20 Observations That Help Scientists Study Climate History
Scientists reconstruct Earth’s climate history by analyzing physical, chemical, and biological "proxies" that preserve atmospheric and environmental data from the distant past.

Scientists reconstruct Earth’s climate history by analyzing physical, chemical, and biological "proxies" that preserve atmospheric and environmental data from the distant past.

Early scientific findings replaced long-held ideas by showing that careful observation could reveal patterns hidden from everyday experience.

Certain scientific observations have sparked entirely new fields of study, transforming the way humans understand the natural world. These breakthroughs often began with a single insight that inspired decades of research and innovation.
