Climate twins: which city will your city feel like in 2080?

The phrase “global warming” gets tossed around a lot, but do we really understand what it means and how it will feel? In the groundbreaking Paris Agreement, 195 countries agreed to limit global warming to 2 degrees Celsius — but how will those 2 degrees really affect our lives? A new study in Nature links 540 U.S. cities to other cities with a current climate that is similar to how those cities will feel in 60 years. As CityLab’s Robinson Meyer explained , the study takes each city and finds “the city whose modern-day weather gives the best clue to what conditions will feel like in 2080.” The researchers’ goal is to translate what abstract climate science and meteorological changes really mean for people by making them understandable in a modern — and personal — context. For example, Philadelphia will feel more like Memphis in 2080. That equates to summer days that are warmer by an average of 7 degrees Fahrenheit, and winters that are warmer by 10 degrees. Memphis, on the other hand, will feel more like College Station, Texas.  Use this web tool to find your city’s ‘climate twin’. The ‘Arkansas-ification’ of U.S. cities “Every place is getting warmer and many are getting drier,” Matthew Fitzpatrick, author of the study, told CityLab. In fact, most cities’ future climate twin is approximately 500 miles farther south and toward the middle of the country. “In the Northeast, you can envision the future as one big Arkansasification,” Fitzpatrick explained. For those who haven’t been to Arkansas, the authors explained that means more humid, subtropical climates typical of the southeast and Midwest. Western cities, however, will start to feel more like the desert conditions of Southern California and the southwest. The cities selected in the study cover 250 million urban Americans. By using a method called climate analog mapping, the authors used different emission scenarios and weather predictions to find all similar cities, and then narrowed down the options to find the best match based on statistical and topographical similarities. The 540 cities selected were those that had the strongest match and the most relatable “twin.” A lot can happen in 60 years, and most are still hopeful that we can make changes to curb climate change. The authors used different examples of carbon emission rates, called Representative Concentration Pathways, to compare the results based on our best- and worst-case scenarios. For example, if progressive policies are put in place soon to curtail carbon emissions, Washington D.C. might feel like Paragould, Arkansas by 2080. If mitigation policies are not put into place, however, D.C. will become more like Greenwood, Mississippi — an additional 200 miles south. D.C. residents are already familiar with hot, humid summers in the low-lying capitol, so the news that their children will face even stickier summers is lamentably relatable. Though the matches aren’t perfect, the authors explained they do give modern-day examples that make abstract climate change realistic and easier to understand. Climate change puts cities at risk Cities are especially vulnerable to climate change, with rapidly increasing populations, urban sprawl, aging infrastructure and limited budgets for forward-thinking climate adaptation. In New York City , where heat island effect (the intensification of heat by concrete, urban environments) is already a major problem, the thought of becoming Jonesboro, Arkansas is daunting. Imagine a stifling hot, underground subway platform well above 85 degrees in July with no breeze. Now add an average of 9 degrees Fahrenheit. Related: Reimagine a resilient future for your city with this nature-based tool But human discomfort isn’t the only problem. These shifts in climate also affect other species. Migratory bird patterns are already changing but so are insect populations . Increased humidity, flooding and temperatures cause an uptick in mosquitoes, ticks and flies. This means an increase in diseases such as zika and dengue that were previously contained to fewer states. Winter freezes that used to kill off larva may no longer be cold enough to have the same population-controlling effect. Climate changes we can understand For most urban dwellers, this alarming news of hotter days and health consequences is not new. However, the authors of the study are hopeful that these results help people conceptualize climate change and make discussions more relatable. Their assessment is “place-based” and aims to use cities that are familiar. Many people have visited these cities, know about them or at the very least have an idea what the weather in their future “twin” city is like compared to where they live. Framing the discussion about climate impacts in a way that is understandable — and in some cases so real you can almost feel it — is critical. Hopefully, these terms and tools help people understand the urgency at a global scale in terms that are meaningful at a personal level. Via CityLab Image via Pixabay

173 countries agree to slash shipping industry emissions in historic deal

Comments Off on 173 countries agree to slash shipping industry emissions in historic deal

