Ocean heat content in 2025 - Nature Reviews Earth & Environment As of 2025, the global full-depth ocean heat content (OHC) has risen by 481 ± 48 ZJ since 1960, with a pronounced increase of 24 ± 6 ZJ from 2024 to 2025. The highest elevations in OHC were measured in the Southern and Pacific Oceans.

🌡️ Ocean heat reached a record high in 2025, driven mainly by human activity.

Heat is building across the global ocean, especially in upper layers, increasing risks such as #SeaLevelRise, stronger storms and ecosystem stress. https://www.nature.com/articles/s43017-026-00775-1

The science is clear.

The cryosphere is changing fast.
The real question is whether politics and policy can move faster than the melt.

#SeaLevelRise is amplified in the Bay of Fundy; it is eroding grasses that have existed here for 1000’s of years.

These fragile mud flats are home to the highest populations of brine shrimp that support shore birds.

A More Troubling Picture of Sea Level Rise Is Coming into View Scientists have uncovered a "blind spot" in the research on rising seas, revealing that tens of millions of people thought safe from coastal flooding are at risk of inundation. Across much of the world, sea levels are higher than previously assumed and land is sinking faster.

Fig. 3. Spatio-temporal classification and attribution of subsidence hot spots across Java Island. (A) Spatial distribution of subsidence hotspot derived from k-means clustering of InSAR-derived VLM time series and spatial coherence refinement using DBSCAN. Each color represents a unique cluster (cluster ID). Detailed figure of each cluster is shown in fig. S9. (B) Conceptual model showing the dominant land use or geologic mechanism associated with each group of clusters, determined using multivariate DTW of their temporal signatures. Clusters are grouped into six classes: coastal alluvial compaction (clusters 1 to 4, 17, and 21), deltas and river channels (clusters 5, 11, and 23), industrial areas (clusters 7, 10, 12 to 14, and 24), residential areas (clusters 6, 8, 9, 15, 16, and 25 to 27), agricultural areas (clusters 18 to 20, 22, and 28), and the Lusi mud volcano (cluster 29). The underlying basemap in (A) is provided by Esri, TomTom, Garmin, FAO, NOAA, and USGS.

What are the health impacts of sea-level rise, and who should pay? A core human need is fresh water, co-chair of new Lancet Commission says – with global empathy, connection and imagination all needed to mitigate climate harms

In November in Solomon Islands, the former Tongan health minister Dr Saia Ma’u Piukala stood outside the main hospital in Honiara and “watched seawater lapping at its outer walls”.

When saltwater intrudes into freshwater supplies, health suffers. When floods overwhelm sanitation systems, diseases spread. When farmland is inundated by king tides, nutrition deteriorates.
