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 ice cores can be used to reconstruct atmospheric CO2 concentrations, revealing significant changes during the Holocene epoch which started 11,000 years ago. Here, a highly resolved delta13C record is presented for the past 11,000 years from measurements on atmospheric CO2 trapped in an Antarctic ice core. These data are …
The ozone hole, which had caused serious environmental concerns, is shrinking and it could fully heal by the end of the century, bringing more rain to eastern Australia, scientists said on Wednesday. Matthew Tulley from Bureau of Meteorology in Melbourne said the hole is now healing because of climate protection …
A huge outback dust storm swept eastern Australia and blanketed Sydney on Wednesday, disrupting transport, forcing people indoors and stripping thousands of tonnes of valuable farmland topsoil. The dust blacked out the outback town of Broken Hill on Tuesday, forcing a zinc mine to shut down, and swept 1,167 km …
Scientists are surprised at how extensively coastal ice in Antarctica and Greenland is thinning, according to a study Wednesday that could help predict rising sea levels linked to climate change. Analysis of millions of NASA satellite laser images showed the biggest loss of ice was caused by glaciers speeding up …
SETH BORENSTEIN New satellite information shows that ice sheets in Greenland and western Antarctica continue to shrink faster than scientists thought and in some places are already in runaway melt mode. British scientists for the first time calculated changes in the height of the vulnerable but massive ice sheets and …
Quakes, volcanic eruptions, giant landslides and tsunamis may become more frequent as global warming changes the earth's crust, scientists said on Wednesday. Climate-linked geological changes may also trigger "methane burps," the release of a potent greenhouse gas, currently stored in solid form under melting permafrost and the seabed, in quantities …
R. PRASAD The link between the levels of atmospheric carbon dioxide and Antarctic ice sheets has been established in yet another study. The latest study published online in the journal Nature has found the formation of ice sheets was triggered when the atmospheric carbon dioxide levels fell below a threshold …
Feedbacks on climate change so far identified are predominantly positive, enhancing the rate of change. Loss of sea-ice, increase in desert areas, water vapour increase, loss of tropical rain forest and the restriction of significant areas of marine productivity to higher latitude (thus smaller geographical zones) all lead to an …
Washington: Researchers have found the ideal spot for an observatory. The search for the best spot has led to the discovery of what is thought to be the coldest, driest, calmest place on Earth
This new UNEP report warns that the pace and extent of climate change may exceed even the most sobering expectations voiced by IPCC fourth assessment report. It is based on findings of more than 400 major peer-reviewed scientific studies & research institutions over the last three years. Climate Change Science …
When nations made plans to save the ozone layer, they didn't factor in global warming. Quirin Schiermeier reports on how two environmental problems complicate each other.
Twenty-five years after it established Dakshin Gangotri, the first permanent research station in the South Polar region, India is all set to build the third such centre in Antarctica to take up cutting-edge research in various fields. The new station, tentatively named Bharti, is scheduled to be operational by 2012, …
The publication reviews a selection of transboundary governance systems from around the world tackling the issue of shared resources and environmental impacts affecting them. This publication examines the characteristics of successful transboundary resource management. Various cases of different shared resources, from water to fish to air, are described and their …
Ice cores extracted from the Antarctic ice sheet suggest that glacial conditions and the relationship between temperatures and atmospheric carbon dioxide concentrations have been constant over the last 800,000 years, but there is some evidence for a fluctuating severity of glacial periods mediated by previously unidentified mechanisms. Variable migration of …
Indian scientists, who have been monitoring fluctuations in the continental ice margin at the Western Schirmacher range in Antarctica, have found a recession of about 7 metres ice per decade
This latest report is on Arctic and the Antractic under assault from the impacts of rapidly accelerating climate change, from increased industrialisation; and from the unchecked consumption of our planet's resources. The Arctic and the Antarctic: two of the greatest wilderness areas on Earth, with ecosystems vital to the functioning …
The global sea level will only rise about 10 feet if the West Antarctic ice sheet collapses. While that may not sound so great to residents of coastal cities like New York or Los Angeles, it is only about half the previously predicted rise. Researchers led by Jonathan L. Bamber …
