Bad weather is bad news, also for the red-listed kittiwake. New research reveals that wind conditions combined with the availability of different prey species are determinants of chick production in this seabird.
Researchers from the National Research Council Canada investigated why the Yukon River didnt freeze at the George Black ferry crossing, where the ice bridge is usually built, for the last two winters.
A new study links rapid deoxygenation in the Gulf of St. Lawrence to two powerful currents: the Gulf Stream and the Labrador Current.
The Gulf of St. Lawrence has warmed and lost oxygen faster than almost anywhere else in the global oceans due to large-scale climate change, raising the possibility the Gulf could soon be unable to support marine life, according to a new study.
Iqaluit is prepared to spend $566,000 on an emergency backup plan, but there's a risk it may never be used, says a city director.
Some scientists said the study, published in the journal Nature Communications, underscores the limitations and uncertainties of climate modeling – and how policymakers might need to take more aggressive steps if they want to keep global temperatures under control. Listen now
Climate change: the boreal forest will grow, then decline: The acceleration of growth will be fueled by warming in the north of the boreal forest, while the south (Abitibi, Lac-Saint-Jean, Gaspésie) will suffer from a lack of water.
Climate change is causing more severe flooding around the country, and a disproportionate number of Native American communities are on the front lines.
A team of biologists is surveying a lake on Kodiak Island for crawfish, an invasive species in Alaska that has been observed in higher frequency over past several years.
Thirty-five people drowned in Sweden this July, compared to 12 people who lost their lives to drowning last July.
Sixteen water bodies were added to this week's list.
EUMETSAT satellite shows blue-green algae bloom covering Lake Okeechobee.
Harmful algae blooms are something Montana has to worry about every summer, and now there have been a couple places in central and western Montana confirmed to have the harmful blue green algae. T...
From floods to fires, drought to coastal erosion, climate change is already having an impact on Canada's communities, landscapes and wildlife
Blue-green algae has bloomed again in Lake Okeechobee, filling waterways with putrid sludge that can contaminate local water and marine animals.
Water quality in Anchorage's lakes is generally good, but swimmer's itch is a risk.
The combination of abundant rain and snowfall and extremely warm mean annual air temperatures may have led to the destabilization of permafrost around lake margins. Rapid snow melt and high amounts of excess meltwater further promoted rapid lateral breaching at lake shores and consequently sudden drainage of some of the largest lakes of the study region.
An oxygen-starved area of almost 165,000 square kilometres in the Gulf of Oman is now the world’s largest marine “dead zone.” Incapable of supporting
The initial results represent 330 participants from six communities. Around 98 per cent of participants had mercury levels below the health guidance value - a baseline to assess health risks.
Average number of days with heavy rain or snow across Canada has been outside norm since spring 2013
