The Human Impacts Database

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

This quantity comes from a time series measurement and the most recent value (2002-2021) is reported.


Value:		-(5.122 ± 0.051) × 10¹⁵ kg see this value in other units This is equivalent to... -5122 ± 51 Gt -(5.567 ± 0.055) × 10¹² m³ ice
HuID:		44746
Relevant Year(s):		2002-2021
Summary:		The reported value represents the mass lost from the Greenland Ice Sheet since 2002.The dataset is current as of December 2021 yet is subject to change as it continues to be updated. Data can be accessed after registering for a free Earthdata account.
Method:		Estimates of ice sheet mass loss are derived from satellite gravimetric observations taken by NASA's Gravity Recovery and Climate Experiment (GRACE) and GRACE Follow-On (GRACE-FO) satellites. The gap in 2017 and 2018 represents the time between the GRACE and GRACE-FO missions. The uncertainty is calculated at a 1-sigma uncertainty level. Ice volume loss was calculated from ice mass loss assuming a standard pure ice density of 920 kg / m³.
