Glaciers in the Russian High Arctic have been subject to extensive atmospheric warming due to global climate change, yet their contribution to sea level rise has been relatively small over the past decades. Here we show surface elevation change measurements and geodetic mass balances of 93 % of all glacierized areas of Novaya Zemlya, Severnaya Zemlya, and Franz Josef Land using interferometric synthetic aperture radar measurements taken between 2010 and 2017. We calculate an overall mass loss rate of <math xmlns="http://www.w3.org/1998/Math/MathML" id="M1" display="inline" overflow="scroll" dspmath="mathml"><mrow><mo>-</mo><mn mathvariant="normal">22</mn><mo>±</mo><mn mathvariant="normal">6</mn></mrow></math> <svg:svg xmlns:svg="http://www.w3.org/2000/svg" width="39pt" height="10pt" class="svg-formula" dspmath="mathimg" md5hash="4b9e18a184893d4f6b000b93b280a068"><svg:image xmlns:xlink="http://www.w3.org/1999/xlink" xlink:href="tc-16-35-2022-ie00001.svg" width="39pt" height="10pt" src="tc-16-35-2022-ie00001.png"/></svg:svg> Gt a −1 , corresponding to a sea level rise contribution of 0.06±0.02 mm a −1 . Compared to measurements prior to 2010, mass loss of glaciers on the Russian archipelagos has doubled in recent years.
