Comments Off on Pacific heat wave threatens coral reefs in Hawaii and other regions

Researchers predict a major marine heat wave in the Pacific Ocean could prove disastrous to the fragile coral reefs along Hawaii’s Papa Bay and similar coastlines. Warmer water conditions often trigger coral bleaching, a condition that leaves coral reefs susceptible to mortality. Coral reefs play a very significant environmental and ecological role. As a habitat, for instance, they support many species in the marine environment. Coral reefs likewise serve as a protective barrier, buffering shorelines against deleterious wave action, especially during typhoon season, to minimize coastal damage and to prevent erosion. Healthy reefs contribute to local economies, particularly through tourism as well as commercial and recreational fishing. Related: ‘The Blob’ returns — marine heatwave settles over Pacific Unfortunately, when water is too warm, coral become stressed. They consequently expel the algae , or zooxanthellae, that live in their tissues. In doing so, coral turn white, a condition known as bleaching. Prolonged loss of the algae eventually leads to the coral’s demise. When coral reefs are compromised, the loss cascades, often causing far-reaching ecosystem repercussions. Back in 2015, a prominent marine heat wave eliminated half of the Papa Bay coastline’s coral reefs that surround Hawaii’s Big Island. This year, marine scientists associated with NOAA similarly predict that another round of very warm water will occur in the region once again. “In 2015, we hit temperatures that we’ve never recorded ever in Hawaii ,” NOAA oceanographer Jamison Gove said. “What is really important — or alarming, probably more appropriately — about this event is that we’ve been tracking above where we were this time in 2015.” Earlier this September, NOAA researchers warned of the Blob’s return. The Blob — the moniker coined by Washington state climatologist Nick Bond during the 2015 heat wave — describes the vast expanse of unusually warm water that occurred in the Pacific Ocean from 2014 to 2016. It adversely impacted coral reefs, causing global bleaching and diminished coastal fisheries’ yields throughout the Pacific. To date, this year’s Blob is reportedly the second-largest marine heat wave ever recorded in the past 40 years, just behind the 2014 – 2016 Blob. As a result, forecasts anticipate an even warmer October, which could critically undermine the coral that are still recovering from the first Blob. “Temperatures have been warm for quite a long time,” Gove continued.  “It’s not just how hot it is — it’s how long those ocean temperatures stay warm.” While scientists are not yet able to pinpoint the exact causes for ocean temperatures warming, it is believed human-influenced climate change is a salient factor. Restoration efforts are in the works. Research suggests coral can be conditioned to withstand future onslaught of warmer water. Both scientists and coral hobbyists are on a mission to breed “super corals” resilient enough to avoid bleaching. It is hoped the introduction of these “super corals” into the environment will fortify reefs to better evolve amidst global warming conditions. Via Associated Press Images via Terri Stewart and NOAA

‘The Blob’ returns: marine heatwave settles over Pacific

Comments Off on ‘The Blob’ returns: marine heatwave settles over Pacific

Rising ocean temperatures are rising in the northeast Pacific, similar to conditions presented in 2015. It is safe to say the marine heatwave known as the “Blob” has returned. This time the Blob’s 2019 return is the second largest to occur in the Pacific in at least 40 years. It encompasses 4 million square miles from Alaska to Canada and as far away as Hawaii, according to the National Oceanic and Atmospheric Administration. “It’s on a trajectory to be as strong as the prior event,” said Andrew Leising, a research scientist at NOAA. “Already, on its own, it is one of the most significant events that we’ve seen.” Related: Deadly heatwaves may make parts of China uninhabitable by the end of the century The Blob got its ominous name from Washington state climatologist and University of Washington scientist Nick Bond when the 2015 heatwave happened. The more recent Blob popped up in an area of high pressure stationed over the region. Such an incident forces warm surface waters to swirl around allowing cool, wholesome water from below to rise and takeover. “We learned with ‘the Blob’ and similar events worldwide that what used to be unexpected is becoming more common,” said Cisco Werner, NOAA fisheries director of Scientific Programs and chief science advisor. Without this churning process, surface heat can build up and if there are no nutrients from the cooler water below, the heatwave agitates the food chain. Overall, this creates less food for marine life and compels animals to go beyond their immediate home in search of food or simply die off. Underwater creatures aren’t the only things to suffer as humans who bank on the ocean’s physical condition are also affected. For instance, commercial fishing businesses in some places have shut down like Fisheries and Oceans, Canada, which has limited fishing rights for First Nations. Scientists also report should the Blob stick around it could be a bigger threat than it was in 2015. “There are definitely concerning implications for the ecosystem ,” added Bond. “It’s all a matter of how long it lasts and how deep it goes.” Via Gizmodo, National Oceanic and Atmospheric Administration Image via NOAA

