Surge in Sea Level Rise Linked to Record Heat in 2024

In 2024, global sea levels rose at an accelerated rate of 0.23 inches (0.59 centimeters) per year, surpassing the expected 0.17 inches (0.43 centimeters), an article by Earth.com claimed. This increase is primarily attributed to thermal expansion, which now accounts for two-thirds of the rise, as oceans absorb heat from climate change.

With 2024 marking the warmest year on record, the oceans have reached their highest levels in three decades. Satellite data, collected since 1993, shows a consistent upward trend, with sea levels climbing approximately 4 inches (10 centimeters) since the early 1990s.

This rise poses significant risks to coastal cities, leading to stronger storm surges, flooding, and erosion. Scientists emphasize the need for enhanced defenses, including sea walls and improved drainage systems, to mitigate the impact of rising waters. The ongoing monitoring of sea levels is crucial for understanding and addressing future climate challenges.
