Global temperatures are rising, putting bird species across America in danger of extinction as their habitats change. To understand how temperature affects birds across the country, scientists at the University of Wisconsin-Madison compared data from the thermal sensor on Landsat 8, TIRS, to bird biodiversity across the country.
Turns out, having a habitat with pockets of different temperatures – like a grove of trees in an open field, or a nest or snow burrow – is especially important for small-bodied bird species and those threatened by climate change.
This bird’s-eye view of the relationship between temperature and bird biodiversity will help conservationists figure out where to prioritize their efforts in a warming world.
The Landsat Program is a series of Earth-observing satellite missions jointly managed by NASA and the U.S. Geological Survey (USGS). Landsat satellites have been consistently gathering data about our planet since 1972. They continue to improve and expand this unparalleled record of Earth’s changing landscapes for the benefit of all.

Data as Good as it Gets: A Discussion with Brian Markham
March 20, 2025
Why do we calibrate Landsat data? We spoke with Brian Markham, a key figure of Landsat calibration science for four decades. He said that it all comes down to this: “If we’re using a system to quantify changes on the Earth, we must make sure the system we’re using is not changing.”