Shipping was the sole industry excluded from the 2015 Paris Agreement , even though the sector’s annual carbon emissions are higher than those of Germany  — and countries now plan to address that. 173 nations just agreed to a historic, mandatory deal to slash shipping industry emissions . Related: World’s first autonomous shipping company launched in Norway One week of negotiations at an International Maritime Organization (IMO) meeting in London yielded this landmark deal. Envoys of 173 countries agreed to reduce emissions at least 50 percent from 2008 levels by 2050. Russia, Saudi Arabia, and the United States objected. Shipping vessels tend to burn fuel oil, which is cheap but also one of the dirtiest fossil fuels . According to Bloomberg , the industry didn’t factor into the Paris agreement because each participating country presented its own plans to curb emissions, excluding the seas. University College London Energy Institute reader Tristan Smith told Bloomberg, “It is likely this target will tighten further, but even with the lowest level of ambition, the shipping industry will require rapid technological changes.” BREAKING: Commitment to decarbonise shipping is welcome – governments can no longer shirk decisions on how to cut ship GHG emissions https://t.co/7Bh4pWIO04 pic.twitter.com/mEp3t36zSM — Transport & Environment (@transenv) April 13, 2018 “Making new ships emit less CO2 is the most obvious way to decarbonize the sector because ships have long lifetimes, usually around 25 to 30 years,” shipping officer Faig Abbasov of European NGO Transport & Environment told Bloomberg. “If you don’t build ships more efficiently, those ships will still be sailing around in the middle of the century.” As with the Paris Agreement , some people are saying this new deal doesn’t go far enough. A statement from the Clean Shipping Coalition (of which Transport & Environment is a member) said the target set “falls short of the 70 to 100 percent cut by 2050 that is needed to align shipping with the goals of the Paris Agreement.” Transport & Environment shipping director Bill Hemmings said, “The IMO should and could have gone a lot further but for the dogmatic opposition of some countries led by Brazil, Panama, Saudi Arabia. Scant attention was paid to US opposition.” + Clean Shipping Coalition Statement Via Bloomberg Images via Depositphotos ( 1 , 2 )

Comments Off on Media lab built from recycled shipping containers pops up in half a day

Four recycled shipping containers have found a new lease on life as Bard College’s new media lab in upstate New York. Quick, affordable, and modern, MB Architecture’s speedy lab solution for the Bard College Department of Experimental Humanities has the added benefit of a folding glass door that blurs the boundary between indoors and out. Prefabricated offsite, the Bard College Media Lab was installed in just half a day and fully operational within a few weeks. Located in the middle of campus near a Frank Gehry concert hall, the 960-square-foot media lab cost slightly over $200,000 for prefabrication , delivery, and installation. The four shipping containers were stacked into a single blocky monolith with the exterior painted matte black. While the corrugated sides were retained—perhaps as a reminder of the building’s industrial past—large glazed panels punctuate the building to bring in views of the outdoors and create the illusion of spaciousness inside. Related: The Coolest Bar in Texas is Built With Seven Stacked Shipping Containers Flexibility was built into the design of the lab, which will be shared by different college departments. The first floor comprises multiple entrances, a bathroom, and a double-height meeting room that opens up to the quad through a large pivoting garage door. By opening up the interior to the outdoors, the room can be used as a stage for performances, concerts, and theatrical events. An office is located on the second floor. + MB Architecture Via ArchDaily Images © Matthew Carbone

Scientists uncover hidden Mayan city of 10M people in Guatemala

Comments Off on Scientists uncover hidden Mayan city of 10M people in Guatemala

An international team of researchers have identified tens of thousands of previously unknown Mayan structures using a high-tech aerial mapping technology known as Lidar. Discovered in the jungles of Guatemala , the ancient structures include homes, pyramids, defense installations, large-scale agricultural fields, and irrigation canals, suggesting that up to 10 million people lived in the area at its peak. “That is two to three times more [inhabitants] than people were saying there were,” Marcello A Canuto, a professor of anthropology at Tulane University, told The Guardian . Those that did live there clearly altered the landscape far more dramatically than previously thought. The research team, which includes scientists from the United States , Europe, and Guatemala working in collaboration with Guatemala’s Mayan Heritage and Nature Foundation , used Lidar, which stands for light detection and ranging, to virtually cut through the thick jungle . Lidar works by bouncing pulsed laser light off of the ground to unveil contours otherwise hidden. In addition to its use in archaeology, lidar also serves to assist the control and navigation of self-driving cars. Further areas of lidar application include seismology, laser guidance, and atmospheric physics. Related: Hidden passageway discovered at ancient Mayan ruins The recent discoveries in the Peten region of Guatemala have shown that in some areas of the now-thick jungle, up to 95 percent of land was used for agriculture . “Their agriculture is much more intensive and therefore sustainable than we thought, and they were cultivating every inch of the land,” Francisco Estrada-Belli, research assistant professor at Tulane University, told The Guardian . To do so, the Mayans drained swampland that even today is considered unfit for farming. The large scale of the projects demonstrates the coordinated effort required to complete them. “There’s state involvement here, because we see large canals being dug that are re-directing natural water flows,” Thomas Garrison, assistant professor of anthropology at Ithaca College in New York, told The Guardian . Despite the discovery’s massive size, it would have likely remained unknown without Lidar technology. “I found [an ancient road],” explained Garrison, “but if I had not had the Lidar and known that that’s what it was, I would have walked right over it, because of how dense the jungle is.” Via The Guardian Images via Ithaca College and Depositphotos

