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.

Selected Podcasts

Salty streams and rivers

Podcast

By the looks of it, we're in for quite a winter this year. Here in the Northeast, we've seen several heavy snowfalls, freezing temperatures, and icy roads.

Summertime ozone

Podcast

Human activities are not direct sources of a lot of ozone, but ozone concentrations increase to markedly unhealthy levels in many areas during the summer. About 30 years ago, atmospheric chemists solved this mystery.

Here's the fish, and here are the fish on drugs

Podcast

We are a nation of pill poppers. From statins to lower cholesterol to antidepressants to lift our mood, more than half of Americans are currently taking a prescription drug. Some twenty percent of us are taking three different prescriptions daily.

The many benefits of urban trees

Podcast

Trees increase property values in neighborhoods where they are planted. Through the evaporation of soil water, trees cool the urban environment, reducing the need for air conditioning.

Invaders underfoot in our forests

Podcast

Despite their familiarity, earthworms are an invasive species in America's northern temperate forests. They arrived in the mid-1800s, with the arrival of European settlers.

Keeping a pulse on the Hudson River

Podcast

Technology has transformed our ability to understand rivers. Take the Cary Institute's longstanding scientific program on the Hudson River. 

Few ecosystems on our planet are as mysterious and misunderstood as groundwater

Podcast

Despite the fact many of us drink groundwater every day, and all of us eat food irrigated by groundwater, few people know where it comes from or how to protect it.

Hydroelectric dams and carbon sequestration

Podcast

One of the key ways of mitigating climate change is to keep carbon away from the atmosphere where it is found as carbon dioxide, a key greenhouse gas. Carbon that is stored in trees and other woody plants, in soils, and in the oceans is said to be sequestered.

A mosquito fever expands its range

Podcast

A mosquito-borne virus that causes fever, headaches, and severe joint pain has spread to the Caribbean. Experts fear it's only a matter of time before it makes its way to the U.S. 

Road Salt

Podcast

In the U.S. alone, some 15 million tons of salt is applied to roadways each year. While its use has real benefits, in terms of safety and navigation, there have been cumulative costs to the environment.

Ecological engineering on the ski slope

Podcast

Every winter, ski resorts groom trails using heavy machines that do a great job flattening the snow, but also compact the soil underneath. In the offseason, the compacted soil makes it hard for vegetation to regrow, so a lot of money is invested in re-vegetation.

earthworms

Earthworms are invading our forests

Podcast

In the northeastern U.S., all earthworms are non-native. And they are damaging our forest habitats.

Hard or soft? When engineering shorelines, it makes a big difference

Podcast

Most of us have experienced a river shoreline— from a park, a train, or a boat. When we see where the water meets the land, how many of us have considered how modified shorelines influence river health?

The hidden cost of antibacterial products

Podcast

Triclosan, a synthetic antibacterial used in personal care products, is fueling the growth of resistant bacteria in streams and rivers.

Dirty drinking water

Podcast

EPA and U.S. Geological Survey scientists analyzed treated water samples from 25 U.S. utilities. They found that more than 1/3 contained chemicals not regulated by the federal Safe Drinking Water Act.

Dust in the wind

Podcast

Increasingly, atmospheric chemists are understanding the importance of dust particles—known as aerosols—in our atmosphere. Many aerosols are rather large particles that fall out of the atmosphere fairly quickly.

Are fish made of maple leaves?

Podcast

Most of us learned about the aquatic food web in high school. Using a sealed aquarium, teachers explained that plants form the base of the web, with the organic carbon they create supporting aquatic life—from invertebrates to sport fish.

More wildlife diseases are making the leap to humans

Podcast

Research has found that when humans modify the environment, fragmenting habitat and reducing species diversity, we are more likely to contract diseases normally confined to wildlife.

Dams complicate river management

Podcast

Managing fish in human-altered rivers is a challenge because their food webs are sensitive to environmental disturbances.

What's all the talk about mute swans?

Podcast

In the late 1800s, mute swans were brought from Europe to the eastern U.S. to enhance the beauty of ponds on private estates.

deer

Have deer gotten a false rap for Lyme disease?

Podcast

It's commonly believed that Lyme disease risk is tied to the presence of deer ticks and white-tailed deer. But this simply isn't correct.
