Visiting Scientist Judah Cohen speaks with USA Today reporter Doyle Rice about how the polar vortex could send a blast over cold air to areas of the central and eastern United States. “I believe that the entire cycle of a weak or disrupted polar vortex that began at the end of November is coming to its conclusion by the end of next week,” explains Cohen. “Clearly, the polar vortex is strengthening and some period of milder weather in the central and eastern U.S. looks inevitable to me.”  

In an opinion piece appearing in Wired, Prof. Elfatih Eltahir and postdoctoral researcher Yeon-Woo Choi examine the “ongoing water scarcity crisis” in Tehran. “With dry soils and high evaporation, rivers and wetlands shrank. Falling reservoir levels led to disruptions in hydropower generation, and water shortages prompted strict saving measures across parts of the capital,” they write. “These cascading impacts exposed how vulnerable Tehran’s infrastructure, economy, and communities have become under compounding heat and drought stress.” 

Visiting Scientist Judah Cohen shares his thoughts on how the polar vortex will impact weather across the U.S. this December, reports Doyle Rice for USA Today. "My thinking is that the cold the first week of December is the appetizer and the main course will be in mid-December," Cohen explains. 

CNN spotlights how MIT researchers have developed a new ultrasonic device that can extract clean drinking water from moisture in the atmosphere. “This method is much faster, we’re talking minutes instead of hours, compared to the old way,“ CNN explains. The new device “could be a game-changer in desert conditions, and for communities around the world that don’t have reliable access to drinking water.” 

Researchers at MIT have developed a new “system that uses a vibrating ceramic ring to produce clean drinking water from humid air in several minutes,” reports Matthew Burgos for DesignBoom. Burgos explains that with the system developed by MIT researchers, "clean water-making can take a few minutes versus the tens of minutes or hours required by thermal designs. In their system, the engineers use ultrasonic waves to shake the water out of the material that can absorb moisture from the air.” 

The MIT Sailing Pavilion will house the floating wetland - a pilot project aimed at finding ways to improve Charles River water quality and restore biodiversity - l for the winter season, reports Brianna Borghi for NBC Boston. “The Charles River Conservancy installed the 730-square-foot floating wetland in 2020 following years of research and development,” Borghi explains. “Under the surface, the floating wetland serves as a feeding ground for zooplankton, which help keep toxic algae blooms under control.” 

Prof. Emeritus Kerry Emanuel speaks with Washington Post reporters Ben Noll and Ruby Mellen about the 2025 hurricane season. “The thing that really powers the hurricane is how fast you can transfer heat from the ocean to the atmosphere. The bigger the temperature difference, the faster you can transfer heat. The faster you can transfer heat, the more powerful the hurricane can be,” says Emanuel. “This past summer, the sea surface temperatures across much of the tropical Atlantic were warmer than normal, which is part of what led people to predict that there would be a very busy season.” 

Visiting scientist Judah Cohen speaks with Gizmodo reporter Ellyn Lapointe about how sudden stratospheric warming (SSW) could bring wintry temperatures to parts of the northern hemisphere next week. According to Cohen “this explains why forecasters expect western states to bear the brunt of next week’s cold temperatures, but that could still change,” writes Lapointe. 

Visiting Scientist Judah Cohen speaks with Newsweek reporter Amanda Greenwood about how a disruption of the polar vortex can impact the 2025-2026 winter outlook. “A sudden stratospheric warming [is] the largest type of disruption that occurs to the polar vortex,” says Cohen. “It is named because of the dramatic warming that occurs in the polar stratosphere (warming near the North Pole can exceed 100 degrees in just a few days). The warming displaces the polar vortex much further south than normal.”

Visiting scientist Judah Cohen speaks with USA Today reporters Doyle Rice and Janet Loehrke about how the polar vortex and La Niña could impact winter weather across the country. Overall, Cohen believes that "the behavior of the polar vortex is more influential in determining if the U.S. will experience cold weather."

New York Times reporter Annabel Keenan highlights the “Remembering the Future” exhibit at the MIT Museum, a sculptural installation created by Janet Echelman that uses “climate data from the last ice age to the present, as well as projected future environments, to create a geometric design.” Echelman worked with MIT faculty, including Prof. Raffaele Ferrari and Prof. Caitlin Mueller, to bring the project to life. Mueller explains that she developed a “high-fidelity digital twin of the sculpture generated through our computational simulation that you can orbit and pan through to get perspectives that you can’t see physically in the space.” 

Prof. Peter Shor speaks with Katia Moskvitch and her nine-year-old son Kai of The Quantum Kid about how quantum technologies could be applied to developing climate change and sustainability solutions. Shor explains that quantum computers can be used for “simulating quantum mechanics, which would really help immensely in designing new materials, and new materials could be very useful for solving the climate crisis.” 

New York Times reporter Catherine Porter spotlights Roofscapes, an MIT startup founded by Olivier Faber MArch '23, Tim Cousin MArch '23 and Eytan Levi MArch/MSRED '21 that aims to transform the zinc-roofed buildings in Paris into accessible green spaces as part of an effort to decrease building temperatures while improving quality of life. “We have an opportunity with all these untouched surfaces to do something that is virtually impossible anywhere else in a city like Paris,” explains Levi. “There’s a new way you can live.”

Prof. Catherine Wolfram speaks with Financial Times reporter Simon Mundy about the EU’s decision to begin applying the carbon border adjustment mechanism (CBAM) next year. “I’m not sure the Europeans quite realize just how powerful the CBAM was as an incentive for other countries to adopt carbon pricing,” says Wolfram. “It’s really started a global conversation.” 

Writing for the Financial Times, Prof. Carlo Ratti makes the case that “in a hotter world, trees should be considered more than decoration. This ancient infrastructure can cool not just our buildings but the cities themselves. And with AI, we can now plant better, with precision urban forestry. In a warming world, the smartest climate tech may be rooted in the ground — and it doesn’t strain the power grid.”
