Protecting the Arctic from rapid warming is one of the essential steps in averting runaway climate change for the entire planet, Inuit leader Sheila Watt-Cloutier states in an opinion piece for the Globe and Mail.

Rapid ice loss is already having a devastating impact in the world’s Arctic and Antarctic regions. And in an explainer on the implications of an ice-free Arctic, CBC stresses that what happens in the polar region doesn’t stay there.

The 23-kilometre land link that connects Nova Scotia to the rest of Canada is at risk as climate change drives up sea levels and makes severe storms more frequent.

The world’s oceans will rise nearly one metre (three feet) by 2100, 100-year coastal storms and flooding will happen annually, fish stocks will see serious declines, snow and ice cover will diminish, and killer storms will get wetter and more powerful without fast action to reduce the greenhouse gas emissions that cause climate change, concludes ...

The world’s leading international climate science agencies are predicting 2.9 to 3.4°C average global warming by 2100 based on governments’ current climate commitments, “a shift likely to bring catastrophic change across the globe,” The Guardian reports.

A steady stream of hurricane-force storms has Atlantic Canada rethinking its approach to electricity grids, shoreline defences, and even tree planting, while insurance companies brace themselves for damage claims that are set to double every five to seven years.

Rising sea levels and catastrophic storm surges could displace 280 million people from the world’s coastlines and produce “misery on a global scale” unless countries speed up their efforts to control the greenhouse gas emissions responsible for the climate crisis, according to a draft United Nations report obtained last week by Agence France-Presse.

Wildfires across northern Canada are “mining” carbon from the soil and turning the boreal forest into a carbon source after millennia of acting as a carbon sink, in a process that could accelerate global climate change, according to a new paper in the journal Nature.

Increased greenhouse gas emissions may drive up atmospheric temperatures by as much as 35% more than climate scientists previously believed, according to more than a half-dozen of the new climate models that will inform the next major assessment from the Intergovernmental Panel on Climate Change (IPCC).

Climate change is a “deciding factor” in this summer’s record high water levels on the Great Lakes, CTV News reported earlier this month, citing climate adaptation specialist Blair Feltmate of the University of Waterloo.

The Canadian Paediatric Society and the Ontario Public Health Association are both out with new warnings about the impacts of climate change on children’s health.

Alberta bird populations have declined dramatically over the last 50 years, and a Calgary naturalist and citizen scientist is blaming a combination of human activity and climate change.

The frequency of major climate disasters has reached one per week around the world, a top United Nations official warns, in a new report that calls for developing countries to prepare now for the “profound impact” they will continue to face.

Buildings, coastlines, and Northern communities in Canada face the most serious risks from climate change, according to a new report produced for the federal Treasury Board by the Council of Canadian Academies.

The impacts of climate change could cost the global economy US$69 trillion through 2100 if average global warming is allowed to hit 2.0°C, according to a new study by consultants at Moody’s Analytics.
