the past 150 years or so, it is expected to tilt heavily toward female offspring over this century from about 70 percent female and 30 percent male on the lighter colored beaches today to 90 percent female and 10 percent male by 2100. And that's for an emissions scenario that assumes the world gets aggressive about slowing the release of greenhouse gases into the atmosphere. Under scenarios that assume "business as usual" emissions levels more like today's, the sex ratio tips even further in the females' favor, to about 97 percent female and 3 percent male.

According to a new study published Monday in the scientific journal Nature Climate Change, warmer climates will likely trigger an explosion in the number of female sea turtle hatchlings born annually, and an equally dramatic decline in the number of males born each year. That's because temperature plays a critical role in determining the sex of turtle hatchlings during their incubation period. Warmer temperatures above a pivotal threshold typically about 84F while they're developing mean hatchlings are more likely to be born female. Below that, they're more likely to be more male. To test their hypothesis, the researchers in the study collected air and sand temperature data from the beaches of an island called Sal, one of the Cape Verde Islands in the North Atlantic Ocean, located just over 400 miles off the coast of Senegal in West Africa.

"To date, our March temperatures continue at greater than 2 degr.

That's because males mate more often than females, and because females can store sperm, which allows them to fertilize several clutches, or groups of hatchlings. But in the long term, consequences related to climate change like rising sea levels swallowing up and eroding away the beaches where turtles nest could "push local turtle populations over the brink unless new suitable nesting beaches are found," they wrote in the report. "As remaining males die off, 'it'll be end of story without human intervention. '"There's no arguing we've had a remarkably warm winter. Looking back, the west coast hasn't had a typical winter for six years.

There, they studied beaches with both lighter colored and darker colored sand, the latter of which are typically warmer (their darker color absorbs more of the sun's rays) and produce a greater percentage of female hatchlings than their lighter colored counterparts. What they found was that while there hasn't been a clear upward or downward trend in the ratio of female vs. male offspring over Nike Dunks Black
