Environmental Learning and Stewardship in Howard County, MD

HoLLIE Moves Forward…


HoLLIE will not be holding our traditional 8-week institute Feb-Mar 2023. 


Starting with the 2020 COVID outbreak, HoLLIE pivoted to make our programs all virtual.  Now we are looking at new ways to continue our mission of providing environmental education while fostering community engagement and service. 


We plan to send past participants a questionnaire asking for your input on the ideas we have for moving forward.

Thank you for caring about HoLLIE and caring for the Environment!  You may continue to access the recordings from our 2022 and 2021 virtual programs below.

HoLLIE 2022 Virtual Lecture Series

Our Changing Climate: Science, Policy, Justice, & Action

Session Abstracts and Recordings:

March 3 


Observing the Earth through the Eyes of Satellites

Claire Parkinson, Ph.D.

Climate Change Senior Scientist, NASA’s Goddard Space Flight Center 

Starting in the second half of the twentieth century, satellites have opened a new, broad vista on what is occurring on our ever-changing planet. This talk will discuss some ways through which this is done and will present a wide range of illustrative examples, from individual events such as fires, hurricanes, volcanic eruptions, and coccolithophore blooms, to changes in the Antarctic ozone hole and long-term trends such as sea level rise, increases in atmospheric temperature, carbon dioxide, and methane, and decreases in land ice and sea ice. With satellites, we can be more certain than ever before about the changes occurring on our planet.

Environmental Justice in a Warming Climate

Vernice Miller-Travis  

Executive VP, Social Justice Lead, Metropolitan Group

How toxic and pollution-causing industrial practices more severely impact the health and well-being of those living closest to these sources.  As a result,  these communities are more vulnerable to the additional pressures of climate-change, with its excessive wind, rain, snow, drought, etc..  These communities need a wide variety of additional resources to lift them up.

You Have the Power to Make a Better Climate Future

Sara Via, Ph. D.

Professor & Climate Extension Specialist, University of MD College Park

A surprising 42% of all US greenhouse gas emissions trace back to individual actions in one way or another.  This means your choices can make a real difference.  When your furnace or vehicle needs to be replaced, your choice matters.  When you choose whether to replace your old appliances with an Energy Star refrigerator or high-efficiency washer, your choice matters. What you buy, what you eat, even how you handle leftover food all matter. Most of these choices aren’t hard, and some can  improve your health and save you money or time. In this talk, you’ll learn some easy actions that can make you part of a growing group of changemakers who are making a better climate future.

Living Our Environmental Purpose and Passion

Tracey Manning, Ph.D.

Adjunct Professor, School of Public Health, Univ of MD, College Park

It’s natural to be overwhelmed by the scale and impact of climate change on our environment. However, that often leads people to be frustrated or burnt out trying to do everything they can see. How can each of us discover our strengths and our environmental passion, prioritize where we can make the most impact, and act on what matters most for us to do, individually and with allies? What next steps can we take for a positive impact locally and globally?
