NASA scientists utilized 30 years of Landsat satellite data to track vegetation changes across 4 million square miles of Alaska and Canada. Their findings reveal a significant "greening" trend, with 30% of the area showing increased vegetation, while only 3% experienced "browning."

This pioneering study, the first to provide continent-scale detail alongside local information, underscores the impact of rapid Arctic warming. Elevated temperatures lead to extended growing seasons and altered soils, transforming tundras into shrublands. Future research will investigate local factors influencing these greening patterns and explore forested regions.

"Billion Dollar Crop," a 1994 Australian documentary, explores the history, diverse uses, and future of cannabis, focusing on the versatile and potentially revolutionary plant's potential.

The film highlights how recently developed, non-drug hemp varieties are being researched and cultivated globally for their versatile qualities and environmental benefits. It showcases hemp as an industrial fiber, offering alternatives to wood for paper, cotton for clothes, and plywood for construction, thereby benefiting forests and topsoil.

Produced with Michael Cordell and Jeffrey Bruer, and directed by Barbara Ann Chobocky, the DVD is available from Bull Frog Films.

Dr. Jennifer Smith and entrepreneur Brant Chlebowski discuss their collaborative applied aquaculture research on commercially valuable seaweeds. This groundbreaking work sparked the formation of the California Seaweed Company and initiated new research in Smith's lab focusing on local seaweeds for food and feed applications.

This presentation was recorded on March 11, 2019, as part of the Jeffrey B. Graham Perspectives on Ocean Science Lecture Series. For more information, visit UCTV.

This talk explores Sunset Crater, Arizona's youngest volcano, erupted 940 years ago, impacting the Sinagua people. Geologist Dr. Jeffrey Meyer will share its story and his work mapping the unique Bonito lava flow, notable for traveling uphill.

Understanding this flow aids hazard prediction and interpreting past flows on Earth, the Moon, and other planets. Dr. Meyer, a retired geology instructor, became curious about the Bonito flow, leading to detailed mapping via Lidar.
