加利福尼亚州圣芭芭拉大学、杜兰大学以及佛罗里达中部大学的学者分析了近80年来美国的生育情况与气温数据。统计发现气温升高之后的8-10月出生率有明显的下降。特别的是如果有超过80华氏度(约27摄氏度)的气温出现,其出生率会有较大程度的下降。气温下降之后的最初几个月内出生率会有部分反弹,这表明准父母们在弥补之前损失的时间,从而能在冷些的月份里怀孕——全球变暖会让这些事儿变得更加困难。然而,这
Scholars at Santa Barbara University in California, Tulane University, and Central Florida University analyzed fertility and temperature data in the United States in the past 80 years. Statistics show that there is a clear drop in the birth rate from August to October after the temperature rises. In particular, if there is a temperature of more than 80 degrees Fahrenheit (about 27 degrees Celsius), its birth rate will have a greater degree of decline. A partial rebound in birth rates during the first months after the temperature drop indicates how prospective parents are compensated for lost time so they can become pregnant in cooler months - global warming will make these things even more difficult . However, this
