The report underscores the global risks associated with surpassing the 1.5°C warming limit, including accelerated melting of glaciers and ice sheets. This could lead to rising sea levels, threatening coastal communities and ecosystems. The loss of ice reserves would also disrupt freshwater supplies for millions of people who depend on glacial meltwater. Additionally, the cascading effects of such changes could intensify extreme weather events, such as floods and droughts, further endangering vulnerable populations and ecosystems.
