After 13 months of collecting data, history’s largest  Arctic  research expedition returned with grim news. “We witnessed how the Arctic Ocean is dying,” mission leader Markus Rex told Agence-France Presse. “We saw this process right outside our windows, or when we walked on the brittle ice.” In September 2019, the research mission set sail on the German Alfred Wegener Institute’s Polarstern ship from Tromsø, Norway. For 13 months, about 300  scientists  from 20 countries were on board at various times. Known as the  MOSAiC  Expedition — Multidisciplinary Drifting Observatory for the Study of Arctic Climate — the team followed in the footsteps of Fridtjof Nansen’s 1893-1896 journey. But instead of traveling aboard an old wooden sailing ship like Nansen’s Fram, MOSAiC traveled via the Polarstern, a highly modern icebreaker designed for research. Related: Arctic wildfires are emitting 35% more carbon compared to 2019 The international scientists gathered information to better understand how the Arctic is weathering the climate crisis. Rex described this area as “the epicenter of  climate change .” The crew hopes that the finding will help predict how heatwaves, storms, floods and fires will affect the Arctic’s future. The  researchers  brought back over 1,000 ice samples and 150 terabytes of data about subjects such as Arctic clouds, biology, atmosphere, and ocean physics. It will take years, or even decades, to analyze all this intel. “We went above and beyond the data collection we set out to do,” said Melinda Webster, a sea ice expert from the University of Alaska, Fairbanks. Unfortunately, the expedition’s initial impressions of the situation were severe. “At the North Pole itself, we found badly eroded, melted, thin and brittle ice,” said Rex. The researchers experienced smooth sailing in some areas previously covered with  ice . Rex predicts that Arctic summers will soon be ice-free if the planet’s warming trend continues. The Polarstern’s Arctic voyage cost $177 million.  Coronavirus  upended the trip’s logistics, forcing scientists to end the mission earlier than planned. Via EcoWatch and Science Image via Pixabay

Global design firm Skidmore, Owings & Merrill (SOM) has unveiled designs for Jiuzhou Bay, a new 5.6 million-square-foot mixed-use neighborhood in coastal Zhuhai, which was recently named China’s most livable city by the Chinese Academy of Social Sciences. Selected from a shortlist of 10 global design firms, SOM’s proposal targets a low-carbon scheme that makes use of the region’s abundant natural resources — the sea and the sun — to generate renewable energy and reduce the development’s environmental footprint. Located in China’s southern Guangdong province in the Pearl River Delta, Zhuhai is a burgeoning tech hub with a reputation that has been recently elevated by a connection to the international finance and tourism centers Hong Kong and Macau via the longest sea-crossing bridge in the world. The new development will be a beacon for sustainable growth in the tech-heavy region that the architects say may soon rival Silicon Valley. The proposed Jiuzhou Bay development will include state-of-the-art office spaces, residences, retail and infrastructure, such as a robust transportation hub that offers connections to land, sea and rail across more than 40 acres. Related: Historic Zhuhai sugar factory to be reborn as a low-carbon cultural hub The city’s maritime history has also greatly informed the architects’ design decisions, particularly with the five modular canopies that wrap around the three sides of a 1.8 million-square-foot port to form a series of covered pedestrian alleyways, a lively retail environment and interlinked courtyards along the waterfront. Solar panels and rainwater harvesting systems would be integrated into the canopies. The masterplan also includes a lighthouse-inspired skyscraper with offices, a 20-story Ritz Carlton hotel , a sky bar and an observation deck. “The forms of the canopies are inspired by the local legend of the Fisher Girl and reflect the fishing nets commonly seen on the coastline throughout the region,” said Sean Ragasa, design director at SOM. “We wanted our design to resonate with the culture and history of Zhuhai, and to evoke a story that’s familiar to everyone who lives there.” + SOM Images via SOM

