Researchers at MIT’s Department of Aeronautics and Astronautics and Delta Air Lines are working together to find new ways to eliminate persistent contrails, the white clouds that trail behind airplanes, using an algorithm that predicts altitudes and locations where contrails are likely to form, reports Omose Ighodaro for Bloomberg. “The joint research group has already completed more than 40 testing flights and has plans for live experiment flights and simulations,” writes Ighodaro.
Prof. Kerry Emanuel discusses the impact climate change has on hurricanes, reports Robinson Meyer for The Atlantic. “First of all, you can have more intense hurricanes in a warmer climate. That finding goes back well over 30 years now,” says Emanuel. “For that reason we expect to see more of the highest-category storms—the Cat 3s, Cat 4s, Cat 5s, more of the Ian-style storms.”
Prof. Kerry Emanuel speaks with Newsweek reporter Pandora Dewan about Hurricane Ian and its correlation to climate change, reports Pandora Dewan for Newsweek. “What worries people in my profession is the confluence of two trends," says Emanuel. "One is demographic, one is nature. The number of people exposed to hurricanes has tripled since 1970 [as] people are moving in droves to hurricane-prone regions. Then the climate is changing, and that is demonstrably increasing the incidence of high-end storms like Ian."
Katie Rae, CEO of The Engine, an entity created by MIT to help support tough tech startups, speaks with Akshat Rathi of Bloomberg about the importance of investing in climate technology. “We have fundamental risks that, if we don’t tackle with real deep science and engineering, that will take us a full step forward, or two steps forward, we’re in trouble,” says Rae.
Prof. Esther Duflo speaks with New York Times reporter Peter Wilson about how climate change can impact global inequality. “The responsibility for the emissions that lead to climate change rests mainly with rich countries and their consumers, but the cost is mainly going to be borne by citizens in poor countries,” says Duflo.
Researchers from MIT’s Research Laboratory for Electronics have developed a portable desalinator that can turn seawater into safe drinking water, reports Ian Mount for Fortune. Research scientist Jongyoon Han and graduate student Bruce Crawford have created Nona Technologies to commercialize the product, writes Mount.
Researchers from MIT, the University of Southern California, Redfin, and the National Bureau of Economic Research found that property listings with flood risks were less likely to be looked at and bid on by potential homebuyers, reports Leslie Kaufman for Bloomberg.
Principal Research Scientist Randolph Kirchain, co-director of the Concrete Sustainability Hub, speaks with Jane Margolies of The New York Times about how the Inflation Reduction Act expands eligibility for tax credits for installing emissions-reduction equipment at manufacturing plants. “These credits are really valuable to keep technology coming down in cost,” says Kirchain.
Writing for Bloomberg News, Prof. Carlo Ratti and Robert Muggah of the Igarapé Institute make the case that cities should use venture capital strategies to manage risk and spur innovation. “To do so, local governments need to change their approach to procurement,” they write. “If administrators pay more close attention to what venture capital can teach them, then the city — one of the first, greatest ventures in human history — will be able to continue to invest in a shared, prosperous tomorrow.”
Hessam Azarijafari, incoming deputy director of the MIT Concrete Sustainability Hub, Ronnen Levinson of Lawrence Berkeley National Laboratory and Andrew Laurent of the Concrete Sustainability Hub write for The Hill about how cities can combat extreme heat by implementing more reflective pavements. “To protect vulnerable communities, federal and local officials must cool cities with high-reflectance pavements before the opportunity to limit the impacts of global warming vanishes,” they write.
Researchers from the MIT Energy Initiative have found that “without restrictions on carbon-dioxide emissions, the Northeast will have even higher per-kilowatt emissions from electricity generation in 2050 than it does now,” reports Justin Fox for Bloomberg. Fox writes that the “modeling results are an indication that the Northeast faces unique challenges in decarbonizing.”
This summer’s heat waves and droughts have brought forth a series of issues including disruption of crop production, further inflation, and electrical issues, reports Colin Lodewick for Fortune. “I think it’s too early to quantify, but I have no doubt that these extreme events are contributing to high prices,” says Sergey Paltsev, deputy director of MIT’s Joint Program on the Science and Policy of Global Change. “In the future, if we don’t change the course of action, it’s going to be worse.”
Prof. Mircea Dincă and Grama Sorin co-founded Transaera, a company dedicated to designing air conditioners that require significantly less energy, reports Scott Kirsner for The Boston Globe. “Grama and Dincă cofounded Transaera in 2018 and supported their early work with about $2 million in state and federal grants, from agencies that included the Massachusetts Clean Energy Center,” writes Kirsner.
The Emerald Tutu, a climate resiliency project in Boston led by Gabriel Cira ’08, is developing a system of floating wetlands designed to reduce coastal flooding by knocking down waves, reports Hannah Chanatry for WBUR. The Emerald Tutu was the winning project at the 2018 MIT Climate Changed Ideas competition. “Fundamentally, it’s like a giant sponge that fits around urban coastlines like we have here in Boston,” said Cira. “It buffers those coastlines from the intense effects of coastal storms.”
Los Angeles Times reporter Sammy Roth spotlights Prof. Lawrence Susskind’s study that finds common sources of opposition to delayed or blocked renewable energy projects include concerns over land use and environmental impact. Roth writes that Susskind’s “research has convinced him that speeding up the clean energy transition will be possible only if developers take the time to make a good-faith effort to gather input from communities before dumping solar and wind farms on them.”
