An overview of paleoclimate information from high-resolution lake sediment records: Strengths, limitations and key databases
Years of record
- N/A
Accumulated sediments at the bottom of lakes are invaluable archives of past climate and environmental change. These sediments contain a variety of physical, geochemical, and biological proxy indicators that can be used to gain a multi-faceted understanding of past conditions. Unlike other high-resolution paleoclimate archives, such as tree rings, corals, and speleothems…

Coral geochemical records: An overview of their use as climate proxies and of available databases
Years of record
- N/A
Coral records are one of the main types of high-resolution (annual to sub-annual) paleoclimate proxies, providing timeseries of environmental conditions reaching hundreds to thousands of years into the past in the tropics, the central driver of the global atmospheric circulation. As such, corals complement paleoclimate records from the largely mid-latitude tree-…

Drought atlases from tree rings
Years of record
- to
Tree-ring drought atlases provide a paleoclimate analog to modern drought indices, most commonly the Palmer Drought Severity Index (PDSI). Produced on a regular lat-lon grid for regions such as North America, Europe, and Australia, these centuries-long datasets are convenient for comparisons with climate model experiments and historical data on human populations…

Speleothems and the SISAL database: An overview of the use of speleothems as archives of climate proxies
Years of record
- N/A
Speleothems provide globally distributed, seasonal to multi-annual resolution climate records encoded in multiple proxies including oxygen and carbon stable isotopes, and trace elements. Speleothems, such as stalagmites and flowstones, are secondary cave carbonate deposits. They grow by incremental deposition of layers of calcium carbonate from dripping water, and encode…

Tree-ring width chronologies: An overview of their use as climate proxies and of available databases
Years of record
- N/A
The width of an annual tree ring is a very simple indicator of the character of that year’s weather, but collectively the global network of tree-ring width measurements represents an invaluable resource for high-resolution paleoclimatology.
