GEOLOGY

Detailed explanation-1: -Over the past 100 years, global temperatures have risen about 1 degree C (1.8 degrees F), with sea level response to that warming totaling about 160 to 210 mm (with about half of that amount occurring since 1993), or about 6 to 8 inches.

Detailed explanation-2: -Today, global sea level is 5-8 inches (13-20 cm) higher on average than it was in 1900. Between 1900 and 2000, global sea level rose between 0.05 inches (1.2 millimeters) and 0.07 inches (1.7 millimeters) per year on average.

Detailed explanation-3: -Although the sea level has risen by 6.5 inches since 1950, nearly half of it (3 inches) has occurred in just the last 20 years. This small increase in sea level has caused on average a 233% increase in tidal flooding across the United States.

Detailed explanation-4: -As a consequence of global warming, albeit naturally, the rate of sea-level rise averaged  1.2 cm per year for 10, 000 years until it levelled off at roughly today’s position  10, 000 years ago.

Detailed explanation-5: -Globally, sea level has risen about eight inches since the beginning of the 20th century and more than two inches in the last 20 years alone.