Near the border of Ohio and Kentucky, a stunning sustainable home has hit the market for $3,249,000. Designed by local architect Jose Garcia , the home was built with natural materials, from the exterior cladding of cedar and cypress wood to the interior use of century-year-old reclaimed Douglas fir. The Douglas fir was sourced from a demolished cotton mill and used for the ceiling and walls. The Cincinnati home is in the process of obtaining LEED platinum certification and boasts 38 solar panels on the roof, a geothermal energy system and a smart home system for optimizing energy efficiency. Located at 1059 Celestial Street, the custom, single-family home in the city’s Mt. Adams suburb spans 6,778 square feet on a quarter-acre lot with four bedrooms, three-and-a-half baths and a three-car garage. The home’s elevated location allows for stunning views of downtown Cincinnati as well as the Ohio River, which marks the boundary between Ohio and Kentucky. A rooftop deck with a fire pit and a vegetable garden bed takes advantage of these panoramic views. The main bedroom, which is bathed in light by a skylight, connects to a bridge that leads directly to the rooftop deck.  Related: Architecture students design and build a LEED Platinum smart home in Kansas Natural light and a sense of spaciousness define the interiors of the modern home, which is centered on an atrium . The atrium allows for direct sight lines from the entrance to the pocket sliding glass doors, which open up to a 45-foot-long balcony along the entire side of the home. Full-height windows, a natural materials palette and a courtyard garden also help to usher the outdoor landscape indoors, while tall ceilings and an open-plan layout direct views toward downtown Cincinnati. The abundance of wood that lines the interior is complemented by exposed brick and concrete in parts of the home. The kitchen cabinetry, designed by the architect, is bleached European White Oak and paired with white quartzite countertops. To meet LEED Platinum standards, double-pane windows imported from Luxembourg were installed throughout the residence. Two geothermal wells were drilled beneath the driveway to provide an additional energy source to solar, which collected from the solar array on the front part of the roof. In addition to home automation, the building is equipped with an air-purifying system that filters air in the entire home. The property is listed with Coldwell Banker . + Jose Garcia Design Images via Coldwell Banker

Greenland ice sheet loses record amount of ice in 2019

Comments Off on Greenland ice sheet loses record amount of ice in 2019

According to new satellite data analysis by a group of scientists, the Greenland ice sheet lost ice at a rate of 1 million metric tons per minute in 2019. This is the highest rate of ice melt recorded in Greenland. The findings were published in the journal Communications Earth & Environment and revealed that the Greenland ice sheet shrank by 532 billion metric tons in 2019 alone. The high rate of Greenland’s ice melt is attributed to the effects of climate change. The report shows that temperature rise in the Arctic has been double that of lower latitudes. This has led to the continued rapid melting of ice into the oceans. It is the melting ice sheets that are contributing the most to the rise in sea levels, posing threats to coastal cities. Related: Greenland’s ice sheet lost 197 billion tons of ice in July An analysis of the data, which dates back to 2003, shows that the amount of ice that melted in 2019 alone is nearly double the annual average since 2003. In past years, the Arctic lost an average of 255 billion metric tons of ice per year, while in 2019, 532 billion metric tons of ice were lost. Although scientists knew that ice loss in Greenland was accelerating, they did not expect the drastic shift experienced in 2019. The scientists behind the study say that the melting experienced last year might be the biggest loss in centuries and possibly millennia. According to Ingo Sasgen of the Alfred Wegener Institute in Bremerhaven, Germany and lead author of the study, the melting rate experienced in 2019 was “shocking and depressing. But it’s also not very surprising, because we had other strong melt years in 2010 and 2012, and I expect we will see more and more.” Last year also saw a lower amount of snowfall, meaning less ice was added as more ice melted. Sasgen said, “The real message is that the ice sheet is strongly out of balance.” + Communications Earth & Environment Via The Guardian Image via Jean-Christophe ANDRE

