A study indicates that by the end of the century, the world could experience nearly two additional months of extremely hot days annually, disproportionately affecting poorer nations compared to major carbon emitters. The Paris climate agreement has mitigated some of this impact, potentially reducing the number of superhot days. The report highlights the unequal distribution of climate change effects, with small island nations facing the brunt of the heat, while larger polluters like the US, China, and India will see fewer additional hot days. The findings underscore the ongoing challenges of climate change and its implications for global inequality.
