Climate

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.”

Prof. Kripa Varanasi, graduate student Sreedath Panath, and a team of researchers are developing a water-free way to clear dust off of solar panels, reports Billy Hurley and Ed Brown for Tech Briefs. “Water is such a precious commodity, and people need to be careful about how to make use of this resource that we have,” says Varanasi. “The solar industry really needs to keep this in mind; we don’t want to be solving one problem and creating another.”

MIT researchers have developed a new water-free system that uses static electricity to clear dust from solar panels, reports Miriam Fauzia for The Daily Beast. “By using this technique, we can recover up to 95 percent of a solar panel’s power output,” explains graduate student Sreedath Panat.

New Scientist reporter Chen Ly writes that MIT researchers have developed a new technique that uses static electricity to remove the dust from solar panels, which could save around 45 billion liters of water annually. “I think water is a precious commodity that is very undervalued,” says Prof. Kripa Varanasi. “What I’m hoping is this will spur more people to think about water issues.”

Prof. Susan Solomon and Eugenia Kalnay PhD ’71 are featured in a Washington Post piece highlighting “leading women in atmospheric and climate sciences who have forged the path to better our knowledge of the weather and world around us.” Solomon is an “internationally recognized as a leader in atmospheric sciences for her work in explaining the cause of the ‘hole in the ozone’ over Antarctica.”

Smoke from Australian wildfires in 2019 and 2020 appears to have contributed to the breakdown of the ozone layer, according to a new study by MIT scientists, reports Sharon Udasin for The Hill. “The new study establishes the first direct link between wildfire smoke and ozone depletion,” writes Udasin. 

Daily Beast reporter Miriam Fauzia writes that a new study by MIT scientists finds that smoke particles from wildfires are slowing the recovery of the ozone layer.
