Tornado Clusters and Climate Disruption / Beyond the Headlines / Oceans Losing Oxygen / Note on Emerging Science: Matchmaking for a Frog Named "Romeo" / Cloning Giant Sequoias / In Search of the Canary Tree In this episode, climate disruption -- and resiliency.

Outbreaks of tornado clusters are being stoked by climate change, with 40 on the day that the strongest one devastated Lee County, Alabama.

Meanwhile, warmer water holds less oxygen than cooler water does, so as climate change warms the oceans, they're losing oxygen. Pollutants like nitrogen and phosphorus, also contribute to oxygen-starved "dead zones."

The warming planet is affecting forests, too, but they can be amazingly resilient. A nonprofit is working to give Coast Redwoods and Giant Sequoias a leg up on resiliency by cloning the hardiest trees.

And the author of the new book, "In Search of the Canary Tree," shares how forests, and communities in Southeast Alaska, are transforming in the wake of mass die-offs of giant cypresses known as yellow cedars.

All that and more, in this episode of Living on Earth from PRI.