Comments Off on The World Surf League is pledging to eliminate single-use plastics and become carbon-neutral by the end of 2019

The World Surf League (WSL)  is known for being the authority for all things surfing, famous for showcasing the most talented professional surfers to the rest of the world. Now, they’ve decided to use that powerful platform to set an example for sports organizations everywhere by committing to substantial environmental initiatives. Earlier in June, the WSL announced a series of pledges that will apply to all WSL Championship Tour and Big Wave Tour events. They include becoming carbon neutral globally by the end of 2019, eliminating single-serve plastics by the end of 2019 and leaving each place better than they found it. The WSL runs more than 230 global surfing events each year. Considering the WSL’s millions of passionate fans, and the organization’s plan to hold competitions throughout Australia, Indonesia, Brazil, South Africa, Tahiti, France, Portugal, California and Hawaii in 2019 alone, these public commitments are bound to inspire others to address critical issues about the state of our environment. Related: Kin Travel is offering unique vacation ideas that benefit destinations through conservation and sustainability Along with the announcement came an expansion of the WSL’s already-active ocean conservation efforts by their launch of a global campaign to “ Stop Trashing Waves ” with its non-profit arm, WSL PURE (“Protecting Understanding and Respecting the Environment”). WSL CEO Sophie Goldschmidt spoke of breaking new ground in the world of sports when it comes to the “urgent battle against climate change and ocean pollution,” saying, “We believe it’s our responsibility to be ‘all in’ with our efforts to protect the ocean and beaches amid the devastating climate crisis we all face. We invite everyone who cares about the ocean to join us.” So how does the WSL plan on carrying out these goals? For starters, the organization is offsetting its carbon footprint by investing in REDD+ and VCS (Verified Carbon Standard) certified carbon offset projects. These projects are focused on restoring and protecting natural and renewable energy ecosystems based in each of the WSL’s operating regions. The WSL will also be making an effort to limit non-essential travel and implement policies to reduce carbon emissions within its offices. 11-time WSL Champion and surfing legend, Kelly Slater, spoke of the announcement with enthusiasm. “I think it’s a great stance and an important message to send to people around the world. The ocean is vital to everyone, for food, for oxygen and especially to us surfers. I think everyone should make it their priority to care about this issue and make changes in their lives to help.” + World Surf League Images via World Surf League

