The Colorado River Basin is an important natural resource for the semi-arid southwestern United States (US), where it provides water to more than 40 million people. While nearly 1.5°C of anthropogenic warming has occurred across this region from 1880s 2021, climate models show little agreement in precipitation change during same historical period, with no trend mean latest (sixth) generation Gl...

Abstract Studying tropical hydroclimate and productivity change in the past is critical for understanding global climate dynamics. Northwest Australia an ideal location investigating Australian monsoon dynamics, variability of Indonesian Throughflow (ITF), their impact on Pacific warm pool evolution, which remain poorly understood during 40 kyr world mid‐early Pleistocene. In this study, we pre...

The Qaidam Basin in the core area of arid Inner Asia has been considered undergoing continuous aridification over Cenozoic. However, is marked with expanded lacustrine sedimentation during Oligocene, which contrasts fluvial or deltaic facies stratigraphically below (Eocene) and above (Miocene-present). Oligocene expansion challenges idea persistent aridification. To solve conundrum, we reconstr...

During the Messinian (7.24–5.33 Ma), highly dynamic Mediterranean environment was concomitantly governed by global climate changes and regional tectonic activity affecting connectivity to ocean. The combined effects generated extreme rapid paleoenvironmental culminating in Salinity Crisis (MSC; 5.96–5.33 Ma). Here, we reconstruct conditions recorded Agios Myron section (Crete Island, Greece) be...

Abstract The mid-Pleistocene transition 1.25 to 0.6 million years ago marked a major shift in global climate periodicity from 41,000 around 100,000 without concomitant orbital forcing shift. Here, we investigate Asian dynamics associated with two extreme glacial loess coarsening events at the onset and middle of by combining new existing grain size magnetic susceptibility records Chinese Loess ...

The timing history and driving mechanisms of C4 expansion and Tibetan uplift are hotly debated issues. Paleoenvironmental evidence from within the Tibetan Plateau is essential to help resolve these issues. Here we report results of stable C and O isotope analyses of tooth enamel samples from a variety of late Cenozoic mammals, including deer, giraffe, horse, rhino, and elephant, from the Qaidam...
