Paleoclimate reconstruction techniques

WebGlobal warming has occurred. Multiple paleoclimatic studies indicate that recent years are all the warmest, on a global basis, of at least the last 2,000 years. The most recent paleoclimate data reinforce this conclusion using longer records, new proxies, new statistical techniques, and a broader geographic distribution. There are several types of sources where paleoclimate researchers can find preserved records of past climates. 1. Glaciers and Ice Sheets: Long-term bodies of ice, such as the Greenland and Antarctic ice sheets, have annual cycles which build new layers of ice each year like tree rings. Layers in the ice … See more The data that are collected and interpreted by paleoclimatologists are known as proxies, stand-ins for what can't be directly measured. We can't travel back in time to measure the … See more Proxy evidence can be biotic, geomorphic, geochemical, or geophysical; they can record environmental data that range in time from yearly, every ten years, every century, every millennium or even multi-millennia.
