About this Research Topic
Continental climate variability during the Holocene Epoch is important for all aspects of civilization and society development, not only because human civilization was developed on the continents, but also because of the highly heterogenous patterns of continental climate change. There are many unresolved questions for the Holocene temperature change. For example, it remains controversial how temperature changed during the Holocene as there exists discrepancy between temperature reconstructions and climate modelling results, which is called the Holocene temperature conundrum.
The temperature conundrum likely results from the seasonal biases in temperature reconstructions, and potentially unexplained uncertainties in the climate models. Various proxies have been adopted for quantitative temperature reconstructions, including pollen, alkenone, GDGTs, chironomidae, etc. Each proxy has its inherent response to temperature, which makes the reconstructed temperature records may capture different seasonality. Furthermore, transfer functions for a specific proxy vary significantly in different regions, which likely bring unexpected uncertainties during temperature synthesis. Recent developments of new proxies, such as di-ols, clumped isotopes, will bring more opportunities to quantitative temperature reconstructions.
Furthermore, it has been reported that high latitude temperature variability is more evident than low latitudes, however, there is a lack to assess the altitude effect on the temperature variability. More quantitative temperature records based on various proxies across the world’s continents are essentially required to understand global patterns of Holocene temperature variation.
In this Research Topic, we welcome quantitative temperature records based on various proxies in continents to understand the temperature variability around the world. We welcome quantitative Holocene temperature reconstructions from continental archives (lake, peat, speleothem, ice core etc) using various proxies, including biomarkers, pollen, midge, isotopes, with well-defined temperature implications. The records should have good chronological controls, with decadal- to centennial- scale resolution. We also welcome updated calibrations for various proxies in different regions.
