NASA: 2024 Sea Level Rise Exceeds Expectations, Climate Change a Major Culprit

NASA's latest analysis reveals that 2024 saw a far greater-than-expected sea level rise of 0.23 inches, surpassing the predicted 0.17 inches. This is primarily attributed to thermal expansion of ocean water due to global warming. Melting land-based ice also contributed. Interestingly, in 2024, thermal expansion accounted for two-thirds of the rise, while ice melt contributed one-third, a reversal of previous trends. The rate of annual sea level rise has more than doubled since 1993, with sea levels rising at least 4 inches since then. Since 1880, sea levels have risen between 8 and 9 inches. Human-induced climate change is the primary driver of current sea level rise.
