Average carbon dioxide concentrations, Oct. 1 -

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.
Rice paddies are one of the major sources of methane in agriculture.
Methane concentrations in the atmosphere are growing at a faster rate than any time in the past 20 years.
The EPA has issued rules to regulate methane emission from new oil and gas wells in the face of industry and political pushback.

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.
We need a global target for reducing emissions in agriculture to meet the Paris Agreement. Farmers have an opportunity to help meet the 2 degree C target in the Paris Agreement, but known practices will not be enough.
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.
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.
The Michigan State University has developed a technology which separates the elements in cow manure to make water and fertiliser…
Methane hydrates - fire ice from deep under the sea.
Last year Japanese scientists announced they had for the first time extracted gas from offshore deposits of methane hydrate, an ice-like substance made of natural gas (methane) trapped inside water crystals…
