The bad news is that increased sand temperatures are detrimental to all hatchlings...
Sea Turtle Hatchlings Dying in Extreme Heat On a related note, turtle hatchlings were found dying in extreme heat on Queensland's famous Mon Repos beach where a heatwave pushed the sand’s temperature to a record 75 degrees Celsius (167 degrees Farenheit).
