In this Aug. 29, 2021, satellite image provided by Maxar Technologies shows an overview of the Caldor Fire near South Lake Tahoe, Calif. The Caldor Fire has scorched nearly 277 square miles (717 square kilometers) since breaking out Aug. 14. After the weekend's fierce burning, containment dropped from 19% to 14%. More than 600 structures have been destroyed, and at least 20,000 more were threatened. Climate change has made the region warmer and drier in the past 30 years and will continue to make the weather more extreme and wildfires more destructive, according to scientists.
