Today’s Highlights
A slowdown in the Atlantic meridional overturning circulation is shown to intensify atmospheric rivers along mid-latitude western coasts, with major implications for future extreme precipitation and flooding. A new Phanerozoic temperature reconstruction reveals that Earth’s climate has been far more tightly regulated than oxygen isotope records previously suggested, constraining global mean temperature to a narrower range over 539 million years. Additionally, a high-resolution Holocene soil temperature record from the Chinese Loess Plateau demonstrates how mid-Holocene cooling shaped the geographic spread of millet agriculture in East Asia.

The slowing of the Atlantic meridional overturning circulation (AMOC) under anthropogenic warming has been suggested to significantly impact Earth’s climate. Here, we isolate and quantify the AMOC impact on atmospheric rivers (ARs) across the twenty-first century using coupled climate model simulations. We find that a weakened AMOC promotes AR frequency in mid-latitudes by intensifying the prevailing westerly winds, especially at the west coast of North America, which enhances northward moisture transport. The AMOC slowdown also amplifies AR intensity, increasing vertically integrated water vapor transport by up to 10% by the end of the century. These AMOC-driven AR changes contribute substantially to projected precipitation increases over western North America and Europe. Our findings reveal AMOC as a key modulator of AR behavior in a warming climate, with implications for regional water resources and extreme precipitation risk.

Knowing the past temperature of the Earth is crucial for understanding the mechanisms driving climate change and biosphere evolution, but there is significant debate about the range of past temperature variation. Previous interpretations, largely based on oxygen isotope records, suggest that global temperature has generally declined over the past 539 million years, but substantial uncertainties persist. In this study, we introduce an independent estimate for long-term temperature based on the distribution of climate-sensitive lithologies (glacial deposits, evaporites, coals, and laterites) integrated with plate tectonic reconstructions. Our results suggest that Phanerozoic global mean temperature has been regulated within a relatively narrow range, challenging the conventional view of a long-term cooling trend. This tighter thermal regulation implies the existence of effective negative feedbacks — likely involving the silicate weathering cycle — that have maintained Earth’s surface temperature within habitable bounds over geological time.
Soil temperature fluctuations modulated millet agriculture evolution in Neolithic East Asia

Millet agriculture was foundational to the emergence of complex societies in Neolithic East Asia, yet the environmental mechanisms shaping its spatiotemporal development remain unresolved. Here, we present a high-resolution reconstruction of Holocene growing-season soil temperature from biomarker proxies in a precisely dated loess sequence from the central Chinese Loess Plateau. Our data reveal a pronounced ~3 °C soil cooling between ~7.5 to 6.0 thousand years B.P. (kyr B.P.), followed by rapid warming and millennia-long relatively stable conditions. By integrating archaeological datasets with transient climate simulations, we show that this mid-Holocene soil cooling which reflects coupled climatic forcing and vegetation-related land surface changes likely compressed the thermally suitable niche for frost-sensitive millets, contributing to a southward displacement of cultivation and delaying large-scale agricultural expansion until the subsequent soil temperature recovery after ~6.0 kyr B.P. These findings suggest that large-amplitude soil temperature fluctuations acted as a modulating climatic constraint on the geographic distribution and development trajectory of millet agriculture in East Asia, providing refined insights into climate–society interactions during the Neolithic.
