Kerry Emanuel on climate change and hurricanes

A satellite measurement of Hurricane Harvey on Aug. 25 found that intense storms in the eastern side were dropping rain at a rate greater than 3.2 inches (82 mm) per hour.

“‘[With global warming, we could see] a 50-percent increase in the destructive potential” of the most powerful tropical storms,’ says meteorologist Kerry Emanuel of the Massachusetts Institute of Technology.”

For decades, MIT’s Kerry Emanuel has been a go-to researcher for those seeking insight into how climate change may affect catastrophic storms. The above quote is from 1992, in a Newsweek article “Was Andrew a Freak — Or a Preview of Things to Come?” — and has never been more timely.

Kerry is also an eloquent and forceful voice pushing leaders around the world to take the risks of climate change more seriously.

Now we’re once again deep into storm season around the world, and it’s not pretty. With events still unfolding in Texas with Hurricane/Tropical Storm Harvey, and weeks of escalating devastating monsoon floods in Bangladesh, India and Nepal, many people are asking: are these extreme storms the result of climate change?

The current thinking: it’s complicated. Foremost, we shouldn’t be seeking a direct causal link between climate change and any particular storm. As Professor Emanuel told The Washington Post’s Chris Mooney a few days ago:

“My feeling is, when there’s a hurricane, there’s an occasion to talk about the subject,” he said. “But attributing a particular [weather] event to anything, whether it’s climate change or anything else, is a badly posed question, really.”

Scientists are clear that climate change has “threat multiplier” effects on storms, increasing the likelihood and severity of some aspects. For instance: warmer waters and warmer air increase the moisture available and the energy in storms; disruptions in atmospheric circulation increase the likelihood of a storm “stalling out” over a region; and ocean storm surges are made more destructive when melting ice caps have raised the baseline sea level.

“The thing that keeps forecasters up at night is the prospect that a storm will rapidly gain strength just before it hits land,” Emanuel recently told Agence France-Presse, citing Harvey as an example. “Global warming can accentuate that sudden acceleration in intensity.”

Interestingly, it’s still uncertain whether global warming will lead to more or less frequent hurricanes. But in terms of catastrophic damage, storm frequency seems less important than the severity of storms, where climate change does have a clear footprint.

[Update, Sept. 26 2017: Kerry just gave an in-depth 1 hour talk at MIT, entitled “What Do Hurricanes Harvey and Irma Portend?” Watch the video, or read highlights in the news coverage.]

Kerry Emanuel has been a frequent contributor on OCW. Check out these two courses particularly connected to the storms + climate change issue.

  • 12.103 Science and Policy of Natural Hazards introduces the science of natural catastrophes such as earthquakes and hurricanes and explores the relationships between the science of and policy toward such hazards. It presents the causes and effects of these phenomena, discusses their predictability, and examines how this knowledge influences policy making.
  • 12.340 Global Warming Science provides a scientifically rigorous foundation to understand anthropogenic (human-caused) climate change, an introduction to climate models, the material impacts of climate change, and the science behind mitigation and adaptation proposals. [See also the archived MITx on edX version of this course.]

One of our favorite things at MIT OpenCourseWare is to shine a spotlight on fascinating subjects and great teachers that might otherwise escape notice. We’ve written before on the strength of MIT’s School of Humanities, Arts and Social Sciences (SHASS), both in their own right and in community with MIT’s more widely recognized STEM and business programs. OCW is pleased to freely share material from nearly 800 courses from across all SHASS disciplines.

Where to begin among all this free learning material? If you’re an educator (or just curious about teaching and learning process), you’re in luck!  OCW Educator project manager Sarah Hansen recently worked with SHASS colleagues to compile a list of OCW highlights, which we republish here. Each of these links goes to the course’s “This Course at MIT” section, where the instructor shares detailed insights about their teaching approach.

William Bowen, Mellon Foundation president who led initial OCW funding, dies at 83

MIT OpenCourseWare joins with our colleagues across higher education to mourn the passing of William Bowen. As president of the Mellon Foundation, he played a central role in the creation of OpenCourseWare.

More on the OCW story below. But first, those who didn’t know Bowen can get a glimpse of his life and reach in Brian Rosenberg’s eloquent rememberance in The Chronicle of Higher Education:

To Bill Bowen, the important things always mattered, regardless of his age or his title. He cared in 2016 as passionately about the entrenched inequities in higher education as he did when he assumed the presidency of Princeton, at age 38. He cared as much about issues of academic freedom and free speech as he did in 1973, when he defended the right of William Shockley, a physics professor who believed blacks were genetically inferior, to say things that Bowen himself found deeply offensive. He argued as forcefully for the importance of the arts and humanities in our culture as he did when he assumed the presidency of the Andrew W. Mellon Foundation, in 1988.

He never stopped caring, and he never stopped being the most thoughtful and articulate voice on these and a host of other issues central to our educational system and our civic life…

Outside the circles of academe, his name is not nearly as well known as those of innumerable politicians and business people. But whether they know his name or not, many people who have attended a college whose doors would have been closed to them previously, or who received financial aid that created a world of new possibilities, are better off because Bill Bowen cared about their lives.

How did Bill Bowen come into the OCW fold? In 2000, MIT President Charles Vest had just received the revolutionary recommendation that would lead to OpenCourseWare. An Institute committee of faculty, staff and alumni felt that MIT should respond to the rapid growth of the Internet by giving all of its basic teaching materials away on the web for free.

