The research suggests the critical threshold for the Greenland ice sheet is between 1.7 and 2.3 degrees C of global warming. Bochow said humanity would have 100 years — perhaps more — to cool ...

Greenland's climate is a tundra climate (Köppen ET) on and near the coasts and an ice cap climate (Köppen EF) in inland areas. It ...
Consequently, its melting has a significant impact on a global scale. According to the European Environmental Agency "the cumulative ice loss from Greenland from 1992 to 2015 was 3 600 Gt (Gigatonnes) and contributed to global sea level rise by approximately 10 mm." [ 13 ] The mass loss of Greenland over 2009-2018 was likely more than seven ...
The biggest changes occurred during 2012 and 2019, when temperatures were extremely hot. The measurements were recorded using the agencies’ ice satellite missions: CryoSat-2 and ICESat-2.
By the end of the century, the melting of Greenland alone will add between ~6 cm (2 + 1 ⁄ 2 in) if the temperature change is kept below 2 °C (3.6 °F), to around 13 cm (5 in) if the most intense climate change scenario with ever-increasing greenhouse gas emissions is followed.
Greenland's ice melt is of particular concern, as the ancient ice sheet holds enough water to raise sea levels by at least 20 feet (6 meters) if it were to melt away entirely.
A 2021 analysis of sub-glacial sediment at the bottom of a 1.4 kilometres (0.87 mi) Greenland ice core finds that the Greenland ice sheet melted away at least once during the last million years, and therefore strongly suggests that its tipping point is below the 2.5 °C (4.5 °F) maximum temperature increase over the preindustrial conditions ...
Greenland from 2017 to 2020 averaged about 283 billion tons (257 billion metric tons) of melting a year, compared to just 235 billion tons (213 billion metric tons) annually from 2012 to 2016.
