On the Richter scale, the earthquake reached a magnitude of 7.3 at a place called Forbidden Plateau. Seventy-five years later, it still holds the title as the most powerful onshore quake ever recorded in Canada. In nearby communities, brick walls fell and three-quarters of all chimneys collapsed. Two casualties were recorded that day: one man died of heart failure and another drowned after his dinghy was overturned by a wave generated when a piece of land gave way and thundered into the sea. For a while, that seemed like the end of the story. But over time, the changes wrought by the quake revealed a mystery that had lain hidden for generations long enough t

Climate change, overfishing threatens food security in poorer countries: study

TORONTO A new study has found that the effects of climate change combined with overfishing pose an increasing threat to food security, particularly in poorer countries. The international team of researchers published their findings Tuesday in the journal Current Biology, analyzing over 800 species of fish in 157 countries. For billions around the world, fish offer an important source of micronutrients such as iron, zinc, vitamin A and omega 3. But fish are disappearing from parts of the world that rely on them to feed their population. Some of this has to do with foreign fishing boats that sell their catches elsewhere, says Aaron MacNeil, professor of biology at Dalhousie University in Halifax and one of the co-authors of the study.

How will Canada prepare for more heat waves and other extreme weather events?

How will Canada prepare for more heat waves and other extreme weather events? David Lao © THE CANADIAN PRESS/Jason Franson A flare stack lights the sky from the Imperial Oil refinery in Edmonton on December 28, 2018. A new climate change think tank funded by the federal government says Canadians should expect to face the harsh realities of a changing climate even under the most aggressive global efforts to curb fossil fuel use and cut greenhouse gas emissions. THE CANADIAN PRESS/Jason Franson As large swathes of the Western U.S. and central Canada continue to grapple with blistering heat, several climate and environmental safety experts are calling on governments and communities on all levels to double down on mitigation and adaption efforts to the inevitable effects of climate change.
