Global sea levels rose at an alarming rate in 2024 surpassing previous predictions due to an unusual spike in ocean warming and melting land-based ice. According to a NASA led analysis the rate of rise last year was 0.23 inches (0.59 cm) per year, significantly higher than the expected 0.17 inches (0.43 cm) per year. Scientists attribute this sharp increase primarily to the thermal expansion of seawater process where ocean water expands as it warms. In a surprising shift, two-thirds of last year’s sea level rise came from thermal expansion reversing the usual trend where melting glaciers and ice sheets were the dominant contributors. Josh Willis sea level researcher at NASA Jet Propulsion Laboratory in Southern California say “The rise we saw in 2024 was higher than we expected, Ever...

A new study warns that global sea levels could rise as much as 1.9 meters by 2100 if carbon emissions remain unchecked 90 centimeters higher than the latest estimates by the UN’s Intergovernmental Panel on Climate Change (IPCC). The research, conducted by scientists at Nanyang Technological University (NTU) in Singapore and Delft University of Technology (TU Delft) in the Netherlands, introduces a more accurate projection method that accounts for extreme climate scenarios. Published in Earth Future, the study highlights that traditional sea-level rise estimates vary widely due to uncertainties in climate models. While most models include well-understood factors like glacier melt, they struggle to predict less certain events such as sudden ice shelf collapse. To address this, the researc...
