A moss capable of removing arsenic from contaminated water has been discovered by researchers from Stockholm University. And it happens quickly – in just one hour, the arsenic level is so low that the water is no longer harmful for people to drink. The study has been published in the journal Environmental Pollution.

Plants may have exerted greater influence on our terrestrial ecosystems than the megaherbivores that used to roam our landscapes, according to new research.

REDD+ (Reducing emissions from deforestation and forest degradation) is an UN-led programme aiming to increase carbon sequestration in tropical forests. REDD+ is included among technologies for negative emissions, which stand for a large share of the emission reductions in the climate models internationally agreed on to keep global warming below 2°C. But increasing forest cover in developing counties can threaten other values, as shown in this new study. In southern Ethiopia the tree heather heathlands above the treeline are regularly burnt in order to improve livestock pasture, a practice that authorities within the REDD+ system now tries to stop in order to increase carbon storage. A new study from Stockholm University shows that the ancient pasture burning maintains biodiversity and habitats for alpine plant species not found anywhere else

The Greenland Ice Sheet is melting, discharging hundreds of billions of tons of water into the ocean each year. Sea levels are steadily rising.
