Scientists recently discovered bats, like Tuvan throat singers and death-metal vocalists, produce sound using ventricular folds instead of vocal cords. A Danish biologist found bats use these for low-frequency calls. With their ability to also make extremely high-pitched calls, bats possess an unparalleled vocal range. The Center for Biological Diversity argues this makes them more akin to grindcore vocalists, who utilize both very low and very high frequencies.

The Center for Biological Diversity, a 501c3 nonprofit, works to secure a future for all species through science, law, and creative media. Check out our video to hear biodiversity-loving grindcore artists and see brutally cute bats. Learn more at biologicaldiversity.org or email us at center@biologicaldiversity.org.

As climate challenges escalate, communities increasingly recognize that effective action and resilience hinge on ecological boundaries—watersheds, food, energy, and culture sheds—rather than just political maps. This bioregional perspective is crucial for redefining governance and building political-ecological alliances that prioritize equity and justice.

A visionary group of climate action organizers, including Indigenous leader Eriel Deranger, Rights of Nature attorney Thomas Linzey, climate justice lawyer Colette Pichon Battle (Taproot Earth), and OneEarth founder Justin Winters, illuminate pathways for practical climate solutions and emerging eco-governance.

This conversation took place at the Bioneers 2025 Conference. Explore more keynote talks and discussions at bioneers.org.

ClimateWise and the Association of British Insurers (ABI) hosted a COP26 event on November 3, 2021, titled "Risk Sharing in the Climate Emergency." The event convened senior representatives from insurance, regulatory bodies, and governments to discuss their crucial roles in addressing the global climate challenge.

The University of Cambridge Institute for Sustainability Leadership (CISL) and ClimateWise presented actionable recommendations. Their work outlines priorities for urgently expanding risk sharing and insurance systems as an essential climate policy response. These recommendations provide a pathway to immediately quantify, manage, and reduce climate risks, and to integrate climate policy and regulation for a resilient, net-zero, and just transition across all economies.

Women worldwide, particularly in the "developing world," disproportionately bear the brunt of climate change and environmental degradation, yet their voices are frequently overlooked. Climate, physical, and psycho-spiritual health are deeply interconnected, not separate issues.

A panel of leading women activists, including Zainab Salbi, Nina Simons, Justin Winters, Kahea Pacheco, and Helena Gualinga, explored climate's impact on women. They advocated for women's full inclusion in all climate solutions, linking these struggles to personal healing and authentic global change.

Endangered Blanding's turtle hatchlings begin their journey into the wild. These turtles can live 80 years, but their population is critically threatened by predation, disease, habitat destruction, and human collection.

In 2011, a Center petition secured CITES protection for Blanding's turtles. The Center, joined by renowned scientists like E.O. Wilson, further petitioned in 2012 for U.S. Endangered Species Act protection for the turtle and 52 other threatened amphibians and reptiles.

While not yet federally protected in the U.S., Blanding's turtles are safeguarded by state laws in several states.
