Reconstructing Climate History - How Do We Know?

The video explores how scientists use natural archives, known as proxies, like tree rings, corals, and ice cores, to study past climates. It highlights the importance of understanding interglacial periods and how sediments and corals provide valuable climate data. The process of ice core analysis is explained, showing how it helps reconstruct past climates. Despite uncertainties in proxy data, the video concludes that modern warming is unprecedented in the last thousand years.
