Men, if you weren't concerned about climate change, you'd better be now!

...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.

The findings, published in the journal Fertility and Sterility—reveal that the proportion of male Japanese newborns has steadily declined since the 1970s. At the same time, the number of male "fetal deaths" during that general period—those that were spontaneously miscarried after 12 weeks of pregnancy—has increased. The researchers see a clear link to Japan's temperature fluctuations.

The team also picked out one very hot summer in 2010—Japan's warmest since 1898—and one very cold winter in 2011, and found similar trends linked to climactic extremes: more fetal deaths followed by a lower ratio of male to female newborns.

It's not an open and shut case. The researchers point out that climate change certainly isn't the only factor affecting the newborn gender ratio—and they stop short of arguing that there's a causal relationship between increased temperatures and more female offspring....

If true and I think that's a huge if, it can only mean one thing. Warming is good and the species is trying to increase population
