Short summary
A coral reconstruction of past climate shows changes in the seasonal cycle of sea surface temperature in the SE tropical Indian Ocean. An enhanced seasonal cycle suggests that the tropical rainfall belt shifted northwards between 1855–1917. We explain this with greater warming in the NE Indian Ocean relative to the SE, which strengthens surface winds and coastal upwelling, leading to greater cooling in the eastern Indian Ocean south of the Equator.

Short summary
Year-to-year variations in the weather conditions over the Indian Ocean have important consequences for the substantial fraction of the Earth's population that live near it. This work looks at how these variations respond to climate change – both past and future. The models rarely agree, suggesting a weak, uncertain response to climate change.

We examine the sea-surface temperature response to an interval of climate ~ 3.2 million years ago, when CO2 concentrations were similar to today and the near future. Our geological data and climate models show that global mean sea-surface temperatures were 2.3 to 3.2 ºC warmer than pre-industrial climate, that the mid-latitudes and high latitudes warmed more than the tropics, and that the warming was particularly enhanced in the North Atlantic Ocean.

Short summary
The oxygen isotopic ratio of water in fluid inclusions in speleothems is an important proxy for the changes in past hydroclimate and temperatures. This isotopic ratio, however, may be affected by isotopic exchange between the water and the host calcite. Here we evaluate this exchange reaction based on a laboratory experiment. We demonstrated that the exchange was detectable but not significant for temperature reconstruction, likely because the reaction occurred only with a thin calcite layer.

Climate reorganization during the early neoglacial anomaly (ENA) may explain the Harappan civilization metamorphosis from an urban, expansive culture to a rural, geographically-confined one. Landcover change is a candidate for causing this climate instability. During ENA agriculture along the flood-deficient floodplains of the Indus became too risky, which pushed people out. In the same time the Himalayan piedmont received augmented winter rain and steady summer precipitation, pulling people in.

Facilitated by a robust chronology with closely spaced U-Th ages, replicated sub-decadal-resolved δ18O records of two stalagmites from Sanxing Cave, Southwest China, express Asian Summer Monsoon (ASM) history from 79.0 ± 0.2 to 75.7 ± 0.2 thousand years before present (kyr BP, before AD 1950) to reveal detailed structure of MIS 5a/4 transition and Chinese Interstadial (CIS) 21.

Recent Southern Hemisphere (SH) atmospheric circulation, predominantly driven by stratospheric ozone depletion over Antarctica, has caused changes in climate across the extratropics. We present evidence that the Brazilian coast may have been impacted from both wind and sea surface temperature changes derived from this process. Skeleton analysis of massive coral species living in shallow waters off Brazil are very sensitive to air–sea interactions and seem to record this process.

Short summary
The upper part of stalagmite ky1 (from top to 42.769 mm depth), consisting of 678 laminae, was collected from a cave in northern China, located in the East Asia monsoon area. The time of deposition ranges from AD 1217±20 to 1894±20. The analysis shows that both the variations in the thickness of the laminae themselves and the fluctuating degree of variation in the thickness of the laminae of stalagmite ky1 have obviously staged characteristics and synchronized with climate.

1. We have reconstructed new meridional thermal and precipitation stacked records in the Indo-Pacific Warm Pool (IPWP) during the last termination.
2. Meridional thermal gradient variations in the IPWP show tight links to the Northern Hemisphere millennial timescales event.
3. Anomalous warming in the south IPWP region could induce the southward shifting of the Intertropical Convergence Zone (ITCZ) in the IPWP during the Heinrich 1 and Younger Dryas events.

In this study, we train machine learning models on tree rings, speleothems, and instrumental rainfall to estimate seasonal monsoon rainfall over India over the last 500 years. Our models highlight multidecadal droughts in the mid-seventeenth and nineteenth centuries, and we link these to historical famines. Using techniques from explainable AI, we show our models use known relationships between local hydroclimate and the monsoon circulation.

We evaluated the South American Summer Monsoon over the last millennium and dynamically interpreted the principal modes of variability. We find the spatial patterns of the monsoon are an intrinsic feature of the climate modulated by external forcings. Multi-centennial mean state departures during the Medieval Climate Anomaly and Little Ice Age show regionally coherent patterns of hydroclimatic change in both a multi-archive network of oxygen isotope records and isotope-enabled climate models.

We provide new global estimates of changes in surface temperature, surface heat flux, and continental heat storage since preindustrial times from geothermal data. Our analysis includes new measurements and a more comprehensive description of uncertainties than previous studies. Results show higher continental heat storage than previously reported, with global land mean temperature changes of 1 K and subsurface heat gains of 12 ZJ during the last half of the 20th century.

High-resolution multiproxy analysis of sediment core from a high-elevation lake on Corsica allows us to reconstruct past African dust inputs to the western Mediterranean area over the last 3 millennia. Millennial variations of Saharan dust input have been correlated with the long-term southward migration of the Intertropical Convergence Zone, while short-term variations were associated with the North Atlantic Oscillation and total solar irradiance after and before 1070 cal BP, respectively.

The western USA is frequently affected by multiannual summer droughts. They can be separated into two groups with distinct spatial patterns. This study analyzes the atmospheric circulation during multiannual droughts in a new 3-D climate reconstruction. We confirm two distinct drought types differing with respect to atmospheric circulation as well as sea surface temperatures. Our results suggest that both the Pacific and the extratropical North Atlantic region affect North American droughts.

The South American summer monsoon (SASM) is the most important climate system of South America. However, little is known about its long-term variability. Here we present a new SASM reconstruction from Lago Chungará in the southern Altiplano (18°S). We show important changes in SASM precipitation at timescales of centuries. Our results suggest that SASM variability was controlled not only by tropical climates but was also influenced by precipitation outside the tropics.

We found that the tree-ring earlywood width (EWW) of Pinus tabuliformis from the eastern Qinling Mountains (central China) showed stronger response to May–July scPDSI than the tree-ring total width and latewood width. Therefore, variations in May–July scPDSI were reconstructed back to 1868 CE using the EWW chronology. The reconstruction exhibited a strong in-phase relationship with the East Asian summer monsoon intensity before the 1940s, which was different from that found in recent decades.

This paper presents a millennial δ18O series and the reconstruction of the maximal temperature. The maximal replication and annual resolution have been obtained by using cohort sampling method. Three contrasted climatic periods have been identified: the medieval warm period (~997-1250; the warmest), the little ice age (~1450-1880) and the modern period (1970-2000) that is one of the fastest warming over the last millennium.

All regional monsoons belong to a cohesive global monsoon circulation system, albeit thateach regional subsystem has its own indigenous features. A comprehensive review of global monsoon variability reveals that regional monsoons can vary coherently across a range of timescales, from interannual up to orbital and tectonic. Study of monsoon variability from both global and regional perspectives is imperative and advantageous for integrated understanding of the modern and paleo-monsoon dynamics.
