Beefy problem: livestock emit methane, but the soils where they graze can be much more climate-friendly than cropland.

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.
Livestock ‘digestion’ produces nearly 3 billion tonnes of greenhouse gases each year.

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.
Rice cultivation is one of the ways food production pumps methane into the atmosphere.

Fossil fuel emissions are slowing, but another major climate problem is becoming clear: food production.
An open-cut coal mine in the Hunter Valley.
Methane is a stronger greenhouse gas than carbon dioxide, and Australia's coal mines are a major source.
Looking for relief: Southern California Gas Company and outside experts work on a relief well at the Aliso Canyon designed to stop the ongoing natural gas leak.
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?
Carbon in some types of ancient permafrost is digested by greenhouse gas-producing microbes.

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.
Worldwide, the livestock industry is a bigger source of greenhouse gases than transport.

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.
How to trim agriculture’s global warming footprint?
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.
Farming makes a huge contribution to global greenhouse emissions, mainly through methane from livestock.

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.
The face of climate evil, or just a juicy steak?
Going vegetarian might help reduce your personal footprint - but it won't save the climate. Richard Eckard explains.
