Religion in Times of Earth Crisis: Apocalyptic Grief: Reckoning with Loss, Wrestling with Hope

Human-caused climate change already contributes to manifold global disasters. As the planet inevitably continues to warm, these disasters will be routine and unrelenting. Addressing the reality of loss must become a basic spiritual task of our climate present and future, along with summoning the resolve to respond to all our losses. In this session, Matthew Ichihashi Potts will consider the apocalyptic roots of the Christian tradition in order both to diagnose how Christianity has contributed to the present crisis, as well as to suggest possibilities for a different way forward. Through particular attention to grief and hope as religious categories, and with specific reference to various moments and movements from within the Christian tradition, Potts will reflect upon the spiritual crisis at the heart of climate catastrophe and suggest the potential for a religious response.

Speaker: Matthew Ichihashi Potts, Plummer Professor of Christian Morals and Pusey Minister in the Memorial Church
Moderator: Diane L. Moore, Diane L. Moore, Associate Dean of Religion and Public Life

Toast to MethaneSAT: Tackling Methane Emissions from Orbit

greenhouse gas emissions

Join us for a historic moment as we celebrate MethaneSAT, a groundbreaking satellite that will track methane emissions on a global scale. Food and beverages will be served as we toast to MethaneSAT’s upcoming launch.

MethaneSAT is the result of a collaborative effort between the Environmental Defense Fund, space technology experts, and faculty and researchers at the Harvard Paulson School of Engineering & Applied Sciences and the Harvard & Smithsonian Center for Astrophysics. The cutting-edge satellite will play a pivotal role in addressing one of the most pressing climate change challenges of our time – methane emissions. For the first time, MethaneSAT will provide corporations and governments around the world with both granular and global data on methane leaks.

All members of the Harvard community are welcome to join! Registration required.

Religion in Times of Earth Crisis: The Practice of Wild Mercy: Something Deeper Than Hope

Can personhood be granted to mountains, lakes, and rivers? What does it mean to be met by another species? How do we extend our notion of power to include all life forms? And what does a different kind of power look like and feel like? Wild Mercy is in our hands. Practices of attention in the field with compassion and grace deepen our kinship with life, allowing us to touch something deeper than hope. Great Salt Lake offers us a reflection into our own nature: Are we shrinking or expanding?

Landscape Sketching

Landscapes are an appealing subject for drawings, but it can be difficult to know where to start. In this program we will learn how to select a landscape, create a sense of depth and volume, and use a variety of marks to capture a dynamic variety of textures.
