The projected warming poses significant risks to ecosystems and human populations. In the Arctic, rising temperatures threaten wildlife and accelerate ice melt, contributing to sea level rise. The Amazon basin is expected to experience drier and hotter conditions, increasing the risk of wildfires and endangering biodiversity. Globally, surpassing the 1.5°C threshold could lead to more extreme weather events, including heatwaves, droughts, and heavy rainfall. The rapid warming rate—0.45°F (0.25°C) per decade—exceeds historical trends, underscoring the urgency of climate mitigation efforts.
