MIT researchers are working to uncover new ways to avoid contrails and minimize their impact on global warming, reports Nicolas Rivero for The Washington Post. “Whether [the contrail impact is] exactly 20 percent or 30 percent or 50 percent, I don’t think anybody knows that answer, really,” says research scientist Florian Allroggen “But it also doesn’t really matter. It’s a big contributor and we need to worry about it.”
David Zipper, a senior fellow at the MIT Mobility Initiative, writes for Slate about the “continually expanding size of the typical American automobile” and the deadly consequences of car bloat. “In 1977, SUVs and trucks together represented 23 percent of American new car sales; today they comprise more than 80 percent,” writes Zipper. “Meanwhile, the models themselves keep getting larger. These four-wheeled behemoths started as niche vehicles, meant to allow certain groups of people to accomplish specific tasks. Today they have become a fixture of everyday American life. They are also linked to myriad societal ills, from crash deaths to climate change to social inequality. Bigger cars make each of those problems harder to solve.”
Michael Mehling, deputy director of the Center for Energy and Environment Policy Research, speaks with E&E News reporter Benjamin Storrow about the impact of global climate deals on climate change. “The history of the Paris Agreement suggests that global climate deals do make a dent in emissions,” Mehling says. “But the impact can be subtle and felt over time.”
MIT students have created a “countdown clock” to help conceptualize how close the globe is to reaching a concerning level of warming, reports Paula Moura for WBUR. “There’s only 60 Bruins games, six Patriots games and 30 Red Sox games scheduled — or about six months — until scientists estimate the globe reaches a point of no return for extreme weather and species loss,” writes Moura. “Everyone is really alarmed because even college students at a very technical university have trouble conceptualizing how soon this is,” says second-year student Norah Miller. “Even though a lot of us are not Boston natives, these kinds of statistics in terms of sports really hit home.”
Writing for The Hill Prof. Emeritus Henry Jacoby highlights the importance of addressing climate change in discussions of government policy. “If the global emission reduction efforts falter, the ensuing damages to the most vulnerable will be especially dire,” says Jacoby. “The world is already plagued with failed nation-states unable to sustain their population while maintaining political stability. As the number of these nation-state failures increases, there will be hundreds of millions of environmental refugees and stateless people, taxing the available resources of the entire planet.”
Boston Globe reporter Vivi Smilgius spotlights the MIT Climate Clock, a massive clock being projected onto MIT’s Green Building that uses Celtics, Patriots and other local sports teams as a means to count down to the projected date and time that the planet is expected to have warmed by 1.5 degrees Celsius over preindustrial levels. “Someone might get that there are six Pats games until this event. That makes a lot more sense to people,” said second-year student Norah Miller. “It’s a sense of personal urgency.”
Writing for The Hill, Prof. Emeritus Henry Jacoby, former co-director of the MIT Joint Program on the Science and Policy of Global Change, and his colleagues make the case for a concerted scientific effort to better understand the risks posed by exceeding climate tipping points. “These risks are becoming more serious with every tenth of a degree of global warming,” they write. “Investment in a better understanding of tipping point risks might be the best investment humanity could now make in the effort to preserve a livable planet.”
Prof. Yet-Ming Chiang has been named to the TIME 100 Climate list, which highlights the world’s most influential climate leaders in business. “When it comes to cleantech, if it won’t scale, it doesn’t matter,” Chiang says. “This is a team sport—companies large and small, and governments state and federal, need to work together to get these new technologies out there where they can have impact.”
Prof. Jacopo Buongiorno speaks with Danny Lewis, host of The Wall Street Journal’s “Future of Everything” podcast, about the future of nuclear power plants. “As countries, regions, businesses contemplate their future plans for reducing carbon emissions, nuclear is one technology that they have got to consider,” says Buongiorno. “It's an incredibly dense energy source, so you don't need a big supply chain that continuously feeds the power plant with fuel, the same way that you would with coal, for example. Also, the machine itself, the reactor is very, very compact.”
Principal Research Scientist Emre Gençer speaks with The Independent reporter Louise Boyle about natural hydrogen and its potential as a future renewable energy source. “There is a ‘mismatch’ where natural hydrogen is being discovered and where it could be used, which would require massive investments in completely new infrastructure,” says Gençer. “I think it will be part of the solution but we need to take it with a grain of salt.”
Postdoctoral associate Milan Klöwer shares how large conferences can impact air travel and personal carbon footprints, reports Sydney Johnson for KQED. “Flying is one of the sectors where there are enormous inequalities,” says Klöwer. “The people that earn the most [money] fly the most, and therefore have personal carbon footprints that are thousands of times larger than the poorest people on the planet. There is a responsibility for people to understand that problem about how they are personally emitting.”
A study co-authored by research scientist Evan Fricke found that “extinctions and declines in habitat [of migratory birds] have dramatically reduced the long-distance dispersal of seeds,” reports Liam Drew for The Atlantic. “There have been really strong declines in long-distance seed dispersal as a result of the massive loss of big animals from the ecosystems,” says Fricke.
Prof. Kerry Emanuel speaks with Living on Earth host Jenni Doering about the future of extreme weather forecasting. “We have to do a much better job projecting long term risk, and how that's changing as the climate changes so that people can make intelligent decisions about where they're going to live, what they're going to build, and so on,” says Emanuel. “We need better models, we need better computers, so that we can resolve the atmosphere better, we need to make better measurements of the ocean below the surface, that's really tough to do.”
Cipher News editor Amy Harder spotlights the MIT Renewable Energy Clinic, a new course developed by Prof. Larry Susskind aimed at training students to be mediators in conflicts over clean energy projects. Harder notes that the course is focused on creating “collaboration that may slow down projects initially by incorporating more input but ultimately speed them up by avoiding later-stage conflicts.”