Trash collecting device returned to Pacific garbage patch

Comments Off on Trash collecting device returned to Pacific garbage patch

A giant floating, trash collecting boom is en-route to return to the Pacific ocean after necessary repairs. Initially placed between California and Hawaii in 2018, the boom broke apart due to constant wind and wave pressure and had to be brought back to mainland for service. The 2,000 foot device is now ready to return to the high seas and expected to collect five tons of plastic trash every month. The project aims to clean up what is known as the Pacific Garbage Patch , a widespread issue of marine debris in the Pacific Ocean. Despite dramatic images of heaps of garbage floating on top of the sea, the reality is that the majority of plastic in the northern Pacific is already broken down into micro-plastic particles so small they can be difficult to see and hard to photograph but detrimental to marine life. Related: Ocean explorer finds plastic waste during world’s deepest dive The C-shaped boom mimics a natural coastline and uses the currents to collect plastic garbage. It has solar lights, satellite antennas, cameras and sensors in order to ensure the team behind the project– the Ocean Cleanup Project– can find it at all times. The contraption also has a “skirt” that stretched almost 10 feet below the surface to collect plastic particles floating just below the water level. The boom does not negatively impact marine wildlife , as the majority can easily swim below the skirt. The Ocean Cleanup Project plans to use the boom to collect about five tons of garbage every month, which is collected and towed by a collection vessel. “Hopefully nature doesn’t have too many surprises in store for us this time,” tweeted Boyan Slat, founder of the Ocean Cleanup Project. “Either way, we’re set to learn a lot from this campaign.” via The Guardian Image via The Ocean Cleanup

Rafting outfitters focus on sustainability

Comments Off on Rafting outfitters focus on sustainability

Rafting draws a group of nature lovers with higher than average respect for keeping wilderness clean. But even the raft outfitting industry faces environmental issues— both in external threats to river quality and, in a much smaller way, in making sure their participants are educated in Leave No Trace best practices. “Rafters, both commercial and privates, are extremely conscientious and respectful of the river and its environment,” said Steve Lentz, owner of Idaho-based Far & Away Adventures . His company rafts three Wild and Scenic rivers: the Middle Fork of the Salmon, the Jarbidge/Bruneau and Owyhee rivers — two of the newest to win Wild & Scenic designations, which are especially prized for their solitude and remoteness, Lentz said. But Lentz can remember when people weren’t so respectful of rivers. When he explored the Middle Fork as a child in the 1960s, toilet paper and other garbage littered the riverbanks and people thought nothing of washing with soap in the river. Once the Wild and Scenic Rivers Act passed in 1968, he watched people’s environmental IQ increase while litter decreased. Inhabitat talked to five rafting outfitters to see how their staff and customers can have an impact on keeping rivers clean and beautiful. Related: Seven commandments of Leave-No-Trace Camping Sustainable Rafting Practices Guided rafting trips start way before the raft goes in the water . That’s why Hood River, Oregon-based Northwest Rafting Company’s sustainability measures begin with its office and the supplies they buy. NWRC uses software for reservations and online registration, resulting in minimal printed paper. They’re one of a growing number of outfitters who use online waivers and forms to cut printing. Outfitters are well-versed in Leave No Trace principles. “Fortunately, we live in a state that is environmentally conscious,” said Andy Neinas, owner of Echo Canyon River Expeditions, which rafts Colorado’s Arkansas River above and through the famed Royal Gorge. “The rafting industry is scrutinized by Colorado Parks and Wildlife, and our outfitter organizations work closely to meet and exceed the standards set forth. Colorado Tourism Office works with the Leave No Trace organization to promote responsible use of our natural resources.” Leave No Trace is more rigorous than many people realize. Zachary Collier, owner of Northwest Rafting Company, says this even includes burnt wood. “I suggest all groups use a fire blanket to capture coals from fires,” he advised. Guides and guests sweep the campsite for micro-trash , such as bread crumbs and orange peels. Nor are rafters allowed to leave human waste, let alone toilet paper. Portable toilets are sealed and transported between campsites, and later carried out at the end of the journey. Bob Klein, manager of A Wanderlust Adventure , which rafts Colorado’s Cache la Poudre River, emphasizes the responsibility of the guides. “We believe that rafting outfitters should be enforcing Leave No Trace, educate their guests on the dangers and effects of human recreation on the natural environment, and to keep the amount of rafters they take down the river to the Forest Service’s regulations.”  But the responsibility doesn’t entirely fall on the guide— all rafting participants need to make good choices. “High water looks like fun, but fun can turn to tragedy very quickly when people’s skill levels don’t meet the river’s demand,” said Ron Blanchard, owner of Wyoming River Trips , which operates on the Main Shoshone River.  “We try to mentor rafters when conditions are extreme with information as to what to lookout for.  Most times if you talk with them and not to them, they get the point.” The Bigger Picture Lots of issues facing rivers are beyond people’s individual control. For example, Collier mentions the damage caused by mining .  “The 1872 mining law allows for mining on these rivers and their tributaries even if they are protected,” he said. Neinas has also faced the dumping of hard metals from mining operations near the river’s headwaters close to Leadville, Colorado. “As well as fish kills that resulted from attempts to eradicate invasive species ,” he said. Blanchard mentioned agricultural field runoff as the main threat to the Shoshone. Several outfitters urged rafters to be more proactive in protecting their beloved rivers. “I would love for more guides and outfitters to call, write, or visit Congress to share why these rivers are important and why they should be protected,” said Collier. He and some fellow guides recently visited Washington, D.C. to meet with their representatives about environmental conditions. Lentz agreed. “Be involved and get out of the back seat. From forest plans regarding management to breaching dams that harm the river. Support organizations that that prioritize efforts to strengthen the wilderness and its environment.” Each guide has a special relationship with his or her river, and can tell you 100 reasons it needs protection. For example, Lentz expounded on the attractions of the Middle Fork of the Salmon River: “Alpine forests , hot springs, blue ribbon fly fishing for native cutthroat trout, hiking well maintained trails, crystal clear water, 100 rapids, North America’s third deepest canyon, wildlife including elk, deer, bighorn sheep, mountain goat, both golden and bald eagle, cougar, black bear to name a few.” Are rivers worth protecting? You bet. Photos via Echo Canyon River Expeditions, skeeze

