Rerun: Using Groundwater to Heat and Cool Buildings


Heat pumps are a more sustainable and efficient way to heat homes than to conventional gas heat, but they’re often too expensive for homeowners to install. Meet the GeoGrid, an underground geothermal heat pump network that could make the technology more efficient and accessible. Home Energy Efficiency Team (HEET) is a nonprofit working with utilities to develop GeoGrids in residential neighborhoods. We spoke to HEET Executive Directors Audrey Schulman and Zeyneb Magavi about heat pumps and the advantage to connecting them via a GeoGrid approach.

Hip Hop 4 Change: Using Art Activism to Combat Climate Change

Hip Hip is not just a music genre; it was born as a way for the oppressed to speak about and connect over the socio-economic injustices they experienced. In this episode we delve into how today’s youth can use art, including Hip Hop, to engage critically with the world around them. We spoke with Khafre Jay, the founder and executive director of the nonprofit Hip Hop For Change, about how he uses Hip Hop for climate activism.

Resilience Hotspots: Nature’s Role in Urban Climate Adaptation

Nature-based solutions to climate change, such as “Resilience Hotspots,” can enhance climate resilience by restoring and maintaining pockets of nature, such as wetlands and urban green spaces, to counteract storm surges and urban heat islands. Integrating these natural defenses into urban planning, while emphasizing community equity, not only mitigates climate impacts but also promotes climate justice.

RERUN: Using CRISPR to Fight Climate Change with Professor Kris Niyogi


When plants photosynthesize, they temporarily remove carbon dioxide from the atmosphere. Could we use gene editing technology CRISPR to enhance photosynthesis and increase the amount of carbon dioxide they remove? UC Berkeley biology Professor and photosynthesis expert Kris Niyogi thinks so, and he says it could fight climate change and enhance food production at the same time. In this episode, Climate Break speaks to Professor Niyogi about his lab’s early-stage research into CRISPR, photosynthesis, and applications to climate change.
