In the summer of 2001, I kayaked solo for 66 days down the Nahanni, Liard, and Mackenzie rivers in Canada’s Northwest Territories.

In 2011, Philadelphia’s city-owned water utility drew national attention when it began Green City, Clean Waters, a 25-year program to manage an increasing volume of stormwater by using mostly “green infrastructure,” such as rain gardens and porous pavements, which allows rain to soak into the ground rather than becoming runoff that pollutes rivers and creeks.

Warming global climate is changing the vegetation structure of forests in the far north. 

Methane-oxidizing bacteria could play a greater role than previously thought in preventing the release of climate-damaging methane from lakes, researchers from Bremen report. 

Food, feed, fiber, and bioenergy: The demand for agricultural raw materials is rising. 

Safeguarding places to hang ten and shoot the curl is an opportunity to simultaneously mitigate climate change, fuel tourism and help surrounding ecosystems, new research has shown.

The swift fox — known as Nóouhàh-Toka’na to the Aaniiih and Nakoda tribes — once roamed the Western plains from Texas to Canada, eating small rodents and insects. But their numbers swooned with the arrival of settlers, who plowed their grasslands and set poison baits for canine predators.

An international research team led by the Centre for Microbiology and Environmental Systems Science (CeMESS) at the University of Vienna has discovered that comammox bacteria, first identified by them in 2015, can grow using guanidine, a nitrogen-rich organic compound, as their sole energy and nitrogen source.

University of Missouri scientists are battling against an emerging enemy of human health: nanoplastics. Much smaller in size than the diameter of an average human hair, nanoplastics are invisible to the naked eye.

Warming loaded the dice for fire weather — hot, dry conditions that leave forests ripe for burning — in Canada and in part of the Amazon last year, according to a new report.
