temperature reconstructions

Temperature reconstructions are scientific methods used to estimate past climates by analyzing natural evidence like tree rings, ice cores, sediment layers, and fossils. These sources contain clues about historical temperatures, allowing researchers to create timelines of how climate has changed over centuries or millennia. By studying these records, scientists can better understand natural climate variability, identify long-term trends, and compare past climates to current ones. This helps inform predictions about future climate changes and understand the Earth's climate system in a broader context.
