It turns out that warming temperatures may have a surprising gender bias—in favor of women. That’s the conclusion of a team of Japanese researchers who have discovered a “statistically significant” association between climate change—including rising temperatures and extreme weather events—and the birth rates of boys and girls in Japan. Warmer temperatures have accompanied an increased proportion of female babies in the population, and a decline in males.
