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.
Researchers from MIT and other institutions have uncovered evidence that early dinosaurs may have lived in social herds, reports Kate Baggaley for Popular Science. “People have known for a long time that the more advanced dinosaurs, the ones that lived in the late Jurassic and Cretaceous, especially the large sauropods…moved and lived in herds,” explains research scientist Jahandar Ramezani. “But the question has always been, when did this behavior start?”
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.
CBS Boston spotlights how Prof. Taylor Perron has been honored with a 2021 MacArthur Fellowship for his work “unraveling the mechanisms that create landscapes on Earth and other planets.” CBS Boston notes that Perron is “currently studying river networks on Mars and one of Saturn’s moons for clues about the climate history of each celestial body.”

A team of researchers led by MIT visiting scientist Judah Cohen has found that climate change is amplifying winter weather disasters, including the rare cold snap in Texas and other southern states in February 2021, reports Becky Ferreira for Motherboard. “The team used both observational data and climate models to expose ‘stretching events’ in the polar vortex that cause its circular shape to become elongated across the Arctic,” writes Ferreira. “This phenomenon ‘is linked with extreme cold across parts of Asia and North America.’”
A new study co-authored by MIT researchers finds that climate change is likely causing more extreme winter weather, reports Hallie Golden for The Guardian. The researchers found that changes in the Arctic brought on by climate change “actually increased the chances of tightly spinning winds above the North Pole, known as the Arctic stratospheric polar vortex, being stretched and thus boosting the chances of extreme weather events in the US and beyond.”
New Scientist reporter Adam Vaughan writes that a new study led by visiting scientist Judah Cohen finds that climate change may be causing more extreme winter weather in North America and Eurasia. “If you expected global warming to help you out with preparing for severe winter weather, our paper says the cautionary tale is: don’t necessarily expect climate change to solve that problem for you,” says Cohen. “This is an unexpected impact from climate change that we didn’t appreciate 20 years ago.”
Prof. Kerry Emanuel discusses how climate change impacts the rapid intensification of storms like Hurricane Ida with Washington Post reporter Sarah Kaplan. “This is exactly the kind of thing we’re going to have to get used to as the planet warms," says Emanuel.
Vice reporter Becky Ferreira writes that a study by MIT scientists examining extreme climate events in the Earth’s history finds that as the planet warms we could be more susceptible to volatile climate extremes. “I think these results emphasize that Earth's long-term evolution is governed by complex, potentially amplifying mechanisms that we do not yet fully understand,” explains graduate student Constantin Arnscheidt.
Inside Science reporter Tom Metcalfe writes that MIT researchers have developed a new method for taking the Earth’s temperature by examining basaltic rocks, and used the method to create a model of the Earth's oceanic ridges. "We are constantly stressing how [plate] tectonics operated in the past," says postdoc Stephanie Brown Krein. "And so I think it's really important for us to be able to understand how tectonics are working in the present day.”
A new study co-authored by postdoctoral associate Michaël Marsset details how two red objects that have been discovered in the asteroid belt between Mars and Jupiter appear to have originated beyond Neptune, reports Jonathan O’Callaghan for The New York Times. “In order to have these organics, you need to initially have a lot of ice at the surface,” explains Marsset. “So they must have formed in a very cold environment.”
A new study by MIT researchers finds that the oceans may begin emitting chlorofluorocarbons by 2075, reports Valerie Yurk for E&E News. “Even if there were no climate change, as CFCs decay in the atmosphere, eventually the ocean has too much relative to the atmosphere, and it will come back out," says Prof. Susan Solomon.
CNN reporter Ivana Kottasová writes that a new study co-authored by MIT researchers finds there has been a significant drop in CFC emissions and a resumption in the recovery of the ozone layer. Prof. Ronald Prinn, director of the Center for Global Change Science at MIT, said that the results were “tremendously encouraging,” adding that “global monitoring networks really caught this spike in time, and subsequent actions have lowered emissions before they became a real threat to recovery of the ozone layer.”
The Climate Modeling Alliance (CliMA), which includes a number of MIT researchers, is working on developing a new climate model that could be used to create more accurate climate predications that could be useful at the local or regional levels, reports Doug Struck for The Christian Science Monitor. “It’s always a mistake to say that you shouldn’t try something new,” says Prof. Raffaele Ferrari. “Because that’s how you change the world.”
