Join Jeff Corwin as he explores climate change impacts, from California's drought-stricken Sierra Nevada and the Caldor Fire's aftermath, where he meets firefighters, to Washington State. There, he highlights conservation efforts for the resourceful American beaver and the endangered Pygmy rabbit.

In Washington, Corwin joins the Tulalip Beaver Project, which humanely relocates beavers from conflict areas. Beavers are vital ecosystem engineers, building dams that increase water storage, filter pollutants, promote biodiversity, and create crucial salmon habitat. Nearly hunted to extinction, these resilient animals are now recovering, with the Tulalip Tribal Community leading successful wildlife management and research efforts.

Human objects in space are creating dangerous clutter. MIT Assistant Professor Danielle Wood advocates for sustainable space technology, stressing the need to respect both people and the environment in future missions. This approach is crucial for managing the "industrial waste" accumulating beyond Earth.

One promising solution involves a wax-based fuel for satellites, made from beeswax and candle wax. This less toxic and more affordable alternative would help bring objects closer to Earth for safe deorbiting and destruction, offering a sustainable way to address space debris.

Jeff Corwin joins conservationists in California to protect pinnipeds, including elephant seals and sea lions. Organizations like the Marine Mammal Care Center and Defenders of Wildlife are crucial in rescuing and rehabilitating these animals, which face severe threats from climate change, overfishing, habitat loss, and plastic pollution.

Corwin assists Dr. Lauren Palmer and Andy Johnson in rehabilitating four malnourished California sea lion pups, one of whom ingested plastic. After critical care, tagging, and weighing, the pups are successfully released back into the wild. This effort underscores the vital role of conservation in giving endangered animals a second chance and addressing environmental challenges for ecosystem health.

Host Jeff Corwin celebrates the Endangered Species Act (ESA), landmark 1973 legislation protecting vulnerable wildlife and ecosystems. The bald eagle, once near extinction, exemplifies the ESA's success, having recovered and now thriving across the U.S.

The ESA also protects sea turtles, with Florida's beaches being globally vital nesting sites. Conservation efforts, like Boca Raton's beachfront parks, are crucial. While only 1 in 10,000 hatchlings survive to adulthood, protecting their habitat allows these keystone species to flourish. All six sea turtle species nesting in America are protected by the ESA.

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.
