NASA has announced an alarming acceleration in global sea levels in 2024, with a rise of 0.59 centimeters per year, higher than the anticipated 0.43 centimeters. This increase is attributed to the warming of ocean water, expansion due to heat, and melting glaciers. 2024 also marked the warmest year on record, with Earth’s oceans reaching their highest levels in three decades.

• Global sea levels rose 0.59 cm per year in 2024, faster than the expected 0.43 cm.
• Thermal expansion was responsible for two-thirds of the rise, replacing melting ice as the dominant factor.
• Warming ocean water is causing expansion and contributing to the rise in sea levels.
• Additional meltwater from glaciers and ice sheets is also accelerating sea level rise.
• 2024 marked the warmest year on record, contributing to rising ocean levels.
• Oceans reached their highest levels in three decades in 2024.
• Global sea levels have risen by 10 cm since 1993, according to satellite data.
• The rate of sea level rise has more than doubled since measurements began in 1993.
• NASA’s Jet Propulsion Laboratory warns the trend is accelerating, with rising seas expected to continue.
