The Oceans Are Getting Hotter—And Greener

It’s hot out there, and more so than normal July weather. It’s estimated that more than 100 million Americans are under heat watches, warnings, and advisories, spanning the west coast and southern states. Not only is the land hot, but the oceans are, too. The water temperature near the Florida Keys this week reached 96.8 degrees Fahrenheit, just shy of the record for global ocean temperature.

A warmer climate is having some visual effects on our oceans, too. The color of the ocean surface near the equator has gotten greener. The culprit? Phytoplankton, which are full of the pigment chlorophyll.

Joining Ira to talk about these stories and other science news of the week is Rachel Feltman, Editor at Large for Popular Science and host of the podcast “The Weirdest Thing I Learned This Week,” based in Jersey City, New Jersey.

Understanding The Reasons For The Mental Health Crisis In Youth

You’ve probably read the headlines about a spike in youth suicide rates, or about how social media and screen time are exacerbating teen anxiety and depression. Or maybe you read about the shortage of services for kids who need mental health treatment, waiting in emergency rooms for inpatient beds to open up.

And of course the pandemic accelerated all of these issues, leaving kids who might have been already struggling without the support of friends and teachers in their school communities.

Ira takes a closer look at what’s driving these trends with Dr. Patricia Ibeziako, associate chief for clinical services in the department of psychiatry and behavioral services at the Boston Children’s Hospital and associate professor of psychiatry at Harvard Medical School and Dr. Tami Benton, psychiatrist-in-chief in the department of child and adolescent psychiatry and behavioral sciences at the Children’s Hospital of Philadelphia and professor of psychiatry at the University of Pennsylvania’s Perelman School of Medicine.

Rewriting Sharks’ Big, Bad Reputation… For Kids

It’s that time of year when sharks are on our minds. Summer is filled with Shark Week content, viral reports of attacks, and shrieks on the beach when someone spots a fin in the water… from a dolphin.

But sharks don’t deserve this bad reputation. They are beautiful, fascinating, and—more than anything—the Earth needs them. A new children’s book called “Mother of Sharks,” by Melissa Cristina Márquez, aims to teach kids exactly that.

Ira talks with Márquez, a shark scientist and wildlife educator, about the book, shark conservation, and why she loves sharks so much.
