Global Sea Level Rise Doubles in Past Decade, New Study Finds
A new study analyzing global sea level rise from 1960 to 2023 reveals that the rate of increase has doubled in the last ten years compared to previous decades. Researchers detailed the contributing factors, including melting ice sheets and thermal expansion.
A comprehensive analysis of global sea level rise spanning from 1960 to 2023 has been published, offering a detailed breakdown of the sources driving the increase. The study, conducted by an international team of researchers, found that the rate of sea level rise has accelerated significantly in the past decade.
According to the research, the average annual rise in sea levels from 2014 to 2023 was twice that of the period from 1993 to 2003. The acceleration is attributed primarily to increased melting of ice sheets in Greenland and Antarctica, as well as the thermal expansion of ocean waters as they absorb heat.
The study utilized satellite altimetry data and in-situ measurements to track changes in ocean mass and volume. Scientists were able to isolate contributions from glaciers, ice sheets, and terrestrial water storage. The findings indicate that ice sheet loss has become the dominant driver of sea level rise in recent years.
Thermal expansion, which occurs as seawater warms and expands, accounted for about 40% of the observed sea level rise over the entire study period. However, its contribution has been outpaced by meltwater from ice sheets, which now contributes more than half of the annual increase.
The researchers emphasized that the acceleration in sea level rise poses significant risks to coastal communities worldwide. Even small increases can exacerbate storm surges, erosion, and flooding. The study projects that without substantial reductions in greenhouse gas emissions, the rate of rise will continue to accelerate.
Data from the study shows that global mean sea level rose by approximately 0.2 meters (7.9 inches) between 1960 and 2023. The rate of rise increased from about 1.4 millimeters per year in the 1960s to over 4.5 millimeters per year in the 2020s.
The findings were published in the journal Nature Climate Change. The authors call for improved monitoring and modeling to better predict future sea level changes and inform adaptation strategies.
