Peace River Break a Critical Conservation Corridor in Rare Intact Mountain Ecosystem

By Tim Burkhart, former researcher with the Cohen Commission and Peace River Break Coordinator with the Yellowstone to Yukon Conservation Initiative.
 
On a clear day after the thaw, I climb a meandering hiking trail through thick forest, crossing springs swollen with alpine melt, and scramble up rocky slopes to a wind-swept vista of alpine tundra at the weather-beaten peak of Mount Bickford, about 40 minutes west of the small industry town of Chetwynd, B.C.
 
From this lofty vantage point above the Pine Pass, the crucial east-west length of Highway 97 is visible, connecting northeast B.C. with the rest of the province west of the Rockies.
 
Standing beside the dark waters of a mountain lake, still fringed with snow, I can gaze out upon an uninterrupted view of one of the most important landscapes in British Columbia.

New 'Meta' Study Confirms Consensus: 97% of Publishing Climate Scientists Agree We are Causing Global Warming

By John Cook, The University of Queensland

When we published a paper in 2013 finding 97% scientific consensus on human-caused global warming, what surprised me was how surprised everyone was.

Ours wasn’t the first study to find such a scientific consensus. Nor was it the second. Nor were we the last.

Nevertheless, no-one I spoke to was aware of the existing research into such a consensus. Rather, the public thought there was a 50:50 debate among scientists on the basic question of whether human activity was causing global warming.

Burning Fossil Fuels is Responsible for Most Sea-Level Rise Since 1970

By Aimée Slangen, Utrecht University and John Church, CSIRO

Global average sea level has risen by about 17 cm between 1900 and 2005. This is a much faster rate than in the previous 3,000 years.

The sea level changes for several reasons, including rising temperatures as fossil fuel burning increases the amount of greenhouse gases in the atmosphere. In a warming climate, the seas are expected to rise at faster rates, increasing the risk of flooding along our coasts. But until now we didn’t know what fraction of the rise was the result of human activities.

In research published in Nature Climate Change, we show for the first time that the burning of fossil fuels is responsible for the majority of sea level rise since the late 20th century.

As the amount of greenhouse gases we are putting into the atmosphere continues to increase, we need to understand how sea level responds. This knowledge can be used to help predict future sea level changes.

Fact Check: Outlook for Coal Not Quite What it Used to Be

Coal pollution in China

This is a guest post by Benjamin Thibault and Andrew Read of the Pembina Institute

Coal Association of Canada (CAC) president, Robin Campbell is currently touring Alberta with a series of “ACT information meetings.” He is making a number of assertions about the province’s coal industry and Alberta’s Climate Leadership Plan. We feel that some of the points being raised by Campbell need to be addressed. This is the second blog post to address those claims and to reiterate the importance of Alberta’s pledge to phase out coal power pollution.
 
As our first fact check showed, the CAC has been disseminating some misinformation on coal’s contribution to air pollution in Alberta. Another bucket of inaccuracies centres around the long-term future of coal — both locally and internationally — and the potential for coal with carbon capture and storage (CCS) in particular.

Fact Checking the Coal Industry’s 'Information Meetings' in Alberta

This is a guest post by Benjamin Thibault and Andrew Read of the Pembina Institute

These are not good days for the global coal industry. There is bad news at every turn, with countless reports of “sputtering” and even falling demand.

Alberta has been a bastion for coal use in Canada. For now, the province burns more coal for electricity than all other provinces combined. But the writing has been on the wall for some time; over the long run, dirty coal-fired electricity is not compatible with credible climate change reduction strategies or with the public demand for cleaner air. These are the realities behind the province’s commitment to improve Alberta’s air quality and climate reputation by phasing out coal power pollution by 2030.

It is within this context that the Coal Association of Canada (CAC) is touring Alberta with “ACT information meetings.” But the “information” simply does not reflect coal’s stark modern reality. Let’s do some fact checking.

Four Reasons for Optimism On Vancouver Climate Declaration

Prime minister Justin Trudeau

This is a guest post by Clare Demerse of Clean Energy Canada.

Canada’s premiers and prime minister headed home from Vancouver last week having launched a brand-new climate change negotiation process. Set against a backdrop of clean tech power brokers and pipeline skirmishes, the lead-up to last week’s meeting generated headlines mainly for the faultlines it brought to the surface.

No doubt about it: Tough conversations are coming, especially about the best way to price carbon pollution. But as the hot rhetoric cools down, here are four reasons for optimism based on the results of last week’s First Ministers’ meeting.
