Dams nudge Amazon's eco-systems out of wack

Once upon a time, thousands of dorados, a giant among catfish, would swim more than 3000 kilometers from the mouth of the Amazon River to spawn in Bolivia's Mamoré River, in the foothills of the Andes. But the dorado, which can grow to more than 2 meters in length, is disappearing from those waters, and scientists blame two hydropower dams erected downstream a decade ago. As countries seek new energy sources to drive economic growth, a surge in dam construction on the eastern flank of the Andes could further threaten fish migration and sediment flows, scientists warn this week in Science Advances. The main consequence of proliferating dams is habitat fragmentation. The dorado's disappearance suggests fragmentation is already taking a toll.

If the world builds every coal plant that’s planned, climate change goals are doomed, scientists say

The Washington Post

The much-heralded demise of the coal industry may be overstated, a new scientific analysis asserts — finding that if all planned plants were constructed, the world would have little chance of meeting its climate change goals. Story here.

Revealed: Gaps in polar bear conservation in Canada

World Wildlife Fund

WWF’s first Polar Bear Scorecard found that Canada has shown leadership by investing in subpopulation monitoring. But two years into the 10-year, five-nation Circumpolar Action Plan for the Conservation of Polar Bears (CAP) it has not met its goals in identifying critical habitat nor in setting out best practices for tourism operators and for oil spill response.
