Global average sea level rose by about 0.3 inches (0.76 centimeters) from 2022 to 2023, a relatively large jump due mostly to a warming climate and the development of a strong El Niño.

Global average sea level has rison a total of about 4 inches (0.4 centimeters) since 1983. The rate of this increase has also accelerated, more than doubling from 0.07 inches (0.18 centimeters) per year in 1993 to the current rate of 0.17 inches (0.42 centimeters) per year.

It is also interesting to read how they came to these conclusions:

• long-term datasets (30 years of data and more)
• international cooperation
• technical innovation and progress
