Threats to habitat connectivity as sea waters inundate coastal areas

By the year 2100, sea levels might rise as much as 2.5 meters above their current levels, which would seriously threaten coastal cities and other low-lying areas. In turn, this would force animals to migrate farther inland in search of higher ground. But accelerated urbanization, such as the rapidly expanding Piedmont area that stretches from Atlanta to eastern North Carolina, could cut off their escape routes and create climate-induced extinctions.

Researchers find better way to 'herd' electrons in solar fuel devices

Researchers at the University of British Columbia and the University of North Carolina at Chapel Hill have discovered a new way to optimize electron transfer in semi-conductors used in solar fuel solutions.

The finding, published today in Nature Chemistry, could have a big impact on devices that convert sunlight into electricity and fuel.

Improving poor soil with burned up biomass

Researchers at the RIKEN Center for Sustainable Resource Science in Japan have shown that torrefied biomass can improve the quality of poor soil found in arid regions. Published in Scientific Reports, the study showed that adding torrefied biomass to poor soil from Botswana increased water retention in the soil as well as —the amount of plant growth.

First Mammal Goes Extinct From Manmade Climate Change

We’ve reached a sad milestone: Climate change has claimed its first mammal species. Scientists have been warning us that a large percentage of species will face extinction thanks to manmade global warming, and the future is unfortunately here.

According to The Guardian, climate change’s first mammal victim was an adorable rodent known as the Bramble Cay melomys. Sometimes called a mosaic-tailed rat, the melomys was named after Bramble Cay, an Australian island close to Papua New Guinea, that was the only known home for the species.

700-year-old West African soil technique could help mitigate climate change

A farming technique practised for centuries by villagers in West Africa, which converts nutrient-poor rainforest soil into fertile farmland, could be the answer to mitigating climate change and revolutionising farming across Africa.

What Would a Global Warming Increase of 1.5 Degrees Be Like?

How ambitious is the world? The Paris climate conference last December astounded many by pledging not just to keep warming “well below two degrees Celsius,” but also to "pursue efforts" to limit warming to 1.5 degrees C. That raised a hugely important question: What's the difference between a two-degree world and a 1.5-degree world?

Judge rules: no right to know hazardous pesticide ingredients

A federal judge has ruled that the US Environmental Protection Agency is under no obligation to force pesticide makers to disclose supposedly 'inert' ingredients in their products - even where those ingredients are seriously hazardous to health or environment.

Fossil record shows seas around Britain were once tropical

Some 210 million years ago, Britain consisted of many islands, surrounded by warm seas. Europe at the time lay farther south, at latitudes equivalent to North Africa today. Much of Europe was hot desert, and at this point was flooded by a great sea – the Rhaetian Transgression.

Published in Proceedings of the Geologists' Association, the Bristol team's work is the most extensive study yet, based on more than 26,000 identified fossils, of the Rhaetian shallow sea sharks, bony fishes, marine reptiles, and other creatures. Unusually, five members of the team were undergraduates when they did the work, and this was part of a series of summer internships.

The team was led by Ellen Mears, now a postgraduate at the University of Edinburgh, and Valentina Rossi, now a postgraduate at the University of Cork.

Ellen Mears said: "I studied the shark and fish teeth, and found remains of at least seven species of sharks and four of bony fishes. The sharks were all predators, but some were quite small. The bony fishes were unusual because many of them were shell crushers."

New generation of high-efficiency solar thermal absorbers developed

Researchers from the Universities of Bristol and Exeter are one step closer to developing a new generation of low-cost, high-efficiency solar cells. The structure is one of the world's first examples of a tri-layer metasurface absorber using a carbon interlayer.

A Plan to Mute Ocean Noise for Marine Life

Imagine trying to relax in your home while being bombarded with the explosive sounds of shotgun blasts as well as freight trains rumbling by. For many whales, dolphins and other marine life that depend on their hearing to survive, there is no way to escape the loud, human-made noises in their ocean home. The main culprits are vessels like cargo ships, along with sonar guns used by the U.S. Navy and air guns used in seismic oil and gas exploration. Their blasts are so loud that they are known to change the behavior of blue whales. But now, in what Michael Jasny, director of the Natural Resources Defense Council’s Marine Mammal Protection Project, Land & Wildlife Program, referred to as “a sea change in the way we manage ocean noise off our shores,” NOAA has announced it plans to take action to reduce the noise in entire marine ecosystems.