Trump administration furthers Arctic drilling plan

Comments Off on Trump administration furthers Arctic drilling plan

The Trump administration’s environmental protection rollbacks seem to now come daily. Today’s bad news? A plan to allow  oil  and gas companies to drill in Alaska’s so-far pristine Arctic National Wildlife Refuge. In 2017, a Republican tax bill opened part of the refuge to gas and oil leasing. Monday’s development pushed the plan further, aiming to sell the first drilling leases by the end of 2020. Many Republicans back the plan, despite opposition from environmental groups and Alaska’s Indigenous communities. Related: EPA loosens restrictions on methane emissions The over 19 million-acre refuge has long remained off-limits to development. Managed by the U.S. Fish & Wildlife Service, most of the refuge is true wilderness, free from roads, trails and facilities, and open to the public for exploration. The few travelers who visit access the refuge by private planes and air taxis. Visitors may witness the Polar and grizzly bears , wolves, wolverines, caribou, beluga whales, musk oxen and walruses that call this area home. Though wildlife outnumbers people here, both the Gwich’in and Iñupiat people reside on and live off resources from the land.  Sometimes calling themselves “caribou people,” the Gwich’in have based their culture around these reindeer for centuries. The Gwich’in live in 15 villages across northeast  Alaska  and northwest Canada and have actively fought against gas and oil leasing. David Smith, a Gwich’in leader in Arctic Village, worries that the industries will harm caribou and change his nation’s way of life. “I would say this is like no other place on earth, so we shouldn’t be treated like any other place on earth,” Smith said in an interview with  Alaska Public Media . “I can drive in any direction and  hunt  freely. I can drive in any direction and go trapping.” Despite the recent news, the fight to protect the Arctic National Wildlife Refuge continues. Still, environmental groups say that once companies buy drilling rights, it will be harder for future presidents to stop  Arctic  drilling. “The Trump administration never stops pushing to drill in the Arctic Refuge — and we will never stop suing them,” said Gina McCarthy, president of the Natural Resources Defense Council. “America has safeguarded the refuge for decades, and we will not allow the administration to strip that protection away now.” Via Thomson Reuters Foundation Image via U.S. Fish and Wildlife Service Headquarters

Canada’s last Arctic ice shelf has collapsed

Comments Off on Canada’s last Arctic ice shelf has collapsed

The Milne Ice Shelf, the largest remaining intact ice shelf in Canada, has collapsed. According to researchers studying the Milne Ice Shelf, the ice shelf collapsed in just two days at the end of July and lost about 40% of its area. This ice shelf sits at the fringe of Ellesmere Island in the northern territory of Nunavut. For the past 30 years, the Arctic has warmed twice as fast as the global rate. The Arctic’s warming reached new levels this year, causing polar ice to hit its lowest levels in 40 years. Though ice caps melting in the heat has become more frequent, this year’s record temperatures caused unprecedented melting and disintegration of bigger ice shelves. Related: Antarctica reaches record high temperature “Above normal air temperatures , offshore winds and open water in front of the ice shelf are all part of the recipe for ice shelf break up,” The Canadian Ice Service said on Twitter. The area affected by the ice shelf breaking is significantly large. According to researchers, the shelf area shrank by 80 square kilometers — an area roughly 20 square kilometers larger than New York’s Manhattan Island. “This was the largest remaining intact ice shelf, and it’s disintegrated, basically,” said Luke Copland, a glaciologist at the University of Ottawa and Milne Ice Shelf researcher. The research team lost a campsite and several instruments when the ice shelf collapsed. According to one of the researchers, Derek Mueller of Carleton University in Ottawa , the team has noticed signs of collapse while working on the ice shelf. Mueller says the team was lucky to not be on the ice shelf when it collapsed. Given that the collapse swept away an entire campsite, the team would have faced a similar fate. Researchers now warn that the Arctic can expect more ice melting if global temperatures continue to increase. This year, the Arctic experienced temperatures rising 5 degrees Celcius above the 30-year average. If global warming continues, Arctic ice could melt entirely into the sea over time.

Arctic wildfires rage through Siberia

Comments Off on Arctic wildfires rage through Siberia

The earth’s poles have made the news a lot this summer, and not for good reasons. Now, another awful update has hit, with  Arctic wildfires burning out of control. “We’ve had exceptional and prolonged heat for months now and this has fueled devastating Arctic fires,” said Clare Nullis, World Meteorological Organization (WMO) spokesperson, at a  press conference in Geneva . “And at the same time we’re seeing rapidly decreasing  sea coverage along the Arctic coast.” Related: Siberia hits record 100 degrees Scientists use satellite images to gauge the extent of the wildfires. However, fire’s dynamic nature can make it hard for authorities to track the exact number of fires burning at once. On Wednesday, data indicated “188 probable points of fire.” The worst fire blazed in Russia’s Sakha Republic and Chukotka Autonomous Okrug, in the far northeast reaches of Siberia . “We’re seeing, you know, dramatic satellite images, which show the extent of the burns surface,” said Nullis. “The fire front of the northern-most currently active Arctic wildfire is less than eight kilometres from the Arctic ocean – this should not be happening.” Pollutants found in wildfire smoke include nitrogen oxide, carbon monoxide, solid aerosol particles and volatile organic compounds. The WMO said that Arctic wildfires emitted the equivalent of 56 megatons of  carbon dioxide  this June, up from 53 megatons in June 2019. This year’s persistent heat is caused by what meteorologists call “blocking high pressure aloft.” A blocking high pressure system can linger over an area for a prolonged time, forcing other  weather  systems to go around it. High pressure aloft traps heat by compressing air downward and preventing cooler air from pushing through and bringing the region some relief. “In general, the Arctic is heating more than twice the global average,” said Nullis. “It’s having a big impact on local populations and  ecosystems , but we always say that what happens in the Arctic doesn’t stay in the Arctic, it does affect our weather in different parts of the world where hundreds of millions of people live.” Via AP News and Huffpost Image via Pixabay

