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 …
Rapid declines in summer Arctic sea ice extent are projected under high-forcing future climate scenarios. Regional Arctic climate engineering has been suggested as an emergency strategy to save the sea ice. Model simulations of idealized regional dimming experiments compared to a business-as-usual greenhouse gas emission simulation demonstrate the importance of …
Arctic winters may have got shorter by a month. Arctic lakes have been found to be freezing up later in the year and thawing earlier, creating a winter ice season about 24 days shorter than it was in 1950. Satellite imagery has also confirmed that climate change has dramatically affected …
The average temperature of Earth maintained its warming trend in 2013, despite seasonal and regional variations that included a shrinking ice cap in the Arctic and a massively growing one in the southern hemisphere, U.S. scientists said on Tuesday. NASA said the planet's average temperature in 2013 was 58.3 degrees …
The arctic blast that brought record low temperatures across the US in the past few days has provided fuel for global-warming sceptics, even as scientists debate whether the extreme cold might, in fact, be a consequence of a warming climate. "Of course, we can't say that this particular pattern is …
At a time when glaciers are melting at an alarming pace, an SOS buried in a bottle 54 years ago in the Canadian Arctic, and unearthed now, sent a distress signal about the world's rapidly disappearing glaciers. An American geologist Paul Walker, concerned about the melting of ice, buried a …
The year 2013 is currently on course to be among the top ten warmest years since modern records began in 1850, according to the World Meteorological Organization. The first nine months, January to September, tied with 2003 as the seventh warmest such period on record, with a global land and …
Two people injured in latest attack as hungry bears deprived of access to sea ice increasingly look for food on land A polar bear attack in Canada that left two people injured has brought new warnings from scientists of a dangerous rise in human-bear encounters in a warming Arctic. The …
A new scientific report shows that by moving rapidly to reduce pollutants such as methane and black carbon, could slow warming in critical snow and ice-covered regions while benefitting human welfare. Continued melting in snow and ice-covered regions will rise sea levels further, threaten water resources, and release more carbon …
A new report conducted by researchers at the University of Exeter offers insight into why Northwest Europe experienced extraordinarily wet summers between 2007 and 2012, stating that melting sea ice and changes with the jet stream are to blame for these soggier summers. Jet streams are currents of strong winds …
A landmark report from the world's top climate scientists this week is likely to say with heightened certainty that humans are behind the planet's rising temperatures, and that surface temperatures are not the only indicators of climate change. Senior scientist Kevin Trenberth of the National Center for Atmospheric Research in …
Black carbon - a presentation by Anumita Roychowdhury at CSE Annual South Asian Media Briefing Workshop on Climate Change, 2013 held in New Delhi from September 18-19, 2013.
A wide-ranging probe into woolly mammoths has added to evidence that the towering tusker was wiped out by climate change, scientists said on Wednesday. British and Swedish researchers sequenced DNA from 88 samples of mammoth bone, tooth and tusk, looking for a signature in the genetic code that is handed …
Shell has agreed to pay $1.1 million for air-quality violations from the vessels it used to drill two oil-exploration wells in Arctic waters off Alaska last year, federal regulators said. Shell will pay the civil fines for Clean Air Act violations that were discovered during inspections of the Discoverer and …
In a compelling survey, this report answers the question many are afraid to ask: is climate change already dangerous?This science survey measures the current manifestations and impacts of climate change against the "safe boundaries" metric; surveys the literature on tipping points and non-linear climate events; and provides a detail study …
MOSCOW: Greenpeace accused Russia on Monday of trying to block its protest against offshore drilling in the mineral-rich but ecologically fragile Arctic after Russian coastguards boarded its vessel. The environmental lobby group said Russian officials boarded its icebreaker after activists with banners reading "Save the Arctic" piloted motor boats toward …
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: The melting Arctic is now being called an “economic time bomb”. Economic modelling shows methane emissions caused by shrinking sea ice from just one area of the Arctic could come with a global price tag of $60 trillion — the size of the world economy in 2012. Researchers from …
During an 8 day drift in July–August 2012 in the Nansen Basin, all components of the energy budget of melting first-year sea ice were observed. Absorption of solar radiation by the ice and ponds was the largest source of energy to the ice at almost all times during the drift. …
Climate scientists have linked the massive snowstorms and bitter spring weather now being experienced across Britain and large parts of Europe and North America to the dramatic loss of Arctic sea ice. Both the extent and the volume of the sea ice that forms and melts each year in the …
Approximately 1700 Pg of soil carbon (C) are stored in the northern circumpolar permafrost zone, more than twice as much C than in the atmosphere. The overall amount, rate, and form of C released to the atmosphere in a warmer world will influence the strength of the permafrost C feedback …
