自1970年代以来,由于气候变化,美国下降的气温上升了近2°F,使季节越来越温和、更短。 U.S. fall temperatures have risen nearly 2°F since the 1970s due to climate change, making seasons milder and shorter.

一项新的研究表明,全美国秋季的气温正在上升,近年来秋天季节越来越温和,越来越短。 A new study reveals that autumn temperatures across the U.S. are rising, with fall seasons becoming milder and shorter in recent years. 研究人员将这一变化归因于气候变化,并指出,自1970年代以来,平均降温上升了近2摄氏华氏度。 Researchers attribute the shift to climate change, noting that average fall temperatures have increased by nearly 2 degrees Fahrenheit since the 1970s. 调查结果表明,传统的秋天天气模式——酷日、寒冷空气和早期霜冻——越来越不常见,影响到农业、野生生物和季节性活动。 The findings suggest that traditional fall weather patterns—cooler days, crisp air, and early frosts—are becoming less common, affecting agriculture, wildlife, and seasonal activities.
