Summary: By simulating the evolution of the earth system-biome and analyzing extensive hominin fossil and archaeological data, we examine the impact of vegetation and ecosystem diversity on hominin adaptation and migration. The findings indicate that early African hominins primarily inhabited open environments such as grasslands and dry shrublands. As they migrated to Eurasia, hominins gradually adapted to a wider range of biomes. Furthermore, our ancestors actively selected spatially diverse environments, as evidenced by the correlation between the location and age of hominin sites and simulated regional biomes. In light of the quantitative results, a new diversity hypothesis is proposed, suggesting that Homo species, particularly Homo sapiens, possessed special abilities to adapt to landscape mosaics.

Summary: During the extreme warming period, surface temperatures in glacial regions of the Tibetan Plateau have increased faster than non-glacial areas, and the duration and intensity of glacier surface heatwaves have significantly increased. These changes may pose potential threats to the sustainability of glacier water resources and increase the risk of glacier related hazards.

Summary: The research reveals distinct biological and cultural shifts between different hominin groups in Southwest Asia, with limited records from the vast arid region. Through studying sedimentary sequences, stone tools, and vertebrate fossils in the Nefud Desert, it is discovered that there were at least five early human expansions into the Arabian interior, coinciding with periods of reduced aridity. This suggests that ancient humans were sensitive to climate change and potentially migrated during times of decreased aridity.

Summary: The study found that most vegetated areas in the Tibetan Plateau are showing a greening trend, with climate change explaining only a portion of the observed greening. The combination of terrain, baseline climate, and soil properties also play a significant role in regulating this greening phenomenon, highlighting the importance of mountainous effects in response to climate change.

Summary: This paper reconstructs the composition and changes of vegetation in the Qinghai-Tibetan Plateau (QTP) over the past 15,000 years using pollen assemblages. The study identifies six forest biomes mainly in the southeastern plateau, which gradually expanded along the eastern margin during the early to mid-Holocene. The alpine meadow biome also expanded westward towards lower latitudes and higher altitudes during the early Holocene. The study also found migration patterns for the alpine steppe biome, which moved eastward during the late Holocene. The dominant biome, temperate steppe, was widely distributed on the QTP with minor migration patterns. The desert biome was mainly found in the northwestern plateau and the Qaidam Basin. The study highlights the importance of monsoonal precipitation in the development of alpine ecosystems and the influence of regional moisture brought by the mid-latitude Westerlies on desert vegetation. Temperature changes played a relatively minor role in alpine vegetation variations but had more significant impacts on forest biomes.

Summary: This study investigated the changes in the date of peak vegetation growth and its climatic controls over the alpine grasslands of the Tibetan Plateau (TP). The results showed that the date of peak vegetation growth advanced by 0.81 days decade-1 during 2001-2020, with the most significant shift occurring in the semi-humid eastern TP. The advancing peak growth in this region was mainly influenced by the timing of peak precipitation and shifted towards the timing of peak temperature. The study also highlighted the importance of water availability in vegetation growth over the TP and suggested a transition from thermal-constrained to water-constrained ecosystem under the rapid warming climate.

Summary: The mechanisms of the Asian monsoon system in the late Oligocene-early Miocene are not fully understood. A reliable paleogeographic reconstruction for the early Miocene is essential for understanding past climatic change and for early Miocene climate modelling studies. This study presents a new reconstruction of global paleogeography for the early Miocene and provides updated geological data for key regions and features that control climate change.

Summary: The upper sandy loess unit L9 on the Chinese Loess Plateau represents aeolian deposition under conditions of extreme aridification, but the forcing mechanism is still controversial. Paleomagnetic studies show that in the eastern CLP, the coarsest part of L9 is remagnetized and has a normal geomagnetic polarity, while in the western CLP, it records a primary reverse polarity. This spatially inconsistent magnetization pattern is mainly due to different magnetic carriers in the two regions (hematite in the west and magnetite in the east), suggesting different dust provenance. This spatial contrast is attributed to the episodic uplift of the northeastern Tibetan Plateau, which also caused extreme aridification of the East Asian interior at approximately 900 ka.

Summary: This study investigates the inversion of past ground surface temperature changes using borehole temperature measurements. The results show that there has been a rise of approximately 2K since 0.1-0.6 thousand years before present (BP) and a rise of approximately 10K since 20 thousand years BP. The findings emphasize the importance of borehole heat-flow profiles as a record of climate changes and the need for climate correction in heat-flow determinations.

