Mass loss from the ice sheets in Greenland and Antarctica has quadrupled since the 1990s and they now represent the dominant source of sea-level rise, with potential to add over 15 m by 2300. This has focused attention on the temperature thresholds that might trigger their irreversible retreat and prompted urgent calls to meet the more ambitious target of the Paris Agreement and limit warming to 1.5 °C. This event will summarize the latest science, much of it post IPCC AR6, to highlight the worrying changes already taking place and the clear risks of exceeding 1.5°C.
