本月早些时候,拉斯维加斯出现华氏120度的历史高温,而美国东海岸沿岸地区目前也发出超高温预警,但周日,费城国际机场(Philadelphia International Airport)却罕见地出现降雪,创历史记录。
更不可思议的是,当天费城气温为华氏94度。
一场雷暴席卷全城,下起了小型冰雹,当时便发生了“非常”小规模的暴风雪。按照气象学的标准,这属于微量降雪,但这足以创造历史记录。
这种情况极其罕见,但并非史无前例。上一次发生这种情况是在2011年8月,当时曾出现过两次微量降雪(8月1日和18日)。2008年、2006年和1998年也出现过类似天气。将周日的降雪计算在内,费城机场在夏季月份共经历过14次微量降雪。
周日的降雪打破了1870年创下的历史记录。
虽然微量降雪不足以堆雪人或者滑雪,但在今年夏天全美大多数地区陷入超高温天气的情况下,这次微量降雪算是一次奢侈的喘息之机。酷热的夏天是致命的,根据美国疾病预防控制中心(Centers for Disease Control and Prevention)的数据,死亡人数可能超过去年夏天死于超高温的2,300多人。
面对2024年夏季的高温,美国疾控中心推出了一款工具,提醒民众接触高温的危险。民众通过这款高温风险(HeatRisk)地图,可以轻松查看健康风险。这个地图尤其对老年人或哮喘等疾病的患者大有帮助,对孕妇和儿童同样有用。
高温被归咎于气候变化,有科学家表示,再过四年,地球气温就会超过2015年《巴黎气候协定》中提出的1.5摄氏度(华氏2.7度)温升目标。(财富中文网)

Las Vegas hit record highs of 120 degrees earlier this month and areas along the East Coast are currently under extreme heat warnings, but at Philadelphia International Airport on Sunday, there was record snowfall.
What’s even more amazing is temperatures in the city hit 94 degrees that day.
The (very) mini blizzard occurred when a thunderstorm blew through town, producing small hail. In meteorological terms, that counts as a trace of snow—and a trace was enough to set a record.
It’s a rare event, but hardly an unprecedented one. The last time it happened was in August of 2011, when traces of snow were recorded on two separate occasions (Aug. 1 and 18). It also has occurred in 2008, 2006, and 1998. Counting Sunday, trace amounts of snow have been recorded 14 times in the summer months at Philly’s airport.
Sunday’s snowfall broke a record set in 1870.
While a trace isn’t enough to make a snowman or to pull out the skis, it’s a tony respite given the extreme heat that much of the country is facing this summer. The dangerously hot summer has been fatal and the number of deaths could top the over 2,300 people who died of excessive heat last summer, according to the Centers for Disease Control and Prevention.
The summer of 2024 has been so hot that the CDC set up a tool to warn people about the dangers of approaching heat waves. The HeatRisk map lets people easily see their risk for health issues, which can be especially useful for elderly citizens or those who have conditions such as asthma. It’s also useful for pregnant women and young children.
The heat has been blamed on climate change, with scientists saying Earth is four years away from crossing the 1.5 Celsius (2.7 Fahrenheit) target set in the landmark Paris climate accord of 2015.
