The official thermometer at Sydney is located immediately adjacent to 22 lanes of asphalt, and across the street from a glass building which reflects sunlight down on to the thermometer.
The thermometer shows rapid warming over the past twenty years.
But the thermometer in Sydney Harbour shows no warming over the past 20 years.
And no change in sea level for 140 years at Sydney Harbour.
There can be little doubt we need massive taxation and loss of freedom to reverse the zero-trend lines.
