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.”
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.
Politico reporter Alex Daugherty spotlights a study from MIT and the International Council on Clean Transportation which found “that the use of alternative jet fuels like e-kerosene in supersonic transport aircraft would still lead to an increased worsening of climate change because these faster gets burn more fuel per passenger.”
The Haystack Observatory will be hosting a virtual climate change forum on Jan. 27, featuring Haystack’s director Colin Lonsdale and research scientist Pedro Elosegui, reports John Laidler for The Boston Globe. “Lonsdale will provide general information about the work of Haystack and climate science,” writes Laidler. “Elosegui will discuss Haystack’s polar research, which includes studies of global climate and sea-level change.”
The Conversation reporter Stacy Morford spotlights research by climatologist Judah Cohen and atmospheric scientist Mathew Barlow, which shows how changes in the Arctic can lead to changes in the stratospheric polar vortex, and cold waves in North America and Asia. “Our research reinforces two crucial lessons of climate change: First, the change doesn’t have to occur in your backyard to have a big effect on you,” write Cohen and Barlow. “Second, the unexpected consequences can be quite severe.”
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.
A study by MIT and the National League of Cities has attempted to identify the qualities of a “climate destination” where the effects of climate change are expected to be easier to manage, reports Kate Yoder for Wired. “With as many as 143 million people worldwide expected to be on the move because of climate change by 2050, would-be havens are sure to face new challenges,” writes Yoder. “But advance planning can alleviate the stress on cities as well as on their newcomers.”
Reuters reporter Andrea Januta writes that using computer models Prof. Kerry Emanuel has found that hurricanes in the North Atlantic have been growing in intensity and frequency as global temperatures have increasing. Emanuel “turned to computer simulations to recreate climate conditions for the last 150 years. Using three different climate models, he then scattered hurricane “seeds,” or conditions that could produce a storm, throughout the models to see how many seeds developed into storms,” writes Januta.
A new study by Prof. Kerry Emanuel examining the history of hurricanes finds that North Atlantic hurricanes are increasing in frequency and intensity, write Matthew Cappucci and Jason Samenow for The Washington Post. Emanuel “employed a novel approach to evaluate past storm activity,” they write. “Rather than relying on historical observations, which may have gaps, he performed climate modeling to reconstruct a continuous record of hurricane activity over the past 150 years from which to gauge trends.”
Writing for The Guardian, Prof. Daniel Rothman examines the history of Earth’s mass extinctions and how Earth seems to experience “a cascade of disruptions when stressed beyond a tipping point." Rothman writes that: “If we do not significantly cut back CO2 emissions, then we risk passing the threshold before the end of the present century.” He adds, “let us not contribute to the risk of a sixth extinction. Efforts to limit CO2 emissions now may pay dividends further into the future than we can imagine.”
Prof. Taylor Perron, a recipient of one of this year’s MacArthur fellowships, speaks with Callie Crossley of GBH’s Under the Radar about his work studying the mechanisms that shape landscapes on Earth and other planets. “We try to figure out how we can look at landscapes and read them, and try to figure out what happened in the past and also anticipate what might happen in the future,” says Perron of his work as a geomorphologist.
Forbes contributor Michael T. Nietzel spotlights the work of Prof. Taylor Perron, who was awarded a 2021 MacArthur Fellowship. “By using mathematical modeling, computer simulations, and field studies, Perron is able to describe the environmental history of current landscapes and predict how landscapes will respond to future environmental changes," writes Nietzel.
