Peter Boyer is apparently a disciple of Al Gore – one of the many
who has been trained to give that famous slide show about the imminent
climate crisis. Anyway, he is also a columnist for The Mercury
– Rupert Murdoch’s newspapers in Tasmania. Today, in a piece entitled
‘Misleading opinion fed by misunderstood data’ he writes:
“Jennifer Marohasy told ABC Counterpoint listeners that NASA data
showed Earth's surface temperature was trending down from a high in
1998, revealing serious flaws in greenhouse theory.
If confidence and clear expression were all that counted in the
climate debate, Dr Marohasy would be a winner. Listeners unfamiliar
with the data she talked about may have felt she was right.
But alas, the evidence says otherwise.
Present and past global average surface temperatures are derived
from painstaking assessment of countless readings all over the planet,
on land and sea, together with satellite observations, corrected for
local aberrations such as the urban heat island effect.”
Accompanied by a graph showing the last 120 years temperature trend
Mr Boyer went on to suggest that the world is still warming.
Of course the world has been mostly warming over the last 120 years,
but over the last 10 years global temperatures have not been trending
up, as predicted by the United Nations Intergovernmental Panel on
Climate Change, despite a continual increase in carbon dioxide
emissions.
