By Jeffrey Jones, editing by Peter GallowayWed Dec 15, 4:53 pm ET CALGARY, Alberta (Reuters) – Reclamation in Canada’s oil sands is not keeping pace with rapid development and that could leave the public vulnerable to major financial burdens in years to come, a scientific panel said Wednesday. The study by Royal Society of Canada […]
By Jim Bouldin24 October 2010 Red foliage is one thing you’re not supposed to see a lot of in western North America, any time of year. In many places in the west–particularly through the central and northern Rocky Mountains and British Columbia–there is now a lot of red foliage, but unfortunately, it’s not just in […]
Sea surface and air temperature records for the Gulf of St. Lawrence. Sea surface temperature averages for the Gulf of St. Lawrence from May to November, from 1 km2 resolution NOAA AVHRR imagery, are available since 1985 (blue line) and show a 2ºC warming trend between a cooler and a warmer period centered around 1993. […]
Between 1979 and 2008, first-year sea ice in the summer has been declining at a rate of 8.7% per decade, whereas the thick multi-year sea ice in the summer is being lost at an average rate of 6.4% per decade and over 20% per decade in some areas of the Canadian Arctic Archipelago. This decreasing […]
Estimates of weight-at-age (g) for 3-6 year old herring from 1970 to 2008. There has been a significant change in the size of Pacific herring, a key forage species. Similar to that of the West Coast of Vancouver Island ecozone, a decline in the weight-at-age of Pacific herring occurred from 1970–2008. This decline is currently […]
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 […]
Pre-fishery biomass (in 1000s of tonnes) of Pacific herring in three subregions of the North Coast and Hecate Strait ecozone. The top left panel is for the Central Coast, the top right panel for Haida Gwaii, and the lower panel for the Prince Rupert District. The horizontal line represents the minimum spawning stock biomass. 2010 […]
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 […]
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 […]
By Bob Weber, The Canadian PressPublished Friday, Oct. 01, 2010 11:47PM EDT Edmonton — A study by Environment Canada indicates levels of toxic mercury in the eggs of water birds downstream from the oil-sands industry seem to have grown by nearly 50 per cent over the last three decades. The study, one of the few […]
