State of the climate in 2022: special supplement to the Bulletin of the American Meteorological Society

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 …

Antarctic bacteria hold key to life under ice

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. …

Microbes detected under Antarctic ice

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 Kills 680 Antarctic Whales, Below Target

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 …

Driller thriller: Antarctica's tumultuous past revealed

The future of Antarctica's ice is written in stone from 19 million years ago. Douglas Fox meets the geologists drilling into history.

Ice Bridge Holding Antarctic Ice Shelf Cracks Up

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 …

Clinton Urges Controls On Antarctic Tourism

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 …

Modelling West Antarctic ice sheet growth and collapse through the past five million years

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 …

Obliquity-paced Pliocene West Antarctic ice sheet oscillations

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 …

West-side story of Antarctic ice

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.

Polar changes

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 …

Drilling into Antarctic ice for lost world

Hunt On For 400,000-Year-Old Organisms Believed To Be Markedly Different From Life Forms On Earth It

ACCORDING TO REPORT

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 …

Alp-sized peaks found below Antarctic ice

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

Interhemispheric Atlantic seesaw response during the last deglaciation

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 …

Rocket with NASA global warming satellite crashes

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 …

Third Antarctica research station by 2011

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 …
