What methods do scientists use to reconstruct both long-term and shorter term climate histories?
What will be an ideal response?
The primary methods for long-term reconstructions include ice core and ocean sediment analysis. Both are based on measuring isotopic ratios. For shorter-term reconstructions, methods such as dendrochronology (dendroclimatology), lake core sediments, pollen analysis, speleothems analysis, and coral analysis. Some of these methods will use radiocarbon dating techniques.
