Canadians love to paddle on them and camp beside them, but our boreal lakes offer more than just peace and beauty. They could provide clues to how life on Earth began.
While the gases most responsible for global warming - carbon dioxide, methane and nitrous oxide - continue to climb, other industrial greenhouse gases are being brought gradually under control.
Why use satellites to study Earth’s climate? Researchers leading a new mission explain how images from space will help them analyze which parts of the Americas soak up the most carbon.
Eating meat means greenhouse emissions. But the emissions from growing crops may have been underestimated, meaning that a climate-friendly diet isn’t as straightforward as simply going vegetarian.
The Aliso Canyon methane leak in California is bad, but it’s only a small portion of the methane leaked from the natural gas industry’s sprawling pipeline and storage infrastructure.
Scientists are studying how carbon-rich permafrost known as yedoma acts much like frozen vegetables to hungry microbes – and is becoming an additional source of heat-trapping gases.
The recent Lancet Commission report rightly pointed out that climate change is a huge risk to global public health. But it shied away from one of the main issues: the world consumes far too much meat.
About 10% of human-generated greenhouse gas emissions come from farming. Researchers are working on ways to address this piece of the global warming puzzle.
Meat uses a lot of resources - between three and ten times as much as plants for the same amount of protein. The rich world might be slowly losing its taste for meat, but the developing world isn’t.