A Hawaiian island has been wiped out by Hurricane Walaka

Comments Off on A Hawaiian island has been wiped out by Hurricane Walaka

Hurricane Walaka, a powerful hurricane that hit Hawaii earlier this month, has wiped a Hawaiian island off of the map. East Island, a remote, 11-acre area of gravel and sand that sat on top of a coral reef, has disappeared after coming into contact with the intense storm. According to The Guardian , scientists have confirmed that the island vanished after comparing satellite images of the French Frigate Shoals — a protected marine area in the northwestern Hawaiian Islands. “I uttered a swear word. I had a ‘holy cow!’ moment, somewhat in disbelief that it had disappeared,” said Chip Fletcher, a professor of earth sciences at the University of Hawaii. “The island was probably one to two thousand years old, and we were only there in July, so for it to be lost right now is pretty bad luck.” Related: Mount Kilauea transforms Hawaii’s coastline with the birth of a new island Fletcher and his colleagues were researching East Island via drone devices and sand and coral samples. They were trying to determine the age of the island and determine its future, particularly in regard to climate change. Fletcher said that they wanted to monitor the island and are disappointed that it is gone; however, they have learned that the islands are more at risk than previously thought. East Island was only a half-mile long and 400 feet wide, but it was the second-largest island in the French Frigate Shoals. Even though it was small, the island was an important ecosystem for local wildlife. The critically endangered Hawaiian monk seal used East Island to raise their young. Threatened green sea turtles and albatrosses also depended on East Island for survival. In the right conditions, an atoll like French Frigate Shoals is always at risk when a hurricane hits. But  climate change is warming the ocean and atmosphere, leading to more powerful and frequent storms. Fletcher said the loss is a huge blow, and the team did not expect the island to disappear that quickly. Randy Kosaki, a senior official for the Hawaii monument at NOAA, said that the “take-home message” is that climate change is real, and it is happening right now.

