Short summary
We present an unprecedented record of Indian summer monsoon (ISM)-induced vegetation changes for MIS 11, a key interglacial. Site U1446 pollen data and models show that ISM-vegetation shifts stem from an interplay of dominant forcings based on boundary conditions. Insolation is the main driver during MIS 11c interglacial conditions, akin to future scenarios, while ice volume and CO₂ prevail in the glacial inception. Superimposed changes are marked by prominent forest contractions and expansions.

Short summary
The Maldives Inner Sea (northern Indian Ocean) offers an excellent study site to explore the impact of climate and sea-level changes on carbonate platforms. The sediments from International Ocean Discovery Program (IODP) Site U1467 have been studied to determine the drivers of carbonate production in the atolls over the last 1.3 million years. Even though sea level is important, the intensity of the summer monsoon and the Indian Ocean dipole probably modulated the production at the atolls.

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
This paper is about regional sea level during Marine Isotope Stage 3 (MIS 3) with broader implications for eustatic sea level during MIS 3. There is no current good constraint. We provide evidence that regional sea level in the northeast Mediterranean had to remain low, below 80 mbsl from seismic and geochemical observations. This has implications for understanding eustatic sea level fluctuations during MIS 3, modelling glacio-isostatic adjustment, and ice sheet/terrestrial interactions.

We present a past sea surface temperature and paleoproductivity record over the last 150 000 years for ODP Site 1234 (Chilean margin). We tested the applicability of long-chain diol proxies for the reconstrucion of SST (LDI), past upwelling conditions (diol index), and nutrient concentrations (NDI). The LDI likely reflects past temperature changes, but the diol index and NDI are perhaps more indicative of Proboscia diatom productivity rather than upwelling and/or nutrient conditions.

Short summary
The deep ocean is the major store of heat and carbon in Earth's surface environment and thus has a major impact on climate. Waters that fill the deep ocean come from the North Atlantic and the Southern Ocean, but there is debate on their relative importance. Here we reconcile previous estimates using deep sea phosphate and oxygen data. We show that although a large volume of deep water comes from the south, this does not spend enough time in the southern surface to fully exchange heat and CO2.

We use model simulations to investigate mechanisms of similar Iceland--Scotland overflow (outflow from the Nordic seas) and North Atlantic sea surface temperature variability, suggested from palaeo-reconstructions (Mjell et al., 2015). Our results indicate the influence of Nordic Seas surface temperature on the pressure gradient across the Iceland--Scotland ridge, not a large-scale link through the meridional overturning circulation, is responsible for the (simulated) co-variability.

By studying microfossils from sediments in Upernavik Fjord we investigate the role of ocean warming on the retreat of Upernavik Isstrøm during the past ~90 years. The reconstruction of Atlantic-derived waters shows a pattern similar to that of the Atlantic Multidecadal Oscillation, corroborating previous studies. The response of Upernavik Isstrøm to ocean forcing has been variable in the past, but the current retreat may be temporarily tempered by cooling bottom waters in the coming decade.

Short summary
Reconstructions of the last 2000-year climatic conditions along the Iberian Margin, a vulnerable region regarding current global warming, reveal a long-term cooling in sea surface temperature (SST) ending with the 19th century and centennial-scale variability that exposes warm SSTs throughout the first 1300 years followed by the colder Little Ice Age. The Industrial Era starts by 1800 CE, with an SST rise and a second increase in SST at ca. 1970 CE, particularly marked in the southern region.

The observed changes in the presented proxy records indicate variations in both the continental runoff and the marine influence, related to regional climatic variability. Therefore, we put forward the suggestion that global atmospheric changes (related to changes in SAMS and SACZ intensity) have made an impact on the hydrodynamics and, consequently, on the local sedimentation regime and the inner Uruguayan continental shelf over the past 1200 cal yr BP (AD 750–2000).

Short summary
Annually laminated sediments from the NE Bering Sea reveal a decadal-scale correlation to Greenland ice core records during termination I, suggesting an atmospheric teleconnection. Lamination occurrence is tightly coupled to Bølling-Allerød and Preboreal warm phases. Increases in export production, closely coupled to SST and sea ice changes, are hypothesized to be a main cause of deglacial anoxia, rather than changes in overturning/ventilation rates of mid-depth waters entering the Bering Sea.

Short summary
This study focuses on understanding climatic and oceanographic variations that took place during the last 1000 years. We studied sediment samples from the Labrador Sea, looking for evidence of events of freshwater and iceberg discharges to this region. The importance of this study is to evaluate when these events happened and their consequences. The freshening of the Labrador Sea region may have played a major role in promoting cooling during the 15th to 19th centuries.
