Southern Portugal hydroclimate of the last millennium from near‐annually resolved speleothem records

Journal of Quaternary Science, Volume 41, Issue 8, Page 1454-1471, November 2026.
ABSTRACT Hydroclimate in Portugal is influenced by the North Atlantic subtropical high‐pressure system (the Azores High) and by internal climate modes, most prominently the North Atlantic Oscillation, which may shift in position and/or intensity due to anthropogenic climate change.

Waves of range dynamics and gene flow characterize the biogeographic history of Litsea elongata, a dominant tree in East Asian evergreen broadleaved forests

PLANTS, PEOPLE, PLANET, Volume 8, Issue 6, Page 2177-2191, November 2026.
Evergreen broadleaved forests (EBLFs) represent an iconic vegetation type in subtropical montane East Asia, but they are experiencing intensifying anthropogenic pressure and increasing habitat fragmentation. Here, using a dominant and widespread tree species characteristic of East Asian EBLFs, we examine its phylogeographic history and evaluate what it

Dynamical structure in paleoclimate data

, 1995
Deterministic chaos in dynamical systems offers a new paradigm for understanding irregular fluctuations. The theory of chaotic dynamical systems includes methods that can test whether any given set of time series data, such as paleoclimate proxy data ...

Tools used to study paleoclimate help in water management [PDF]

, 1998
The meteoric waters within active groundwater systems were in contact with the Earth's atmosphere at some time in the past, ranging from days to millions of years ago.

Enhanced Interdecadal Variability in the WACE and Its Oceanic Drivers

Geophysical Research Letters
As the Earth warms, the “warm Arctic–cold Eurasia” (WACE) has changed noticeably, with enhanced interdecadal variability as the Arctic heats up, particularly over the Barents–Kara Sea region.

What Sets the AMOC's Sensitivity to CO2 Forcing? The Role of Background Mean‐State and Density Balance

Journal of Geophysical Research: Oceans, Volume 131, Issue 11, November 2026.
Abstract The future evolution of the Atlantic Meridional Overturning Circulation (AMOC) under anthropogenic forcing remains highly uncertain, partly because the role of the background ocean state in conditioning AMOC sensitivity is not fully understood.

Imminent Emergence of Permanent Surface Marine Heatwave States Across Global Oceans

Earth's Future, Volume 14, Issue 11, November 2026.
Abstract Marine heatwaves (MHWs) can devastate ocean ecosystems, yet the timing at which anthropogenic changes in MHW characteristics permanently emerge from natural variability at the global scale remains poorly quantified. Here, we present the first global time of emergence analysis of MHW characteristics of the ocean surface using simulations from ...

Extratropical Forcing of Tropical Subsurface Oxygenation Under Future Warming

Global Biogeochemical Cycles, Volume 40, Issue 11, November 2026.
Abstract The global ocean overall is losing oxygen under climate warming, yet most climate models project increasing subsurface (100–1,000 m) oxygen concentrations in the tropical “shadow zones”—poorly ventilated low‐latitude regions of the Indian, eastern Atlantic, and eastern Pacific Oceans.

Latitudinal Heterogeneity in South Asian Monsoon Changes Since the Last Glacial Maximum Revealed by Ganga–Brahmaputra Vegetation Record

Paleoceanography and Paleoclimatology, Volume 41, Issue 11, November 2026.
Abstract Future changes in South Asian climate are expected to amplify flooding and drought, yet the spatial and temporal variability of the South Asian monsoon (SAM) under different climate regimes remains poorly constrained. Here, we present a new marine pollen record from the Bay of Bengal (BoB), informing on the vegetation of the Ganges‐Brahmaputra
