Doubling time is the amount of time it takes for a quantity to double in size (exponential growth). By 2020, there was enough data to see the doubling time of some anthropogenic climate affects had gone from 100 years to 10 years. For instance the rate of sea level rise has gone from about 1.5 millimeters per year to over 3 millimeters. We expect to see the doubling period to continue to shrink raising the possibility of sea levels rising a foot/year by 2050.
Global average sea level rose by about 0.3 inches (0.76 centimeters) from 2022 to 2023, according to a NASA-led analysis. When we authored this paper in 2023, we could not have foreseen the swift acceleration of this trend. Initially projected to double over a span of 100 years, the rate of sea level rise dramatically escalated, shortening the doubling period to a mere 10 years by 2020. Shockingly, recent observations suggest that this doubling period has further compressed to just 2 years. It is imperative to acknowledge and address this concerning trend, hoping it is not a foreboding indication of a new norm but rather an anomaly.
Sidd elaborated, “I suspect this is linked to the large jump in sea surface temperature last year, perhaps because of the restriction on sulfur in marine fuel. The top of the ocean warmed quickly and expanded. Let’s see if it is sustained.”
