Abstract Pollen data from China for 6000 and 18,000 14 C yr bp were compiled used to reconstruct palaeovegetation patterns, using complete taxon lists where possible a biomization procedure that entailed the assignment of 645 pollen taxa plant functional types. A set 658 modern samples spanning all biomes regions provided comprehensive test this showed convincing agreement between reconstructed present natural vegetation types, both geographically in terms elevation gradients mountain...
Abstract. Anthropogenic methane emissions originate from a large number of relatively small point sources. The planned GHGSat satellite fleet aims to quantify individual sources by measuring column plumes over selected ∼10×10 km2 domains with ≤50×50 m2 pixel resolution and 1 %–5 % measurement precision. Here we develop algorithms for retrieving source rates such measurements. We simulate ensemble instantaneous at 50×50 range atmospheric conditions using the Weather Research Forecasting model...
Abstract A set of general circulation model experiments are conducted to analyze how the poleward energy transport (PET) is related spatial pattern CO 2 radiative forcing. The effects forcing affirmed by comparing conventional doubling experiment, in which inhomogeneous, a homogenization experiments, top atmosphere (TOA), surface, or atmospheric distribution homogenized respectively. In addition, we separate and compare various feedbacks on oceanic PETs, using kernels that have developed for...
Abstract Radiative forcing of a homogeneous greenhouse gas (HGG) can be very inhomogeneous because the is dependent on other atmospheric and surface variables. In case doubling CO 2 , monthly mean instantaneous at top atmosphere found to vary geographically temporally from positive negative values, with range (−2.5–5.1 W m −2 ) being more than 3 times magnitude global value (2.3 ). The vertical temperature change across column (temperature lapse rate) best single predictor for explaining...
Abstract Climate models generally fail to produce a warmer (by as much 0.5 °C) early mid-Holocene than the pre-industrial in global annual temperature, which has been termed Holocene temperature conundrum. Here we use fully coupled atmosphere-ocean general circulation model test whether conundrum can be partially resolved by considering fact that atmospheric dust loading was reduced during mid-Holocene. Our experiments show mean surface increases 0.30 °C and 0.23 for (6 ka) (9 ka),...
Abstract We simulate climate variations in the past 250 million years (Myr), using fully coupled Community Earth System Model version 1.2.2 (CESM1.2.2) with Atmosphere 4 (CAM4). Three groups of simulations are performed, each including 26 simulations, a 10‐million‐year interval. The Control group is constrained by paleogeography, increasing solar radiation, and reconstructed global mean surface temperatures (GMSTs) tuning CO 2 concentrations. No ice sheets prescribed for all except...
Abstract Changes to the large‐scale oceanic circulation are thought slow pace of transient climate change due, in part, their influence on radiative feedbacks. Here we evaluate interactions between CO 2 ‐forced perturbations ocean and cloud feedback a model. Both strongly magnitude spatial pattern surface warming. reduce amount global warming caused by helping maintain low coverage face The is key affecting atmospheric meridional heat transport changes dominant mechanism that responds...
Abstract Severe ozone loss and significant surface warming anomalies in the Siberian Arctic were observed spring 2020. Here, we show that anomalous was likely related to loss. The dramatic March shifted Siberia April May, which largely cools lower stratosphere leads an increase of high clouds by modifying static stability upper troposphere. This further results longwave radiation at contributes warming. Multiple linear regression demonstrates most April, while Oscillation ice‐albedo feedback...

Abstract The global warming simulations of the general circulation models (GCMs) are generally performed with different ozone prescriptions. We find that differences in distribution, especially upper tropospheric and lower stratospheric (UTLS) region, account for important model discrepancies shown ozone‐only historical experiment Coupled Model Intercomparison Project Phase 5 (CMIP5). These include high cloud fraction, temperature, water vapor. Through a set experiments conducted by an...
Abstract Climate change plays an important role in the transition of ecosystems. Stratigraphic investigations have suggested that Asian interior experienced frequent transitions between grassland and desert ecosystems as a consequence global climate change. Using maternally bi-parentally inherited markers, we investigated population dynamics Agriophyllum squarrosum (Chenopodiaceae), annual pioneer plant endemic to mobile sand dunes. Phylogeographic analysis revealed A. could originate from...
Abstract Lower Stratospheric water vapor (SWV) is one of important drivers global climate change. Increases and decreases in lower SWV have been found to strengthen offset warming effects, respectively. Using several data sets, we find that sea surface temperature (SST) the past 100 years has caused an increase SWV. SST over tropical Indian Ocean western Pacific resulted a drier stratosphere. However, Atlantic significantly wetter stratosphere main contributor increasing trend years. The...
Riverine sediment flux on the Qinghai-Tibet Plateau follows separate trends in different headwater basins because of complicated pathways under global warming. Here we successfully reconstructed historical fluxes from seven at 25 hydrological stations during 1982 ~ 2022 using a conceptual Multivariate Climate Elasticity Model based Taylor expansion and revealed bifurcation trend. Significantly increasing occurred five stations, caused either by elevated runoff increased precipitation...
Variations in stratospheric atmospheric circulation significantly impact tropospheric weather and climate. Understanding these variations not only aids better prediction of climate but also provides guidance for the development flight trajectories aircraft. Our understanding stratosphere has made remarkable progress over past 100 years. However, we still lack a comprehensive perspective on large-scale patterns circulation, as is typical complex system. To address this gap, employed eigen...
