The Human Impacts Database

A collection of useful numbers for quantifying the impacts of the human presence on Earth.

This quantity is a single measurement of the quantity at a given point in time (1993 — 2018).


Value:		3.4 (-0.44, + 0.47) × 10^-3 m / yr see this value in other units This is equivalent to... 3.4 (-0.44, + 0.47) mm / yr
HuID:		81373
Relevant Year(s):		1993 — 2018
Summary:		The observed global mean sea level rise annually for the time period 1993-2018. This value corresponds to the direct observed value and includes sources both known and unknown. Contributions due to thermal expansion of water, terrestrial water storage, and ice-water sum to the observed value within ≈ 0.2 mm.
Method:		See Table 1 of the source for more information. The uncertainty represents a 90% confidence interval.
