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

Let's talk about ammonia

Podcast

Most of us are familiar with ammonia as an irritating gas that is emitted from window-cleaning fluids. It is a great way to cut through grease that has condensed on glass.

Science and art

Podcast

Science and art are rarely thought of as going hand-in-hand. In fact, we typically think of scientists and artists as having entirely different type of brains – one logical and analytical, the other creative and subjective.

Bad news for maple syrup and moose

Podcast

Following an exhaustive review of more than fifty years of long term data on environmental conditions at the Hubbard Brook Experimental Forest in the White Mountains of New Hampshire, the results are clear: spring is advancing and fall is retreating.

When antibacterials go down the drain

Podcast

Around half of liquid soaps now contain the chemical triclosan, as do toothpastes, deodorants, cosmetics, and other personal care products.

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.
