a very likely range (5-95% confidence level) of ), while the "moderate" SSP2-4.5 scenario adds with a likely and very likely range of and , respectively. The scenario which largely fulfils the Paris Agreement goals, SSP1-2.6, adds around and no more than , with a small chance of the ice sheet gaining mass and thus reducing the sea levels by around . For comparison, Greenland Ice Sheet is estimated to have contributed about 0.68 mm per year between 2012 and 2017, which is already a significant acceleration from the 1990s, when it contributed 0.07 mm per year between 1992 and 1997. This net contribution for the 2012–2016 period was also equivalent to 37% of sea level rise from land ice sources (excluding thermal expansion). Moreover, this contribution is disproportionately shaped by the most remote and vulnerable parts of the ice sheet such as its largest outlet glaciers, Jakobshavn Isbræ and Kangerlussuaq Glacier. Northeast Greenland Ice Stream is another relatively small area with a disproportionate impact on sea level rise: it was estimated in 2022 to contribute 1.3-1.5cm by 2100 all on its own under RCP 4.5 and RCP 8.5, respectively. However, while the ice sheet's massive size makes it insensitive to temperature changes in the short run, it also commits it to enormous changes down the line. The most vulnerable parts of the ice sheet which currently have a disproportionate contribution to its melt are already known to be beyond "a point of no return", with some estimates suggesting that they passed it around 1997, and will be committed to disappearance even if the temperature stops rising. A 2022 paper found that the 2000–2019 climate would already result in the loss of ~3.3% volume of the entire ice sheet in the future, committing it to an eventual of SLR, independent of any future temperature change. They have additionally estimated that if the then-record melting seen on the ice sheet in 2012 were to become its new normal, then the ice sheet would be committed to around SLR. Many scientists who study the ice losses in Greenland consider that an increase in temperature of two or three degrees Celsius would result in a complete melting of Greenland's ice.If the entire of ice were to melt, global sea levels would rise . Recently, fears have grown that continued climate change will make the Greenland Ice Sheet cross a threshold where long-term melting
