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 …
In the polar tropospheric boundary layer, reactive halogen species (RHS) are responsible for ozone depletion as well as the oxidation of elemental mercury and dimethyl sulphide. After polar sunrise, air masses enriched in reactive bromine cover areas of several million square kilometers. Still, the source and release mechanisms of halogens …
President Barack Obama announced on Wednesday plans for a broad expansion of offshore oil and gas drilling in an effort to win Republican support for new proposals to fight climate change. Obama, a Democrat, said his administration would consider new areas for drilling in the mid and south Atlantic and …
A US backed proposal to ban the international trade of polar bear skins, teeth and claws was defeated on Thursday at a UN wildlife meeting over concerns it would hurt indigenous economies and arguments the practice didn't pose a significant threat to the animals. The US argued at the 175-nation …
KOLKATA, 18 March: The ministry of Earth Sciences is sending a team to the Arctic region for conducting a study on climate change next week. The change of climate in the Arctic region will affect the monsoon pattern of India adversely which in turn will affect the food resources in …
Simon Tisdall The Sami people have an ethical relationship with nature They had shown notable ability to adapt to changing climate conditions Governments still resist the idea that Arctic indigenous peoples have something unique to contribute As global warming and habitat degradation accelerate, people indigenous to the Arctic circle say …
Remobilization to the atmosphere of only a small fraction of the methane held in East Siberian Arctic Shelf (ESAS) sediments could trigger abrupt climate warming, yet it is believed that sub-sea permafrost acts as a lid to keep this shallow methane reservoir in place. Here, we show that more than …
Every winter the Arctic ice cap is penned in by curved barriers of ice spanning the straits that lead out of the Arctic Ocean. Now it seems that some of these ice arches are failing to form. The resulting exodus of sea ice into the Atlantic and Pacific could affect …
The world this year suffered the fewest number of natural disasters in a decade, but floods, droughts and other extreme weather continued to account for most of the deaths and economic losses, according to a UN report released on Monday. There were 245 natural disasters recorded this year, down from …
This study by the Arctic Monitoring and Assessment Program estimates that the sea will rise by 0.5 to 1.5 meters by 2100, threatening coastal cities and flooding island nations. This is double the predicted rise estimated by the UN's Intergovernmental Panel on climate Change (IPCC) in 2007, which did not …
The IGBP Climate-Change Index brings together key indicators of global change: atmospheric carbon dioxide, temperature, sea level and sea ice. It will be released annually. To know more click on the following URL: http://www.igbp.net/page.php?pid=504
Climate change is transforming the Arctic so fast that many species could be gone within our lifetimes. But the important thing is to put human self-interest first, says Alun Anderson.
The Arctic is currently undergoing dramatic environmental transformations, but it remains largely unknown how these changes compare with long-term natural variability. Here we present a lake sediment sequence from the Canadian Arctic that records warm periods of the past 200,000 years, including the 20th century. This record provides a perspective …
2009 Sea Ice Outlook Summary Reports are based on statements from contributors to the 2009 Sea Ice Outlook and provides an initial retrospective review of the 2009 Sea Ice Outlook effort at both the pan-arctic and regional scale
Ottawa: The multiyear ice covering the Arctic Ocean has effectively vanished, a startling development that will make it easier to open up polar shipping routes, an Arctic expert has claimed. Vast sheets of impenetrable multiyear ice, which can reach up to 80m thick, have for centuries blocked the path of …
Washington, Oct. 20: Sediment cores from a small Arctic lake in Canada stretching back 200,000 years show unprecedented gains in global warming since 1950, indicating human activity is the likely cause, a study said. "The past few decades have been unique in the past 200,000 years in terms of the …
The Arctic sea will be ice-free in the summer within 20 years, shortening the global time frame on climate change by a decade, according to a new report released on Wednesday. Speaking at the Royal Academy of Arts, Peter Wadhams, one of the world
