Crucial peatlands carbon-sink vulnerable to rising sea levels

<!– –> Rising sea-levels linked to global warming could pose a significant threat to the effectiveness of the world’s peatland areas as carbon sinks, a new study has shown. The pioneering new study, carried out by Geographers at the University of Exeter, examin

Ocean acidification affects predator-prey response

Ocean acidification makes it harder for sea snails to escape from their sea star predators, according to a study from the University of California, Davis. The findings, published in the journal Proceedings of The Royal Society B, suggest that by disturbing predator-prey interactions,

Climate Change Is Happening Faster Than African Crops Can Handle It

<!– –> Crop yields in Africa will nosedive ten years from now unless we can develop varieties that can better deal with climate change. Unfortunately, we’re not breeding those hardier varieties fast enough. That’s the sobering conclusion of a study published in the j

Pipelines affect health, fitness of salmon, study finds

<!– –> Pipelines carrying crude oil to ports in British Columbia may spell bad news for salmon, according to a new University of Guelph-led study. Exposure to an oil sands product – diluted bitumen – impairs the swimming ability and changes the heart stru

Neonicotinoid pesticides cause harm to honeybees

<!– –> One possible cause of the alarming bee mortality we are witnessing is the use of the very active systemic insecticides called neonicotinoids. A previously unknown and harmful effect of neonicotinoids has been identified by researchers at the Mainz University M

Picky eaters: Bumble bees prefer plants with nutrient-rich pollen

<!– –> Bumble bees have discriminating palettes when it comes to their pollen meals, according to researchers at Penn State. The researchers found that bumble bees can detect the nutritional quality of pollen, and that this ability helps them selectively forage among

Wind-blown Antarctic sea ice helps drive ocean circulation

Antarctic sea ice is constantly on the move as powerful winds blow it away from the coast and out toward the open ocean. A new study shows how that ice migration may be more important for the global ocean circulation than anyone realized. A team of scientists used a computer model to

Warning from the past: Future global warming could be even warmer

<!– –> Future global warming will not only depend on the amount of emissions from man-made greenhouse gasses, but will also depend on the sensitivity of the climate system and response to feedback mechanisms. By reconstructing past global warming and the carbon cycle

Where do rubber trees get their rubber?

<!– –> Researchers at the RIKEN Center for Sustainable Resource Science (CSRS) in Japan along with collaborators at Universiti Sains Malaysia (USM) have succeeded in decoding the genome sequence for Hevea brasiliensis, the natural rubber tree native to Brazil. Publis

2 ways to limit the number of heat-related deaths from climate change

<!– –> By the 2080s, as many as 3,331 people could die every year from exposure to heat during the summer months in New York City. The high estimate by Columbia University scientists is based on a new model–the first to account for variability in future populat
