The average temperature of the world's oceans reached the highest point on record last year.
The Guardian reports that it's a sign of global warming and that studies show the oceans are getting warmer every year.
According to a recent report in the journal 'Advances In Atmospheric Sciences', the amount of heat added to the oceans is equivalent to every person on the planet running 100 microwave ovens 24/7.
The researcher warns that warmer oceans could lead to more severe floods, droughts and wildfires.
They also claim sea levels will rise by one meter by the end of the century at the current rate, potentially displacing 150 million people worldwide.
