The steady loss of the kelp removes an important habitat for other species and has a cascading effect through the marine environment, a Halifax marine biologist warns.

Once rich forests of willowy kelp that stretch along Nova Scotia’s coast have been decimated by warming water temperatures, says a marine biologist who warns that the loss could harm other species that rely on them for food.

A cloud of noxious particles brewing in the air above the Alberta oil sands is one of the most prolific sources of air pollution in North America, often exceeding the total emissions from Canada’s largest city, federal scientists have discovered.

The finding marks the first time researchers have quantified the role of oil sands operations in generating secondary organic aerosols, a poorly understood class of pollutants that have been linked to a range of adverse health effects.

The number of climate refugees could increase dramatically in future. Researchers of the Max Planck Institute for Chemistry and the Cyprus Institute in Nicosia have calculated that the Middle East and North Africa could become so hot that human habitability is compromised. The goal of limiting global warming to less than two degrees Celsius, agreed at the recent UN climate summit in Paris, will not be sufficient to prevent this scenario.

What's turning northern forests into tinder? Biggest reason is climate change, but that’s not all

A sudden shift in the wind at a critical time of day was all it took to send a wildfire out of control through Fort McMurray, forcing more than 80,000 people out of their homes in what has become the biggest natural disaster in Canadian history.
