Warming seas could shift fish habitats out of the reach of some fishers

Climate change is doing more than causing  sea levels to rise or sea ice to dwindle — it’s pressuring  fish to move far away from their typical habitats. Warming waters have already prompted some fish to migrate south or north. As the climate continues to change, marine species’ shifts could be challenging for fisheries as the fish potentially move into new areas altogether — some hundreds of miles away. Fish are already seeking more favorable habitats in a changing world, and a team of six scientists at institutions in the U.S. and Switzerland decided to predict how they might move in the future. In research published this week in PLOS One , the team modeled the habitat of 686 species. Ecologist and co-author Malin Pinksy of Rutgers University told NPR they have high certainty for how far around 450 of those species will shift in the future. Related: Bottlenose dolphins spotted in Canadian Pacific waters for the first time “We found a major effect of carbon emissions scenario on the magnitude of projected shifts in species habitat during the 21st century,” lead author James Morley of the University of North Carolina at Chapel Hill said in a statement . “Under a high carbon emissions future we anticipate that many economically important species will expand into new regions and decline in areas of historic abundance.” Some species might just shift a few miles. But others might move so far that they become out of reach for some fishers. For example, the Alaskan snow crab could move north as far as 900 miles. A shift of just a couple hundred miles could place lobster or other fish out of the range for fishers with small boats — and limited time and fuel. The scientists aren’t sure when the shifts might happen; it depends on how much the waters warm. But the movement could pose challenges for resource management — co-author Richard Seagraves, formerly with the Mid-Atlantic Fishery Management Council , told NPR that states get a catch limit, or quota, for fish. The catch limit is based on where the fish were decades ago. Seagraves said, “Some of the Southern states are having trouble catching their quota, and states to the north have more availability of fish.” + PLOS One Via NPR and EurekAlert!

On the go? Not a problem. This movable, prefab house from Swiss studio Rahbaran Hürzeler Architekten can be built and installed almost anywhere. The architects developed the project as an experiment in designing a space that can be assembled and transported easily and quickly. Every aspect of the project is designed around mobility, including the structure and floor plans. The house can stand alone or can connect to another building. Four timber cores are the only load-bearing structures that support the concrete roof. Related: zeroHouse offers luxurious living in a fully self-sustaining modular home The structure has four main areas organized around a circular central space, which establishes a flexibility that allows multiple occupants to adapt the design to their own needs and preferences. This also allows users to adjust the organization of the house to a specific site. The floor, made from concrete, can be hauled by truck. Four prefabricated timber cores stand on the floor and create five functional spaces — a kitchen, living room and two bedrooms. The first prototype of the movable home is slated for construction in Basel , Switzerland. It will feature a system of sensors that that allow the occupants to monitor the home’s performance over the course of one year. The architects plan to use this data to further develop and enhance the design. + Rahbaran Hürzeler Architekten Via Archinect

Comments Off on Pakistan just broke the world record for the hottest April day ever

Pakistan hit 122.3 degrees Fahrenheit (50.2 C) this week, marking the highest temperature recorded for the month of April – ever. The city of Nawabshah in Sindh province reported the stunning temperature on Monday, and it was confirmed by the Pakistan Meteorological Department . While Pakistan is getting the worst of it, a huge portion of the planet, from South Asia to Europe and parts of the US, is being hit by a heat wave that threatens to become the new normal. ???Exceptionnel 50.2°C à Nawabshah au #Pakistan ce lundi 30/04/2018, #RECORD national de chaleur pour un mois d'avril ! ???(précédent : 50°C à Larkana le 19/04/2017)*** aussi un nouveau record mensuel pour tout le continent asiatique ! *** pic.twitter.com/GTCOJuDT9Q — Etienne Kapikian (@EKMeteo) April 30, 2018 As you’d expect, the heat was incredibly hard on those living in the area, causing people to pass out, heatstroke reports to increase, and business to shutter. Nawabshah experienced another record just last month, when temperatures climbed to 113.9 F (45.5 C). Areas in India and Eastern Russia have been setting their own records this month as a heat wave moves across the area before monsoon season sets in. Unfortunately, it seems likely that these numbers will become more common. A study completed last year showed that temperatures in India had risen 0.5 C over the past 50 years, with no change in sight. Related: Ocean heatwaves have risen by more than 50% since 1925 In 2011, Santa Rosa, Mexico was said to have hit 123.8 F (51 C), but that number was never confirmed. Pakistan’s measurement is considered to be reliably accurate. However, in order for the figure to qualify as a world record, the World Meteorological Organization will need to verify the number. Just in case you were wondering, Pakistan’s previous April heat record was set last year when temperatures climbed to 122 F (50 C). Via Earther and Al Jazeera Image via Deposit Photos

