Is the polar bear’s life becoming even more perilous?

Life's tough for polar bears: climate is extreme, ice varies, food's scattered. Yet they persist

Is the polar bear’s life becoming even more perilous?I recently had several encounters with polar bears in the Canadian Arctic at Coningham Bay on Prince of Wales Island, along the Nunavut coast. We had been advised that bears sometimes frequented this interesting area because Beluga whales often came here to moult and feed, and they are a plentiful and reliable source of food…

Caves in Northern Canada provide a history of ancient permafrost

Geoscientist sheds new light on permafrost thaw in the geologic past and what it could mean for our future

Caves in Northern Canada provide a history of ancient permafrostGeoscientists have uncovered surprising results that reveal a complex history of ancient permafrost thaw – with implications for understanding the effects of permafrost thawing and climate change in the Canadian Arctic today. “Permafrost is really a geological expression of climate, so permafrost response to past periods of global warming is like a natural experiment for…

Why some oil and gas investment was doomed regardless of COVID-19

The Arctic, and all its alluring possibilities, is not part of the future as the energy and investment industries see it unfolding

Why some oil and gas investment was doomed regardless of COVID-19Toronto-Dominion Bank announced recently it won’t loan money toward any oil and gas or related development in the Arctic. While this may elicit joy from the woke anti-fossil-fuel global warmists, this was in reality a very easy decision for TD. So too will it be for others like investment banks, institutional investors, and financial entities…

How changes in ancient soil microbes could predict Arctic future

Changing balance of microorganisms in Arctic soil due to climate change could have widespread effects, according to new research

How changes in ancient soil microbes could predict Arctic futureMicrobial communities in Arctic permafrost changed drastically at the end of the last ice age – and the shift could happen again due to modern climate change, according to a new study by University of Alberta scientists. The researchers compared the microbial communities found in permafrost formed during the last ice age, at the end of…

Replacements for banned CFCs polluting Arctic: study

Researchers find degraded, toxic compounds from CFC replacements in ice core sample from summit of Devon Ice Cap

Replacements for banned CFCs polluting Arctic: studySubstances used to replace ozone-depleting chlorofluorocarbons (CFCs) may be as problematic as their predecessors, a new study shows. “The degradation products from these substances may be just as concerning as the original chemicals they were meant to replace,” said Alison Criscitiello, director of the University of Alberta’s Canadian Ice Core Lab. “We are seeing significant levels of…

Ottawa sleeps while Russia executes its Arctic strategy

Canada continues to lack an all season ice breaker fleet capable of operating in the Arctic Ocean

Ottawa sleeps while Russia executes its Arctic strategyAt the height of the cold war, the polar region was one of the centres of the superpower’s shadow war. Today, a rapidly melting polar ice cap is once again making the Arctic the nexus of a modern great power rivalry. Canada, whose long-standing territorial claims in the region date back to the various Hudson…
