Since 1993, satellite-based instruments have been collecting data that scientists use to determine sea levels. This data shows that the average global sea level rose by about 3 inches over the past quarter century. Tide gauges indicate that sea levels have been generally rising since 1860 or earlier, or about 75 years before man-made emissions of CO2 reached 1% of natural emissions.
