Climate change likely to make it harder to feed 1 billion hungry: CIDA chief

Canadian Press: Poor countries are still gripped by the food crisis of two years ago and climate change will only make things tougher in the coming years, says the head of Canadian International Development Agency. CIDA President Margaret Biggs offered that candid assessment of the state of the undeveloped world and what Canada can to do help, in a speech Thursday to University of Ottawa students. Biggs, who rarely speaks publicly, also said a tough road lies ahead in rebuilding ...

Defusing the Methane Greenhouse Time Bomb

Scientific American: Methane trapped in Arctic ice (and elsewhere) could be rapidly released into the atmosphere as a result of global warming in a possible doomsday scenario for climate change, some scientists worry. After all, methane is 72 times more powerful as a greenhouse gas than carbon dioxide over a 20-year timescale. But research announced at the annual meeting of the American Geophysical Union this December suggests that marine microbes could at least partially defeat the methane "time bomb" sitting ...

Arctic melt to cost up to $24 trillion by 2050: report

Reuters: Arctic ice melting could cost global agriculture, real estate and insurance anywhere from $2.4 trillion to $24 trillion by 2050 in damage from rising sea levels, floods and heat waves, according to a report released on Friday. "Everybody around the world is going to bear these costs," said Eban Goodstein, a resource economist at Bard College in New York state who co-authored the report, called "Arctic Treasure, Global Assets Melting Away." He said the report, reviewed by more ...

Arctic climate changing faster than expected

Reuters: Climate change is transforming the Arctic environment faster than expected and accelerating the disappearance of sea ice, scientists said on Friday in giving their early findings from the biggest-ever study of Canada's changing north. The research project involved more than 370 scientists from 27 countries who collectively spent 15 months, starting in June 2007, aboard a research vessel above the Arctic Circle. It marked the first time a ship has stayed mobile in Canada's high Arctic ...

Bluefin tuna international trade ban proposal backed by UN agency

Guardian: A UN scientific agency today backed a proposal to ban international trade in Atlantic bluefin tuna, saying the species prized by sushi lovers needed to recover from commercial overfishing. Monaco had proposed protecting bluefin tuna, which can fetch up to $100,000 (£64,000) in Japan, by listing it under appendix I of the Convention on International Trade in Endangered Species (Cites). "In our opinion, international commercial trade in bluefin tuna should be prohibited," said ...

United States: The battle for Cape Wind

Living on Earth: YOUNG: It's Living on Earth, I'm Jeff Young. For wind energy enthusiasts, Cape Wind in Massachusetts is probably the most famous and frustrating proposal in the U.S. What could be the country's first offshore wind farm has been without a permit for construction for nine years--blocked by those who want to protect the ocean view off Cape Cod. U.S. Interior Department Secretary Ken Salazar wants an end to the delay. He recently boarded a boat to go see the Cape Wind site and hear from both ...

Arctic warming will cost world billions: Pew study

CBC: Climate warming in the Arctic will cost the global economy billions of dollars in 2010 alone, according to a study by the U.S.-based Pew Environment Group released Friday. The environmental advocacy organization held a news conference in Iqaluit -- where G7 finance ministers and central bank governors are meeting to discuss global economic reform -- to emphasize its view that protection of the environment should also be on the agenda. A study by the Pew Environment Group ...

Arctic ice melting faster than feared: study

CBC: The head of the largest climate change study ever undertaken in Canada says the Arctic sea ice is thinning faster than expected. "It's happening much faster than our most pessimistic projections," said University of Manitoba Prof. David Barber, the lead investigator of the Circumpolar Flaw Lead study. A flaw lead is the term for open water between pack ice and coastal ice. The study aboard the Canadian Coast Guard research ship Amundsen began in July 2007 and involved 370 ...

Scant Arctic ice could mean summer ‘double whammy.’

Reuters: Scant ice over the Arctic Sea this winter could mean a "double whammy" of powerful ice-melt next summer, a top U.S. climate scientist said on Thursday. "It's not that the ice keeps melting, it's just not growing very fast," said Mark Serreze, director of the U.S. National Snow and Ice Data Center. In January, Arctic sea ice grew by about 13,000 square miles (34,000 sq km) a day, which is a bit more than one-third the pace of ice growth during the 1980s, and less than the ...

Seals are hot at chilly G7 Canadian Arctic meeting

Reuters: Seals are hot at the G7 meeting in Canada's Arctic this weekend, whether it's the sealskin mitts artisans are trying to sell, or the raw seal meat on the menu at a community feast on Saturday. But officials and locals insist that hunting here is an essential livelihood for a community that already faces high prices for basic goods. Iqaluit, a town of 6,000 some 200 miles south of the Arctic Circle, is only accessible by air in winter, when Frobisher Bay freezes into a jagged shoreline ...
