Thermal conductivity of water increasing with temperature

[gfd43tg]

The thermal conductivity of most solids and liquids decreases with increasing temperature, but water is an anomaly because it actually increases with increasing temperature. I don't understand why though. I suppose it is something about the material itself and its hydrogen bonding, but not sure why it is like this.

Liquids should transfer heat from collisions, and I don't see why water would be any different.

I was under the impression that most metals have an increase in thermal conductivity with an increase in temperature.
