Exposure, vulnerability, land management, and natural variability also shape disaster losses. Newer evidence strengthens some conclusions without making every event attributable.",

Comparing SREX with AR6 and the Fifth National Climate Assessment shows both the strengthened findings and the remaining limits.",
