Political people in the United States are watching the chaos in Washington in the moment. But some people in the science community are watching the chaos somewhere else — the Arctic.

It’s polar night there now — the sun isn’t rising in much of the Arctic. That’s when the Arctic is supposed to get super-cold, when the sea ice that covers the vast Arctic Ocean is supposed to grow and thicken.

More than 1,000 early-career scientists from across Canada have written to Prime Minister Justin Trudeau and key members of his cabinet urging the government to do a better job of assessing the environmental impacts of developments.

The scientists say they are “concerned that current environmental assessments and regulatory decision-making processes lack scientific rigour,” and that the health of Canadians and the environment are being put at risk.

Global changes in temperature due to human-induced climate change have already impacted every aspect of life on Earth from genes to entire ecosystems, with increasingly unpredictable consequences for humans -- according to a new study published in the journal Science.

The study found a staggering 80 percent of 94 ecological processes that form the foundation for healthy marine, freshwater and terrestrial ecosystems already show signs of distress and response to climate change.

Climate change denier promises to bring in new era for coal, pull U.S. out of international climate commitments

Hours after the stunning U.S. presidential election returns showed an avowed climate change denier chosen for the nation's highest office, environmentalists around the world grappled with what a Donald Trump presidency will mean for the planet.

A massive chunk of ice – thought to be the largest iceberg to ever break off a glacier in Canada – fell into a lake in British Columbia this summer and no one noticed until a U.S. scientist saw it on a NASA photo.

Dr. Mauri Pelto, professor of environmental science at Nichols College in Massachusetts and director of the North Cascade Glacier Climate Project for more than 25 years, said the Porcupine Glacier retreated nearly two kilometres in one leap when the iceberg broke off.
