As factories shut down and fewer people drive to work, the environment is getting cleaner. Carbon emissions have dropped worldwide and people around the globe are noticing clearer air and better views of mountains. Scientists point out that an even bigger drop is needed to head off the worst effects of climate change, requiring actions such as converting to wind and solar power. Listen to hear more about how the slowdown in human activity is affecting the environment and why scientists believe animal sightings have increased.

The earth is getting warmer. Records kept for the past century show a steady increase in temperature each decade, and 2019 was the second hottest year ever. As humans send carbon dioxide into the air from cars, factories, and other sources, the trapped heat warms the planet, causing glacial ice to melt, oceans to rise, and big weather events like floods and droughts to increase in intensity. Listen to learn more about changes to the earth caused by global warming and what to expect in the future.
Current Event January 14, 2020
Wildfires are raging in Australia, threatening human and animal life. As the climate warms and rainfall and humidity decrease, large parts of the land have become dry and brittle – ideal conditions for fires to start suddenly and spread quickly. Listen to hear how intense heat and smoke are affecting daily life and what residents are doing to stay cool when temperatures reach 120 degrees Fahrenheit.

Renewable resources are said to provide “clean” energy that does not harm the planet. Some say wood is renewable, arguing that trees can be replanted, and that the carbon dioxide released by burning wood is eventually reabsorbed by the new trees, making them “carbon neutral.” Others dispute the math used to calculate carbon neutrality since it takes so many years to regrow a forest. Listen to hear why the U.S. is sending millions of tons of wood pellets to Europe for burning and then debate: Should wood be considered renewable energy?
A variety of adaptations help animals survive the winter, when temperatures drop and food is scarce. Some migrate, some change how they eat and find ways to stay warm, and some hibernate, essentially going to sleep for many months. Listen to learn about how different animals adapt to the changing seasons and find out what happens when bears hibernate.

A Chinese insect has invaded Pennsylvania. It likely traveled on shipping containers across the Pacific ocean and when it arrived, it found bountiful food and no real predators. Now, the spotted lanternfly populations are getting out of control. With both ecosystems and businesses suffering, experts are considering drastic actions to reduce this invasive insect’s spread. Listen to learn more about the spotted lanternfly and scientists’ “crazy” solution to this bug’s growing numbers.

Current Event October 16, 2019
Low-income urban neighborhoods are often hotter than wealthier neighborhoods in the same city. This is problematic, especially during heat waves, when residents’ health and even their lives could be at risk. One of the reasons poorer areas get hotter is because they tend to have fewer trees. Listen to learn how trees keep communities cool and why they are more prevalent in some neighborhoods than others.
Current Event October 2, 2019
