Is sea level rise exaggerated?

Sea levels are rising at an accelerating rate, not stagnating or decreasing.

Warming global temperatures cause land ice to melt and oceans to thermally expand, elevating sea levels. Since 1880, they’ve risen an estimated 8-9 inches (over 20 cm) based on historical data from coastal tide gauge stations.

In the 1990s, scientists began using satellites to measure sea levels. Since 1993, the global average sea level has risen 4 inches (10 cm).

These satellites send pulses to the ocean and measure the time it takes for the signal to return. Researchers account for factors like land height, resulting in highly accurate measurements with error margins of 1 millimeter. Short-term dips don’t contradict the overall rise, which is exceeding prior predictions.

Sea level rise has already submerged islands and atolls in places like The Solomon Islands and The Marshall Islands, while coasts worldwide have experienced flooding, infrastructure damage, and land loss.