Summary: Plate tectonics play a vital role in regulating atmospheric CO2 concentration over geological timescales. Current research on tectonic CO2 dynamics requires the development of models that include four modules: simulating carbon processes, calculating CO2 fluxes, reconstructing carbon cycling within tectonic scenarios, and comparing with atmospheric CO2 history data. The primary technical challenge lies in simulating the complex carbon dynamics across different scales in time and space.

Summary: We present a 12-Myr long South Asian summer monsoon (SASM) record based on the strontium and neodymium isotopic composition of detrital components at IODP Exp. 359 Site U1467. Provenance analysis shows that dust enriched in eNd from northeastern Africa and the Arabian Peninsula was transported to the study site by monsoonal and Shamal winds during the summer monsoon season. We propose a two-step weakening of the SASM wind since approximately 12 million years ago based on the eNd record. Climate modeling results support this observation, indicating that the SASM evolution was mainly controlled by changes in the gradient between the Mascarene High and the Indian Low, caused by growth of interhemispheric ice sheets since the Middle Miocene.

Summary: Volcanic arc degassing plays a significant role in atmospheric CO2 levels and paleoclimate changes. The Neo-Tethyan decarbonation subduction is believed to have influenced Cenozoic climate changes, and this study provides further evidence by analyzing subduction scenarios and paleoclimate parameters. The findings suggest a causal link between subduction processes, carbon-rich sediments subducting, and global warming.

Summary: We derived a record of abyssal ventilation spanning 4.7 million years and evaluated its linkage to Antarctic bottom water (AABW) formation by analyzing marine ferromanganese nodules from the eastern Pacific. Our findings showed a relative weakness in abyssal ventilation during the early Pliocene, with a persistent intensification from 3.4 million years ago. We identified seven episodes of AABW formation collapse since the late Pliocene, coinciding with key stages of Northern Hemisphere glaciation, indicating a possible link between the collapse events and global glaciation.

Summary: Landforms on the Martian surface provide valuable insights into past surface processes, but the modern hydroclimatic conditions on Mars are still not well understood. This study reports the discovery of various surface features on salt-rich dunes in southern Utopia Planitia, suggesting the involvement of saline water from thawed frost/snow as the most likely cause. The findings shed light on the more humid conditions of the modern Martian climate and have important implications for future exploration missions searching for signs of extant life.

Summary: This study reconstructed annual precipitation of the Asian summer monsoon (ASM) and Australian summer monsoon (AusSM) from 1588 to 2013 (1588 to 1999) to examine the relationship between ENSO and monsoon and how it has changed. The results showed that the ENSO-monsoon relationship has become stronger since 1850, indicating the influence of anthropogenic climate warming. Climate model projections further suggested that global warming can strengthen the ENSO-monsoon association and synchronize ASM and AusSM variations.

Summary: Establishing the temporal sequence of the Middle-Late Jurassic Yanliao Biota is crucial for understanding vertebrate evolution, but the lack of reliable and precise age data hinders progress. In this study, the authors propose a temporal sequence for the Yanliao Biota with precise age constraints, showing that the major vertebrate-bearing strata span from 164 Ma to 157 Ma in age. Incorporating this updated temporal framework into mammaliaform phylogeny reveals new insights into mammal evolution.

Summary: This study conducted environmental magnetic analyses on the Minle loess section and found that the magnetic susceptibilities of palaeosols in this region are mainly influenced by superparamagnetic and single-domain maghemite and/or magnetite. The section is divided into four substages, providing a complete record of Holocene climatic evolutions. The differences in climatic records across the Chinese loess are attributed to precipitation, effective humidity, and aeolian geomorphological processes.

Summary: The Yanshanian Orogeny during the Early Cretaceous phase B involved compression and extension, and the mechanism of tectonic transition is still contentious. The Tuchengzi Formation below the angular unconformity might provide insight into this transition. Anisotropy of magnetic susceptibility and U-Pb geochronological studies on the Tuchengzi Formation reveal N-S compression in the western and middle segments and NW-SE compression in the eastern part during its deposition.

Summary: Climate during the last glacial period was characterized by abrupt and millennial-scale variations in temperature, especially in Greenland (Daansgard-Oeschger events) and Antarctica (AIM events). This study presents a continuous record of stable isotopes from planktic and benthic foraminifera at a site in the southwestern Iberian margin, providing insights into millennial climate variability (MCV) during the past 1.5 million years. The results demonstrate that MCV was a persistent feature of glacial climate, with modulation by orbital forcing and a strong correlation with North Atlantic surface temperature and deep-water circulation.
