With their long tusks, narwhals are unique whales that live in the Arctic Ocean. But as climate change causes global temperatures to rise, less and less sea ice is covering the Arctic Ocean each year. Narwhals are left vulnerable without the ice, which historically provided them with safe areas to roam out of reach of their natural predators, killer whales. And humans are taking advantage of the clearer water, searching and drilling for oil and hauling cargo.

People imagined artificial intelligence as far back as the early 1900s. In the 1940s, the first programmed computers were created. Over time, scientists created better computers modeled after the human brain. These days computers can create art or help students with their homework. What will they do in the coming years? Dive in to learn about the past, present, and future of AI.

Engineers and scientists have been developing AI since the 1950s, and it has come a long way since then!

AI’s creative potential can be exciting, but some also have ethical concerns. Check out how AI is changing the art world, sparking both new artistic possibilities and complex ethical questions.

The Great Bear Rainforest is a majestic place full of tall trees, huge bears and endless schools of salmon. Award-winning photographer and author Ian McAllister tells the story of a lone wolf who swims to one of the small islands that dot the rainforest's coast. The island provides him with everything he needs—deer, salmon, fresh water—everything, that is, but a mate. When a female wolf arrives on the island's rocky shores, she and he start a family and introduce their pups to the island's bounty.

A Whale’s World follows a pod of spy-hopping orcas as they explore the ecosystems of the Great Bear Sea while hunting for their next meal. Past rocky shores and through kelp forests, they observe foraging wolves, hungry grizzly bears, curious black bears, graceful fin whales, splashing porpoises, slippery seals and other members of the Pacific coastal food web. The book gives listeners a fun introduction to the many ways that marine and land animals interact with their environments and with each other.