Zigzagging green terraces make up a luxury residential block in Mexico City

Comments Off on Zigzagging green terraces make up a luxury residential block in Mexico City

A challenging hillside site in Mexico City has given rise to Alcázar de Toledo, a luxury residential development designed by Sordo Madaleno Arquitectos to look like an extension of its lush landscape. Embedded into the rugged terrain, the five-unit apartment block is made up of a series of green terraces that zigzag up the slope and provide deep roof overhangs to the bands of glass that wrap around the residences. In addition to its striking and sculptural form, the 5,471-square-meter building also affords spectacular panoramic views of the city. Completed in 2018, Alcázar de Toledo consists of four levels. The parking spaces are located on the topmost floor that descends via ramp down 5 meters to the reception and lobby with views of a large wooded area as well a water focal point with fountains. The five apartment units are spread out across the remaining floors, with two 500-square-meter properties on the level below parking; a 700-square-meter unit on the floor below; and two more 500-square-meter apartments placed on the lowest level. The different sizes of each unit translate to different programming and range from two to four bedrooms. A pool , spa, gym, terrace, dressing rooms and bathrooms are located on the second level from the bottom. “The architectural concept is based on a linear element, which folds itself over the topography in a right-angled zigzag shape,” the architects explained. “Each fold responds to different needs and contains the spaces for the five departments, with large terraces , amenities and parking. This resulting piece of four levels, as it adapts to the ground, is transformed into a structure element (like a wall or slab) or an open plaza or terrace. A solution that creates an elegant and subtle shape with a clear horizontality between the native vegetation of the context.” Related: A lush rooftop oasis flourishes on this renovated Art Deco townhouse in Mexico City Natural light and ventilation are maximized through the interiors, which all feature tall ceilings, open-plan common areas and full-height glazing shaded by the overhanging green roofs. Rainwater is also harvested, treated and reused on site for irrigation. The rainwater cistern is located beneath the building. + Sordo Madaleno Arquitectos Photography by Jaime Navarro via Sordo Madaleno Arquitectos

Comments Off on Kroger plans plastic bag phase-out by 2025

The Kroger supermarket conglomerate announced on Thursday that it is planning a phase-out of plastic bags at all store locations as part of its Zero Hunger | Zero Waste commitment . The company owns more than 2,700 stores throughout 35 states, including popular chains such as Harris Teeter, Fred Meyer and Ralphs. Related: UK bag tariff halves plastic bag marine litter, reduces sales of plastic bags by 86% Kroger is making a “bold move that will better protect our planet,” according to CEO Rodney McMullen. “We listen very closely to our customers and our communities, and we agree with their growing concerns,” added Executive Vice President and COO Mike Donnelly in a press release. Seattle’s QFC grocery stores will be the first of Kroger’s chains to fully eliminate plastic bags, achieving the goal as early as next year. “Starting today at QFC, we will begin the transition to more sustainable options. This decision aligns with our Restock Kroger commitment to live our purpose through social impact,” announced Donnelly. Between the Zero Hunger | Zero Waste and the Restock Kroger commitments, the company hopes to divert 90 percent of waste from landfills by 2020 and provide food to families and individuals in need. Last year alone, the conglomerate sent more than 91 million pounds of safe, nutritious food to local food banks and homes, providing over 325 million meals in total. In 2017, 66.15 million pounds of plastic and 2.43 billion pounds of cardboard were recycled. Kroger, however, wants to achieve more. Related: Starbucks ditches plastic straws for the environment Estimates suggest that less than five percent of plastic bags are recycled annually in America and nearly 100 billion are thrown away each year. Single-use plastic bags are the fifth most common plastic pollutant, harming waterways and marine ecosystems. Harmful microplastics result from the breakdown process and have made their way into soils, waters, air, and nearly everything we ingest. That’s why Kroger, rather than merely lessening the number of plastic bags, plans to eliminate them completely by providing reusable, recyclable multi-use bags. Kroger joins companies such as Starbucks, McDonald’s and the Marriot International Group in a stand to eliminate single-use plastics, which follows legislation banning them in states such as Hawaii and California. + CNN + Kroger + NPR Image via Pixabay
