Study: Smoke particles from wildfires can erode the ozone layer
MIT chemists show the Australian wildfires widened the ozone hole by 10 percent in 2020.
Methane research takes on new urgency at MIT
Desiree Plata's research focuses on developing technologies and strategies for environmental sustainability.
Study reveals chemical link between wildfire smoke and ozone depletion
If wildfires become larger and more frequent, they might stall ozone recovery for years.
Understanding air pollution from space
Arlene Fiore uses satellite data paired with ground observations to refine our understanding of ozone smog and interactions with meteorology and climate.
Arlene Fiore appointed first Stone Professor in Earth, Atmospheric and Planetary Sciences
Fiore brings a breadth of expertise in climate science, atmospheric chemistry, and air pollution to MIT.
New approach could change how we track extreme air pollution events
Study demonstrates the power of low-cost air quality sensors during volcanic eruption.
Ozone-depleting chemicals may spend less time in the atmosphere than previously thought
New results point to unexpected, illegal production of several CFCs in recent years.
Study predicts the oceans will start emitting ozone-depleting CFCs
As atmospheric concentrations of CFC-11 drop, the global ocean should become a source of the chemical by the middle of next century.
Reductions in CFC-11 emissions put ozone recovery back on track
Scientists observe reduction in emissions of banned ozone-depleting chemical after unexpected spike.
Institute Professor Emeritus Mario Molina, environmental leader and Nobel laureate, dies at 77
The atmospheric chemist shared the Nobel Prize for the discovery that chemicals known as CFCs deplete the ozone layer.
Susan Solomon earns Killian Award, MIT’s highest faculty honor
Atmospheric chemist is recognized for her “leadership in working toward real-world solutions to address the global climate crisis.”
Emissions of several ozone-depleting chemicals are larger than expected
Recovering and safely destroying the sources of these chemicals could speed ozone recovery and reduce climate change.
Tracking emissions in China
Evaluating a 2014 policy change yields some good news and some concerns.
Scientists discover the source of new CFC emissions
Despite global phase-out, the ozone-depleting chemical is still in production in eastern China.
New threat to ozone recovery
Study finds chloroform emissions, on the rise in East Asia, could delay ozone recovery by up to eight years.
