cooling off period

A new study by three economists has found hotter temperatures lead to less sex. Stop climate change; get laid more.

Although it’s not quite as simple as that, as the economists explain in their paper “Maybe next month? Temperature shocks, climate change and dynamic adjustments in birth rates” published this week by the prestigious National Bureau of Economic Research in the US.

Indeed, for any given month, additional days above 27 degrees were found to cause a large decline in birth rates about eight to 10 months later. While there was a rebound in subsequent months, this did not make up entirely for the decline.

The lack of a full rebound suggests that increased temperatures due to climate change may reduce population growth rates in the coming century.
