We'll never get rid of these guys

 

In a La Nina, warm water sticks to a deeper depth, resulting in a cooler surface. And that reduces how much energy goes out into space, says study co-author Yu Kosaka, a climate scientist at the University of Tokyo.

That's 'sinks', and warm water never sinks below cold.  I could show that in the kitchen, but everybody is supposed to know this.  I feel sad for the world.
