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…
Cows' methane emissions can be measured with lasers, but it’s not that easy to measure emissions from an extinct sauropod. Mark Witton

How do you make a dinosaur burp in a bag? Measuring prehistoric methane

Last week my colleagues and I published a paper showing how methane emitted by dinosaurs could have affected the world’s climate. The media response was huge, with 100+ interviews by email and phone, and…
It looks delicious, but is a diet free of red meat better for the planet? stu spivack

Could your diet save the planet?

By now most of us have read articles suggesting we “eat less red meat and save the planet”. Some may also have heard statements by the chairman of the Intergovernmental Panel on Climate Change, Dr Rajendra…
