The stomachs of cattle, fermentation in rice fields, fracking for natural gas, coal mines, festering bogs, burning forests — they all produce methane, the second most important greenhouse gas, after carbon dioxide. But how much? And how can we best cut these emissions? And is fracking frying the planet, or are bovine emissions more to…

Danish scientists are developing a grass that will cut down how often cows burp and pass gas — reducing the amount of methane, a potent greenhouse gas, they release into the atmosphere.

Starting in 2019, all new or refurbished homes and apartment buildings in Europe will be required to have electric vehicle recharging stations built on the premises, according to a draft directive from the European Union.

The United Kingdom will begin harnessing energy from kites flying 450 meters above ground as early as next year. Developed by UK-based Kite Power Solutions, the system is composed of two 40-meter wide kites that rise and fall in tandem, spooling a tether line to turn a turbine.

California is testing whether its heavy traffic can produce not just emissions and air pollution, but electricity. The state’s Energy Commission says it will spend $2 million to examine the potential of using piezoelectric crystals embedded under asphalt as a way to send the energy created by moving cars to the grid.

Arctic sea ice extent shrank to 1.6 million square miles earlier this month — tying 2016 with 2007 as the second lowest sea ice minimum since satellite records began. The lowest year remains 2012. The new measurements follow a decades-long trend of declining sea ice extent in the Arctic as global temperatures rise. 

A group of southern elephant seals is helping scientists monitorhow climate change is impacting Antarctica by tracking water temperature, depth, and salinity as they swim and dive around the frozen continent. 

A new graphic created by NASA and the Japan Aerospace Exploration Agency illustrates the severity of a recent rainstorm that caused widespread flooding in Louisiana this week, killing 11 people and forcing tens of thousands of residents from their homes. 

Chinese consumers bought 34,000 new electric cars in July, a 188 percent jump over the same period last year, according to CleanTechnica, an energy and technology news organization. The monthly total puts China on track to sell 400,000 electrical vehicles in 2016, accounting for 1.5 percent of the total auto sales market — larger than annual…

Ocean noise caused by shipping can cause humpback whales to dive more slowly and forage less frequently, according to new research in the journal Biology Letters. A team of U.S. and U.K. researchers tagged 10 humpbacks in Stellwagen Bank National Marine Sanctuary, off the coast of Massachusetts, with devices that simultaneously tracked the whales’ movements and underwater…
