Tundra CO2 release exacerbates climate warming

Thawing permafrost in high-altitude mountain ecosystems may be a stealthy, underexplored contributor to atmospheric carbon dioxide emissions, new University of Colorado Boulder research shows. The new findings, published today in the journal Nature Communications, show that alpine tundra in Colorado’s Front Range emits more CO2 than it captures annually, potentially creating a feedback loop that…

Conservation policy and sustainable fisheries 

There are roughly five times as many recreational fishers as commercial fishers throughout the world. And yet, the needs and peculiarities of these 220 million recreational fishers have largely been ignored in international fisheries and conservation policy. This gives rise to conflicts and loss of social welfare, and is not conducive to the sustainable management…

Floodplain forests under threat

A team from the Institute of Forest Sciences at the University of Freiburg shows that the extraction of ground water for industry and households is increasingly damaging floodplain forests in Europe given the increasing intensity and length of drought periods in the summer. The scientists have published their results in the journal Frontiers in Forests…

Sea level rise in California could exceed worst wildfires and earthquakes

In the most extensive study to date on sea level rise in California, researchers say damages by the end of the century could be far more devastating than the worst earthquakes and wildfires in state history. A team of U.S. Geological Survey scientists concluded that even a modest amount of sea level rise—often dismissed as…

“Glacier-wise, it’s not a great story”

Beyond the continually grim news from the north and south poles is the melting of the “third pole,” known as the Hindu Kush Himalaya region. Spreading over 2,000 miles across eight nations (from Afghanistan to Myanmar), these mountainous lands are home to the third-largest stores of ice on the planet and provide water to hundreds…

Reducing uranium concentration in contaminated water

In a paper to be published in the forthcoming issue in NANO, researchers from China have proposed a way to reduce Uranium concentration in contaminated water. As an essential nuclear fuel, Uranium has been greatly used an inevitably released to the environment. Without proper disposal, exposure to uranium can result in serious harms to the…

Gardens in urban ecosystems

A healthy community requires healthy soil.” This idea spurred a consortium of researchers, farmers, and community garden practitioners to dive into the challenges–and opportunities–of urban agriculture. Their efforts, now in a second year, may highlight how urban soil can be a resource for human and environmental health. “We can benefit from how we manage the…

Potential impacts of future heat waves on humans and wildlife

Climate change is often talked about in terms of averages — like the goal set by the Paris Agreement to limit the Earth’s temperature increase to 2 degrees Celsius. What such numbers fail to convey is that climate change will not only increase the world’s average temperature, it will also intensify extreme heat waves that…

Wild Plan to Dim The Sun Might Work Safely

In a new study, researchers say spraying chemicals into the atmosphere to ‘dim the Sun’ has never been a magical fix-all to cure humanity’s dangerous addiction to burning fossil fuels, but if used carefully – with a goal of only halving global temperature increases – it could safely work after all. “Some of the problems…

Effects of climate change on real estate investments

But you don’t need to be a scientist to understand that economic and physical climate change effects could adversely affect real estate. Risks exist at all geographic scales and places: along seacoasts; within watersheds; on hillsides; and in vulnerable urban, suburban and exurban areas. Individual buildings likewise are at risk, depending on their location and…