Comments Off on This DIY algae kit is an easy science experiment for kids

BioBombola is a DIY algae kit specially designed to teach kids how to grow their own domestic garden of spirulina – a sustainable source of plant-based proteins. The project is the brainchild of ecoLogicStudio’s Claudia Pasquero and Marco Poletto, who wanted to create a fun and educational way to keep their children occupied during the shutdown in London. In addition to cultivating the nutritious blue-green algae, the kit also helps to absorb the same amount of carbon dioxide as two young trees and provides the home with the same amount of oxygen as seven common indoor plants. Perhaps best of all, BioBombola allows children and adults alike to interact with nature from the comfort of their own homes. Related: Eos Bioreactor uses AI and algae to combat climate change The two researchers got the idea after creating an algae-growing and air pollution data collection project with their children, who were already participating in a home-school program. After their experiment has finished, the idea for the mini algae harvesting kit was born. Each kit comes with a nutrients bag, a 15-liter starting batch of living photosynthetic spirulina cells, an air piping system, a pump to keep the medium afloat, a customized photobioreactor and a 1-meter-tall, lab-grade glass container. Not only does the bubbling of the small air pump keep the precious algae constantly stirred and oxygenated, it also creates a soft, calming sound similar to a fish tank. The fresh, cultivated spirulina can be harvested several times a week and collects up to 7 grams of product per day (the daily recommended supplement intake for a family of four, according to the inventors) to be used in food and drinks. The harvesting process is simple and suitable for children, as well. While it is recommended to install the kit in a sunny spot or near a grow lamp, the photobioreactor can adapt to almost any environment. + EcoLogicStudio Photography by NAARO via EcoLogicStudio

Beavers could be contributing to warming in the Arctic

Comments Off on Beavers could be contributing to warming in the Arctic

A recent study published in the journal Environmental Research Letters suggests that beavers’ actions could be contributing to climate change. The study, which involved analysis of high-resolution satellite imagery, has shown that beavers are constructing dams and lakes in the Alaskan tundra. The actions of these beavers are transforming the Alaskan landscape in a way that is dangerous to the environment. When they form new bodies of water, they contribute to the thawing of frozen permafrost, which is a natural reservoir for methane and carbon dioxide. When lakes are formed, these greenhouse gases are likely to leak into the atmosphere. There has been a sharp increase in the number of beavers in the Alaskan tundra in the last two decades. According to the research, scientists have spotted increasing numbers of beavers over a very small area. These beavers carry dead trees and shrubs to create dams, resulting in new lakes that flood the permafrost soil and release methane. Related: Climate change could lead to dramatic decline in narwhals The sudden rise in the number of beavers in the Arctic region has lead to more of these dams. Ingmar Nitze, a researcher from the Alfred Wegener Institute and author of the study, said, “We’re seeing exponential growth there. The number of these structures doubles roughly every four years.” The study found that the number of dams in a 100-square-kilometer area around Kotzebue increased from two in 2002 to about 98 in 2019. This is a staggering 5000% increase in the number of dams. Nitze said that although the lakes can drain themselves and leave dry basins, the beavers are smart enough to block the outlets and refill the basins. CNN reported that the Arctic permafrost is melting at an alarming rate. These natural methane and carbon dioxide reservoirs are releasing large amounts of greenhouse gases into the atmosphere. Several studies are now underway to determine the amount of carbon dioxide being released from such reservoirs. “There are a lot of people trying to quantify methane and CO2 emissions from lakes in the Arctic but not specifically yet from beaver lakes,” Nitze explained. The researchers now fear that similar beaver actions may be happening in other areas as well. Nitze warned that the same could be happening in the Canadian tundra and Siberia among other places in the world. + Environmental Research Letters Via CNN Image via Jan Erik Engan
