Podcasts

Our podcasts focus on raising awareness about the science that underpins environmental issues. Topics include climate change, energy, sustainable living, agriculture, and threats to air, water, and wildlife.

From 2012-2016, we collaborated with WAMC Radio to produce Earth Wise, a daily segment broadcast twice a day.

We are now partnering with Pulse of the Planet which broadcasts on over 270 (national and international) stations.

All the salt we put on our roads in the winter has to go somewhere

Podcast

Across the Northeastern US, over 10 million tons of sodium chloride is applied to roadways annually. We also rely on salt to prevent falls on walkways and driveways. While useful for stabilizing slippery surfaces, salt use comes at a cost.

Can we capture the carbon?

Podcast

When I speak to public audiences about climate change, people often ask: Isn't there a way to capture and remove carbon dioxide from the atmosphere?

Another reason to be ticked off

Podcast

It’s time to add another tongue-tying illness to the list of maladies carried by ticks. Lyme disease is the most common tick-borne illness in the U. S., with more than 30,000 people infected annually.

How dams can cause fish declines

Podcast

The Glen Canyon Dam was the last big dam built in the United States. Spanning the Colorado River above the Grand Canyon, it provides hydropower for the region and regulates the flow of water. Until the dam was built, the river would experience spring floods during snowmelt followed by low flow in the summer, especially during drought years. Now water below the dam flows at about the same rate year-round.

Cities as ecosystems?

Podcast

Ecologists define an ecosystem as a unit of the landscape—a forest, a lake, or a river.  Often, they are interested in the movement of materials through that area.  Rain may deposit nitrogen in a forest, while a stream may carry nitrogen away from the forest and into a river.

In praise of big old trees

Podcast

Nothing is more beautiful than a tall, stately tree. But sometimes they get in the way of progress. Well-meaning people think that planting a couple of smaller trees will make up for the loss of the elder statesman. Not so.

A tiny invader that's driving people indoors

Podcast

The Asian tiger mosquito is yet another invasive species that has taken hold in the United States. It arrived here in 1985 in a shipment of tires imported from Asia.  This little mosquito is an aggressive human biter capable of transmitting diseases.

Why should we care about one endangered fish?

Podcast

The humpback chub is a rather homely fish that lives only in the Colorado River. It is federally listed as protected under the Endangered Species Act.

We all know about rain forests. Now we are learning about fog forests

Podcast

There's a desert in north-central Chile that receives less than six inches of rain a year. Right in the middle of it is a lush mountain forest that is dense with trees, bromeliads, ferns, and mosses.

When good ideas produce bad outcomes

Podcast

When rainwater passes over hard surfaces, like roads and parking lots, it accumulates pollutants, which are then washed into nearby waterways.

Improving water, improving lives

Podcast

Add water pollution to the list of ills suffered by under-served urban communities. Economically-depressed neighborhoods are hotspots for water contamination due to aging sewer and storm-water systems. Optimistically, a new study suggests that water cleaning and community greening can go hand-in-hand. 

Let's not put the last log on the fire

Podcast

In an attempt to wean the nation from coal—an unhealthy source of energy that drives global warming, several policy groups have suggested switching to wood. Existing coal-fired power plants could be converted to burn wood with relatively little cost and expense. And trees have the benefit of being a renewable resource.

Science, art, and music-all in the same room

Podcast

The Cary Institute of Ecosystem Studies is a scientific research and education organization. Sixteen Ph.D. scientists explore pressing environmental problems including acid rain, forest health, the ecology of Lyme disease, and pharmaceuticals in our waterways.

Trees are good for human health

Podcast

Many of us have experienced a restorative walk in the woods. But does associating with trees really make us any healthier? 

The future of woodland pools

Podcast

Woodland pools are temporary wetlands that provide important habitat to forest wildlife. They also help mitigate floods. While land development is a major threat to woodland pools, there are also subtle changes that undermine their health.

Rethinking wild boars

Podcast

Wild boars are a problem in more than twenty states. These invasive animals are prolific breeders with voracious appetites. They cause tremendous damage to crops and native plant communities and they spread diseases, such as pseudorabies, from feral hogs to domestic livestock.

The dirty truth about unpaved roads

Podcast

In rural areas, unpaved roads hold a certain charm. They restrict the volume and speed of traffic and, compared to their paved counterparts, are less expensive to build. But are they a greener alternative?

Pharmaceuticals disrupt sensitive stream habitat

Podcast

Pharmaceutical pollution is found in waters throughout the world. Causes include sewage overflows, aging infrastructure, and agricultural runoff. Even when waste water makes it to sewage treatment facilities, they aren't equipped to remove most pharmaceuticals.

Frankenbug?

Podcast

There are few creatures more deadly than the tiny Aedes aegypti mosquito, which transmits malaria, dengue fever and other infectious diseases.  Malaria is one of the world’s great killers, claiming about 800,000 lives each year.  We can, of course, drain wetlands and spray large areas with insecticides to kill these mosquitoes.

Mosquitoes in urban areas

Podcast

Now that summer is finally on the horizon, so too is mosquito season. More than an annoyance, mosquitoes can spread serious illnesses, like West Nile virus and Dengue.
