Forbes reporter Jeff McMahon spotlights visiting scientist Judah Cohen for his research examining the connection between Arctic snow cover and sea ice to cold air intrusions in the United States during the month of February. “December has certainly been warming if you look at the U.S.,” sayscCohen. But “February, going back to 1979—so quite a few years now—we're actually seeing in the center of the U.S. a very distinctive cooling trend.”
Prof. Zachary Cordero and his team are working to develop an in-space manufacturing technique to design a satellite reflector that can monitor storms and precipitation through moisture changes in the atmosphere, reports Ramin Skibba for Wired. “It involves bending a single strand of wire at specific nodes and angles, then adding joints to make a stiff structure,” writes Skibba.
MIT researchers have found that in the U.S., “fires started by people account for a majority of premature deaths related to inhalation of tiny smoke particles,” writes Cara Murez for U.S. News & World Report. “Fires not only threaten human lives, infrastructure and ecosystems, but they are also a major cause for concern in terms of air quality,” says Therese Carter PhD ’22.
Research Scientist Mary Knapp’s proposal for a Great Observatory for Long Wavelengths (GO-LoW), a space-based observatory consisting of thousands of satellites that could study the magnetic fields of distant and rocky exoplanets, has been selected for NASA’s Innovative Advanced Concepts programs, writes George Dvorsky for Gizmodo.
The Verge reporter Justine Calma writes that a new study by MIT researchers finds that while wind energy has measurably improved air quality, only 32% of those benefits reached low-income communities. “The research shows that to squeeze out the greatest health benefits, wind farms need to intentionally replace coal and gas power plants,” writes Calma. “And to clean up the most polluted places — particularly those with more residents of color and low-income households — those communities need to be in focus when deploying new renewable energy projects.”
A new study by MIT researchers finds that increased usage of wind power is improving air quality in parts of the U.S., however only a third of the health benefits are being seen in disadvantaged communities, reports Alan Mozes for HealthDay. "Going forward," explains Prof. Noelle Selin, "more targeted policies are needed to reduce the disparities at the same time, for example by directly targeting [fossil fuel] sources that influence certain marginalized communities."
Increased usage of wind energy has led to health benefits, but does not affect all communities equally, reports Saul Elbein for The Hill. The researchers found that in order to increase the benefits of wind energy, “the electricity industry would have to spin down the most polluting plants at times of high wind-supply — rather than their most expensive ones,” writes Elbein.
A new study by MIT scientists finds that Earth can self-regulate its temperature thanks to a stabilizing feedback mechanism that works over hundreds of thousands of years, reports Troy Farah for Salon. “The finding has big implications for our understanding of the past, but also how global heating is shaping the future of our home world,” writes Farah. “It even helps us better understand the evolution of planetary temperatures that can make the search for alien-inhabited exoplanets more fruitful.”
Researchers from MIT and elsewhere have found that brown carbon – released from burning biomass – could have a larger impact on the Earth’s climate than originally thought, write University of British Columbia student Nealan Gerrebos and University of British Columbia Prof. Alan Bertram for The Conversation. “The results show a warming effect on the climate from brown carbon that is twice that of the previous estimate,” write Gerrebos and Bertram.
Prof. Susan Solomon speaks with Associated Press reporter Seth Borenstein about the Antarctic ozone hole. “’Ozone depletion starts LATER and takes LONGER to get to the maximum hole and the holes are typically shallower’ in September, which is the key month to look at ozone recovery, not October,” says Solomon.
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.”
