New York, November 9: What has climate change to do with sex drive? A lot, say researchers, suggesting that global warming is not only hampering our environment and tural resources but also the action between the sheets. According to a study published by the US tiol Bureau of Economic Research, a non profit research organisation, climate change that is causing more hot days is bringing down the birth rate in the US.
To understand the impact of global warming on declining birth rates, the investigators estimated the effects of temperature shocks on birth rates in the US between 1931 and 2010.
The innovative approach allowed for presumably random variation in the distribution of daily temperatures to affect birth rates up to 24 months into the future. “We found that additiol days above 27 degrees Celsius caused a large decline in birth rates approximately eight to 10 months later,” the authors noted. The initial decline is followed by a partial rebound in births over the next few months, implying that populations can mitigate the fertility cost of temperature shocks by shifting conception month, the study observed. This dymic adjustment helps explain the observed decline in birth rates during the spring and subsequent increase during the summer. “The lack of a full rebound suggests that increased temperatures due to climate change may reduce population growth rates in the coming century,” the authors wrote. According to lead author Alan Barreca, associate professor of economics at Louisia-based Tulane University, he got interested in conducting the study after he started thinking about seasol patterns in birth rates. “I, like many people, was interested in why there are these peaks in birth rates — why most of my friends tend to be born in August or September,” Barreca told Mashable.com in a report. According to the study, as an added cost, climate change will shift even more births to the summer months when third trimester exposure to dangerously high temperatures increases. (IANS)