After 250 earthquakes in 24 hours, Hawaii’s Kilauea volcano might erupt

Comments Off on After 250 earthquakes in 24 hours, Hawaii’s Kilauea volcano might erupt

Out of the five volcanoes on Hawaii’s Big Island, Kilauea is the most active — and it’s threatening to erupt. After a collapse event at the Pu’u ‘?’? vent, in the volcano’s East Rift Zone, around 250 earthquakes happened. Authorities are warning people to remain on alert, because scientists observed magma flowing under a main road close to houses. Will Kilauea erupt? Seismic activity could result in a lava breakout, but Hawaiian Volcano Observatory scientists can’t say exactly what time or where it might happen. The crater collapse and earthquakes are “associated with the continued intrusion of magma into the East Rift Zone to locations east of Highway 130. An outbreak of lava from the lower East Rift Zone remains a possible outcome of the continued unrest,” according to the observatory. The Independent said there are homes in that part of the island, and Highway 130 leads to an access point enabling visitors to hike or cycle to a lava viewing area. Related: Mesmerizing volcano “skylights” give a glimpse under the Earth’s surface Local residents have noticed cracks in roads near the Leilani Estates subdivision, but so far neither heat nor steam have been observed escaping from the cracks, which are small. The Hawaii County Civil Defense Agency said areas that could be impacted are Leilani Estates, Nanawale Estates or Kapoho. The Hawaiian Volcano Observatory offered resources for those who want to stay updated about Kilauea ; sign up for notification emails from the Volcano Notification Service at this USGS website or sign up for the Civil Defense Emergency Notification System at the County of Hawaii website . The volcano’s activity hasn’t always been explosive in the past, but a 1924 eruption spewed ash and rocks into the air and killed one man. The summit crater gushed rock and lava across 75 acres in 2008, and a view point was damaged. + Hawaiian Volcano Observatory (1, 2) + County of Hawaii Via The Independent and CNN Images via Depositphotos and U.S. Geological Survey

Comments Off on This alpine hotel is built with modular rooms stacked together

This minimalist and modular hotel in the mountain resort of Lenzerheide, Switzerland offers a streamlined and modern take on the traditional mountain chalet. Carlos Martinez Architekten designed Hotel Revier with prefabricated room modules, each with a glazed end wall and lined in natural, unfinished plywood. The long and narrow larch-clad building comprises three rectangular segments angled to follow the shoreline of the Heidsee and positioned to face panoramic mountain views. An exercise in minimalism, the sports-oriented Hotel Revier is “reduced to the bare essentials,” wrote Carlos Martinez Architekten. “The hotel unites the atmosphere of a mountain chalet with the liberating feeling of a campervan and the functionality of a ship’s cabin. All rooms face West toward the water and bring to mind the image of a VW bus: one park at the lake opens the tailgate and feels a sense of freedom.” Related: Hotel Tverskaya Transforms a Disused Building in Moscow with Sleepbox Modules The hotel’s communal core, made up of the lobby, bar, and restaurant, occupies the ground floor, while the four floors with a total of 96 rooms are stacked above. The 160-square-foot standard rooms, prefabricated and fully equipped offsite, were assembled into a metal framework. Each standard room includes a wall-to-wall bed that can be folded up into a sofa, TV, floor-to-ceiling window , hooks, narrow ventilation wings, a deep windowsill, and a heating unit for drying gloves and clothing. Hotel Revier also includes four barrier-free and 29 triple-bed rooms, also prefabricated. By stacking the modules side by side, the architects create a “double-wall” effect with the advantage of improved acoustic insulation. + Carlos Martinez Architekten Via ArchDaily Images © Marc Lins, Hannes Thalmann, and Revier Mountain Lodge

How volcanic eruptions in Iceland and Alaska affected ancient Egyptians

Comments Off on How volcanic eruptions in Iceland and Alaska affected ancient Egyptians

