Global warming poses one of the greatest threats to humanity. Flash floods, droughts, super typhoons—there's basically no limit to the disasters it can bring about. Now a new possible catastrophe can be added to the list: low sex drive.
A study titled "Maybe Next Month? Temperature Shocks, Climate Change, and Dynamic Adjustments in Birth Rates" published by the National Bureau of Economic Research suggests that, as worldwide temperature increases, people feel less inclined to go between the sheets. Or as the report puts it, the "coital frequency" diminishes.

The research reveals that from 1931 to 2010 there were about 1,165 fewer births nine months after days when it was over 80-degrees Fahrenheit (27-degrees Celsius)—a 0.4 percent decrease in birth rates. This apparently indicates that a rise in temperature reduces fertility, decreases appetite for intercourse, or quite possibly, both.
"It [temperature] could affect hormone levels and sex drives," said the study. "Alternatively, high temperatures may adversely affect reproductive health or semen quality on the male side, or ovulation on the female side."
The study also found out that people tend to make up for a lost day of sex when it cools down. However, it still isn't enough to augment the decreased in the number of births during the hot days.
Although the study only analyzes the data from the United States, the consequences are likely to be even more pronounced in the developing world.
Now excuse us while we prepare to move to the North Pole.
