The IPCC introduced the idea of tipping points two decades ago. A possible tipping point is the melting of land ice in the polar regions (Greenland and Antarctica), leading to many meters of sea-level rise over time. Models suggest that the Greenland ice sheet could eventually disappear at 1.5 °C of warming[1]], although only after many years. In July 2021, a heat wave caused Greenland to lose enough ice to cover the US state of Florida in 2 inches (5cm) of water in one day[2] [3]. Sea ice is already shrinking rapidly in the Arctic, indicating that, at 2°C of warming, the region has a 10–35 percent chance of becoming largely ice-free in the summer[4].
