The most populous region of the biggest polluter on Earth – China’s northern plain – will become uninhabitable in places if climate change is not curbed. Story here.
Energy giant TransAlta paid the University of Alberta $54,000 to hand-pick one of its researchers to produce a study and other materials it used to lobby the provincial government to try to protect the coal industry, documents obtained by CBC News reveal. Story here.
Scientists studying the troposphere—the lowest level of the atmosphere—have found "powerful evidence" that climate change is altering seasonal temperatures. More here.

With warm weather, a high snowpack and floodwaters rising throughout the province, it may seem like B.C. is set to repeat last year’s weather patterns, which led to a catastrophic summer of fires. But it’s still too early to reliably predict…. More here.

The American oil and gas industry is leaking more methane than the government thinks — much more, a new study says. Since methane is a powerful greenhouse gas, that is bad news for climate change. More here.

The Antarctic Ice Sheet lost about 3 trillion tonnes of ice between 1992 and 2017. This figure corresponds to a mean sea-level rise of about 8 millimetres. While it could take a thousand years for a total "meltdown," all of Antarctica’s ice sheets, contain enough water to raise global sea level by 58 metres. So they're a key indicator of climate change and driver of sea-level rise. See video, below.

In the past decade methane levels have shot up, to the extent that the atmosphere contains two-and-a-half times as much of the gas as it did before the Industrial Revolution. More here.

The walls of this immense Siberian crater are more than 85 meters tall in places. Batagaika Crater has formed as rising temperatures have thawed the permafrost in Siberia. Warmer summers and shorter winters are causing the frozen layer cake of ice and soil to collapse (or “slump”) and erode away in much of the Arctic.

The “Atlantification” and “Pacification” of the Arctic has begun. As warmer waters stream into an increasingly ice-free Arctic Ocean, new species — from phytoplankton to whales — have the potential to upend this sensitive polar environment. More here.
The warmer weather of spring and summer means the start of tick and mosquito season and the diseases they transmit, including Lyme disease, Rocky Mountain spotted fever, West Nile and Zika. More here.

Large portions of Canada’s vast boreal forest could be at risk of dying off by the end of the century, as climate change will dramatically aggravate the risk of wildfires, drought and insect infestations, say government scientists in a groundbreaking new study. More here.
