Tropical lakes may emit more methane

Methane is not the most abundant greenhouse gas in our atmosphere, but it is among the most potent. Roughly a quarter of global methane emissions come from natural sources, and freshwater ecosystems are the largest source ...

Climate impact of hydropower varies widely

Hydropower is broadly considered to be much more environmentally friendly than electricity generated from fossil fuels, and in many cases this is true. However, a new study reveals that the climate impact of hydropower facilities ...

Defusing the methane bomb—we can still make a difference

The Arctic is warming twice as fast as the rest of the planet, causing the carbon-containing permafrost that has been frozen for tens or hundreds of thousands of years to thaw and release methane into the atmosphere, thereby ...

Methanotrophs: Could bacteria help protect our environment?

New insight into methanotrophs, bacteria that can oxidise methane, may help us develop an array of biotechnological applications that exploit methane and protect our environment from this potent greenhouse gas.

Methane emissions traced back to Roman times

Emissions of the greenhouse gas methane into the atmosphere can be traced back thousands of years in the Greenland ice sheet. Using special analytical methods, researchers from the Niels Bohr Institute, among others, have ...

China builds base to tap deep-sea energy: state media

China will build a multi-million-dollar research base on its east coast as it steps up its efforts to search for energy sources and rare earths on the ocean floor, state media said Friday.
