Devastating Fires Might Become More Common In Hawaii

As of Friday morning, at least 55 were dead and thousands were seeking shelter on Maui, after wildfires tore across the Hawaiian island. Officials there say that the fires, once rare, have caused billions of dollars in damage, and the Biden administration has made federal disaster relief available.

The fires were driven by strong, dry winds from nearby Hurricane Dora, and were made worse by ongoing drought conditions. The region has grown hotter and drier, and highly flammable invasive grasses have been crowding out native vegetation.

Bethany Brookshire, freelance science journalist and author of the book Pests: How Humans Created Animal Villains, joins Ira Flatow to talk about this story and others from this week in science news, including an investigation into unknown genes in our genome, a 390 million year-old moss that might not survive climate change, and a fish that plays hide and seek to get to its prey.

A Tuna’s Reel Life Adventures

Bluefin tuna is typically sliced into small pieces, its ruby red flesh rolled into sushi. But don’t let those tiny sashimi slices fool you. Bluefin tuna are colossal creatures—on average, they’re about 500 pounds. The biggest one ever caught was a whopping 1,500 pounds. They can travel thousands of miles at breakneck speeds, and their skin changes color!

The fish, once in danger of extinction, have now rebounded due to a combination of scientific advances and possibly as a result of climate change.

Ira talks with Karen Pinchin, science journalist and author of the new book, Kings of Their Own Ocean: Tuna, Obsession, and The Future of Our Seas about a tuna nicknamed Amelia who traveled across the world, the fisherman who tagged her, and what their stories can help us better understand about the mighty fish.

Preserving Acadia National Park’s Vanishing Birdsong

Acadia National Park in Maine is home to more than 300 bird species. Climate change is affecting the range of many of these birds, to the extent that some may not be found in the area in the future. A team of volunteers has made it their mission to record as many bird sounds as possible—while they still can.

Laura Sebastianelli is the founder and lead researcher of the Schoodic Notes Bird Sounds of Acadia project. She’s helped collect more than 1,200 bird sounds on tape, with the hopes of aiding future researchers. Sebastianelli joins Ira to talk about the project.

World’s Richest Lithium Deposit Faces Opposition To Mining

Five years ago, professional gem hunters Mary and Gary Freeman stumbled upon the richest known lithium deposit in the world in the woods of western Maine. Lithium is a silvery metal many consider to be key to the transition to a clean energy future, thanks to its role in technology like lithium-ion batteries.

The Maine deposit could be a way for the United States to be independent in their lithium sourcing. But there’s stiff opposition to digging up the mineral within Maine.

Kate Cough, reporter and enterprise editor for The Maine Monitor, reported this story in collaboration with Time Magazine. Cough is a Report For America corps member. She joins Ira to discuss the debate.
