Ilissa Ocko, PhD

CLIMATE SCIENTIST

 

I am a climate scientist on a mission

to translate the best available science into effective, practical, and actionable strategies to curb climate change in the coming decades.

I am passionate about and committed to

communicating complex science to non-experts by combining plain language with storytelling and powerful visuals.

I work closely with

policy and business experts, economists, lawyers, and other scientists to provide climate action guidance for governments, companies, and investors across the world.

Hello! I'm Ilissa.

I am an applied climate scientist passionate about identifying and facilitating the most effective and pragmatic solutions to the current climate crisis. I conduct and have published several policy-relevant scientific research studies where I explore the impacts of human-emitted climate pollutants and their mitigation on climate change both during our lifetimes and for generations to come.

Currently I am a Sr. Climate Scientist and Barbra Streisand Chair of Environmental Studies at Environmental Defense Fund, where I lead our climate science team in pursuing original climate science research and providing guidance for climate change communication and decision-making.

 

I am personally committed to communicating science to non-experts using plain language and powerful visuals. A few years ago I represented the U.S. in an international science communications contest and last year I gave a TED talk on the fastest way to slow down climate change .

HOW TO CURB CLIMATE CHANGE 

My research involves employing reduced-complexity climate models and climate metrics to determine the most effective ways to limit warming in both the near-term and long-term by reducing both short-lived and long-lived climate pollutants, including carbon dioxide, methane, hydrogen, and black carbon.

HOW THE CLIMATE RESPONDS TO CLIMATE POLLUTANTS

My research focuses on exploring the thermal, hydrological, and dynamical responses to both well-mixed greenhouse gases, spatially variable tropospheric aerosols, and stratospheric aerosols.

I LOVE TURNING JARGON INTO PLAIN LANGUAGE

Translating scientific jargon and information into accessible plain language is something that I do often. As a scientist working at an environmental NGO, a lot of my interactions are with non-scientists (policymakers, lawyers, members, donors, and more). I've written a number of blog posts and used to run a Twitter account that shares only "good" climate news. I have also helped develop a climate change exhibit at UCAR/NCAR.

VISUALIZING

MY BIGGEST PASSION IS DESIGNING INFOGRAPHICS

I love to organize complex aspects of climate change and other scientific information into beautiful, accessible graphics as they are a powerful tool for learning and retaining information. My love for art and design coupled with my scientific knowledge makes designing infographics the perfect hobby. Several of my graphics have been published in news and magazine articles, blog posts, scientific papers, and reports, and I used to run an Instagram account where I posted graphics to promote climate and energy awareness.

SPEAKING

I TRY TO INSPIRE AND ENGAGE AUDIENCES OF ALL KINDS

I am a very animated and passionate speaker, and really try to connect with my audience. I've talked to students of all ages, churches, a music festival and rap show, on TV and radio, to banks and lawfirms, and more. I also enjoy participating in science communication challenges and contests, and a few years ago won the NASA-sponsored U.S. FameLab contest (“American Idol” for scientists), representing the USA in the international competition and advancing to the finals.

EXPERTISE
PhD, Princeton University
Atmospheric & Oceanic Sciences 

My dissertation, with Dr. V. Ramaswamy as my advisor, focused on the contrasting and complementary features of climate responses to human-caused scattering and absorbing aerosols. I used global climate models, corroborated by ground-based and satellite measurements, to isolate climate responses to individual aerosols and greenhouse gases. I was supported by the NSF Graduate Research Fellowship, and won the Emerging Alumni Scholars Award. I also received a certificate in Science, Technology, and Environmental Policy from the Woodrow Wilson School.

MA, Princeton University
Atmospheric & Oceanic Sciences

I began graduate school researching aerosols in the Arctic, both how they are transported there from mid-latitudes and how they influence the energy balance. I was supported by the American Meteorological Society Industry/ Government Graduate Fellowship, and specifically, the NOAA Climate Program Office. I also earned two summer school certificates: Arctic Climate Change Certificate from University Centre in Svalbard, and Physics of the Climate System Certificate from Utrecht University.

BSE, University of Michigan
Earth System Science & Engineering

I was fortunate to have some amazing mentors and some incredible internships and research assistantships. Some of my favorite experiences include traveling to Greenland to learn about climate science, interning at the NOAA Earth System Research Lab as a Hollings Scholar (how I met my husband!), and participating in an REU at the University of Michigan Bio Station. Aside from research, I was co-president of the Society of Undergraduate Earth System Scientists and Engineers, and the Chief Meteorologist of a news show on a student-run television network.
