Two UN reports warned that exceeding the 1.5°C global-warming threshold above pre-industrial levels would have major consequences—some irreversible—for glaciers, sea ice and permafrost, while increasing the risks of flooding, water shortages, and economic and environmental losses. If warming reaches 2.8°C and persists through the next century, sea levels could rise by as much as 5 centimeters a year by 2150, compared with about 0.45 centimeters today. The UN said the world is no longer on track to meet the 1.5°C goal, while scientists called for cuts to fossil-fuel emissions, a shorter period of overshoot, and a return to below the threshold as quickly as possible.
