The overshoot of the 1.5°C threshold is likely to result in increased weather-related disasters, rising sea levels, and the extinction of species such as coral reefs. Vulnerable populations, particularly in poorer regions, will face heightened risks including food shortages, water scarcity, and health crises. The report also warns of potential tipping points, such as the loss of the West Antarctic and Greenland ice sheets, which could lead to irreversible damage. Some areas may become uninhabitable or uninsurable due to extreme climate conditions.
