Summary:

- The article discusses a study that found the Greenland ice sheet is likely to melt completely if global temperatures rise by more than 1.5°C above pre-industrial levels, even if temperatures then stabilize.
- The study used a new model that simulates the long-term response of the Greenland ice sheet to different levels of global warming, providing more specific information on the ice sheet's tipping point.
- The findings highlight the critical importance of limiting global temperature rise to meet the Paris Agreement goal of keeping warming well below 2°C, as the Greenland ice sheet is a major contributor to sea level rise with far-reaching consequences.
