On two nights in April, scientists and a legal scholar, who call Nyack home, will give presentations that demonstrate how urgent the hour is for our planet, and what we can do as individuals and a community to respond.

Robin Bell is the connective tissue between the two programs. On Tuesday April 2 at 6:30p at the Nyack Center, Bell, a Professor and Polar Researcher at the world-renowned Lamont-Doherty Earth Observatory and the President of the American Geophysical Union will moderate a panel on the precise threat to our planet caused by climate change that features her colleagues at Lamont, Nicole Davi, Adjunct Associate Research Scientist, Paleoclimatology, and tree-ring expert and William D’Andrea, Lamont Associate Research Professor of biology and paleo environment, expert on natural and human-induced climate change.
On Tuesday, April 16th, she will introduce her husband, Pace Law School Professor and director of Pace Environmental Litigation Clinic Karl S. Coplan. Coplan, who is also a principal outside counsel for Riverkeeper, Inc. Coplan will offer readings from his book Live Sustainably Now: A Low-Carbon Vision of the Good Life, offering practical advice on how to reduce your carbon footprint, including everything from how you eat, commute, and run your house, to life enriching travel and recreation.

The programs are sponsored by the host, the Nyack Center, along with Lamont-Doherty Earth Observatory of Columbia University’s Earth Institute, NyackNewsAndViews and La Taylaye Catering and Event Design.
I am honored to be one of the organizers. Tickets for each program at $20 ($35 for both) and include a catered receptions after each event.

Like millions of Americans, West Nyack’s Robin Bell dreads her commute. It’s not the time it takes to cover the 26,000 mile round trip. And while she certainly misses her family during the weeks she spends at her remote workspace; that is not the worst part. It’s the carbon footprint from the passenger and ski-equipped cargo planes that troubles her the most. Robin Bell is a climate scientist and air travel is the only practical way for her to get to her “office” at Field Camp Twin Otter in Antarctica.

Her interests range from ice sheet dynamics to sub-glacial ecosystems. Bell studies the mechanisms of ice sheet collapse and the environments beneath the Antarctic ice sheet, including the Gamburtsev Mountains. The Gamburtsev range, also known as the ghost mountains, are as large as the Alps with a summit that never sees the sun, buried beneath 2,000 feet of snow and ice.
“I use physics to paint pictures of the world,“ Bell said in a 2011 interview.  “I’ve been incredibly lucky in terms of being able to leverage physics to see through to these places that are pretty much hidden to the human eye.”
Bell uses geophysics to observe “how the ice sheets work, how they grow, how they change and how they are changing now.” The model for how ice sheets behave was, until recently, as simple as “putting an ice cube on a table and letting it melt.'”  Bell and her multinational scientific partners in Antarctica are observing a much more dramatic process. “Parts of the ice sheet…are like giant conveyor belts that move a lot of ice into the ocean fast. Conveyor belts that are as wide as the state of Rhode Island. “

As remote as her polar offices might be from our northern hemisphere Atlantic coastal setting, we are connected by the world’s oceans to the changes in the ecology of Antarctica and Greenland. In Antarctica, Bell is recording “how ice gets taken from the middle of ice sheets down along these fast flowing ice streams down into the ocean where they turn into icebergs and are the mechanism that raises global sea levels.”
“Since my grandmother was born, sea levels have risen one foot.” Bell said. “In the worst case scenario, the oceans could rise another foot in the next three decades, which means adapting to what we had seen since my grandmother was born a little quicker.”

Bell takes to the seas as a sailor as well as a scientist. “We sail as a family to soak in the open sea and sky and see new places together. I take a microscope and a small plankton net to look at the creatures in the sea, but that is just for fun.”
One of Bell’s recent projects included testing a new imaging system “icepod” that is designed to  measure ice thickness and how much snow has fallen in the last 100 years and the temperature. Her commute north is shorter than her southern sojourn, just 2,000 miles to the town of Kangerlussag and another 3,000 to the spot where they measure the ice.
Here are a few things that Bell thinks people who live on the banks of the Hudson should keep in mind when contemplating the impact of global weather systems:

Integrate your concern for the environment into your life whatever it is… art, journalism, business… we have to embrace change and move away from a lifestyle based on carbon fuels.
Encourage kids to study science and engineering…. we need more really smart people working on the planet as a system if we want to keep it as a habitable place.

When you are standing in Memorial Park, Bell has a simple way to fathom the elevated height of the river. “Put your hand just below your knee…. the water has gone up that far since 1900.”  Bell hopes that local governments will be mindful of this accelerating trend and place critical infrastructure above storm surge levels.

Even though she already gives to the fight against global climate change at the office, Bell’s activities extend beyond the traditional scope of scientific research. Bell was the director of the ADVANCE program at Columbia’s Earth Institute from 2004-2011 that increased the participation and advancement of women scientists and engineers at the University. She was also instrumental in the development of the International Polar Year 2007-8.
Most of us are as likely to walk on the moon, as we are to step onto the ice at the South Pole. But what happens underneath Antarctica’s frozen surface shapes our future. Which is why we are fortunate that one of our neighbors is willing to make the trip for us. Let’s just hope that policy makers have the wisdom to comprehend the implications of her findings and the integrity to take corrective action.
