Greenhouse emissions
-
New analysis has revealed that emissions of methane, a particularly potent greenhouse gas, have now hit record highs, with the surge being driven in large part by increases in the burning of fossil fuels and increasing agricultural activity.
-
Making cement is one of the biggest contributors of carbon emissions. Now MIT researchers have developed a new method that can clean up the process.
-
Livestock like sheep and cows are responsible for huge amounts of methane emissions. Now, an international team of researchers has analyzed the gut microbes of different sheep and found clues that may help us curb the problem.
-
A new study has independently measured methane emissions from a number of ammonia fertilizer plants. The startling results suggest methane emissions are 100 times higher than industry estimates, and three times higher than the EPA’s estimate for all industry methane emissions in the United States.

Do meal kits have a larger carbon footprint than regular grocery store shopping? A team of environmental researchers set out to crunch the numbers discovering that despite the extra plastic waste meal kits may produce less environmental emissions than conventional grocery shopping.

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.
