The report warns of severe consequences if global temperatures continue to rise, including more frequent and intense heatwaves, destructive floods, failed harvests, and loss of life, particularly in vulnerable regions like Africa. An additional tenth of a degree of warming could push 140 million people into dangerously hot conditions and increase the risk of ecosystem collapse, such as the Amazon rainforest and polar ice sheets. Economic impacts are also significant, with an estimated $1.2 trillion loss to the global economy. The U.S.'s retreat from climate commitments may further discourage other nations from taking necessary actions, exacerbating the crisis.
