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 […]
New Scientist25 September 2010 AGGRESSIVE tree-felling on mount Kilimanjaro could be partly to blame for its vanishing ice cap. The ice on Kilimanjaro’s summit has shrunk to just 15 per cent of its extent in 1912, leading campaigners to hold it up as a symbol of climate change. But other factors are also at play. […]
By Marcela ValenteSep 19, 2010 BUENOS AIRES (Tierramérica) – Argentina’s glaciers, along with Chile’s the most extensive of South America, manifest the damage caused by climate change, while they also face threats from mining and major transportation infrastructure projects. A law to protect them has been postponed yet again. Glaciers are vast reserves of freshwater, […]
U.S. Department of the Interior, U.S. Geological SurveyReleased: 9/20/2010 4:00:00 PM WASHINGTON — Dust caused by human activities in the American desert Southwest is a contributing factor in speeding up the melting of snow and reducing runoff in the mountains of the Colorado River basin, according to a new study led by NASA and co-authored […]
