The projected temperature increases pose significant risks to ecosystems, human health, and global stability. Crossing the 1.5°C threshold could lead to more frequent and severe extreme weather events, including heatwaves, droughts, and floods. Vulnerable ecosystems, such as coral reefs and glaciers, may face irreversible damage. The Amazon's shift from a carbon sink to a carbon source could accelerate climate change, while increased rainfall in the Sahel could lead to devastating floods. The Arctic's warming will contribute to rising sea levels and threaten species dependent on sea ice. These changes are expected to result in higher mortality rates, food insecurity, and economic instability worldwide.
