Forest fires have crept higher up mountains over the past few decades, scorching areas previously too wet to burn, according to researchers from McGill University. As wildfires advance uphill, a staggering 11% of all Western US forests are now at risk.
Geothermal energy systems have the potential to power the world and become the leading technology for reducing greenhouse gas emissions if we can drill down far enough into the Earth to access the conditions necessary for economic viability and release the heat beneath our feet. Quaise Inc. is developing a potentially disruptive drilling technology to make that happen. Matt Houde of Quaise presented the approach at the World Geothermal Congress on June 15.
The depths of the Black Sea store comparatively large amounts of organic carbon. A research team led by scientists from the University of Oldenburg, Germany, has now presented a new hypothesis as to why organic compounds accumulate in this semi-enclosed sea and other oxygen-depleted waters. Reactions with hydrogen sulfide play an important role in stabilizing carbon compounds, the researchers posit in the scientific journal Science Advances. This negative feedback in the climate system could counteract global warming over geological periods.
A new article, published as a Perspective in the journal Conservation Science and Practice, introduces a rapid assessment framework that can be used as a guide to make conservation and nature-based solutions more robust to future climate.
Woodlands along streams and rivers are an important part of California's diverse ecology. They are biodiversity hotspots, providing various ecosystem services including carbon sequestration and critical habitat for threatened and endangered species. But our land and water use have significantly impacted these ecosystems, sometimes in unexpected ways.
A long-term passive rewilding study has shown that natural woodland regeneration could make a significant contribution to meeting the UK's ambitious tree planting targets - potentially at no cost and within relatively short timescales. The research, led by the UK Centre for Ecology & Hydrology (UKCEH), found natural growth due to seed dispersal by birds, mammals and wind can produce biodiverse and resilient woodland.
The German National Academy of Sciences Leopoldina and the German Council for Sustainable Development (RNE) have published a joint position paper presenting paths to climate neutrality by 2050. In it, the Leopoldina and the RNE highlight options for action to effect the changes needed within society, at political level and in the business world, in view especially of the urgency and the historic dimensions of the transformation we face.
Current approaches for planning relocation for potentially millions of people affected by climate change are 'woefully inadequate' and risk worsening societal inequities, experts wrote in a policy perspective on June 17 in Science. Policymakers and scientists need to rethink how they work together to develop, communicate and carry out relocation plans so that relocating communities can thrive, though it relies on a transformation in how science is used, tools are deployed, and stakeholders are engaged.
As demand for electricity rises and climate change brings more frequent and extreme storms, residents in rural and suburban communities must have access to the minimal electricity they need to survive a large, long-duration (LLD) power outage.
Weddell seals, the southernmost born mammal, are known as champion divers. But they don't begin life that way. Cal Poly researchers examined the development of diving behavior in Weddell seal pups and found that they time their dives with their mother but likely do not learn to forage at that time. Instead, they focus their early efforts on learning to swim and navigate under the sea ice.
