To track the rate at which glaciers are shrinking, scientists take GPS data points at the end, or terminus, of the glacier. Grinnell Glacier is one of 26 glaciers, out of a recorded 150, remaining at Glacier National Park, Montana.

Climate science encompasses atmospheric science, physical geography, oceanography, and biogeochemistry. It examines many factors to better understand current weather patterns and make future projections. Climate science looks at the big picture, meaning the sum of changes across Earth, rather than using one place to speak for all. It tells us how the climate is changing, why, and what it means for life on Earth.
