It's ok, did he not see the current mass balance, which has been tracking well above the long-term average?

Why would you use the Surface mass balance? That specifically excludes calving and ice lost through contact with water.
The actual mass lost in Greenland is here

This is a previous graph I had showing the response of Greenland discharge per year to the change in the AMO.
This paper also shows a strong correlation with the AMO and Greenland Blocking Index.
Correlation analysis of Greenland coastal weather station temperatures against the North Atlantic Oscillation (NAO) and the Atlantic Multidecadal Oscillation (AMO) indices for the summer season (when Ice Sheet melt and runoff occur) reveals significant temporal variations over the last 100 years, with periods of strongest correlations in the early twentieth century and during recent decades. During the mid-twentieth century, temperature changes at the stations are not significantly correlated with these circulation indices. Greenland coastal summer temperatures and Greenland Ice Sheet (GrIS) runoff since the 1970s are more strongly correlated with the Greenland Blocking Index (GBI) than with the NAO Index (NAOI), making the GBI a potentially useful predictor of ice-sheet mass balance changes. Our results show that the changing strength of NAOI–temperature relationships found in boreal winter also extends to summer over Greenland. Greenland temperatures and GrIS runoff over the last 30–40 years are significantly correlated with AMO variations, although they are more strongly correlated with GBI changes. GrIS melt extent is less significantly correlated with atmospheric and oceanic index changes than runoff, which we attribute to the latter being a more quantitative index of Ice Sheet response to climate change. Moreover, the four recent warm summers of 2007–2010 are characterised by unprecedented high pressure (since at least 1948—the start of the NCEP/NCAR reanalysis record) in the tropospheric column. Our results suggest complex and changing atmospheric forcing conditions that are not well captured using the NAO alone, and support theories of an oceanic influence on the recent increases in Greenland temperatures and GrIS runoff.

An acceleration over the past 5 years? How do you make that out? The only data source I can find on that site is a screenshot of the video graph. But here's the 2021 annual report too, and in both I fail to see any acceleration in the past five years, only a continuation of the previous trend, but maybe I'm just blind.
Greenland ice sheet total mass change for 1 September 2020 to 31 August 2021 was -85 ± 16 Gt, 179 Gt less than the 2002-21 average of -264 ± 12 Gt yr-1.

More climate propaganda from RTÉ on Morning Ireland this morning (podcase below), claiming that the drought in the Horn of Africa is all attributed to climate change.
Four failed rainy seasons have resulted in the worst drought in forty years, and that's all attributed to climate change.
This level of blatant unchallenged misinformation has become par for the course now. Any climate scientist worth their salt would pull them up on this and highlight that La Nina with a negative Indian Ocean Dipole has always been known as the No. 1 driver of droughts in that region, with major droughts (1973-74, 1984, 2011, now 2022) all coinciding with this 100% natural phenomenon. Of course, Sweeney, Thorne, etc., wouldn't dare upset the apple cart with such factual reasoning, but are quick to get on air when we get e.g. a regular winter storm.

The main driving factors for the increased occurrence of drought in the GHA are natural climate variability and anthropogenic influences (Dinku et al., 2011, Funk et al., 2015, IPCC, 2013, Trenberth et al., 2014). The climate system over the GHA is inherently variable with complex topographies ranging from arid lowlands to wetter highlands and coastal areas (Dinku et al., 2011, Funk et al., 2015, Schreck and Semazzi, 2004). The major climatic factor influencing droughts is the seasonal dynamics of tropical circulations expressed as the El Niño Southern Oscillation (Ogallo et al., 2008). The influence of El Niño (the warm phase) and La Niña (the cold phase) of the El Niño Southern Oscillation shows an increased climate variability in the GHA.

Beyond climate variabilities, anthropogenic factors such as deforestation, land-use changes, land degradation, and excessive use and poor management of natural resources have contributed to the occurrence and intensity of drought in the GHA (IPCC, 2013, Lyon, 2014, Trenberth et al., 2014). Therefore, the interacting impacts of climate and human activities on the environment have made drought more frequent, longer, and more intense in the GHA

On the Greenland Ice Sheet mass-loss and the zoomed-in graphs that show hundreds of GT loss per year, the graph below is what the actual effect is on the total mass. The GIS has a total volume of around 2.85 million km^3, which is around 2.61 million GT of ice. With an average loss of 280 GT/yr since 2002, the total loss up to 2021 is around 0.2% of the total mass, or around 0.01% per year.
