MIT scientists modeled the number of “outdoor days” — with comfortable temperatures for outside activities — that U.S. regions will experience as climate warms. States in the Southeast will lose a significant number of outdoor days, while the Northwest should see a slight increase.
More than half of the risk for mental disorders can be attributed to environmental factors such as socioeconomic status, urbanicity, pollution, and climate. Scientists are trying to characterize the impact of these factors on mental health and develop new ways to reduce the burden. This requires collecting and combining large datasets of different types. Researchers from the Earth, Brain, Health Commission published an article in Nature Mental Health, explaining how to combine data from around the world to draw reliable conclusions.
Just published research from multiple ice cores collected across Greenland with data spanning up to 120,000 years provides new understanding of abrupt Dansgaard-Oeschger events, how they unfold and what that might mean for the future.
In the US, state and federal governments regularly fight wildfires that threaten people and property, but Alaska’s Yukon Flats National Wildlife Refuge recently began piloting a novel strategy: putting out fires to prevent climate-warming carbon emissions from being released from trees and soils.
As the first refuge in the US to use fire suppression to protect carbon, the Yukon Flats experiment comes with some unique challenges. Due to limited budgets and firefighting resources, refuge managers face difficult decisions around when and where to prioritize firefighting efforts — all while navigating scientific uncertainties around how different actions will impact carbon storage.
Now, thanks to a $500,000 grant from the Department of Interior’s Joint Fire Science Program, Cary Institute scientists will assist Yukon Flats refuge staff by providing scientific insights vital to decision making. Over the course of the three-year project, Cary scientists will map how carbon is distributed across the refuge’s forests and soils, identify areas at highest risk of burning, and help fill in other data gaps to inform fire suppression strategies.
More than 800,000 km2 of the Arctic were affected by human activity in 2013, according to an analysis of satellite-derived data on artificial light at night. On average, 85% of the light-polluted areas are due to industrial activities rather than urban development. According to the international team led by UZH researchers, the results are crucial for sustainable development and nature conservation in this highly vulnerable region.
