Climate change is the big wild card when it comes to the survival of many Arctic species. A new study shows that climate change will be both good and bad for Svalbard barnacle goose populations -- although the balance may tip depending upon the severity of future temperature increases, and how other species react.
A research team investigated the impact of extreme fires on previously intact carbon stores by studying the soil and vegetation of the boreal forest and how they changed after a record-setting fire season in the Northwest Territories in 2014. They collected 200 soil samples and used radiocarbon dating to estimate the carbon age. They found combustion of legacy carbon in nearly half of the samples taken from young forests (less than 60 years old).
California leads the nation in the adoption of rooftop solar systems, but information on which communities do, and do not, benefit from these installations has been limited. The adoption of distributed solar -- rooftop installations as opposed to industrial-scale operations like solar farms -- is closely correlated with socioeconomic status and health, environmental and demographic indicators. The study, published online August 20, 2019 in Energy Policy, is the first peer-reviewed analysis of distributed solar adoption in disadvantaged communities.
Those who wish to leave their own country of origin in the European Union (EU) can currently do so without complications: with the right to freedom of movement, the EU offers its citizens unique conditions for migration. A study by the Universities of Göttingen, Bremen and Cologne has now shown that Germany and United Kingdom are the most popular destination countries for migration within Europe. Their research was published in the Journal of Ethnic and Migration Studies.
Researchers at the George Washington University have developed a mapping model, the first of its kind, to track how hate spreads online.
Speeding is the riskiest kind of aggressive driving, according to a unique analysis of data from on-board devices in vehicles.
A two-year randomised controlled trial in the British Ecological Society journal Functional Ecology will be the largest of its kind to date to assess whether hiding author details during peer review reduces bias against underrepresented groups in the science publishing process.
The growing number of children arriving at Texas schools unvaccinated makes the state increasingly vulnerable to measles outbreaks in cities large and small, according to a computer simulation created by the University of Pittsburgh Graduate School of Public Health. The findings indicate that a 5% further decrease in vaccination rates that have been on a downward trend since 2003 would increase the size of a potential measles outbreak by up to 4,000% in some communities.
Injecting carbon dioxide (CO2) deep below the seabed could be an important strategy for mitigating climate change, according to some experts. However, scientists need a reliable way to monitor such sites for leakage of the greenhouse gas. Now, researchers reporting in ACS' journal Environmental Science & Technology have studied natural sources of CO2 release off the coast of Italy, using what they learned to develop models that could be applied to future storage sites.
Almost one-third of people migrating to the US via Mexico experience physical, psychological, and/or sexual violence along the way, according to a study published Aug. 21, 2019 in the open-access journal PLOS ONE by René Leyva-Flores and Cesar Infante from the National Institute of Public Health (Mexico), Juan Pablo Gutierrez from the National Autonomous University of Mexico, and colleagues.
