Bitcoin and other cryptocurrencies have promised a revolution in capital - but at what cost? The Bitcoin network alone is now burning a horrific 240 kilowatt-hours of electricity per transaction, using as much energy as the entire nation of Serbia, and heralding an environmental disaster.

Some of the excess carbon dioxide in the air is absorbed by “carbon sinks” like forests and oceans, which helps slow down, but not stop, the greenhouse effect. Unfortunately, a new study has found that oceans are gradually becoming less effective carbon sinks, thanks to rising global temperatures.

In the fight to cut greenhouse gas emissions, we tend to think of trees as our allies, but new research suggests they might not be as "green" as we think. Researchers have found that some types of trees emit methane through their trunks, partly countering their role as a greenhouse gas sink.

Taking advantage of the fact that Google's Street View cars are constantly roaming our urban corridors, a novel project has incorporated methane-sensing equipment into the cars so accurate data can be generated to better target pipeline repairs.

A new study suggests that like a bad smell that continues to linger in a room, even when short-lived greenhouse gases disappear from the atmosphere, they'll continue to have effects in the form of rising sea levels for centuries to come.

A team led by the US Department of Energy's Pacific Northwest National Laboratory (PNNL) has come up with a genetically engineered strain of rice that not only produces almost no methane, but also more grains.

A team of researchers has worked to produce a new model to predict the future changes in glaciers in the Everest region of the Himalayas. While the study only represents an initial approximation of ice loss in the region, the model suggests that dramatic changes may be ahead.
