Melting Alaskan permafrost releases dangerous mercury levels
Thawing permafrost in Alaska's Yukon River is releasing alarming amounts of mercury, posing a significant threat to local Indigenous communities.
In short:
- A new study reveals that melted permafrost is releasing more mercury than previously estimated, with serious implications for human health.
- The mercury release could potentially contaminate fish, a critical food source for Alaska Native peoples, though further research is needed.
- The study highlights the broader risks of climate change to both the environment and Indigenous cultures.

Why this matters:
Mercury poisoning is a severe health risk, especially for vulnerable populations like pregnant women and children. The loss of traditional food sources and cultural practices due to contamination could further harm Indigenous communities.

The lie of a cleaner oilsands
In May 2022 a tailings pond at Imperial’s Kearl Lake facility started leaking toxic waste into groundwater and outside its lease boundaries. But no one reported the leak to water users living downstream of the massive oilsands project for nine months.
In a nutshell:
Award-winning journalist, Andrew Nikiforuk, writing for The Tyee, lays out a damning, but all-too-familiar chronology of ongoing hydrocarbon spills in the Alberta Oil patch that go unreported and unregulated by a seemingly complicit Alberta Energy Regulator. Indigenous leaders, their food sources and drinking water contaminated, have expressed total distrust with the state of monitoring and reporting, repeatedly castigating the Alberta Energy Regulator as a “joke” or unaccountable.
Key quote:
“All trust with the Alberta government has been broken and has been broken for a long time. They can’t be trusted to oversee the mess,” Athabasca Chipewyan First Nation Chief Allan Adam told Parliament’s Standing Committee on Environment and Sustainable Development.
Big picture:
At one time the Alberta government and industry promised to control the proliferation of the mining waste stream with stiff regulations. But industry ignored 2009 rules to reduce the volume of tailing waste and then regulators abandoned them. Now government and industry propose to rid themselves of the tailings waste problem with the cheapest possible solution — by minimally treating wastewater by filtering it through petroleum coke (a bitumen byproduct) with the goal of releasing that water into the Athabasca River.

EPA tightens mercury emissions limits at coal power plants
The EPA is tightening rules that limit emissions of mercury and other harmful pollutants from coal-fired power plants. The proposal would lower emissions of toxic pollutants that can harm brain development of young children and contribute to health problems in adults.
