The Warming Earth - Why are some years still cooler than the year before?
The Earth is a very complicated planet. Where does the heat of global warming go? Heat can affect things without causing a temperature rise. Extra heat can be used in ‘changing state’ instead of raising temperature.
A change of state could be … a solid melting to a liquid.
Or a liquid evaporating to a gas.
So heat is needed to change ice at zero degrees C to water at zero degrees C.
And to change water into water vapour….. without raising the temperature.