Living solar panel wallpaper harvests energy thanks to photosynthesis

Comments Off on Living solar panel wallpaper harvests energy thanks to photosynthesis

Researchers created an incredible  energy-harvesting wallpaper by inkjet-printing circuitry and cyanobacteria on paper. The cyanobacteria lived through the printing process, and then performed photosynthesis to harvest power. Imperial College London described the product as a two-in-one solar bio-battery and solar panel , and said an iPad-sized piece of the wallpaper could energize a digital clock or LED light bulb. Imperial College London, University of Cambridge , and Central Saint Martins researchers worked together on the project. They utilized cyanobacteria as ink, printing the bacteria with an inkjet printer onto electrically conductive carbon nanotubes , which had also been inkjet-printed on the paper, according to Imperial College London . The cyanobacteria – still alive – performed photosynthesis, allowing the bio-solar panel to harvest electrical energy. Related: Brilliant conductive wallpaper shows the energy running through your walls The researchers think there could be several applications for their living wallpaper. Marin Sawa of Imperial College London said in a statement, “Imagine a paper-based, disposable environmental sensor disguised as wallpaper, which could monitor air quality in the home. When it has done its job it could be removed and left to biodegrade in the garden without any impact on the environment.” The research offers a development in microbial biophotovoltaics (BPV) technology , exploiting “the ability of cyanobacteria and other algae that use photosynthesis to convert light energy into an electrical current using water as the source of electrons,” according to Imperial College London. Cyanobacteria can not only generate electricity during the day, but at night as well, from molecules they produced in daylight. BPVs can be difficult to scale up – two obstacles being expense and lifespan – but the team’s use of an off-the-shelf inkjet printer could allow them to scale up the technology easily. Andrea Fantuzzi, also of Imperial College London, said paper-based BPVs wouldn’t be used to produce solar power on a large scale, “but instead could be used to construct power supplies that are both disposable and biodegradable. Their low power output means they are more suited to devices and applications that require a small and finite amount of energy, such as environmental sensing and biosensors .” The journal Nature Communications published the research online yesterday.

Megacities could save $505 million a year thanks to trees

Comments Off on Megacities could save $505 million a year thanks to trees

Trees offer enormous monetary benefit to megacities , or those urban areas where over 10 million people reside. New research led by Theodore Endreny of SUNY’s College of Environmental Studies and Forestry highlights the idea that cities shouldn’t overlook the immense value of these plants: every year they could offer a payoff of $482 million in lowered air pollution , $11 million in stormwater remediation, $8 million in carbon dioxide sequestration , and $500,000 savings on heating and cooling costs. The researchers looked at Los Angeles, Beijing, Tokyo, Mumbai, Buenos Aires, Moscow, London, Istanbul, Mexico City, and Cairo. They built on estimates from the i-Tree model developed by the United States Forest Service , which analyzes environmental benefits from trees, with local data. They found median tree cover in all the cities was 21 percent, with potential tree cover at 19 percent. Tree cover varies by megacity – for example, in Cairo tree cover is just 8.1 percent while in Moscow it’s 36 percent. Tokyo claims the prize for greatest tree canopy cover per person, according to CityLab. Related: California street trees are worth $1 billion, says USFS and UC Davis The benefits each megacity reaps from trees varies some as well. Cairo doesn’t receive much precipitation so they don’t benefit that much from stormwater remediation. And Mumbai’s energy expenditures aren’t as high as other megacities’ so it doesn’t benefit as much in that area. Los Angeles got the most benefit from trees sequestering carbon dioxide. The researchers suggest cities plant more trees to nearly double the benefits gleaned from the leafy canopies. And as nearly 10 percent of humans live in megacities, the move could serve millions of people. The journal Ecological Modelling made the research available online at the end of July. Six researchers at the State University of New York College of Environmental Science and Forestry and the Parthenope University of Naples contributed to the study.

