Which sentence describes an example of a positive feedback loop? Warm-blooded animals sweat when they get too hot. Sweating is a method by which the body cools itself. A thermostat regulates temperature by turning a furnace or air conditioner on and off. When blood flows from a mild cut, blood clots form to prevent excessive bleeding. As oceans get hotter, they release more CO2, which then increases atmospheric and ocean temperatures.

The correct answer is As oceans get hotter, they release more CO2, which then increases atmospheric and ocean temperatures.

Positive feedback is a process which can be explained like this: A produces more of B which in turn produces more of A. In the example above, high-temperature oceans (A) produce CO2 (B) which then make temperature even higher (A).
