Prof. Benjamin Weiss speaks with Forbes contributor Bruce Dorminey about his latest co-authored paper detailing new paleomagnetic measurements of samples of Antarctic meteorites. “Our study shows that the solar nebula – the cloud of gas and dust out of which our solar system formed, dissipated very quickly (within less than 1.5 million years) after having lasted for 3 million years,” Weiss tells Dorminey.
Associate Group Leader at the Lincoln Laboratory, William (Bill) Blackwell is the principal investigator for NASA’s TROPICS mission, which is preparing to launch small satellites into space to help better track the development of tropical storms, reports Justine Calma for The Verge. “With more frequent observations from these satellites, scientists hope to better understand how tropical storms grow and intensify,” writes Calma.
A new study co-authored by MIT researchers finds that global climate change is progressing faster than anticipated, reports Xinhua News. “By comparing climate model simulations with current storm observations, the team discovered that human-caused storm intensification over recent decades has already reached the levels projected to occur in 2080.”
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.
Prof. Susan Solomon speaks with Wall Street Journal reporter Nidhi Subbaraman about her research and another recent study that provides evidence wildfire smoke poses a threat to the ozone layer. “It’s fair to say that, at least for a few months, these wildfires canceled out the last decade of all the efforts that we put in over the Montreal Protocol,” says Solomon. “I think there’s every reason to believe this is going to happen more often, and it’s going to act to slow down the recovery of the ozone depletion.”
Forbes contributor David Bressan writes that a new study by MIT researchers proposes that oxygen began accumulating in early Earth’s atmosphere due to interactions between marine microbes and minerals in ocean sediments. The researchers hypothesize that “these interactions helped prevent oxygen from being consumed, setting off a self-amplifying process where more and more oxygen was made available to accumulate in the atmosphere,” writes Bressan.
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.
BBC News correspondent Helen Briggs writes that MIT scientists have found that increasing wildfires may slow the recovery of the ozone layer. "All the hard work that the world went to to reduce chlorofluorocarbons (ozone-depleting chemicals once used in aerosol sprays) is not paying off as well in the areas that experience extreme wildfires," explains Prof. Susan Solomon. "The best hope would be that we reduce global warming gases also and stop increasing the wildfires, but that's obviously more difficult."
A new study by MIT scientists finds that smoke emitted into the atmosphere from Australian wildfires in 2019 and 2020 resulted in depletion of the ozone layer, reports Donna Lu for The Guardian. The findings suggest “rising fire intensity and frequency due to the climate crisis may slow the recovery of the ozone layer.”
Prof. Sara Seager speaks with Tom Metcalfe of NBC News about the Venus Life Finder missions, which will carry a robotic space payload partially funded by MIT alumni to Venus to search for signs of life in the planet's atmosphere. “Space is becoming cheaper in general, and there is more access to space than ever before,” says Seager.
Researchers from MIT and Princeton University have found that flooding events will become much more common by the end of the century, especially in New England, reports Evan Bush for NBC. “The researchers used computer modeling to stimulate thousands of ‘synthetic’ hurricanes toward the end of this century and in a scenario where greenhouse gas emissions are very high,” writes Bush.
Researchers from MIT, Tripura University, and Vaisala Inc. concluded that the decline of aerosols in the atmosphere led to a reduction in lightning activity during the Covid-19 lockdown period, reports Alaa Elassar for CNN. “As countries around the world imposed quarantines, lockdown and curfews aimed at limiting the spread of Covid-19, air pollution levels fell drastically, thereby reducing the amount of aerosols released into the air,” writes Elassar.
Inside Science reporter Will Sullivan writes that a new study co-authored by MIT researchers finds that during Covid-19 lockdowns in the spring of 2020 there was a reduction in human activities that release aerosols into the atmosphere, resulting in diminished lightning activity.
