In Sweden and in other parts of Europe there are concerns that seals and birds compete with humans for fish resources. For the Baltic Sea, an international study now shows that this competition is a reality.
Global carbon emissions are on the rise again in 2017 after three years of little-to-no growth, according to researchers at the University of East Anglia and the Global Carbon Project.
It was previously hoped that emissions might soon reach their peak after three stable years, so the new projection for 2017 is an unwelcome message for policy makers and delegates at the UN Climate Change Conference (COP 23) in Bonn this week.
By the end of 2017, global emissions of carbon dioxide from fossil fuels and industry are projected to rise by about 2% compared with the preceding year, with an uncertainty range between 0.8% and 3%. The news follows three years of emissions staying relatively flat.
That's the conclusion of the 2017 Global Carbon Budget, published 13 November by the Global Carbon Project (GCP) in the journals Nature Climate Change, Environmental Research Letters and Earth System Science Data Discussions.
Policymakers at this week's international climate negotiations in Germany meet amid sobering news that gives their work new urgency. After three years of flat growth, global fossil fuel emissions are rising again, according to a series of reports from the Global Carbon Project, a group chaired by Stanford scientist Rob Jackson.
Ecological studies have demonstrated positive relationships between plant diversity and ecosystem functioning. Forests with higher functional diversity are generally more productive and stable over long timescales than less diverse forests. Diverse plant communities show increased resource use efficiency and utilization, enhanced ecosystem productivity and stability and can better cope with changing environmental conditions - an insurance effect of biodiversity. They are also less vulnerable to diseases, insect attacks, fire and storms.
HANOVER, N.H. - Nov. 13, 2017 - A set of fundamental tactics ranging from the theoretical to the practical can be used to combat the challenges brought on by pests in rapidly changing forests, according to a research paper from Dartmouth College and the University of Santiago de Compostela.
With forests under pressure worldwide due to human activities in what is now often referred to as the Anthropocene era, the researchers analyzed why forests around the world are being impacted by new pests and what can be done about it.
WASHINGTON, DC -- Military service exposes soldiers to a unique set of physical challenges, including toxic chemicals and traumatic brain injury, which can have profound effects on their health and well-being. New research examines the effects of military-related brain disorders and possible paths toward treatment, as well as a potential way to harness our brain's learning capabilities to better train pilots.
New York, NY (November 10, 2017) - Researchers at Columbia University Medical Center (CUMC) and the New York State Psychiatric Institute (NYSPI) may have discovered a way to use a patient's sense of smell to treat Alzheimer's disease before it ever develops. Having an impaired sense of smell is recognized as one of the early signs of cognitive decline, before the clinical onset of Alzheimer's disease.
Researchers from the Physics Department of Moscow State University and their colleagues have discovered a mechanism that allows gas sensors, based on nanocrystalline metal oxides, to work at room temperature. This invention will raise the efficiency of environmental monitoring at nuclear power plants, on submarines and spacecrafts. The discovery was reported in Scientific Reports.
Until recently, it was assumed that the ink used for writing was primarily carbon-based at least until the fourth and fifth centuries AD. But in a new University of Copenhagen study, analyses of 2,000-year-old papyri fragments with X-ray microscopy show that black ink used by Egyptian scribes also contained copper - an element previously not identified in ancient ink.
