To adapt to rising sea levels, coastal wetlands can migrate landward at the expense of adjacent freshwater wetlands and upland ecosystems, but migration can be hindered by natural and anthropogenic barriers. This photo shows marsh migration constrained by topographic and urban barriers in southern California.

The Caldor Fire in California started on August 14, 2021 and quickly spread in high winds. The fire expanded toward the Lake Tahoe area as residents evacuated. Landsat image was captured on August 21, the 8th day. Landsat 8's near-infrared and shortwave infrared bands reveal active fire, burn scars, and smoke.

10-YEAR ANNIVERSARY OF THE M5.8 EARTHQUAKE IN VIRGINIA
America’s Most Widely Felt Earthquake

Dixie Fire The Dixie Fire has become the largest single fire in California's recorded history. State fire officials don't list it at the top, however. The record is held by the massive August Complex Fire of 2020 which burned over one million acres. The term "complex" is used when multiple fires in the same area ignite separately.

U.S. Geological Survey research hydrologist Austin Baldwin collects a soil sample near Meadow Creek, Washington, for mercury analysis. Baldwin and USGS colleagues conducted a study of mercury mobilization, methylation, and bioaccumulation in aquatic insects in headwater streams of the Pacific Northwest burned by wildfire.
