Fires burned across California in late 2019. Fall is the state's most dangerous season for wildfires, propelled by dry and windy conditions. In recent years however, the fall fire season has been starting earlier and ending later. A series of images from the MODIS sensor on NASA's Terra and Aqua satellites show the Kincade Fire in northern California.

The degradation of coastal habitats, particularly coral reefs, raises risks by increasing the exposure of coastal communities to flooding hazards during storms. The protective services of these natural defenses are not assessed in the same rigorous economic terms as artificial defenses, such as seawalls, and therefore often are not considered in decision-making.

Low-lying island environments are particularly vulnerable to impacts from coastal hazards, including inundation (coastal flooding), whether the increased water levels are from episodic events (storm surge, wave run-up, king tides) or from chronic conditions (long term sea-level rise).

USGS Hawaiian Volcano Observatory scientists Frank Younger and Patricia Nadeau talk about sampling the water at the bottom of Halemaʻumaʻu, a crater at the summit of Kīlauea Volcano. The water appeared in July 2019 and has steadily risen since then.

Wildfires burned across Lebanon in mid-October, 2019. A pair of images taken just ten days apart by the European Space Agency's Sentinel-2A satellite show the burn scar from one of the larger wildfires. North of the fire scar is the country's capital, Beirut.

In this video, you can hear the honks and quacks of geese and ducks ring through the air, as birds fly in every direction above a wetland. This video was captured at Sacramento National Wildlife Refuge in November 2019, not long after geese and ducks began to arrive to spend the winter in the California Central Valley.

This video shows the proper technique for collecting a skin swab from a bat that is either roosting in place or is manually restrained for white-nose syndrome surveillance.

Environmental samples collected in or near bat roosting locations can be used to supplement samples collected from bats for surveillance for white-nose syndrome (WNS) (https://www.usgs.gov/centers/nwhc/science/white-nose-syndrome).
