The carbon cycle is a process where carbon dioxide travels from the atmosphere into living organisms and the Earth, then back into the atmosphere. Learn how changes in carbon dioxide levels, such as burning fossil fuels (oil, gas, etc.), affect the atmosphere and the ocean. We will flood a "bathroom" and see why it's a good thing to shut off the water and or make the Earth's atmosphere "drain" bigger so we don't mess up our home. (45 mins)

Excess carbon dioxide (CO2) isn’t just warming the planet; it’s also reacting with seawater and making the oceans more corrosive—a process known as ocean acidification. This slight increase in acidity doesn’t change the way the ocean looks or feels to us—but it’s a big deal for marine species with hard parts made of calcium carbonate, like pteropods, whose delicate shells begin to dissolve when exposed to acidified seawater. Meg Chadsey will demonstrate how ocean acidification is stressing her favorite local shellfish species—oysters—and explain why some shellfish farmers are turning to kelp for help. (45 min)

Fire weather is a combination of conditions that set the stage for the rapid spread of wildfires. Join us to meet one of NOAA's incident meteorologists who helps keep fire crews safe by enabling responders to plan operations around one of the most variable aspects of any incident — the weather. Kari is a National Weather Service forecaster who has been specially trained and certified to provide weather support at a fire location. (45 min)
