The fires in Greece during the summer of 2007 devastated large tracks of forest and ground cover in this Mediterranean region. These before (left) and after (right) images were taken on July 18 and September 4 by Landsat-7. The red areas show the extent of the biomass loss from the fires.
On June 27, 2018, an illegal campfire caused the third-largest wildfire in Colorado state history, known as the Spring Creek Fire.
Fire is a powerful force on our planet. From South America's rainforests to Africa's savannas and Australia's highlands, fires touch 30 percent of the land surface. Yet whether naturally occurring or set by humans, fires' effects reach far beyond ravaged lands.
Lately, it feels like we’re hearing about wildfires erupting in the western United States more often. But how have wildfire occurrences changed over the decades?

Carbon dioxide concentration in the atmosphere is affected, among other things, by processes involving forests including fires, deforestation and plant respiration. Evaluate a Landsat image to determine the rate of carbon dioxide sequestration in a particular area.
Forests are an important and common feature of the Earth’s land cover, covering 31 percent of the total land surface. There are two regions in particular where forests are common.
The purpose of this activity is to have students use an Earth Systems perspective to identify the various causes associated with changes to Earth's forests as they review Landsat imagery of site locations from around the world.
Please consider using this graphic organizer to help students analyze the processes and components of Earth System phenomena.
Using the technology inside your phone (or tablets), students can help scientists classify land cover and track changes.
