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 …
Thirty-five years ago, a scientist named John H Mercer issued a warning. By then it was already becoming clear that human emissions would warm the earth, and Dr Mercer had begun thinking deeply about the consequences. His paper, in the journal Nature, was titled "West Antarctic Ice Sheet and CO2 …
Worldwide, 2012 was among the 10 warmest years on record according to the 2012 State of the Climate report released by the American Meteorological Society (AMS). The peer-reviewed report, with scientists from NOAA’s National Climatic Data Center in Asheville, NC serving as lead editors, was compiled by 384 scientists from …
LONDON: Global warming five million years ago may have caused parts of Antarctica's large ice sheets to melt and sea levels to rise by approximately 20 metres, a new study has claimed. The researchers, from Imperial College London, and their academic partners studied mud samples to learn about ancient melting …
Global warming five million years ago may have caused parts of Antarctica’s large ice sheets to melt and sea levels to rise by approximately 20 metres, a new study has claimed. The researchers, from Imperial College London, and their academic partners studied mud samples to learn about ancient melting of …
A satellite has detected that 300 billion tonnes of ice is being lost every year from the Antarctic and Greenland glaciers, dramatically increasing sea levels around the world. The satellite that detected the melting is Gravity Recovery and Climate Experiment (GRACE). British scientists have been using it since 2002 to …
Each degree celsius rise in global temperatures is likely to raise world's sea levels by more than 2 metres within the next 2,000 years, a new study has warned. While thermal expansion of the ocean and melting mountain glaciers are the most important factors causing sea-level change today, the Greenland …
Even as global warming and climatic changes remain on the forefront of international debates, observations by the Geological Survey of India (GSI) have found a reduction in the rate of glacial snout as well as higher accumulation of snow on ice shelf and polar ice sheet at the India’s Antarctica …
Antarctic summer ice melt is now occurring 10 times faster than it did 600 years ago, with ice loss speeding up the most since mid-20th century, new research has warned. The 1000-year Antarctic Peninsula climate reconstruction was published in the journal Nature Geoscience. Summer ice melt affects the stability of …
Summer ice in the Antarctic is melting 10 times quicker than it was 600 years ago, with the most rapid melt occurring in the last 50 years, a joint Australian-British study showed Monday. A research team from the Australian National University and the British Antarctic Survey drilled a 364-metre (1,194 …
The ozone layer acts like a shield in safeguarding the Earth by preventing the harmful ultraviolet radiations from entering into the atmosphere. Reported damage to the ozone layer in 1985 was a significant milestone in Antarctic science research. The research work played a significant role in generating international socio-political debate …
Hunters have slaughtered 3,500 reindeer on a British island near Antarctica to try to get rid of the animals that were brought from Norway a century ago and are an increasing threat to native wildlife. The reindeer on South Georgia were corralled into pens and slaughtered by a 16-strong team, …
Antarctic marine ecosystems have undergone significant changes as a result of human activities in the past and are now responding in varied and often complicated ways to climate change impacts. Recent years have seen the emergence of large-scale mechanistic explanations–or “paradigms of change”–that attempt to synthesize our understanding of past …
Greenland is less vulnerable than expected to a runaway melt that would drive up world sea levels, according to scientists who found that only a quarter of the ice sheet thawed in a warm period more than 100,000 years ago. The study, involving 300 experts from 14 nations, implied that …
About 3,000 reindeer on an island near Antarctica are to be slaughtered to stop damage to the environment by the descendants of a tiny herd introduced a century ago for food by Norwegian whale hunters. A 16-strong team, mostly Sami reindeer herders, has arrived in South Georgia, a British overseas …
London: Rise in sea levels in the future due to the melting of the Greenland and Antarctic ice sheets could be substantially larger than IPCC estimates, according to a new first-of-its-kind study. Researchers from the University of Bristol found that the future rise in sea levels predicted by the Fourth …
Temperatures in the western part of Antarctica are rising almost twice as fast as previously believed, adding to fears that continued thaws are causing sea levels to rise, according to comprehensive research published this week. In a discovery that raises new concerns about the effects of climate change on the …
The West Antarctic Ice Sheet, whose melt currently contributes substantially to sea level rise each year, is warming twice as quickly as previously thought, a new study has found. The temperature record from Byrd Station, a scientific outpost in the centre of the West Antarctic Ice Sheet (WAIS), demonstrates a …
The West Antarctic Ice Sheet, whose melt may be responsible for 10 percent of the sea-level rise caused by climate change, is warming twice as quickly as previously thought, a study said on Sunday. A re-analysis of temperature records from 1958 to 2010 revealed an increase of 2.4 degrees Celsius …
Climate models predict that precipitation will increase in Antarctica, leading to potential ice mass gain and an offset to sea level rise, but here it is shown that enhanced snowfall on Antarctica is likely to increase ice discharge and thereby negate 30% to 65% of the snowfall-induced ice gain.
Evidence that global warming is man-made is getting stronger, the head of a U.N. panel of climate scientists said, in a further blow to skeptics who argue rising temperatures can be explained by natural variations. Rajendra Pachauri spoke on the sidelines of a conference in Qatar where 200 nations are …
