Today’s Cool Canuck Research is actually about warming and it’s really not very cool at all.
University of Victoria students Andrew MacDougall and Chris Avis, along with climate scientist Andrew Weaver, say their model shows that thawing permafrost in the Arctic will accelerate the rate of global warming. Their study is in Nature Geoscience Letters. The University of Victoria explains:
Permafrost is permanently frozen soil, sediment or rock. It’s estimated that about 18.8 million sq km of northern soils hold about 1,700 billion tonnes of organic carbon, or frozen compost—the remains of plants and animals that have accumulated over thousands of years. That’s about four times more than all the carbon emitted by human activity in modern times, and twice as much than is currently in the atmosphere.

A group of scientists has released a report condemning a Carleton University professor who taught a course centred on the idea that climate change is not caused by human emissions.
Tom Harris taught Climate Change: An Earth Sciences Perspective to mostly second-year non-science students between 2009 and 2011.
The Committee for the Advancement of Scientific Skepticism says in its report entitled Climate Change Denial in the Classroom that Harris hosted speakers who argued that climate change is not caused by humans but hosted “no scientist speaking to the generally accepted consensus.”
