Warming oceans likely to raise sea levels 30cm by end of century – study
“Seawater temperature is rising faster than predicted, which is likely to worsen extreme weather events around the world
The world’s oceans are warming at a faster rate than previously estimated, new research has found, raising fresh concerns over the rapid progress of climate change.
Warming oceans take up more space, a process known as thermal expansion, which the study says is likely to raise sea levels by about 30cm by the end of the century, on top of the rise in sea levels from melting ice and glaciers. Warmer oceans are also a major factor in increasing the severity of storms, hurricanes and extreme rainfall”

Climate change from human activities mainly results from the energy imbalance in Earth's climate system caused by rising concentrations of heat-trapping gases. About 93% of the energy imbalance accumulates in the ocean as increased ocean heat content (OHC). The ocean record of this imbalance is much less affected by internal variability and is thus better suited for detecting and attributing human influences (1) than more commonly used surface temperature records. Recent observation-based estimates show rapid warming of Earth's oceans over the past few decades (see the figure) (1, 2). This warming has contributed to increases in rainfall intensity, rising sea levels, the destruction of coral reefs, declining ocean oxygen levels, and declines in ice sheets; glaciers; and ice caps in the polar regions (3, 4). Recent estimates of observed warming resemble those seen in models, indicating that models reliably project changes in OHC.
