Warm, dry El Nino weather puts baby sea turtle at risk

Climate variability associated with El Nino was associated with higher mortality for eggs and hatchlings of the critically endangered leatherback turtle, an effect that could be worsened by continuing global climate change, according to research published May 23 in the open access journal PLoS ONE.

The El Nino Southern Oscillation brought dryer, warmer conditions to northwest Costa Rica, one of the major nesting sites in the area. The researchers, led by Pilar Tomillo of Drexel University in Philadelphia, found that these weather conditions were associated with increased egg and hatchling mortality.

Furthermore, climate models project that such conditions will become more common in the region over the next hundred years, which could significantly impact the already threatened leatherback turtle population.
