Today, you will be taking your last GLOBE measurements – measuring the amount of tropospheric ozone in the air, the type of cloud cover, the surface and air temperature, wind direction, and humidity.
We are going to learn about global warming, which occurs when Earth’s climate becomes warmer. Certain gases in the atmosphere, like carbon dioxide, are called greenhouse gases because they trap in Earth’s warmth. Without them, most of Earth’s surface would be frozen. However, emitting more of these gases to the atmosphere can contribute to global warming. You will learn about some of the possible impacts of global warming today.
Energy efficiency and alternative sources of energy can help reduce emissions of greenhouse gases. For example if cars can use gasoline more efficiently, less air pollutants and greenhouse gases will be released into the air.
You will also be able to calculate your “carbon footprint.” A carbon footprint tells you how much carbon dioxide is emitted as a result of your day‐to‐day actions. It can also tell you how you could change your actions so that fewer pollutants are released into the air.
