A tax on beef isn't likely to achieve the intended outcome of reducing greenhouse gas emissions. Instead, it could create a spate of unintended consequences.
Canadians are a wasteful bunch, especially during the holidays. Redesign your holidays this year to cut back on garbage and food waste.
New experimental results on methane may help us to uncover whether Uranus really is the coldest planet.
Global greenhouse gas levels have hit their highest point in at least 3 million years, according to new figures from the World Meteorological Organisation.
Landfills produce huge amounts of methane. Many of the bigger operators capture it to turn into energy, but they’re wasting about 80% of what’s available. It’s time Australia stepped up.
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?