President Vest quickly saw the wisdom and the enormous potential of the proposal, and set out to make it real. One of the first big questions: how to fund it? His first stop was none other than Bill Bowen. Vest describes their initial meeting:

I had breakfast in New York with Bill Bowen, the distinguished former president of Princeton University and current president of the Andrew W. Mellon Foundation. Bill is that rare combination, a deep thinker and an effective leader.

Over eggs, I said, “Bill, I want to tell you how MIT is thinking about using the Internet for education. Then I’ll have three questions. Do you think it’s a good idea? If you think it is a good idea, do you think foundations might fund it? And, if so, might The Mellon Foundation be interested?”

Normally when one approaches a foundation for support, the answer, if not “No,” is a request to send a letter. Then one might be asked to do a draft proposal with an approximate budget. Finally, one might be asked for a full-blown proposal, to which the ultimate response seems most likely to be rejection. In this case, Bill looked at me and said, “Don’t take this idea anywhere else. Let’s go to work to figure out how to fund it.”

Vest tells an expanded version of this story, with more recollections of Bill Bowen, in the following video from a 2011 panel discussion (clip starts at 13:20).

Teaching Calculus, the Beautiful Language of Change

 

Move…accelerate…reach the peak…bottom out…transform…

So many ways to look at change, to talk about change. Change is inescapable. And change can be scary, especially when you don’t understand what’s happening. Yet change can also be an opportunity for growth, for progress, for new insights.

The same could be said of the millions of students who take calculus classes every year. As teachers know, it’s a rich opportunity for student growth and insight, and also scary as they’re getting started. More than a math subject, calculus is fundamentally the language of change. It’s a beautiful and powerful expression of this universal phenomenon, and a great way to tackle a wide range of real-world problems.

MIT’s John Bush, professor of applied mathematics (and a fabulous photographer of fluid phenomena), offers some great calculus teaching tips in the above video. We hope you can motivate students by demonstrating how to revel in the beauty of the language, and all the things it can do, before diving into the nitty-gritty grammar of deltas and epsilons. Professor Bush suggests:

  • Sharks hunt with calculus! They intuitively “follow the gradient” of scent, or the direction that gives the highest rate of increase, to take them toward their prey.
  • Introductory physics students will have learned Snell’s law as an equation about the angles of light paths through different media. But calculus can show that it’s fundamentally an optimization problem of light following the fastest route; just like how a smartphone GPS map calculates your fastest route home through tangled streets and busy traffic. (See this explanation of route-finding by mathematician and writer Steven Strogatz.)
  • Archimedes’ Principle is a great way to experience the concept and importance of volume, and also the way integrals work. (Again, see Steven Strogatz’s engaging explanation.)

As Professor Bush says, calculus “is a language that’s valuable in virtually all disciplines, from physics to biology, from finance to engineering.”  Motivate deeper student engagement by demonstrating how beautiful it can be to describe their ever-changing world with the poetics of mathematics.

A Student-Centered Ethic

Person writing on a chalkboard at the front of a classroom,

A teaching assistant in one of the ‘mega-recitation videos’ for 6.034 Artificial Intelligence.

By Joe Pickett, OCW Publication Director

Like it or not, the first two years of an undergraduate’s education at a research university often consists of large lectures taught by professors, supplemented by discussion groups or problem-solving sessions (sometimes called “recitations”) run by teaching assistants (TAs).  Consequently, for many undergraduates, a TA is the first college instructor they get to know on a personal level.

So teaching assistants can have a huge impact on the experience of undergraduates, especially in the early going, where a student’s attitude about learning can take off—or stall out. Luckily, most TAs take their jobs seriously and put a lot of effort into helping their students.

Fostering Real Intelligence and Well-Being

OCW has for the first time provided a glimpse into the thinking that TAs put into their teaching by publishing the TAs’ Instructor Insights for 6.034 Artificial Intelligence. The TAs, Jessica Noss and Dylan Holmes, explain how they adhere to a student-centered ethic initiatied by Professor Patrick Winston, where the primary objects is “to help students learn the material and to become inspired.” This ethic informs all the course policies and TA activities, from assignment due dates to grading.

For instance, since the point of assessment is to demonstrate mastery (and not to make fine distinctions in accrued points), the final exam is optional, and four of its five parts reflect knowledge already assessed in quizzes given earlier in the semester. So if a student does poorly on a quiz, there’s a chance for redemption in the final. This relieves the pressure to do well on a single test.

Assignments are due by 10PM rather than the traditional zero hour of midnight to encourage students to get a decent night’s sleep.

Taking It Online

The TAs engage directly with students both in class and out. On an online forum, the TAs answer student questions, and these exchanges are visible for the entire class to see. Over time, the forum functions as an archive of Frequently Asked Questions and helps inform how recitations are taught.  But running an online forum can be tricky, and the TAs share how they have responded to the challenges to make the exchanges more productive.

Facing the Challenges

It’s not easy being a TA. You’re just starting out, just beginning to learn how to engage students and foster learning. You have to learn how to plan and manage a successful recitation, for example. Students can ask all kinds of questions that you might not know the answer to. And you have to do this while dealing with the pressures of being a student yourself.

For Noss and Holmes, the point is to show the students that the TAs care about them and about how well they do—that is, how well they learn. That’s an ethic that’s easy to get behind.
