Heat waves over the ocean have ballooned and are wreaking havoc on marine life

Heat waves over the world’s oceans are becoming longer and more frequent, damaging coral reefs and creating chaos for aquatic species. A study published Tuesday in the journal Nature Communications found a 54 percent increase in the number of days in which heat waves have cooked the oceans since 1925.

The rise in these marine heat waves has occurred while ever more heat is stored in the ocean because of accumulating greenhouse gases in the atmosphere. The ocean heat content in 2017 was the highest in recorded history, noted Kevin Trenberth, a climate scientist at the National Center for Atmospheric Research. Trenberth said in an email that ocean heat waves will necessarily increase given the building stockpile of heat, which has been measured from the surface down to more than a mile deep (2,000 meters).
