Climate Change - Why isn't every year a record year?
Heat can affect things without causing a temperature rise.
Extra heat can be used in ‘
’ instead of raising temperature.
A change of state could be … a
melting to a
evaporating to a
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.
Scientists call the heat used to change state
Also, there are natural variations in the global climate,
events being the ones that affect world temperature the most.
The opposite to 'El Nino' is 'La Nina', a cooling effect.
If global temperatures are plotted on a graph in a way that shows these variations, it makes the overall warming trend very obvious.
Every La Nina year since 1998 has been warmer than every El Nino year before 1995.
As the Earth warms, each El Nino event 'rides' on a higher base-line global temperature:
