Why did the number of sea turtles decrease due to global warming?

Hotter sand from increasing temps results in decreased hatching rates or nest failure. High sand temps also affect hatchlings by altering natural sex ratios, with hotter temps producing more female hatchlings. Sea turtles use ocean currents to travel and find prey. Warming ocean temps influence migratory species by altering currents and impacting the distribution and abundance of prey species.
