Farming makes a huge contribution to global greenhouse emissions, mainly through methane from livestock. Billy Hathorn/Wikimedia Commons

Meat the future: new book sets out the effects of the world’s diet

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.
Methane hydrates - fire ice from deep under the sea. Wusel007

Japan’s quest to tap the natural gas beneath the ocean floor

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…
Is this a sunset, or sunrise, for fracking? danielfoster437

Shale gas: make polluters pay for the social cost of fracking

While the prime minister has shown unequivocal support for exploiting Britain’s shale gas reserves, stating the country should “go all out for shale gas”, more cautious voices point to possible effects…

Methane emissions found to be underestimated

The USA’s methane emissions, a type of greenhouse gas, have been found to be severely underestimated according to new research…

Melting Arctic’s methane timebomb could cost trillions

Arctic sea ice is retreating, with projections suggesting that the summer months will be substantially ice-free within the next few years. Nations are waking up to the possibilities for shipping and resource…

Mapping methane across America

Researchers in the US have done the first ever whole-country study of methane emissions. In some cases they found higher…
Take care! The precautionary principle can only go so far without data to rely on. Jeremy Buckingham

Environmental assessment of coal seam gas lacks scientific back-up

Yesterday, the Federal government issued new recommendations for methods to estimate emissions from conventional gas and from coal seam gas production. So what did we learn? The proposals seek to refine…
Dairy farmers will be able to claim carbon credits if they feed their cows right. Eli Duke

Reducing methane from dairy cows: it’s all in the oil

The Carbon Farming Initiative is about to provide incentives for dairy farmers to reduce emissions from their milking cows. Emissions will be reduced by changing the cows' diet. The proposed new methodology…
By studying ice cores, researchers can measure the methane emissions from thousands of years earlier. Arabani/Flickr

Humans did affect the atmosphere - even before industrialisation

The past is the key to the future. When snow falls on polar ice sheets, in Greenland and Antarctica for example, air is trapped between the snowflakes. Year after year, the snow compacts under its own…
Methane locked under the Arctic ice could take climate change to a whole new level. Antonio Delgado Huertas

Methane hydrates: a volatile time bomb in the Arctic

The risk with climate change is not with the direct effect of humans on the greenhouse capacity of Earth’s atmosphere. The major risk is that the relatively modest human perturbation will unleash much…
