NASA reported that Earth's average surface temperature in 2022 tied with 2015 as the fifth warmest on record, continuing the planet's long-term warming trend.

Global temperatures were 1.6 degrees Fahrenheit (0.89 degrees Celsius) above the 1951-1980 baseline average, according to scientists from NASA's Goddard Institute for Space Studies (GISS).

The Atlantic Meridional Overturning Circulation (AMOC) comprises two limbs. Its upper limb transports warm, tropical waters northward, releasing heat influencing European weather. The lower limb carries cold, dense waters southward at depth.

Driven by solar radiation, the AMOC's upper limb features vigorous currents like the Gulf Stream, flowing north along the Atlantic's western boundary. These currents, forming eddies, carry heat towards higher latitudes, reaching the Nordic Seas to cool and densify.

In regions like the Labrador Sea, these cooled, dense waters plunge via convection to 1000-2000m. This forms the Deep Western Boundary Current, the AMOC's lower limb, flowing slowly southward along the continental slope. Further south, this deep flow is disrupted by topography and eddies, losing its structure.

Dr. Shane Gero's groundbreaking research deciphers sperm whale communication, revealing their complex, intelligent lives and cultures. His work suggests whales are "people too," urging us to learn deep listening for respectful coexistence.

Gero, a Canadian whale biologist and National Geographic Explorer, founded The Dominica Sperm Whale Project and leads biology for Project CETI. His science, which formed the basis for the Emmy-winning series *Secrets of the Whales*, is transforming our understanding of marine life. Learn more at shanegero.com.

Indigenous science has long protected ecosystems, yet mainstream environmental solutions often overlook it. As climate crises intensify, young activists are reclaiming these knowledge systems, challenging colonial frameworks, and fostering global solidarity.

Drawing from her family’s history and work at UC Berkeley and Project Planet, Shreya Chaudhuri explores how youth-led movements are centering Indigenous knowledge to reshape climate justice. True sustainability means reclaiming these foundational roots, not inventing new solutions. The critical question is: will we listen?

Clean energy entrepreneur Danny Kennedy explores the promise and challenges of the global transition to renewable energy. He asserts that while the shift is urgent, millions of clean energy entrepreneurs and startups, partnered with determined Indigenous leadership worldwide, can achieve this transition in time to avert climate breakdown.

Kennedy, an eco-activist turned clean-technology entrepreneur, is a leading figure in capitalizing on the green economy. He currently serves as CEO of New Energy Nexus, a global nonprofit that provides funds, accelerators, and networks to drive clean energy innovation and adoption.

Ben Jealous, former NAACP President and current Executive Director of the Sierra Club, examines how the green economy drives job creation and transforms industries, including renewable energy and electric vehicles.

He debunks myths that this transition will lead to job losses or take too long, showcasing how innovation fuels economic growth. Jealous also highlights the health benefits of cleaner air and reduced pollution, such as lower rates of asthma and heart disease. He underscores how the green economy reshapes industries, improves workforce opportunities, and enhances public health outcomes.

"The Green Buffalo" is a 2024 short documentary, approximately 20 minutes long, produced by Patagonia Workwear and directed by Joel Caldwell. Monika McClure also served as a producer.

The film focuses on the Lower Sioux Indian Community in Minnesota and their innovative use of industrial hemp to create hempcrete. This sustainable, low-energy building material offers a better-performing alternative for construction. The title symbolizes hemp becoming a vital resource for the community's housing and well-being, much like the historical role of the bison.

Ecological futurist Tariq Al-Olaimy highlights "spiritual infrastructure" as a key, often-overlooked resilient system. He's observed how faith networks—like church basements and mosque yards—sustain disaster-stricken communities long before formal aid arrives.

Drawing on a decade with global faith coalitions, Al-Olaimy explores why spiritual traditions are uniquely equipped to navigate moments of collapse. He suggests aligning our inner values, economies, and ecosystems is essential for restoring life on a changing planet. (Recorded at TED Countdown Summit 2025 on June 18, 2025)
