From CBS News:
Climate change could affect the ratio of human males to human females that are born in some countries, a new study from Japan suggests. The researchers found that male fetuses may be particularly vulnerable to the effects of climate change.How in the hell does he know that? Of course there has been an 18 year pause in global warming.
Since the 1970s, temperature fluctuations from the norm have become more common in Japan, and at the same time there has been an increase in the deaths of male fetuses, relative to the number of deaths of female fetuses in that country, according to the study.
Over this period, the ratio of male to female babies born in the country has been decreasing, meaning there have been fewer and fewer male babies born relative to the number of female babies born.
This suggests that climate warming or climate extremes could negatively affect male fetuses, study researcher Dr. Misao Fukuda, of M&K Health Institute in Ako, Japan, told Live Science in an email.
Oh, then there is this bit. From the same article:
However, the new study only found an association, and cannot prove that the climate changes were responsible for the change in sex ratio in Japan. Other factors, such as pollution and toxins in the environment, may affect sex ratios. But the researchers noted that the study found a link between temperatures in a specific month, and the sex ratios nine months later, suggesting temperature fluctuations may play a role in recent declines in the country's sex ratio.Related posts:
