hundred thousand years, complete with samples of air from different epochs that can be taken to the lab for analysis. view more (2007-10-12)
Ocean temperatures and sea level increases 50 percent higher than previously estimated
New research suggests that ocean temperature and associated sea level increases between 1961 and 2003 were 50 percent larger than estimated in the 2007 Intergovernmental Panel on Climate Change report. view more (2008-06-19)
Unlikely life thriving at Antarctica's Blood Falls
An unmapped reservoir of briny liquid chemically similar to sea water, but hidden under an inland Antarctic glacier, appears to support microbial life in a cold, dark, oxygen-poor environment -- a most unexpected setting to be teeming with life. view more (2009-04-20)
Climate swings have brought great CO2 pulses up from the deep sea
May 10, 2007, The Earth Institute at Columbia University—A study released today provides some of the first solid evidence that warming-induced changes in ocean circulation at the end of the last Ice Age caused vast quantities of ancient carbon dioxide to belch from the deep sea into the atmosphere. view more (2007-05-14)
Volcanic blast likely killed and preserved juvenile fossil plesiosaur found in Antarctica
Amid 70-mile-an-hour winds and freezing Antarctic conditions, an American-Argentine research team has recovered the well-preserved fossil skeleton of a juvenile plesiosaur-a marine reptile that swam the waters of the Southern Ocean roughly 70 million years ago. view more (2006-12-12)
NASA keeps eye on ozone layer amid Montreal Protocol's success
NASA scientists will join researchers from around the world to celebrate the 20th anniversary of the Montreal Protocol, an international treaty designed to reduce the hole in Earth's protective ozone layer. view more (2007-09-14)
By airship to the North Pole — Zeppelin expedition will survey sea ice in the Arctic
In 2008, scientists will, for the very first time, create a continual profile of ice thickness in the Artic, extending from the Canadian coast across the North Pole to Siberia. view more (2007-04-13)
UD researchers focus on building telescope at South Pole
It's 40 degrees F below zero (with the wind chill) at the South Pole today. Yet a research team from the University of Delaware is taking it all in stride. view more (2008-12-10)
2008 ozone hole larger than last year
The 2008 ozone hole - a thinning in the ozone layer over Antarctica - is larger both in size and ozone loss than 2007 but is not as large as 2006. view more (2008-10-08)
Great Lake's sinkholes host exotic ecosystems
Researchers are exploring extreme conditions for life in a place not known for extremes. As little as 20 meters (66 feet) below the surface of Lake Huron, the third largest of North America's Great Lakes, peculiar geological formations-sinkholes made by water dissolving parts of an ancient underlying seabed-harbor bizarre ecosystems where the fish... view more...

Half-baked asteroids have Earth-like crust
Asteroids are hunks of rock that orbit in the outer reaches of space, and scientists have generally assumed that their small size limited the types of rock that could form in their crusts. view more (2009-01-08)
Ocean warming on the rise
Increased scientific confidence that ocean observations are accurately reflecting rising global temperatures is central to new Australian research published today in the journal, Nature. view more (2008-06-19)
Some animals won't adapt to climate change
In a fascinating study appearing in the November issue of The American Naturalist, biologists investigated the response of small animals to climate change on a remote sub-Antarctic Island. view more (2006-11-14)
Hot spots for cool birds
Global research highlighting the most important areas for albatross migration and breeding may yet help save these magical birds from extinction. view more (2004-11-08)
Albatross study provides new information vital to their conservation
Albatrosses are the world's most threatened family of birds. New research offers the first hope of identifying migration and feeding patterns to reduce their unnecessary slaughter by long-line fisheries. The study is reported in the journal Science, and outlines, for the first time, the year-round habitat of the grey-headed albatross. view more (2005-01-11)
Scientists take off on historic mission to measure greenhouse gases that have an impact on climate
HIAPER, one of the nation's most advanced research aircraft, is scheduled to embark on an historic mission spanning the globe from the Arctic to the Antarctic. view more (2009-01-08)
Southern Ocean could slow global warming
The Southern Ocean may slow the rate of global warming by absorbing significantly more heat and carbon dioxide than previously thought, according to new research. view more (2006-12-06)
Patagonian glacier yields clues for improved understanding of global climate change
A better understanding of climate variations at planetary scale is one of climate scientists' crucial concerns. Stable water isotope analysis, the chemistry of ice cores taken from the Arctic and Antarctic polar ice caps and of air bubbles trapped in them now allow a chronology to be drawn up of the climate changes that took place over the past... view more...

Evolution: Crabs go deep to avoid hot water
Researchers from the National Oceanography Centre, Southampton, have drawn together 200 years' worth of oceanographic knowledge to investigate the distribution of a notorious deep-sea giant - the king crab. view more (2009-07-06)
