Correcting Underestimated Internal Variability Fails to Reconcile Models With Observed Pacific SST Gradient Strengthening

Geophysical Research Letters, Volume 53, Issue 12, 28 June 2026.
Abstract The equatorial Pacific zonal sea surface temperature (SST) gradient has strengthened since 1980, yet fewer than 1% of CMIP6 simulations reproduce this trend. We test whether underestimated internal variability explains this mismatch. Extreme El Niño events enhance interdecadal variability of the gradient, but CMIP6 models simulate them too ...

Reduced Distinctiveness of Extreme El Niño Teleconnections in Warmer Climates

Geophysical Research Letters, Volume 53, Issue 12, 28 June 2026.
Abstract In today's climate, extreme El Niño events (e.g., 1982–1983, 1997–1998) generate stronger and eastward‐shifted teleconnections relative to moderate El Niño and La Niña events, leading to distinct North American impacts such as enhanced rainfall over California and warming over northeastern North America.

ERA5‐Based Convective Environments Favorable for Tornadoes in Southern China

Geophysical Research Letters, Volume 53, Issue 12, 28 June 2026.
Abstract Tornado occurrences vary significantly across regions in the globe, attributable in part to variations in regional climate and topography. This study analyzes the long‐term convective environments associated with tornadoes in southern China, a region previously identified as having the most favorable meteorological conditions for tornadoes ...

Anomalous Westerly Shifts in the Medieval Warm Period Disrupted Centennial East Asian Winter‐summer Monsoon Synchrony Since 2500 BP

Geophysical Research Letters, Volume 53, Issue 11, 16 June 2026.
Abstract Understanding past East Asian monsoon dynamics is crucial for projecting its responses to substantial climate forcing under future global warming scenarios. However, the relationship between East Asian Winter monsoon (EAWM) and summer monsoon (EASM) in the late Holocene remains under debate.

Early Establishment of Far Eastern Pacific Warming Shapes Distinctive Air‐Sea Coupling in the 2023–2024 El Niño

Geophysical Research Letters, Volume 53, Issue 11, 16 June 2026.
Abstract This study investigates the role of far eastern Pacific (FEP) sea surface temperature anomalies (SSTA) in shaping El Niño development, focusing on the 2023–2024 event. Unlike most post‐1980 El Niño events, which are characterized by central–eastern Pacific–dominated growth and strong air–sea coupling, the 2023–2024 event featured early FEP ...

Reversible Regime Change: Climate‐Driven Phytoplankton Community Shifts in the Cariaco Basin, Venezuela

Journal of Geophysical Research: Biogeosciences, Volume 131, Issue 6, June 2026.
Abstract Phytoplankton communities are integral to oceanic biogeochemical cycles and are sensitive indicators of climate‐driven environmental variability. Long‐term time series capture this variability, allowing us to unravel the effects of environmental change on local communities.

Global Drivers of Phytoplankton Phenology Trends

Global Change Biology, Volume 32, Issue 6, June 2026.
Observations and a global biogeochemical model were used to examine recent shifts in phytoplankton phenology at the global scale. Sea surface temperature trends emerge as the strongest predictor of these changes, relative to the other drivers considered, and are associated with earlier initiation, later termination, and longer growing periods ...

Coral Reefs in the Indonesian Seas Threatened by Heat and Cold Stress

Geophysical Research Letters, Volume 53, Issue 9, 16 May 2026.
Abstract Heat accumulation and rising sea surface temperatures (SST) are currently major stressors for coral reefs worldwide. Coral reefs are also impacted by cool SST anomalies, although the dynamics of cold stress events are less well understood. Here, we estimate coral bleaching metrics in the Indonesian Seas using a high‐spatial‐temporal‐resolution

Mechanisms for Decadal Variability of Ocean Heat Uptake Inferred From Adjoint Sensitivities

Geophysical Research Letters, Volume 53, Issue 8, 28 April 2026.
Abstract The occurrence of a period of slowdown in surface air temperature increase from 1998 to 2013 despite continued greenhouse gas emissions (the warming hiatus) has suggested that ocean heat uptake (OHU) is susceptible to decadal variability. Here, we identify mechanisms that lead to decadal changes in OHU to revisit the origin of the warming ...
