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 […]
Reindeer and caribou numbers are plummeting around the world. By Matt Walker The first global review of their status has found that reindeer and caribou numbers are plummeting around the world. It is increasingly difficult for the deer to survive in a world warmed by climate change and altered by industrial development, say scientists. The […]
As the frozen soil in the Arctic thaws, bacteria will break down organic matter, releasing long-stored carbon into the warming atmosphere. At the same time, plants will proliferate, nurtured by balmier temperatures, more nutrients from decomposing soil and the increasing abundance of the greenhouse gas they depend on for growth. These connected but contrasting changes […]
I interviewed by email Dr. Mark Serreze, recently named director of The National Snow and Ice Data Center. Partly I wanted him to explain his “death spiral” metaphor for Arctic ice (see NSIDC: Arctic melt passes the point of no return, “We hate to say we told you so, but we did”). … CP: […]
The fish changed colour. New bird species were spotted. Two bridges were wiped out by a once-in-a-lifetime flood that forced villagers to dump sewage into their pristine waters. The locals have a message for city-dwellers: This is what climate change looks like. “Climate change is real,” says Ron Mongeau, the town manager of Pangnirtung, a […]