Volcano eruptions could have helped precipitate unrest in ancient Egypt , according to a new study. An international team of researchers led by Joseph Manning of Yale University discovered volcanic eruptions in northern latitudes can impact the flow of the Nile River . Ancient peoples depended on Nile River flooding to irrigate crops, and if that flood didn’t happen, there could have been political or economic consequences. The researchers connected historical analysis with paleoclimatology – what Yale described as reconstruction of global climates in the past – to make the startling find. Volcanoes in Russia, Greenland, Iceland, or Alaska could have disrupted the daily lives of people in ancient Egypt. While volcanic eruptions weren’t the sole cause of unrest, the researchers think they did play a role. In years with volcanic eruptions, the Nile didn’t flood as much, which Manning said led to social stress. He told The Washington Post, “It’s a bizarre concept that Alaskan volcanoes were screwing up the Nile, but in fact that’s what happened.” Related: The world’s mightiest river is dying Manning and colleagues took an interdisciplinary approach, scrutinizing ancient papyri and inscriptions for descriptions of Nile flooding, and combining that historical information with climate modeling of big 20th century volcanic eruptions and yearly Nile summer flood height measurements between 622 and 1902. Manning told The Washington Post, “It’s an indirect response, but because of atmospheric circulation and energy budgets, we find that large volcanic eruptions cause droughts .” He described the Nile and Egypt as sensitive instruments for climate change , and said the research was important in today’s debate on climate change. The study offers new insight into how climatic shocks impacted societies in history. Manning said in a statement, “There hasn’t been a large eruption affecting the global climate system since Mount Pinatubo in the Philippines in 1991…Sooner or later we will experience a large volcanic eruption, and perhaps a cluster of them, that will act to exacerbate drought in sensitive parts of the world.” The journal Nature Communications published the study online this month. Five other researchers, from institutions in Ireland, California, and Switzerland, contributed to the work.

Comments Off on New concrete roof includes thin-film PV cells to generate power

Digital design and fabrication techniques allowed researchers in Switzerland to create a curvy, super thin concrete roof that will one day help a residential unit produce more power than it consumes. Using the innovative methods, the researchers assembled the roof with much less materials than would otherwise be needed. The concrete roof is also equipped with thin-film photovoltaic cells to generate energy. Researchers at the Swiss Federal Institute of Technology Zurich (ETH Zurich) recently unveiled the prototype for a sinuous, self-supporting concrete roof. The roof is comprised of multiple layers, including concrete , heating and cooling coils, insulation, and more concrete fitted with thin film solar cells. The prototype was around 25-feet-tall, with a surface area of around 1,722 feet squared. The average thickness of the concrete was around two inches; the support surfaces had a thickness of 4.7 inches and the edges of the roof were just around one inch thick. Related: The company that offered integrated solar roofs before Elon Musk A cable net supporting a polymer textile provided the formwork for the concrete roof. The researchers used a precise concrete mix, fluid enough to be sprayed but firm enough to not flow off. Professor of Architecture and Structures Philippe Block said in a statement, “We’ve shown that it’s possible to build an exciting thin concrete shell structure using a lightweight, flexible formwork, thus demonstrating that complex concrete structures can be formed without wasting large amounts of material for their construction.” The prototype has already been dismantled to make room for other experiments, but in 2018, the roof will be erected atop materials science and technology research institute Empa ‘s HiLo Penthouse. Guest faculty will live and work in the penthouse, which is expected to produce more energy that it uses thanks to the concrete roof’s solar cells and what ETH Zurich described as an adaptive solar facade .

Comments Off on Transformable solar building changes shape to teach people how to live sustainably

How do you persuade people to adopt sustainable lifestyles? A team of Swiss architecture students believes in the power of demonstration—and they’ve designed and built the eco-friendly NeighborHub to prove their point. Conceived as a collaborative community space, the NeighborHub is a transformable, shared space that demonstrates innovative solutions, from renewable energy and water management to biodiversity and sustainable mobility. The NeighborHub is a community space that provides innovation solutions to the challenges of climate change and resource depletion. The building explores seven themes—renewable energy, water management, waste management, mobility, food, material choices, and biodiversity—within a transformable shell built of laminated veneer lumber. “The house is divided into two main spaces,” said the Swiss Team. “The center of the NeighborHub, the core, is a thermally controlled space. It is surrounded by the extended skin which is controlled by passive strategies.” The modular, prefabricated building envelope can adapt to different needs, from a private bedroom to a bicycle repair shop, and even expand its footprint to the outdoors thanks to movable walls and transforming furniture. The NeighborHub’s movable facade is clad in active solar panels and solar thermal panels on the east, south, and west sides. An edible garden grows atop the rainwater-harvesting roof. Two vertical greenhouses are installed to show off space-saving year-round farming techniques such as aquaponics . A zero-water “dry” toilet recycles waste and produces compost that can be used as fertilizer. The rainwater collected from the roof is treated with an on-site phytopurication system and reused for non-potable uses, such as laundry and irrigation. Related: Hurricane-resistant SURE HOUSE wins the 2015 Solar Decathlon The NeighborHub was designed and constructed by the Swiss Team, comprising students from the Ecole Polytechnique Fédérale de Lausanne (EPFL), the School of Engineering and Architecture of Fribourg (HEIA-FR), the Geneva School of Art and Design (HEAD) and the University of Fribourg (UNIFR). The Swiss Team’s solar prototype was developed for the U.S. Department of Energy Solar Decathlon , an academic competition that challenges student teams to design and build full-size solar-powered homes; this year’s contest is held near Denver, Colorado. Following the competition, the NeighborHub will be brought back to the blueFactory in Fribourg, Switzerland for further research and development. + Solar Decathlon Images © Mike Chino

