This is the 33rd issuance of the annual assessment now known as State of the Climate, published in the Bulletin since 1996. As a supplement to the Bulletin, its foremost function is to document the status and trajectory of many components of the climate system. However, as a series, the …
Washington: Hidden in the bonechilling dark beneath an Antarctic glacier, a colony of strange bacteria is thriving. Scientists investigating the flow of blood-red water from beneath the glacier discovered the bacteria, which have survived for millions of years, living on sulfur and iron compounds, they report in the journal Science. …
An uncharted reservoir of briny liquid, buried under an inland Antarctic glacier, supports unusual microbial life in a place where life is unthinkable. After sampling the outflow from below Taylor Glacier of the East Antarctic Ice Sheet, researchers believe that microbes have adapted over the past 1.5 million years to …
Japan's whaling catch in its latest Antarctic hunt fell far short of its target after disruptions by anti-whaling activists, the Fisheries Agency said on Monday. Japan, which considers whaling to be a cherished cultural tradition, killed 679 minke whales despite plans to catch around 850. It caught just one fin …
An ice bridge which had apparently held a vast Antarctic ice shelf in place during recorded history shattered on Saturday and could herald a wider collapse linked to global warming, a leading scientist said. "It's amazing how the ice has ruptured. Two days ago it was intact," David Vaughan, a …
US Secretary of State Hillary Clinton on Monday urged tighter controls on cruise ships and tourists in Antarctica to prevent further environmental damage to the fragile region. Addressing an international meeting on both the Antarctic and the Arctic, Clinton said as tourism increases to Antarctica there must be more regulations …

The West Antarctic ice sheet (WAIS), with ice volume equivalent to approx5 m of sea level, has long been considered capable of past and future catastrophic collapse. Today, the ice sheet is fringed by vulnerable floating ice shelves that buttress the fast flow of inland ice streams. Grounding lines are …
Thirty years after oxygen isotope records from microfossils deposited in ocean sediments confirmed the hypothesis that variations in the Earth's orbital geometry control the ice ages, fundamental questions remain over the response of the Antarctic ice sheets to orbital cycles. Furthermore, an understanding of the behaviour of the marine-based West …
During the past five million years, the West Antarctic ice sheet has waxed and waned in size. A two-pronged reconstruction of that history provides clues to the ice sheet's future behaviour.
The fourth International Polar Year, which began in March 2007 and ends this March, is another example of countries coming together to contribute funds and expertise to basic research. Many countries have been independently studying the Poles. But a collaborative effort has become necessary as understanding the various changes brought …
Long live the emperor: Emperor penguins, the only penguin variety that breed during the harsh Antarctic winters, are headed towards extinction, said a research published in the journal Proceedings of the National Academy of Sciences. If climate change continues to melt ice at rates published in the last report of …
Experts Use Radar And Gravity Sensors To Make First Detailed Maps Of Subglacial Mountain Range Oslo: Jagged mountains the size of the Alps have been found entombed in Antarctica
The asynchronous relationship between millennial-scale temperature changes over Greenland and Antarctica during the last glacial period has led to the notion of a bipolar seesaw which acts to redistribute heat depending on the state of meridional overturning circulation within the Atlantic Ocean. Here we present new records from the South …
Vandenberg Air Force Base: A rocket carrying a NASA satellite crashed into the ocean near Antarctica after a failed launch on Tuesday, ending a USD 280 million mission to track global warming from space. The Taurus XL rocket carrying the Orbiting Carbon Observatory blasted off just before 2 am local …
CUDDALORE: The Centre is setting up a third research station, Bharathi, on the Antarctica at an estimated cost of Rs.140 crore, and it will become operational in 2011, Shailesh Nayak, Secretary, Union Ministry of Earth Sciences, said on Wednesday. Mr. Nayak, who visited the Centre of Advanced Study in Marine …
