Caption by Holli Riebeek and Adam Voiland9 November 2010 Of all the pollution that fills our lungs on any given day, the most dangerous is the small stuff. Aerosol particle pollution—airborne solid particles and liquid droplets—comes in a range of sizes. Particles smaller than 2.5 micrometers pose the greatest risk to human health because they […]
By JUSTIN GILLISNovember 13, 2010 TASIILAQ, Greenland — With a tense pilot gripping the stick, the helicopter hovered above the water, a red speck of machinery lost in a wilderness of rock and ice. To the right, a great fjord stretched toward the sea, choked with icebergs. To the left loomed one of the immense […]
There have been significant changes in the water mass characteristics of the Beaufort Sea which may impact species distribution and primary production. The freshwater and heat content of the Beaufort gyre has significantly increased relative to the 1970s. The temperature increase has been related to a twofold increase in the temperature of the Atlantic water […]
Long-term records of sea surface temperature show a period of colder surface waters from the period 1945–1978, switching to a long period of warmer surface waters from 1978–2006. The zooplankton community composition and several fisheries time series (e.g. salmon marine survival and sablefish recruitment) are correlated with large-scale climate signals (i.e. El Niño Southern Oscillation […]
Return to previous Arctic conditions is unlikely Record temperatures across Canadian Arctic and Greenland, a reduced summer sea ice cover, record snow cover decreases and links to some Northern Hemisphere weather support this conclusion.

Caption by Michon ScottOctober 17, 2010 Starting from the western face of Kali Himal, the Imja Glacier flows through eastern Nepal, part of a glacier network that ultimately feeds the Ganges River. In the 1960s, melt water began collecting at the foot of the glacier, creating Imja Tsho. A 2009 study described this lake of […]
By Stephen Leonard12:36 PM Saturday Oct 9, 2010 Melting sea ice threatens the way of life of Greenland’s Inughuit people, who hunt whale and seal by kayak and dog sled. Living in the most northern permanently inhabited settlements in the world, the Inughuit people, or Polar Eskimos as they are often known, have eked out […]
Contact: Brian Laghi, laghib@nrtee-trnee.ca October 5, 2010 The physical effects of climate change on Canada in the next century could touch everything from human health and community infrastructure to water resources and even tourism and recreation activities, according to a newly-compiled presentation of scientific research published today. Called Degrees of Change, the diagram is the […]
Irvine, Calif., October 04, 2010 — Freshwater is flowing into Earth’s oceans in greater amounts every year, a team of researchers has found, thanks to more frequent and extreme storms linked to global warming. All told, 18 percent more water fed into the world’s oceans from rivers and melting polar ice sheets in 2006 than […]
By JOHN COLLINS RUDOLFSeptember 23, 2010, 8:12 am Few images in the climate change debate have stirred as much controversy as the storied “hockey stick” graph, which shows average temperatures in the northern hemisphere holding roughly steady for 900 years or so, until the 20th century, when they rise sharply. First unveiled in 1998 by […]
