Arctic sea ice extent for the month of July was the third lowest for that month in the satellite record, after 2007 and 2006. The average rate of melt in July 2009 was nearly identical to that of July 2007. A strong high-pressure system, similar to the atmospheric pattern that dominated the summer of […]
By David Ljunggren OTTAWA (Reuters) – Regions of Arctic tundra around the world are heating up very rapidly, releasing more greenhouse gases than predicted and boosting the process of global warming, a leading expert said on Wednesday. Professor Greg Henry of the University of British Columbia also said higher temperatures meant larger plants were starting […]
By Christopher Joyce When wildlife biologists visited a remote spot in Canada called Banks Island in the spring of 2004, they discovered thousands upon thousands of dead musk oxen. It took years to determine the cause. They called it “rain-on-snow” — the worst case of it ever documented. “Long story short, about 20,000 musk oxen […]
By Cameron Dueck on the Bering Sea The Canadian Arctic is facing another year of open water with the summer break-up of sea ice ahead of schedule in many key parts of the northern archipelago. The early break-up of ice underlines the growing impact of climate change in the Poles where temperatures have risen much […]
June 2009 compared to past Junes Compared to previous Junes, ice extent in June 2009 was extremely close to the last two years, falling within 30,000 square kilometers (12,000 square miles) of the June extent in 2007 and 2008. The long-term trend indicates a decline of 3.3% per decade, an average of 40,100 square kilometers […]
By Slim Allagui – Thu Jul 9, 2:13 am ET NUUK (AFP) – From his trawler that motors along the Nuuk fjord, fisherman Johannes Heilmann has watched helplessly in recent years as climate change takes its toll on Greenland. Global warming is occurring twice as fast in the Arctic as in the rest of the […]
By Deborah Zabarenko, Environment Correspondent WASHINGTON (Reuters) – Arctic sea ice has thinned dramatically since 2004, with the older, thicker ice giving way to a younger, thinner kind that melts in the northern summer, NASA scientists reported on Tuesday. Researchers have known for years that ice covering in the Arctic Sea has been shrinking […]
Increased melting of the large polar ice sheets contributes to the observed increase in sea level. Observations of the area of the Greenland ice sheet that has been at the melting point temperature at least one day during the summer period shows a 50% increase during the period 1979 to 20086 (see figure). The Greenland […]
ANCHORAGE, Alaska— Today, responding to a court-ordered deadline, the U.S. Fish and Wildlife Service released long-overdue reports documenting the status of polar bears and Pacific walrus in Alaska. The reports confirm that polar bears in Alaska are declining and that Pacific walrus are under threat. Both species are imperiled due to the loss of […]
Edmonton—University of Alberta researchers conducting a water study in the Mackenzie River Delta have found a dramatically higher delivery of mercury from the Mackenzie River to the Arctic Ocean than determined in previous studies. Researcher Jennifer Graydon analyzed water in the Mackenzie River as it flowed north into the Beaufort Sea. She collected samples for […]
