The Arctic is contuing to warm at an unprecented rate - and the changes are likely to be permanent, says the National Oceanic and Atmospheric Administration (NOAA).
GE scientists and researchers at the University of Maryland have designed a prototype 1,500-lumen LED bulb that taps jet engine cooling technology to prevent overheating.
Presumably recognising that most people are motivated more by money than by beauty, a UN report has attempted to put a price on biodiversity.
Driving a car helps hike global temperatures in the long run more than making the same long-distance journey by air, the American Chemical Society says.
GE has introduced an incandescent-shaped light bulb that combines the instant brightness of halogen technology with the energy efficiency of a compact fluorescent (CFL) bulb.
The US may be set for severe and prolonged droughts in the coming decades, a new government study has found.
The worst coral die-off in ten years - possibly ever - has struck across the Southeast Asian and Indian Oceans.

A new discovery at Rutgers University looks likely to lead to the creation of efficient and inexpensive solar cells made of plastic.
It's completely counter-intuitive, but it now seems that increased solar activity actually leads to cooling on Earth.
The Copenhagen Accord is so full of holes that even if countries stick to their targets there could still be a 4.2-degree rise in temperature by 2100, says a new report.
A North Carolina State University-led team has created 'artificial leaves – water-gel-based solar devices which can act like solar cells to generate electricity.

The ozone layer is regenerating, and could be back up to strength by the middle of the century, according to a UN report.
The Edison2 team clearly put more effort into designing its fuel-efficient car than it did coming up with the name, and it's paid off: the Very Light Car No 98 has earned its designers $5 million from the X Foundation.
