In 2021, Hurricane Ida left over 1 million people without power, tornadoes tore across the American Midwest, volcanoes forced people to evacuate their homes, wildfires covered the American West and unusual flooding wreaked havoc on Central Europe.
Some characteristics of natural hazards, such as
hurricanes, floods and wildfires, have been historically predictable and have
informed disaster preparation. However, with human emissions of greenhouse
gases increasing Earth's temperature, we're seeing changes in those
characteristics: wildfire and drought seasons are lengthening, hurricanes and
rainfall are becoming more intense, and coastal flooding is increasing.
By sponsoring application science and fostering
domestic and international partnerships, the NASA Disasters program seeks to
use its Earth observation data to enable disaster-resilient communities in a
changing climate.

NASA Disasters program supports risk reduction, response and recovery, go to Remembering 2021's Disasters.
This day/night-band
imagery of Hurricane Ida was captured by the VIIRS instrument onboard
the NASA/NOAA Suomi-NPP satellite early the morning of Aug. 30, 2021.
Day/night-band imagery is useful for identifying nighttime lights from cities
and can be used to monitor for loss of light which may indicate power outages
in the wake of a disaster. Credits: NASA
