到2045年,气候变化威胁到全球马拉松的86%,气温不安全,敦促适应和紧急减排。 Climate change threatens 86% of global marathons by 2045 with unsafe temperatures, urging adaptation and urgent emissions cuts.

气候变化正在减少马拉松的理想天气,气候中心分析预测到2045年,全球221个马拉松中的86% — — 包括所有7个世界马拉松少校 — — 将面临最佳气温(39-50°F)的下降。 Climate change is reducing ideal weather for marathons, with a Climate Central analysis projecting that by 2045, 86% of 221 global marathons—including all seven World Marathon Majors—will face declining chances of optimal temperatures (39–50°F). 由人类活动驱动的全球气温不断上升,已经在东京和柏林等事件中将种族条件推到了安全限度之外。 Rising global temperatures, driven by human activity, have already pushed race conditions beyond safe limits in events like Tokyo and Berlin. 东京、波士顿和纽约等城市的精英男性选手,以及伦敦、纽约和柏林的精英女性选手,尽管妇女的热应力更强,但理想条件的几率将降低。 Elite male runners in cities like Tokyo, Boston, and New York, and elite female runners in London, New York, and Berlin, will see reduced odds of ideal conditions despite women’s greater heat resilience. 运动员必须调整培训和体液化战略,同时敦促组织者考虑较早的开始时间。 Athletes must adapt training and hydration strategies, while organizers are urged to consider earlier start times. 长期解决办法要求紧急采取全球行动,削减化石燃料的使用。 Long-term solutions require urgent global action to cut fossil fuel use.
