Pollution

Hanna Ali of NOVA Next speaks with Prof. Desiree Plata about methane emissions and Prof. Tim Swager about his work developing sensors that could allow users to “see” methane, track down its source and mitigate impacts. “You probably hear headlines all the time, ‘Everywhere we look for plastics in the environment, we find them,’” Plata says. “The same is true of most industrial chemicals, but the problem is I can’t pull out my cell phone and take a picture of [them]. Tim’s sensors are helping to close that gap.”

Senior Research Scientist Stephanie Seneff co-authored an opinion piece for The Washington Post, which examines how the high level of herbicide chemicals found in Florida waterways is contributing to a record number of manatee deaths. “If we want to stop manatees from starving, we have to stop using this harmful chemical on our crops, on our lawns and in our waterways,” they conclude. 

A new study by MIT researchers finds that the oceans may begin emitting chlorofluorocarbons by 2075, reports Valerie Yurk for E&E News. “Even if there were no climate change, as CFCs decay in the atmosphere, eventually the ocean has too much relative to the atmosphere, and it will come back out," says Prof. Susan Solomon.

CNN reporter Ivana Kottasová writes that a new study co-authored by MIT researchers finds there has been a significant drop in CFC emissions and a resumption in the recovery of the ozone layer. Prof. Ronald Prinn, director of the Center for Global Change Science at MIT, said that the results were “tremendously encouraging,” adding that “global monitoring networks really caught this spike in time, and subsequent actions have lowered emissions before they became a real threat to recovery of the ozone layer.”

Prof. Jessika Trancik speaks with Jesse Remedios of WBUR about her new study that identifies locations where electric vehicle charging stations would have the most impact and help increase the adoption of electric vehicles. “It's important to make sure that chargers are placed where people can charge without having to delay their activities,” Trancik says. 

New York Times reporter Brad Plumer spotlights a new study by Prof. Jessika Trancik that finds “new chargers on residential streets, as well as high-speed charging stations along highways, would go a long way to supporting an electric-vehicle boom.” 

Mashable reporter Sasha Lekach spotlights a new study by MIT researchers that finds installing more charging stations close to residences and in locations that match where people naturally stop, would help increase usage of electric vehicles. The researchers found that “this helps to make charging more accessible while drivers are going about everyday activities.”

Institute Professor Emeritus Mario Molina, who former Vice President Al Gore called a “trailblazing pioneer of the climate movement,” has died at age 77, reports John Schwartz for The New York Times. Molina shared a “Nobel Prize for work showing the damage that chemicals used in hair spray and refrigerators wreak on the ozone layer, which led to one of the most successful international efforts to combat environmental risk.”

Guardian reporter Fiona Harvey memorializes the life and work of Institute Professor Emeritus Mario Molina, known for his research uncovering the impact of CFCs on the ozone layer. Harvey notes that Molina’s work, “will also help to avert ruin from that other dire emergency, the climate crisis.”

Institute Professor Emeritus Mario Molina, known for his work demonstrating the risk of CFCs to the ozone layer, has died at age 77, reports Emily Langer for The Washington Post. Langer notes that Molina was also “a prominent voice in debates about how best to combat climate change.” 

Fast Company reporter Kristin Toussaint writes that a study by MIT researchers finds shutdowns and lockdowns caused by the coronavirus pandemic led to clearer skies and increased solar output in Delhi. “I think we’ve been able to get a glimpse of how the world can look like if we actually have clean air,” says research scientist Ian Marius Peters.

Verge reporter Justine Calma writes that states in the Midwest and Great Lakes region could see $4.7 billion in health benefits by maintaining current renewable energy standards. “This research shows that renewables pay for themselves through health benefits alone,” explains Emil Dimanchev, senior research associate at MIT’s Center for Energy and Environmental Policy Research.

A new study by MIT researchers examining the impact of energy policies that reduce fine particulates in the air finds that there are “substantial health benefits in Rust Belt states when utilities are required to supply escalating amounts of renewable power,” reports Ben Geman for Axios.

A new MIT study shows that “China’s move away from fossil fuels would mean 2,000 fewer premature deaths in the U.S. by 2030,” reports John Fialka for E&E News. "It reminds us that air pollution doesn't stop at national boundaries," said Prof. Valerie Karplus, a co-leader of the paper. 

The BBC series “Follow the Food” spotlights how MIT researchers are tackling the issue of runoff pesticide pollution by developing a technology that helps pesticide better adhere to plant leaves. “What we are trying to do is come up with a technology that can help farmers and significantly reduce the amount [of pesticide] sprayed,” explains Prof. Kripa Varanasi.