Comments Off on Budapests tallest tower to follow the highest standards of sustainability

Foster + Partners designed a tower for Budapest that will not only be the city’s tallest—it’ll also be a beacon for sustainability. Designed as the new headquarters for the oil and gas company MOL Group , the mixed-use building named MOL Campus is wrapped in glazing to maximize natural daylight, views, and connection with the outdoors and urban fabric. MOL Campus will be powered by low and zero-carbon energy sources, such as photovoltaics, and saves on energy costs with cutting-edge technology that controls light levels and temperatures. Located in southern Budapest , MOL Campus is set to be the tallest building in the city and will comprise a 28-story tower with an integrated podium. In addition to offices, the campus will include a restaurant, gym, conference center, public sky garden, and other facilities. Glass clads the unified, curved volume to provide daylight and views. Greenery, including mature trees, travels through the heart of the building from the central atrium on the ground floor to the public garden at the top of the tower. The architects see the green spaces as a “social catalyst” that encourages collaboration, relaxation, and inspiration in the workplace. Related: New Budapest museum will feature a sweeping green roof resembling a skateboard ramp “As we see the nature of the workplace changing to a more collaborative vision, we have combined two buildings – a tower and a podium – into a singular form, bound by nature,” said Nigel Dancey, Head of Studio, Foster + Partners. “As the tower and the podium start to become one element, there is a sense of connectivity throughout the office spaces, with garden spaces linking each of the floors together.” The building’s location in a dense urban environment allows employees to walk or cycle to work. In addition to use of photovoltaics and energy-saving technologies, MOL Campus will also feature rainwater harvesting and storage facilities. + Foster + Partners Images via Foster + Partners

First newly-developed chocolate in 80 years is made from Ruby cocoa beans

Comments Off on First newly-developed chocolate in 80 years is made from Ruby cocoa beans

Chocolate aficionados rejoice! There’s a new version of your favorite velvety treat, and it’s ruby red in color. Made from the Ruby cocoa bean, the newly-invented variety of chocolate is the first to be developed in 80 years — since white chocolate was introduced to the world. And though we haven’t tried it ourselves, apparently it has a fruity and slightly sour flavor. The new chocolate was recently unveiled in Shanghai, China by Swiss chocolate producer Barry Callebaut . MNN reports the company spent 13 years developing the treat and describes it as a “tension between berry-fruitiness and luscious smoothness.” It’s “an intense sensorial delight,” says the company. Part of the chocolate’s appeal is its unique color, a result of the Ruby cocoa bean’s pigment. The product is all natural and is made using an “innovative process” that unlocks the bean’s unique flavor and color. Barry Callebaut says no berries, berry flavor or any color is added to the chocolate. Related: HOW TO: Make delicious, raw chocolate pudding from avocados! This is the #rubychocolate that everyone is on about. Taste is like white choc w/ berry fruits – but all from bean… pic.twitter.com/NqGs90Lmda — Andrew Baker (@ccAndrewBaker) September 5, 2017 Unfortunately, it will be at least six months until you can try the ruby chocolate for yourself since Callebaut only makes the chocolate, and not the consumer products that would go with it. Raphael Warmth wrote on the company’s Facebook page : “So far you cannot buy the ruby chocolate. This very much depends on our customers when ruby chocolate will be available … as we are a B2B company and selling ruby chocolate to food manufacturers. Usually, it takes from 6 up to 18 months until an innovation from our side hits the retail shelves.” Judging by the gleeful reactions of people taste-testing the ruby chocolate in the video below, it will be worth the wait. + Barry Callebaut Via MNN Images via  Barry Callebaut
