Permafrost is frozen soil that has preserved things such as ancient animal bones and centuries-old icebergs. Permafrost contains twice as much carbon as is currently in Earth's atmosphere and it also preserves old bacteria. When it's defrosted the bacteria eats dead plants and animals turning their carbon into gases such as carbon dioxide. As the permafrost warms, the microbes are releasing gases contributing to further warming. Listen to learn more about this warming cycle.

The Santa Ana winds are making it extremely difficult for firefighters to control the range of the wildfires in Southern California. The fires have burned more than 272,000 acres and destroyed more than 1,000 homes. These wildfires have caused many scientists to revisit the discussions over climate change as the United State’s western coast has continuously been battling floods, earthquakes, and wildfires throughout the entire year. Listen to hear what these fires indicate for future weather patterns.
Current Event October 23, 2017
About a month after Hurricane Maria, almost 90% of Puerto Rico is without power and many residents have become dependent on generators. Hospitals, restaurants, air traffic control towers and other businesses are now operating with generator power.

After Hurricane Harvey in Texas, many people evacuated their homes and are now living in shelters. Leaving home during an emergency was especially difficult for parents of small children. Even though they brought supplies when they left their homes, an essential item that runs out quickly is diapers. Toddlers need 6-8 every day, and infants need twice as many. Listen to hear more about how this issue is affecting families and how it is being solved.
Current Event October 2, 2017
Hurricane Maria landed directly on Puerto Rico, taking down trees and destroying homes. The hurricane seriously damaged the island’s infrastructure creating widespread power outages and damage to cell towers. People are also facing shortages of gas, food, and water. A few people have gas powered generators that are running, but most are in the dark with no way to contact friends and relatives. Listen to this story to learn more about Hurricane Maria’s effect on the people of Puerto Rico.
Current Event September 28, 2017
Houston, Texas is recovering from Hurricane Harvey and students were delayed in going back to school. Many students are staying in shelters and teachers are volunteering to provide learning opportunities to children who were traumatized or displaced by the hurricane. One special education teacher created a group of educators called Teachers Volunteering in Shelters to help these students. Listen to hear more about these volunteers.
Current Event September 22, 2017
In neighborhoods in and near Houston, Texas, many people stranded by the flooding brought on by Hurricane Harvey were not able to get through to 911. That's when social media sites such as Facebook, Nextdoor and Twitter became important connectors for people to ask for help. Some think these are effective when calls to emergency personnel don’t go through, and others encourage people to stick to 911 instead of social media. Listen to this story and then debate: Social media or 911: Who do you ask for help?
Current Event September 18, 2017
Hurricane Harvey was enormous and Hurricane Irma had record high winds of 185 miles per hour. This is very unusual, but not unprecedented. What’s unusual is that they both hit land. Global warming creates more heat, and the more heat you have, the bigger the storms. Listen to hear about the relationship between big storms and climate change.
Current Event September 4, 2017
Many parts of Texas were hit hard by Hurricane Harvey, the most powerful storm to strike Texas in more than half a century. The coastal tourist town of Rockport was hit directly. About half of the residents evacuated and rescue was difficult because of high winds, failed cell phone towers, and flooding. Listen to hear what this powerful hurricane was like from people who experienced it firsthand.

The phrase “no two snowflakes are alike” is actually scientifically accurate. Snow forms high in the atmosphere, and despite its uniform appearance, each snowflake is different based upon where and how it was formed. Although snowflakes are non-living, they grow and change from the time they are formed to the time they reach the ground. Listen to learn how snow is formed and why it exists in some places but not others.

Hurricane Sandy was a unique storm for a variety of reasons. Named a “Frankenstorm” by many due to its problematic combination of factors, analyzing this event can teach us a lot about how hurricanes work. A professor of atmospheric science explains why Hurricane Sandy was poised to be a particularly dangerous, rare blend of an “extratropical storm” and a tropical storm. He explains how a hurricane’s winds, pressure, movement, timing, and temperature all play roles in how hard it hits coastal and urban communities. Listen to learn what made Hurricane Sandy especially powerful and what it shows us about Earth’s atmosphere.

Resuming civilian life can be difficult for military veterans. Disaster relief volunteer groups like Team Rubicon allow veterans to use their specialized skills and work in cooperative teams while helping those suffering from the aftermath of natural catastrophes. Team Rubicon sent hundreds of volunteers in 2012, when superstorm Hurricane Sandy hit the East coast of the United States. Natural disaster victims are grateful to benefit from veterans’ expert assistance. Likewise, veterans enjoy the sense of purpose and community this work gives them. Listen to hear veterans’ stories of volunteering during Hurricane Sandy.

Although the United States has cut its emissions of smog-forming pollutants by half over the past few decades, smog levels in the Western United States have increased each year. Now, scientists believe that rising emissions in Asia are causing smog in the United States. Asian emissions have tripled over the past decades and are particularly high in China and India. During the spring, storms lift and carry emissions from Asia to the Western United States, causing fog. Listen to learn more about how emissions levels in different parts of the world are changing and how global climate systems move emissions around the Earth and then debate: How can we address global pollution?

Our bodies react differently to extreme heat depending on how much humidity is in the air. Heat index is a measure of how hot it feels outside, taking into account both air temperature and relative humidity. As the humidity rises, the heat index rises. In dry heat, our sweat quickly evaporates, which helps lower our internal temperature; but on a humid day, our sweat cannot fully evaporate as the air is already damp, and this prevents us from effectively cooling off. It also raises our risk of heat stroke and even death. To illustrate the science, this podcast considers the case of a man who was lost for three weeks in a remote desert in southern Utah and survived. Listen to hear more about dry versus wet heat and how it affects the human body.
Current Event February 2, 2017
California has been in a severe drought since 2014. It’s underground aquifers, which are permeable rocks that can hold groundwater are dry. During recent droughts, farmers pumped groundwater to irrigate their crops, which dropped the water table and drained the aquifers. In the Sierra Nevada Mountains, they are also getting less snow and more rain, which just runs into the ocean. Farmers are now experimenting with water management and ways to store excess water. With some recent heavy rains, rivers all over the state flooded and some farmers flooded their fields, letting the water seep deep into the ground to refill the aquifers. Listen to hear about ways to catch and store rainfall to help farmers.
