加拿大将气候归因扩大至极端雨, 发现气候变暖导致最近的暴雨可能性高达10倍。 Canada expands climate attribution to extreme rain, finding warming made recent downpours up to 10 times more likely.

加拿大环境和气候变化部正在扩大其快速的气候归属系统,最初用于极端热度,以评估气候变化如何影响极端降雨量。 Canada’s Environment and Climate Change department is expanding its rapid climate attribution system, originally for extreme heat, to assess how climate change affects extreme rainfall. 自2025年6月以来,它分析了42起重大降雨事件,发现由于全球变暖,大多数事件的可能性高达2倍,巴芬岛7月的三次大雨可能比6月大10倍。 Since June 2025, it has analyzed 42 major rain events, finding most were up to twice as likely due to global warming, with three—like a July downpour on Baffin Island—up to 10 times more probable. 该方案利用气候模型来比较工业前和目前的状况,目的是在公众关注高峰期间及时提供洞察力。 The program uses climate modeling to compare pre-industrial and current conditions, aiming to deliver timely insights during public attention peaks. 在不列颠哥伦比亚省南部面临来自大气河流的洪水时,这项努力变得更为紧迫,这与先前关于气候变化使公元前2021年成为公元前2021年的结论相呼应。 The effort gains urgency as southern British Columbia faces flooding from an atmospheric river, echoing prior findings that climate change made the 2021 B.C. 事件 60% 的可能性更大。 event 60% more likely. 该倡议支持应急规划和长期适应行动。 The initiative supports emergency planning and long-term adaptation.
