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.

The Arctic may seem like an unlikely place for fires, but every year wildfires burn millions of acres of forest in Alaska, northern Canada, and Siberia. This century, the blazes have grown bigger, hotter, and more frequent, causing health problems for local residents and releasing harmful greenhouse gases into the environment. Listen to hear a climate scientist describe the effects of wildfires in the Arctic and how the global community can respond.
Current Event September 9, 2019
Fires are raging in the Amazon rainforest at an unusually high rate. The flames are destroying hundreds of acres of forest, killing wildlife, and spreading smoke across thousands of miles. Scientists are concerned that, since trees take in carbon dioxide from the air, the loss of so much forest could speed up climate change. Some environmentalists argue that this is a man-made disaster, caused by intentional deforestation. Listen to learn more about the enormous scale of the fires burning in the Amazon rainforest and the ongoing debate about who is responsible.

About 250 million years ago, there was a widespread extinction on earth. Scientific investigations into the climate conditions leading to this prehistoric “Great Dying” can shed light on how climate change in the modern world might impact life on the planet. The “Deep Time” exhibit at the Smithsonian National Museum of Natural History explores the state of the earth and its inhabitants in that era. Listen to hear about how the “Great Dying” happened and why it is relevant today.
Current Event June 12, 2019
Students around the world have been skipping school to protest their governments’ lack of action on climate change. Now, this movement has come to the United States. American students are gathering together to demand that Congress take action to protect them from the effects of climate change. Listen to find out more about what students are asking of their government leaders and why.
Current Event May 22, 2019
A new natural disaster lab uses extreme methods to test which building materials are safest to withstand major storms and wildfires. Listen to find out why insurance companies want to invest millions of dollars in this lab and why climate change makes the lab’s experiments more important than ever before.

Scientists from the Desert Research Institute in California are recruiting some very young researchers to help them better understand snow storms. The researchers have opened up data collection to citizen scientists, as they will need many snowflake pictures to answer their questions. The 4th and 5th grade students participating in the “Stories in the Snow” project are learning how to take very detailed pictures of snowflakes. Listen to this story to hear more about what the scientists hope to learn from their snow research, what students are learning from participating, and who will benefit.

A new government report on climate change warns of the rapidly increasing negative effects of climate change and offers recommendations to help slow down its adverse impact. The report explains that not only are humans responsible for climate change, but our ongoing actions are making it worse. Listen to this interview with a climate change expert to hear about the urgency of this warning and what makes her hopeful.
Current Event October 24, 2018
A recent report by a United Nations panel indicates that if we do not take action immediately to lessen the impact of global climate change, the negative consequences will be severe. A professor who worked on the report explains that global warming is already influencing our lives and the ecosystems that surround us. Listen to hear more about the rapid pace of climate change and what we can do to decrease the potential for disaster associated with it.

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.

Earth’s largest living organism, the Great Barrier Reef, has had record losses of coral in the last few years. A team of scientists estimate that an average of one-third of the corals along the entire Great Barrier Reef died between March and November of 2016. The global rise in greenhouse gas emissions has made ocean temperatures rise and has contributed to the number of coral that is dying, which is devastating for thousands of species that depend on the reef. Listen to hear more details about the loss of coral and the causes.

President Donald Trump pulled the United States out of the Paris Climate Accord. The accord is an international agreement signed by more than 190 countries who have agreed to address climate change by trying to keep global temperature rise this century below 2 degrees. Trump says that the Paris Agreement would have been bad for U.S. workers and their businesses. The U.S. produces the second highest greenhouse gas emissions and is only topped by China, who remains committed to the agreement. Listen to learn more why Trump decided to leave the agreement and what it might mean for the future.

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.
