We reconstructed the vegetation and climate change since the last 14.2 ka BP from a fossil pollen record together with multiple proxies (grain size, contents of total organic carbon and total nitrogen) on the northeast Tibetan Plateau. The results reveal that an arid climate occurs in the early Holocene and the vegetation could be disturbed by human activities to some extent after ca. 0.24 ka BP (1710 CE).

Short summary
Branched GDGTs are bacterial lipids preserved in soils and sediments, used as climate proxies. This study presents the Arid Central Asian brGDGT surface database to assess their reliability in drylands. Results show that salinity, sample type, pH, and aridity strongly influence brGDGT signals, limiting temperature reconstructions. Refined calibrations improve reconstruction accuracy, and methylation index differences may indicate aridity variations.

Short summary
We completed a modern pollen dataset obtained from 90 lakes from the Tibetan Plateau (TP), and integrated it with previous modern lacustrine pollen datasets. The comprehensive modern pollen dataset covers the full range of climatic gradients across the TP and all vegetation types. The modern pollen dataset has good predictive power in estimating net primary production and annual precipitation.

We present global megabiome dynamics and distributions derived from pollen-based reconstructions over the last 21 000 years, which are suitable for the evaluation of Earth-system-model-based paleo-megabiome simulations. We identified strong deviations between pollen- and model-derived megabiome distributions in the circum-Arctic and Tibetan Plateau areas during the Last Glacial Maximum and early deglaciation and in northern Africa and the Mediterranean region during the Holocene.

Short summary
We present a modern pollen dataset of 555 pollen count records from 307 sites on the Tibetan Plateau (28–40° N and 75–103° E). Our open-access dataset holds various potential applications in paleoecological and paleoclimatic researches. It offers a scientific foundation for reconstructing changes in climate and vegetation over time and enables the assessment of the reliability of pollen assemblages in representing the dynamics of vegetation cover, functional traits, and plant diversity.

A mismatch between model- and proxy-based Holocene climate change may partially originate from the poor spatial coverage of climate reconstructions. Here we investigate quantitative reconstructions of mean annual temperature and annual precipitation from 1908 pollen records in the Northern Hemisphere. Trends show strong latitudinal patterns and differ between (sub-)continents. Our work contributes to a better understanding of the global mean.

Climate reconstruction from proxy data can help evaluate climate models. We present pollen-based reconstructions of mean July temperature, mean annual temperature, and annual precipitation from 2594 pollen records from the Northern Hemisphere, using three reconstruction methods (WA-PLS, WA-PLS_tailored, and MAT). Since no global or hemispheric synthesis of quantitative precipitation changes are available for the Holocene so far, this dataset will be of great value to the geoscientific community.

Short summary
Data–data and data–model vegetation comparisons are commonly based on comparing single vegetation estimates. While this approach generates good results on average, reducing pollen assemblages to single single plant functional type (PFT) or biome estimates can oversimplify the vegetation signal. We propose using a multivariate metric, the Earth mover's distance (EMD), to include more details about the vegetation structure when performing such comparisons.

The objective of this study is present the first gridded and temporally continuous quantitative plant-cover reconstruction for temperate and northern subtropical China over the last 12 millennia. The reconstructions are based on 94 pollen records and include estimates for 27 plant taxa, 10 plant functional types, and 3 land-cover types. The dataset is suitable for palaeoclimate modelling and the evaluation of simulated past vegetation cover and anthropogenic land-cover change from models.

Pollen preserved in environmental archives such as lake sediments and bogs are extensively used for reconstructions of past vegetation and climate. Here we present LegacyPollen 1.0, a dataset of 2831 fossil pollen records from all over the globe that were collected from publicly available databases. We harmonized the names of the pollen taxa so that all datasets can be jointly investigated. LegacyPollen 1.0 is available as an open-access dataset.

Here we present a global chronology framework of 2831 palynological records, including globally harmonized chronologies covering up to 273 000 years. A comparison with the original chronologies reveals a major improvement according to our assessment. Our chronology framework and revised chronologies will interest a broad geoscientific community, as it provides the opportunity to make use in synthesis studies of, for example, pollen-based vegetation and climate change.

Short summary
Short summary
The Tibetan Plateau is quite remote, and it is difficult to collect samples on it; the previous modern pollen data are located on a nearby road, and there is a large geographic gap in the eastern and central Tibetan Plateau. Our novel pollen data can fill the gap and will be valuable in establishing a complete dataset covering the entire Tibetan Plateau, thus helping us to get a comprehensive understanding. In addition, the dataset can also be used to investigate plant species distribution.

Short summary
We present an ice-free season temperature based on brGDGTs over last 15 kyr on the eastern Tibetan Plateau (TP). The result shows that Holocene Thermal Maximum occurred during 8–3.5 ka, which lags behind pollen-based temperature recorded in same core, indicating a significant seasonal bias between different proxies. We also investigated previously published brGDGT-based temperatures on the TP to determine the pattern of Holocene temperature changes and possible reasons for the diverse records.
