A study from MIT and the University of California San Diego highlighted how temperature variation can affect sleep, reports Veronika Samborska and Chris Campbell for the Financial Times. “That survey of 765,000 US respondents reported that increased night temperatures were linked to a higher number of nights of “insufficient sleep” in the self-reporting by participants,” write Samborska and Campbell.
Alumna Jennifer Rumsey SM ’98 will become the first woman to lead Cummins, the largest maker of diesel engines for trucks and heavy-duty vehicles, since its founding in 1919, reports Alan Ohnsman for Forbes. “Rumsey… intends to continue the shift to products that generate far less climate-warming emissions,” writes Ohnsman.
Researchers at MIT have found that due to the ongoing circulation of dust, sea salt, and organic matter produced by vegetation, even eliminating all human-caused pollution would still leave half of the world’s population exposed to particulate levels deemed unsafe by the World Health Organization, writes David Wallace-Wells for The New York Times. “When pollution combines with extreme heat, researchers have found, overall mortality risk can grow by more than 20 percent.”
Research affiliate Jason Prapas founded Fyto, a company dedicated to developing hardware and software to automate and scale the production of aquatic plants, reports Christine Hall for TechCrunch. Prapas says that “Fyto’s technology taps into a farm’s waste streams as inputs to enable farmers to increase productivity and improve nutrient management while reducing production costs, water usage and greenhouse gas emissions, in some operations by over 50%.”
MIT scientists have suggested that a raft of thin-film silicon bubbles could potentially block the sun’s radiation from further warming the Earth and help prevent some of the impacts of climate change, reports Tim Newcomb for Popular Mechanics. “The MIT group believes that if the raft of bubbles can deflect 1.8 percent of incident solar radiation before it hits Earth, they can fully reverse today’s global warming,” writes Newcomb.
Researchers from MIT, University College London, the University of Cambridge, and the NOAA have found that space projects by Elon Musk, Richard Branson, and Jeff Bezos are contributing to global warming and depleting the earth’s protective ozone layer, reports David Vetter for Forbes. “The London-Cambridge-MIT team looked at all the rocket launches and reentries that took place in 2019 and found that the global warming efficiency of black carbon soot released from rockets is 500 times greater than the same substance released at the Earth’s surface and by aircraft,” writes Vetter.
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.”
A team of MIT researchers have proposed that rafts of bubbles, carefully positioned between the Earth and Sun, can deflect sunlight to prevent further global warming, reports Angely Mercado for Gizmodo.
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.
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.”
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.”
