Influence of Patagonian glaciers on Antarctic dust deposition during the last glacial period

first_imgIce cores provide a record of changes in dust flux to Antarctica, which is thought to reflect changes in atmospheric circulation and environmental conditions in dust source areas(1-9). Isotopic tracers suggest that South America is the dominant source of the dust(10-12), but it is unclear what led to the variable deposition of dust at concentrations 20-50 times higher than present in glacial-aged ice(8,9). Here we characterize the age and composition of Patagonian glacial outwash sediments, to assess the relationship between the Antarctic dust record from Dome C (refs 9, 13) and Patagonian glacial fluctuations(14-16) for the past 80,000 years. We show that dust peaks in Antarctica coincide with periods in Patagonia when rivers of glacial meltwater deposited sediment directly onto easily mobilized outwash plains. No dust peaks were noted when the glaciers instead terminated directly into pro-glacial lakes. We thus propose that the variable sediment supply resulting from Patagonian glacial fluctuations may have acted as an on/off switch for Antarctic dust deposition. At the last glacial termination, Patagonian glaciers quickly retreated into lakes, which may help explain why the deglacial decline in Antarctic dust concentrations preceded the main phase of warming, sea-level rise and reduction in Southern Hemisphere sea-ice extent(13).last_img read more

Man who got Super Bowl tickets with Team Gleason’s help dies in van fire on way to game

first_imgIn 2011, Gleason was diagnosed with amyotrophic lateral sclerosis, or ALS, a degenerative neuromuscular disease.Since then he founded the Team Gleason Foundation to advocate for those living with the disease, and to assist in research. Earlier this year, Gleason earned the Congressional Gold Medal for his efforts. The Shelby, N.C., man had contacted Team Gleason for help in obtaining seats that were compliant with the Americans with Disabilities Act.Cushman and his older brother, Robert, were driving on Interstate 85 in Georgia when smoke began pouring out from beneath the vehicle. When Robert pulled over to check on the source, the van erupted in flames. He was unable to rescue his wheelchair-bound brother.“Words cannot express how shocked we are for Ed and his entire family,” the Gleason Foundation wrote in a statement. “We remain committed to our ALS community and Ed’s family in this time of incredible sadness.”Gleason played seven seasons for the Saints as a safety, and is best remembered for blocking a punt in the team’s first home game after Hurricane Katrina. A statue of Gleason outside the Mercedes-Benz Superdome, Rebirth, commemorates the moment. Former Saints player Steve Gleason’s Team Gleason helped a man with ALS get Super Bowl tickets, but what should have been a heartwarming story ended in tragedy when the man died en route to the game.According to TheAdvocate.com, 39-year-old Ed Cushman was killed Saturday when the van he was riding in caught on fire.last_img read more

Province and BC Cattlemens to investigate how livestock can help prevent forest

first_imgVICTORIA, B.C. – The Province of B.C. will provide the B.C. Cattlemen’s Association with $500,000 to investigate using grazing livestock to help prevent forest fires.“Using cattle and livestock grazing minimizes the growth of annual and perennial grasses, which helps to reduce wildfire risks,” said Doug Donaldson, Minister of Forests, Lands, Natural Resource Operations and Rural Development. “It’s one example of what we’re doing to reduce the threat of wildfires, while supporting the ranching sector and maintaining wildlife habitat in our province.”The Province will be working with local governments, the ranching sector and Indigenous communities to develop partnerships and provide opportunities for livestock owners, stakeholders and other interested parties. “Reducing the risk of wildfires and adapting to a changing climate requires more action than the status quo of the last 20 years,” said Lana Popham, Minister of Agriculture. “B.C.’s beef producers are well known for raising high-quality grass- and range-fed beef, and we’re working with them to find ways to combine that practice with reducing vegetation that fuels wildfires. It’s an intriguing model that I’m hopeful will become a mainstay in our efforts to protect our communities and resources from fires, as well as supporting B.C. ranchers and B.C. beef.”While targeted grazing using livestock is not a solution to all fuel management challenges, it is a powerful tool when used in combination with other methods, such as prescribed burning and selective tree harvesting.Wildfire prevention programs in southern Europe and parts of the U.S. are successfully using livestock to graze fuel breaks around communities and reduce the risk of wildfires.“The last two fire seasons have seen unprecedented resources burn in the province,” said Kevin Boon, general manager of the BC Cattlemen’s Association. “These events have shown us the value of agriculture, specifically cattle grazing, in mitigating the start or spread of fires while assisting in firefighting efforts. Cattle grazing reduces the fine fuels available for fires to take hold. This funding will allow us to develop partnerships in interface areas to help protect our lands, forests and communities, while producing some of the best quality food in the world.”Using livestock grazing to reduce the amount of herbaceous fine fuels in an area is a low carbon, cost-effective method that supports local food production and provides new opportunities for ranchers.last_img read more

RBI buys $5 bn through forex swap auction

first_imgMumbai: The Reserve Bank of India (RBI) Tuesday bought $5 billion through long-term forex swap auction in a bid to ease liquidity ahead of elections. RBI successfully concluded the forex swap auction, buying the targeted $5 billion as part of the long term dollar/rupee swap with a three-year tenor, it said in a statement. In turn, Rs 34,561 crore was infused into the Indian banking system. The RBI said it received $16.31 billion in bids for the auction for which the cut-off was set at 776 paise. Also Read – Thermal coal import may surpass 200 MT this fiscalThe central bank accepted $5.02 billion of dollars tendered. This formed part of RBI’s announcement earlier this month that it would buy dollars from banks for three years and offer them rupees in return. The swap will bulk up India’s foreign exchange reserves while injecting liquidity into the financial system to ease a cash crunch typically seen before the beginning of a financial year. It is meant to give RBI greater flexibility in managing banking system cash while helping soak up any potential large dollar inflows, such as from the Rs 42,000 crore purchase of Essar Steel by ArcelorMittal which could make the rupee rise sharply. India’s new fiscal year begins on April 1. The central bank has bought Rs 3 lakh crore of bonds this fiscal to support the market at a time when a record $100 billion borrowing plan of the government had cooled demand for debt.last_img read more

AMMK wants EC to allow agents 24×7 in EVM centres till counting day

first_imgChennai: The Amma Makkal Munnetra Kazhagam (AMMK) headed by TTV Dhinakaran Monday urged the Election Commission to allow agents of political parties to stay round-the-clock at centres where EVMs used in the April 18 Lok Sabha elections in Tamil Nadu are stored.

But it is a month-long wait (for May 23). We are okay with efforts taken by the EC, but its implementation lies with officials of state government,” he said.
