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.”
A study by MIT researchers uncovers evidence that the Earth’s global ice ages were triggered by a rapid drop in sunlight, reports Mashable. The researchers found that an “event like volcanic eruptions or biologically induced cloud formation will be able to block out the sun and limit the solar radiation reaching the surface at a critical rate that can potentially trigger ‘Snowball Earth’ events.”
Forbes contributor Bruce Dominey writes that a study by MIT researchers finds global ice ages may have been triggered by a rapid decrease in the amount of solar radiation reaching Earth. “Past Snowball glaciations are more likely to have been triggered by changes in effective solar radiation than by changes in the carbon cycle,” writes Dominey.
A new study by MIT researchers examines the environmental impact of the Covid-19 pandemic, reports Steven Reinberg for HealthDay. "If the pandemic leads to a persistent global recession, there is a real threat to the adoption of clean technology, which could outweigh any 'silver lining' in environmental benefits," says Prof. Jing Li.
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.
John Yang reports for PBS NewsHour about technologies to harvest fog to secure the world’s water supply, including one system designed by Prof. Kripa Varanasi to collect water from power plant cooling towers. Varanasi and his team “discovered that zapping air rich in fog with a beam of electrically charged particles draws the droplets toward the mesh, dramatically increasing its ability to collect water,” says Yang.
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.
Profs. Daniel Rothman and Daniela Rus contributed to a Boston Globe piece exploring what the next big moonshot challenge should be. Rothman noted that, “We need to understand how the Earth system responds to environmental change,” while Rus expressed a desire to explore interspecies communication and the development of intelligent clothing.
A study by Prof. Dan Rothman finds that increasing greenhouse gas emission rates could trigger a mass extinction in the ocean, reports Priya Shukla for Forbes. Shukla writes that Rothman found if a certain carbon threshold “is breached, it would take tens of thousands of years for the oceans to return to their original unperturbable state.”
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.
MIT’s Solve initiative is accepting solutions for its Circular Economy Challenge, which focuses on renewable energy and waste elimination. “Ideas that help communities move towards zero waste and zero carbon through STEM education on new design and production techniques could win the GM Circular Economy Prize,” writes Natalie Parletta for Forbes.
A new study co-authored by MIT researchers finds that factories in China have been emitting a compound banned under the Montreal Protocol that destroys the Earth’s ozone layer, reports Yen Nee Lee for CNBC. The researchers found that “China accounted for 40% to 60% of the global increase in trichlorofluoromethane, or CFC-11, emissions between 2014 and 2017.”
