Engaging With Heart: Key to Ensuring a Better Future for All

June, 2023

How can we ensure a better future for all? This question is at the core of so much of our work as environmental and sustainability professionals. I was recently asked to address this question to set the stage for an environmental studies and science conference for graduate students whose conference theme was Exploring the Margins: Environmental Research for a Better Future.

Building Resilience: Mending Nets and Cultivating Sustainable Futures

May, 2023

In our first GCSE essay last October, we presented a method for Reframing Sustainability Education to include the weaving of Indigenous knowledge systems and decolonizing higher education as a necessary and critically missing piece of our work and practice in sustainability.

Opening New Pathways for Societal Impact through Actionable Knowledge Production

April, 2023

Science should help inform solutions to the many urgent societal challenges we face, from climate change to sustainable development, to combating disease and improving public health, to creating sustainable and secure food, water, and energy systems, to stemming biodiversity loss, and much more.


February, 2023

As a sustainability program director, Dr. Lee Ball feels a palpable tension between the urgency for aggressive climate action and the hope for a more sustainable future. For many individuals working in higher education, hope fuels their idealism in a world dominated with ROIs and VLRs and SDGs…and with competing priorities and fear. Lee details a field riddled with obstacles, yet required to provide reliable "real world" solutions. He provides a call to action for not just "sustaining the sustainers", but for learning to regenerate together.

Unpacking the UNEA Resolution to End Plastic Pollution

January, 2023

GCSE Senior Fellows Mary Ellen Ternes, Esq. and Jeffrey Seay, Ph.D. unpack UNEA Resolution 5/14 entitled “End plastic pollution: Towards an international legally binding instrument." The authors summarize key challenges with plastic, such as its often toxic nature and its disparate effects on developing nations. The essay also reviews results from the first Intergovernmental Negotiating Committee session (INC-1), GCSE’s involvement with INC-1, and GCSE’s contributions to critical scientific consensus on plastic pollution.

Climate Justice, Societal Transformation and the Role of Higher Education

November, 2022

The science is clear.  To reduce human suffering from the climate crisis, humanity must implement a coordinated global plan to phase out fossil fuels.  Exploration of new fossil fuels must end, extraction of existing fossil fuel resources must be rapidly scaled back, and new transformative public investments are needed.  Despite the scientific clarity of this basic, practical need for climate justice, powerful corporate interests continue to exert their influence to resist change.  Unfortunately these corporate interests have also been wielding their powe

Walking the Talk: A Post-pandemic Campus-Community Action Agenda for Sustainability and Resiliency Education

October, 2022

Sustainability in Higher Education stands at a crossroads: do we return to the way things were….or do something different? Covid forced communities to reflect on their ability to respond to disasters and has shed light on how to create more resilient social systems. How do we echo this restructuring and “build back better” for Sustainability in Higher Education? 

The Influence of United States Leadership on Multilateral Climate Decision-Making Processes

September, 2022

Climate change impacts are visibly worsening around the globe and implementing mitigation and adaptation strategies requires unprecedented international cooperation. Historically, decision-makers have worked together to address climate change through multilateral and international treaties that have domestic policy implications for the signatories.

Land and Water Management in the Ethiopian Highlands to Protect Ecosystem Services

July, 2022

As high-income countries around the world increase environmental protections, ecosystem services are deteriorating where most needed - people in low- and middle-income countries rely heavily on ecosystem services. In Africa, human activity is changing water use, as land is put under cultivation and dams developed for energy and irrigation. Most often, ecosystem health is ignored in the course of development.

Mitigating Health Impacts from Climate Change through Managed Retreat

June, 2022

There is no denying that climate change is one of the most potent drivers of human migration. The World Bank’s latest report projects that 216 million people across six world regions will move within their countries by 2050 (Clement et al., 2021).

A Perfect Storm: Climate Change, Biodiversity Loss, Global Water Scarcity

May, 2022

Almost all environmental and economic indicators projecting our world’s future show that we are headed towards a perfect storm by mid-century. This bleak outlook is the result of increasing global impacts of climate change, the distinct probability of a massive extinction of species, and a world without adequate freshwater resources to sustain life.

Saving Nature with Nature

April, 2022

Ecosystem services are the gifts from nature that keep on giving. Coupled with the mobilization of global actions at scale, the combination can disrupt the current destabilization of the Earth’s climate system. This level of unprecedented actions is imperative to curb the staggering loss of biodiversity and to determine pathways to recover and restore what’s already been lost.

Protecting the Biosphere: Science Diplomacy in Action to Combat Plastic Pollution

March, 2022

Demonstrating that global consensus is achievable most especially when science is engaged in the process, 175 nations agreed to determine a legally-enforcing treaty to manage plastic pollution to enter into force by 2026. Likened to the Montreal Protocol as a swift effort by nations in science diplomacy, the End Plastic Pollution resolution requires concrete global action to mitigate plastic pollution by nations.
