Deep Dialogues and Expert Series

Deep Dialogue – 7/25/22 and 8/8/22 – Residential Building Decarbonization

Roger Luckmann, Ed Woll, and Arnie Epstein of our Research Team have been exploring the challenges of weatherizing and electrifying heating in residential buildings.  The building sector is the second largest source of greenhouse gas emissions in the state and small residential buildings account for the major share of building emissions.  This is a two-part presentation.  In the first part, the nature and scope of the challenge, is reviewed along with an overview of residential building weatherization and heat pump retrofits.

The video for the first part of this series is here.  The slides from the presentation are here.

In Part 2 of the series we discussed our view of approaches to meet the emissions reduction targets for these buildings and review the scenarios identified by the administration in their recently released 2030 CECP (Clean Energy and Climate Plan).  

The video for Part 2 of this series is here. The slides from the presentation are here.

Deep Dialogue – 6/27/22 – Representative Tackey Chan

He came at us and probably comes at everyone with a mile-a-second intelligence and insight on all things climate. He’s got so much knowledge on so many topics, you have to be willing to press pause while watching the video to think over what he just said. You may not agree with everything, but the purpose of our Deep Dialogues is to engage on these key topics.  The video of this presentation and discussion is here.

In Honor of Larry Rosenberg – The Climate Crisis

This Deep Dialogue was held in honor of Larry Rosenberg, who was a founding member of the Massachusetts chapter of ECA, and served on both the leadership and research teams.  Larry died of cancer on May 2, 2022, the day after he finished editing his paper on climate change: “The Climate Crisis: Impending Catastrophe and Possible Responses”.  After working much of his life on a number of different causes, Larry recognized climate change as the greatest threat to humanity and the world. To honor Larry and his work and to inspire and rededicate us to the fight against climate change, this Deep Dialogue focusses on the presentation of Larry’s paper and what we can all do to continue his work. The meeting begins with remembrances of Larry from five people who knew him well and were inspired by his activism.  Another group of ECA members share presenting Larrys’ paper, which can be seen as a slide show as they speak. The paper is an overview of the current state of the climate crisis, the  expected consequences of it, and the many ways we can address it.  The paper covers both accepted and controversial means of fighting climate change, and urges us to keep all options open, as our time for reducing catastrophic harm has grown so short. Larry’s paper is here and the video is here.

Climate Change in New England

Our April Deep Dialogue featured a presentation and Q&A with guest speaker Dr. Stephen Young, professor of remote sensing and environmental sustainability at Salem State University. Dr Young focused on his recent publication “Overall warming with reduced seasonality: temperature change in New England, USA, 1900 – 2020”, and discussed the current and impending effects of continued warming in New England. His presentation included photographs of climate change impacts on the North Shore.

Why we need lifestyle change to fight climate change

Climate change is often seen as a challenge that can be met by technological solutions like renewable energy. While these are necessary parts of the solution, they may not be sufficient, especially in a world where more and more people seek to consume more materials and energy. Yet changes in lifestyles to reduce our carbon footprints is a difficult topic for policy makers and activists.

At our March Deep Dialogue, we heard about the challenge of changing lifestyles from Newton climate activist and scientist, Philip J. Vergragt PhD, who has spent years researching “sustainable consumption” and “sustainable lifestyles.” His presentation explored if and how our wellbeing can be maintained – and improved – while reducing our “consumption carbon footprint.” Watch the presentation video, with the Q&A and informative discussion here, and access the presentation slides here. You can also reach Philip directly. His email is pvergragt@outlook.com.

Deep Dialogue – 1/24/22
Fresh Water and Climate Change

Did you know that only 2.5% of water on Earth is fresh water? And only a small portion of that fresh water is available, at the surface in lakes and rivers, and in groundwater, to sustain human, plant and animal life. Floods, drought and extreme weather are much in the news, as climate change exacerbates our water problems.  

At our January conversation series, Betty Krikorian of the ECA Mass Research Team took us on a deep dive into Fresh Water and Climate Change, with a fascinating presentation that helped us understand the increasing threats to our precious fresh water resources. She explored water management and its potential for climate change mitigation, highlighting the water challenges in three very different geographical regions of the United States.

The Role of MA Public Forests in Addressing the Climate Emergency

Massachusetts has 1 million acres of public forests, which play a critical role in removing and storing carbon, and helping to achieve the net-zero climate goals of the Massachusetts Next Generation Roadmap Law. So why does the Department of Conservation and Recreation (DCR) persist in commercial logging of our public forests, destroying thousands of acres and intentionally targeting the largest mature trees, while violating numerous laws and regulations? How would pending forest legislation (H.912 and H. 1002) change outdated laws and make DCR accountable to the public, protect our trees and wildlife, and address the climate crisis? What can you do to support passage of these important bills?

ECA Mass Legislative Team member and Forest Bill Manager, Glen Ayers, answered these questions and much more, analyzing the past 10 years of DCR logging in state parks and forests, and the changes we need to meet our climate goals. His eye-opening presentation is essential viewing for everyone who cares about forests and climate.

You can watch a video of Glen’s presentation, with all the Q&A and discussion, here. Glen’s presentation slides, with dozens of useful links to legislation and regulations, scientific research, and many other resources, are available here.

Deep Dialogue – 11/30/21
Net Zero and Carbon Dioxide Removal

The IPCC (Intergovernmental Panel on Climate Change) determined we must keep global warming below 1.5 degrees Centigrade to avoid some of the worst impacts of climate change.  To do this our CO2 emissions must be “net zero” by 2050.

Arnie Epstein of our Research Team discussed what net zero means and why the target is net zero and not simply zero emissions.  Why net zero entails removing CO2 from the atmosphere and why this is needed regardless of how successful we are in reducing worldwide emissions.  The amount of CO2 removal required is covered along with the approaches and outlook for achieving it.  Finally, we discussed the moral hazard represented by CO2 removal and ways to avoid becoming over reliant and not acting with the urgency needed to reduce CO2 emissions.

The video of this deep dialogue, including a lively discussion, is below. The slides from the presentation are here.

Deep Dialogue – 10/25/21
Natural Solutions: A Path to Mitigate both Climate Change and Biodiversity Loss

It has become clear that climate change and biodiversity loss present equal threats to human existence and a habitable planet. These interrelated crises need to be acted on simultaneously to avoid worsening them both. 

Amy Meltzer of our Research Team gives an introduction to the biodiversity crisis, and discusses the crucial role of land based ecosystems in both carbon sequestration and biodiversity support. She shows how actions informed by an understanding of ecological relationships can improve carbon sequestration and increase climate resilience, while lessening the threat of species extinction. She discusses actions that can be taken through policy at all levels of government, and by individuals and community groups. You will find resource slides at the end of the slide show. The slides from the presentation are here.

Deep Dialogue – 9/27/21
Hydrogen and the Clean Energy Transition

We’ve all heard of hydrogen, but did you know there’s green hydrogen (and blue, turquoise, and grey hydrogen)? Did you know that hydrogen may be one of the energy sources to help address the climate crisis and get us to net-zero carbon emissions? Our September ECA Mass Deep Dialogue conversation series focused on the potential role of hydrogen in the clean energy transformation.

We heard from hydrogen expert Brad Bradshaw, president of the Hydrogen Energy Center, a non-profit organization that conducts research and provides educational forums on the application of hydrogen. He explained how the various types of hydrogen are produced, stored, and transported, and emerging applications for renewable hydrogen – and the key role it can play in decarbonizing our economy, particularly in “difficult to electrify” sectors. Brad brought clarity to a complicated and controversial subject, and graciously stayed on for an extended Q&A session after his presentation.
