Across much of the United States, a warming climate has advanced the arrival of spring. This year is no exception. In parts of the Southeast, spring has arrived weeks earlier than normal and may turn out to be the warmest spring on record. 美国大部分地区，气候变暖已导致春季提前到来，今年也不例外。东南部分地区，春天提前了几周，可能会成为史上最温暖的春季。 Apple blossoms in March and an earlier start to picnic season may seem harmless and even welcome. But the early arrival of springtime warmth has many downsides for the natural world and for humans. 三月份苹果树开花，野餐季节提前开始，这些看起来好像不是什么坏事，人们甚至还挺开心。但春季提前转暖对自然界和人类有很多不利之处。 Rising temperatures in the springtime signal plants and animals to come alive. Across the United States and worldwide, climate change is steadily disrupting the arrival and interactions of leaf buds, cherry blossoms, insects and more. 春季气温升高，动植物会苏醒。在美国和全世界范围内，气候变化不断扰乱发芽、樱花、昆虫等的出现和活动。 Records managed by the USA National Phenology Network and other organizations prove that spring has accelerated over the long term. For example, the common yellow trout lily blooms nearly a week earlier in the Appalachian Mountain region than it did 100 years ago. |
