What does a geoscientist do? Yes, Earth and space scientists work at lab benches, but they also design experimental plots, explore exoplanets and ocean depths, and use supercomputers and Secchi disks.

Researchers used paleoclimate data, modeling, and measurements of sea surface temperature to learn more about future climate. They used the Western Pacific Warm Pool, seen here in 2016, as a reference ...
