Blood vessels in the skin begin to dilate allowing more blood from the body core to flow to the surface of the skin allowing the heat to radiate into the environment. These nerve cells send messages to the brain, which in turn causes the pituitary gland at the base of the brain to release the hormone oxytocin into the bloodstream.

This is a positive feedback because much more solar energy is absorbed by the water than by the pre-existing ice, and the temperature increase is amplified.

These include changes in the radiation from the Sun, changes in the tilt of the Earth, changes in Earth's orbit, changes in greenhouse gas concentrations in the atmosphere, shifts in the location of land on earth through plate tectonics, and changes in ocean circulation.
