Climate

Boston Globe reporter Scott Kirsner spotlights Boston as a potential leader in climate technology for their “incubator spaces like Greentown Labs in Somerville and The Engine in Cambridge.”

Prof. Steven Barrett speaks with New York Times reporter Paige McClanahan about the pressing need to make air travel more sustainable and his research exploring the impact of contrails on the planet’s temperature. “Eliminating contrails is quite a big lever on mitigating the climate impact of aviation,” said Barrett.

A new study by MIT scientists finds that Earth can self-regulate its temperature thanks to a stabilizing feedback mechanism that works over hundreds of thousands of years, reports Troy Farah for Salon. “The finding has big implications for our understanding of the past, but also how global heating is shaping the future of our home world,” writes Farah. “It even helps us better understand the evolution of planetary temperatures that can make the search for alien-inhabited exoplanets more fruitful.”

MIT and Delta airlines are developing a plan to eliminate persistent contrails, reports Susan Tran for NBC Boston 10. “A possible solution here is to get rid of these clouds flying at different altitudes,” says Tran. “They [researchers] say that up to 90 percent of all contrails could be avoided by flying at different heights.”

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."

Prof. Tanja Bosak speaks with Science reporter Eric Hand about how scientists plan to study rock samples from Mars for clues as to whether the planet once had a magnetic field and for signs of ancient life, such as the tough lipid molecules that can form cell walls. “You hope for an outline of a cell,” she says. “You will never find peptides and proteins, but lipids can persist.”

Siblings Gia Schneider ‘99 and Abe Schneider SM ‘03 co-founded Natel, a company dedicated to developing sustainable, climate-resilient hydropower, reports Amy Gunia for TIME. “The siblings hope that what they’re doing can help demonstrate a more sustainable approach to renewable energy – proving that companies shouldn’t have to choose between what’s good for the environment and what works economically,” writes Gunia.

Writing for The Conversation, John Reilly, co-director emeritus of the MIT Joint Program on the Science and Policy of Global Change, outlines a roadmap for how the U.S. can meet the Biden administration’s commitment to reducing carbon emissions 50% by 2030 below 2005 levels. “By exploiting declining costs of zero- and low-carbon energy sources in a more aggressive and focused way, the U.S. can meet its target within eight years,” writes Reilly, “all while substantially reducing its dependence on fossil fuels, including high-priced gasoline, and cutting back the air pollution, climate and health impacts resulting from their combustion.”

Prof. Kerry Emanuel speaks with AP reporter Seth Borenstein about the upcoming hurricane season and his research showing an increase in Atlantic storms over the past 150 years.

In an article for The Hill, Prof. Emeritus Henry Jacoby writes that “government agencies, even as they act to protect U.S. interests, need to try to maintain conditions favorable for international climate research efforts.”

A study conducted by Prof. Susan Solomon and her colleagues has found that unlike CFCs, smoke destroys the ozone in a more roundabout way, creating concerns due to the impact of the Australian bushfires of 2019-2020, reports Krystal Vasquez for EOS. “Because of the sheer scale of the event [the Australian bushfires] massive amounts of smoke penetrated the normally pristine upper stratosphere,” writes Vasquez.

Mashable reporter Emmett Smith spotlights how MIT researchers have developed a new technique to clear dust from solar panels without using water. The new method uses “electrostatic repulsion, where an electrode that glides above the panel electrically charges dust particles and subsequently repels them.”

MIT engineers have developed a new contactless method to clean solar panels that could save billions of gallons of water, reports Anuradha Varanasi for Popular Science. “I was amazed at the sheer amount of pure water that is required for cleaning solar panels,” says Prof. Kripa Varanasi. “The water footprint of the solar industry is only going to grow in the future. We need to figure out how to make solar farms more sustainable.”
