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.
Set aside the politics. If by some miracle we turned off carbon emissions immediately, how would the climate respond?
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.
Methane concentrations in the atmosphere are growing at a faster rate than any time in the past 20 years.
The Obama administration wants to regulate methane leaks from oil and gas operations. Here's why we can't count on market forces to make it work.
To meet global climate change targets, agriculture needs an array of innovations and money to get farmers around the world to adopt new practices.
Coal seam gas may not be responsible for a flaming river in Queensland, but it still raises uncomfortable questions.
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.
Eating less meat isn't the only solution to reducing greenhouse gas emissions from livestock.
If we do find life on Mars, it will be difficult to prove that we didn't bring it there from Earth. An insider talks us through what's at stake.
Fossil fuel emissions are slowing, but another major climate problem is becoming clear: food production.
Methane is a stronger greenhouse gas than carbon dioxide, and Australia's coal mines are a major source.
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.
The greenhouse gases that cause climate change will take centre stage at the upcoming Paris climate talks. What are they and what are their effects?
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.
Using more accurate data, researchers find that waste disposal at methane-emitting landfills is two times greater than previous EPA estimates.
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.
