In the 1930s, the US experienced what has been called its greatest ecological disaster, when the dust bowl ravaged the midwest, eroding topsoil, destroying crops, and displacing millions. As climate change exacerbates drought across much of the US in places like Phoenix and the larger Colorado River basin, damaging dust storms and haboobs are becoming more common, leading many experts to ask whether we might be heading into another dust bowl?
In this episode of Weathered, we speak to a leading expert about this growing threat, the various hazards that dust storms pose to our health, and how best to prepare ourselves and stay out of harm's way.

Spoiler Alert: carbon dioxide emissions are causing the planet to get warmer. But we may be able to use chemistry to solve this problem.
Out of Our Elements hosts Caitlin Saks and Arlo Pérez Esquivel, joined by NOVA Producer Alex Clark, investigate how the planet naturally turns CO2 into stone over long periods of time, and how scientists and engineers are trying to speed up this process in hopes of capturing and storing atmospheric CO2.
They’re joined by Cornell University Environmental Engineer Greeshma Gadikota, who illustrates how you can test out a small-scale form of carbon sequestration in your own home, and Lamont Doherty Earth Observatory’s Angela Slagle, who explains...

Horseshoe crabs spend most of their lives in the ocean depths. But every May and June, their spindly little legs will carry them 60 miles or more to congregate on sandy beaches up and down the Atlantic coast. Nowhere are their numbers greater than in Delaware Bay. As many as 30 million crabs — a population the size of Shanghai, China — descend on these shores. What are they all up to?

What can we do about our plastic waste dilemma? Out of Our Elements hosts Caitlin Saks and Arlo Pérez Esquivel join chemist Malika Jeffries-EL in her Boston University lab to explore just what it takes to break down familiar plastics like legos and styrofoam. They also learn why plastic isn’t always recycled—even when it does make it into those familiar blue bins.
Biodegradable plastics on the market today may sound like a fantastic solution to our problem. But there’s a caveat: Outside of special composting facilities, they’re difficult to break down and they can still introduce harmful microplastics into the environment.

Does fire affect climate change? What about extreme wildfire behavior?
A fire tornado, or “firenado,” is exactly what it sounds like: a tornado made out of fire… and it is truly the stuff of nightmares. The most famous example occurred when the 2018 Carr Fire spawned an EF3 fire tornado with estimated wind speeds of 143 mph! And as climate change drives increasing wildfires around the planet, it only makes sense that we see more fire tornadoes as well. But, watch to the end of this episode because even though fires are burning more acres each year we have some very good news about climate change and carbon storage of burned forests.

Caitlin and Arlo explore a material that may seem mundane and ubiquitous, but is in fact the backbone of our modern telecommunications infrastructure: silica glass. They visit the Diablo Glass School to discover how chemistry plays an important role in the material’s versatility, and experiment with manipulating glass to change its color, and make it so durable that even hammering won’t break it.
But how does this lead to the internet? To find out, they meet with the Exploratorium’s Desiré Whitmore -- also known as “LaserChick” -- who uses lasers to demonstrate how information can be transmitted through glass, and explains how that forms the basis of an ever-growing global fiber optic network than enables high speed internet communication.

Methane is a molecule that causes a bit of a conundrum: On the one hand, it’s a fuel that burns cleaner than coal or oil (it could be a bridge fuel to reach a renewable energy future, some believe). On the other hand, it’s a greenhouse gas that’s 86 times more potent than carbon dioxide, according to the Intergovernmental Panel on Climate Change. Controlling methane leaks and emissions, both climate scientists and activists say, is crucial for controlling global climate change.
Hosts Caitlin Saks and Arlo Perez Esquivel investigate this tricky molecule -- and its dancing abilities -- by tracing it to its source, both in nature and in the city.

The humble dog has been adapting and evolving alongside humanity since before we learned agriculture and how to make our own tools. This long history means #dogs are incredible at human-canine interaction but is there a downside to this all human-focused adaptation? Hosts Natalia Borrego and @TraceDominguez talk to Laurie Santos, Director of the Yale Cognition Center, to find out.
On Animal IQ we dig into the research and talk to the experts to find out just how smart animals appear to be. We then use that knowledge to fill in our AIQ Rubric across five domains of intelligence: Social, Rational, Awareness, Ecological, and our own intelligence X-Factor. Every animal is clever, but their talents v...

