More than 100 podcasts（播客）this year in NPR's Student Podcast Challenge have touched on a topic that's increasingly important to young people: climate change. Here are four student podcasts that show the minds of students and what they have to say about climate-related news in their communities—and what they hope to do about it.

At Chautauqua Elementary, the Vashon fifth-graders talk about the far-reaching and lasting impact of wildfires and wildfire smoke—and the direct effects on their lives, like waiting for the school bus on a smoky day. The students also interview experts and share their research on wildfire precautions（防范）.
Flowing Through Time In this podcast from Peak Academy, a group of eight middle schoolers reports on dealing with water shortages in Bozeman, Montana. They track the history of their growing hometown's water supply, which has been dependent on mountain snowmelt. As that sourcebecomes less reliable in a warming world, the students turn to the grown-ups to ask what they can do to conserve water.
