Ice loss from the Greenland and Antarctic Ice Sheets has quadrupled since the 1990s and now represents the dominant source of sea-level rise, with potential to add over 15 meters by 2300. Rising global temperatures are approaching thresholds that can trigger irreversible retreat, prompting urgent calls to meet the more ambitious target of the Paris Agreement and limit warming to 1.5°C. Dr. Chris Stokes from Durham University summarized 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. Note: some portions of this on-site video have competing noise, but turning on closed captions (button in the bottom right corner) can help.
