Exceeding the 1.5°C limit could trigger irreversible climate tipping points, such as the loss of coral reefs, ice sheet retreat, and the transformation of the Amazon Rainforest into grasslands. These changes could lead to more extreme weather events, rising sea levels, and widespread ecological and economic disruptions. Vulnerable populations, particularly in developing nations, are expected to bear the brunt of these impacts, deepening global inequalities and resulting in significant loss of life and livelihoods.
