Summary: The Arctic is currently experiencing significant warming, which has widespread impacts on global climate. A new study suggests that Indian Ocean warming contributes to the Arctic warming through enhancing the Atlantic Meridional Overturning Circulation, leading to increased ocean heat transport from the North Atlantic to the Arctic. This results in upper ocean warming dominating the surface warming in the Arctic. Additionally, despite the net negative contribution of atmospheric heat transport, more warm air is conveyed to the Kara Seas, North Eurasia, and North America sectors, contributing to local warming.

Summary: The Arctic warming-Eurasia cooling trend has had a significant impact on weather patterns and climate extremes at lower latitudes. However, this trend weakened from 2012 to 2021, while subseasonal reversals between the warm Arctic-cold Eurasia and cold Arctic-warm Eurasia patterns became more frequent. The study emphasizes the importance of considering subseasonal changes in predicting climate extremes at mid-to low latitudes.

Summary: Observations show that China is experiencing greater warming compared to the United States, and climate models have failed to accurately capture this difference. The discrepancy in warming trends is due to a stronger climate response to external factors in China. The study highlights the importance of accurately estimating anthropogenic influence on regional warming and provides insights for future climate change mitigation and adaptation strategies.

Summary: The research findings suggest that there has been a significant increase in early positive Indian Ocean Dipole (pIOD) in the past decades, reaching the same frequency as the canonical pIOD. The increase is attributed to the intensified Bjerknes feedback and an early summer monsoon onset, which acts as the major trigger for early pIOD. Model simulations indicate that the increased frequency of early pIOD is likely to continue under greenhouse warming, leading to greater climate variability and more climate extremes in the affected regions.

Summary: This study combines record-breaking statistics with a geographic mode of exploration to introduce a record-breaking map. It shows that high sea surface temperature (SST) records have been broken more frequently than expected, indicating warming over most oceans. The study also evaluates a global climate model (GCM) and finds negligible contribution of internal variability to the observed record-breaking trends. Future forecasts suggest even more frequent high temperature records and less frequent low temperature records.

Summary: Understanding the history and redistribution of ocean excess heat uptake is crucial for assessing climate warming. This study reconstructs ocean heat content change in the 25 degrees N Atlantic hydrographic section and finds that the delayed response of the ocean below 700 m to sea surface temperature change contributes significantly to warming at this latitude. Recent research also shows an increasing net excess heat transport across 25 degrees N, indicating that excess heat redistribution is a key driver of North Atlantic heat gain.

Summary: The study analyzed the role of long-term warming trends in global land SAT variations and found that less than one-third of annual SAT variations were contributed by the warming trend in most regions. In certain areas such as eastern South America, parts of South Africa, southwestern Mediterranean, and Sunda islands, where the absolute warming rate was moderate, but a high ratio of warming trend to SAT variations indicated significant loss of habitat for endemic species. Therefore, the ratio of warming trend to SAT variations may be a better measure compared to the absolute warming rate for assessing local ecoclimatic effects.

Summary: This study demonstrates that the parameter Delta(conv), quantifying the difference in sea surface temperatures between regions of deep convection and the tropical or global average, captures the time-varying pattern effect in global shortwave cloud radiative effect variations. The quantification of cloud feedback critically depends on small changes in the shape of the sea surface temperature probability density distribution, emphasizing the importance of accurate and stable global climate records.

Summary: Sea surface temperature changes in the Mediterranean Sea have significant impacts on both the Mediterranean regions and remote areas. This study reveals, for the first time, that the decadal predictability of Mediterranean SST is influenced by both external forcings and internal variability, except for the winter mean SST in the eastern Mediterranean which is mainly influenced by internal variability. The persistence of Mediterranean SST is significant even compared to the subpolar North Atlantic, and the internally generated variations of Mediterranean SST are associated with the multidecadal variability related to the North Atlantic Oscillation forcing.

Summary: The newly developed normalized red tide index (NRTI) uses Geostationary Ocean Color Imager (GOCI) data to detect red tides by observing spectral characteristics of red tides and sea water in coastal regions. A formulation to calculate red tide density using GOCI data is proposed based on the high correlation between the NRTI and red tide density. The methodology developed in this study is anticipated to be applicable to other ocean color satellite data and regions globally, enhancing the capacity to quantify and track red tides in real-time.

Summary: Extreme value analysis (EVA) using satellite-observed sea surface temperature (SST) data was used to understand and predict long-term return extreme values in the East/Japan Sea (EJS). The peaks-over-threshold (POT) method showed better performance in deriving SST extremes. The calculated 100-year-return SST values were higher than the average value of satellite-observed SSTs over the past decades. The distribution of the SST extremes followed the known seasonal variation, but with enhanced extreme SSTs in early summer and late autumn. Comparison with climate model simulation results showed a slightly smaller extreme SST with a negative bias. This study highlights the potential of the POT method in understanding future oceanic warming based on satellite observed SSTs.

Summary: In this study, the sea-surface winds derived from ASCAT mounted on MetOp-A/B were validated compared to in-situ wind measurements around the Korean Peninsula. The results showed errors in wind accuracy, likely associated with the stratification and dynamics of the marine-atmospheric boundary layer. The ASCAT sea-surface winds tended to be more overestimated than in-situ wind speeds around the Korean Peninsula, especially at weak wind speeds.

Summary: The Sao Francisco River is an important river in Brazil, crossing the semi-arid region. A series of dams have been built along the river for hydropower, changing the flow significantly. A hydrodynamic model was used to simulate the effects of flow changes on saline intrusion in the estuary. The simulations showed an increase in mixing and decrease in river contribution after the dams were built. The results can be used by management agencies to improve water quality for human consumption.

The dynamics of carbonate system parameters were investigated in a coral habitat influenced by seasonal current patterns. Both Oaragonite and pH showed seasonal variations, controlled by dissolved inorganic carbon (DIC) and temperature. Ocean acidification scenarios projected a decrease in Oaragonite amplitude and an increase in hydrogen ion concentration ([H+]) amplitude.

Summary: The Vistula Lagoon, one of the two lagoons on the Polish coast, is economically and environmentally significant. This study aims to calculate the water balance of the lagoon before and after the construction of a canal through the Vistula Spit. The construction of the new connection may impact the lagoon's water balance and its biotic and abiotic environment. Data on precipitation, evaporation, inflow from the catchment, and inflow/outflow through the Strait of Baltiysk were collected for mathematical modeling. The study suggests that the construction of the new canal will not significantly alter the lagoon's water balance but may cause environmental problems.

Summary: We demonstrate that wind-driven Ekman transport enhances the advection and mixing of cells, leading to the transport of colder water from the Surface Antarctic Waters to the warmer waters of the northern Polar Front belt. This mechanism provides cells with a favorable temperature environment, allowing for specific species and community growth rates to develop blooms under non-light limiting macronutrients and iron conditions. Our findings have important implications for increased productivity in a future warming climate.