How orange peels helped barren land in Costa Rica spring back to life

Comments Off on How orange peels helped barren land in Costa Rica spring back to life

There’s more to oranges than juice! Back in the 1990’s, two ecologists suggested orange juice manufacturer Del Oro donate some of their land near a national park in Costa Rica ; in exchange, they’d be able to deposit agricultural waste for free on degraded land inside the park. Del Oro agreed and dumped 1,000 truckloads of orange pulp and peels on the land. Today, that area is a thriving forest . A Princeton University -led team of researchers journeyed to the forest to discover just how much that food trash transformed the forest – and how other businesses might do the same. Del Oro donated land to Área de Conservación Guanacaste at the suggestion of husband and wife ecologist team Daniel Janzen and Winnie Hallwachs, who’d worked as advisors at the park. The company unloaded around 12,000 metric tons of orange waste for biodegradation until rival company TicoFruit sued, saying Del Oro had defiled the park. TicoFruit won and the land went largely overlooked for over a decade. Related: 16-year-old South African girl invents drought-fighting super material from orange peels Years later, environmental researchers decided to evaluate the site. They discovered a lush forest that had a 176 percent increase in aboveground biomass – what Princeton described as the trees’ wood – in the seven acres they studied. They also found a difference between areas where orange peels hadn’t been dumped and where they had – according to Princeton, the latter showed richer soil, greater tree-species richness, and more closure in the forest canopy. The researchers think regenerating forests with agricultural waste could help us sequester carbon . Princeton graduate student Timothy Treuer said in a statement, “This is one of the only instances I’ve ever heard of where you can have cost-negative carbon sequestration. It’s not just a win-win between the company and the local park – it’s a win for everyone.” Princeton University ecologist David Wilcove thinks more businesses could help the environment in similar ways. He said while companies do generate environmental problems, “…an awful lot of those problems can be alleviated if the private sector and the environmental community work together. I’m confident we’ll find many more opportunities to use the leftovers from industrial food production to bring back tropical forests. That’s recycling at its best.” University of Pennsylvania , Beloit College , and University of Minnesota scientists joined the Princeton researchers to write a study published by the journal Restoration Ecology this week.

US DOI scientist claims he was reassigned for speaking up on climate change

Comments Off on US DOI scientist claims he was reassigned for speaking up on climate change

Is the Donald Trump administration reassigning employees who speak out on the dangers of climate change ? Joel Clement, former Office of Policy Analysis director at the Department of the Interior (DOI), seems to think so. He penned an opinion piece for The Washington Post saying he was moved into an “unrelated job in the accounting office.” He said he’s a scientist and policy expert, not an accountant – “…but you don’t have to be one to see that the administration’s excuse for a reassignment such as mine doesn’t add up.” Clement said he began working in the DOI almost seven years ago, and worked with communities in Alaska to help them prepare for the impacts of climate change. On June 15, he received a letter informing him of his reassignment to “improve talent development, mission delivery and collaboration.” He was one of around 50 senior employees to receive a letter, and was shuffled to the role of senior adviser in the Office of Natural Resources Revenue – an office he said gathers royalty checks from fossil fuel companies. Related: Trump launches “witch hunt” for government employees who worked on climate change policy Clement’s background is not in accounting. He has a Master of Environmental Studies degree in Forest Sciences and Canopy Biology from The Evergreen State College . But he said he spoke out on the challenges stemming from climate change that Alaska Native communities face in the months before his reassignment, even bringing the threat up with White House officials. Clement said in his op-ed, “It is clear to me that the administration was so uncomfortable with this work, and my disclosures, that I was reassigned with the intent to coerce me into leaving the federal government.” Indeed, a few days following his reassignment, new Interior Secretary Ryan Zinke testified before Congress that reassignments might be used to eliminate employees. Clement suggested Zinke might think fed-up employees might quit, and said he has colleagues who are being moved to other locations in the country, at taxpayer expense, to jobs that don’t align well with their skill set. Clement said the Kivalina, Shishmaref , and Shaktoolik villages are “one superstorm from being washed away.” He wrote, “I believe that every president, regardless of party, has the right and responsibility to implement his policies. But that is not what is happening here. Putting citizens in harm’s way isn’t the president’s right…The threat to these Alaska Native communities is not theoretical. This is not a policy debate.” Read Clement’s full piece here . Via The Washington Post Images via Wikimedia Commons and screenshot