We know animals are intelligent, but what we don’t know is how to compare the intelligence of one animal to another. Our Animal IQ Rubric helps us measure five domains of intelligence to finally answer the question: how smart are Earth’s animals?
For generations, humans have wondered if other creatures think the way we do. Scientists devise tests, experiments, and devices to probe the cognition of our fellow fauna. Researchers use puzzle boxes, hidden cameras, brain scans, and mirror tests to suss out social skills, learning ability, vocalization, memory, and even collaboration. Yet, after centuries of study, some animals still leave us stumped. Do we have the tools to understand animal intelligence? Can we really know which anima...

It’s a mile long and 150 feet high, and covered in the most spectacular ice falls anyone has ever seen. And it’s all human-made. The Ouray Ice Park is the world’s premier location for ice climbing and attracts visitors from around the world. Nobody has ever attempted to create anything on this scale. How do they do it?
The people who make this place every winter call themselves ice farmers. They rely on a complicated system of above-ground plumbing and intimate knowledge of ice to build this frozen marvel. But even ice farmers get surprised by the behavior of ice and water. The water molecule is one of the strangest on the planet, and there’s so much more for scientists to learn about it.

Why do we see so much extreme winter weather even as the climate warms? Veteran climate scientist Judah Cohen describes one theory explaining the connection between changes in the jetstream, polar vortex events, and climate change. These bring blizzards, cold temperatures, and record-breaking snowfall to places that are expected to be warming. Examples are the Texas deep freeze in 2021 and in 2022, the extreme snow in Virginia which stranded drivers on I95 for over 24 hours. Watch to find out how global warming could be the cause of major weather shifts that actually increase snowfall events.

American prairies were once home to as many as 60 million bison. But when ranching and agriculture displaced elk and bison from the prairies, America’s grasslands all but disappeared. Now, the Nature Conservancy manages the largest remaining protected tract of tallgrass prairie in the entire world, the Joseph H. Williams Tallgrass Prairie Preserve in northeastern Oklahoma.
This 40,000-acre expanse is much more than grass. It is a biologically rich habitat that harbors a diverse collection of plant and animal species—more than 750 species of flora and 80 different mammals. This prairie is also a vital component in nature’s fight against climate change. The key to keeping the prairie healthy? Bison.
The Nature Conservancy reintroduced 300 bison to this prairie in 1993, and the herd has grown to more than ...

Landslides occur in mountainous areas all over the world. One of the most devastating in US history struck on January 9, 2018, when 1,000,000 cubic tons of mud, boulders, and uprooted trees barreled into the sleeping town of Montecito, CA, claiming 23 lives and causing around $1 billion in damage. But as shocking as this event was, it was not an anomaly. They occur in every US state, killing dozens and costing around $4 billion each year. And the hazard is growing as we increasingly build in risky areas and climate change makes triggering events, like fire and heavy rain, more common.

Vikram Baliga studies anatomy and movement of animals in the Department of Zoology at the University of British Columbia. He examines how birds use their wings to generate force and carry them through the sky. Truly understanding the mechanics requires hands-on study — so Baliga sources bird cadavers from museum collections at the Beaty Biodiversity Museum. It sounds morbid, but with a closer look, humans can learn how to build better aircraft or automobiles, using superior natural design informed by millions of years of bird evolution.

Today, they are celebrities on these islands, creating a tourist frenzy and drawing thousands of people every summer to the northern beaches of North Carolina.
But the situation is complicated. The horse population needs to be managed because they can cause serious damage to the ecosystem. How can we respect these horses and keep them wild while protecting the islands?

Though the creatures can't “say” how they feel, exactly, Bonnie uses data to translate their behavior into something we can understand and respond to. Are the giraffes happy? Do penguins get too hot? Can the sheep get a good night’s sleep? As the zoo’s animal welfare scientist, Baird answers these questions and more to help keep the animals healthy and content.
