Climate change academics “strike back”
Surfer
IN the midst of Copenhagen, the University of Western Australia (UWA)
hosted its own contentious event last week, exploring some of the
information, or �disinformation�, available on anthropogenic global
warming.
At the event, Shaping the Future of Climate Change: Dogma or Consensus
� Scepticism or Denial, Professor Malcolm McCulloch from ANU�s School
of Earth Sciences presented �The science and forensics of climate
change�.
Prof McCulloch, also the deputy director of the ARC Centre of
Excellence for Coral Reef Studies, says ice core records and the best
scientific data all reveal there is more CO2 in the atmosphere now,
than in the past million years.
�In the past 10,000 years, the ice core data shows the CO2 was sitting
around 280ppm. It did rise a little, up to about 290,� Prof McCulloch
says.
�In the most recent era, through industrialisation, we�re approaching
390ppm and we are on our way to 400.
�From about 1950 onwards is when the most rapid increases occurred.
�It�s not surprising that this is consistent with the burning of
energy, in particular coal, oil and gas. There�s a correlation between
energy use and the rise in CO2.
�This rapid rise is unprecedented in the ice core records that we
have.
�Acting now will minimise risk in the most cost-effective manner.�
Professor Stephan Lewandowsky from the School of Psychology says this
information is not dogmatic and the data is freely accessible on the
Internet.
He also says the number of scientific papers which have been
misrepresented in the media is disturbing.
He refers particularly to an article in The Australian, �Climate
claims fail science test�, stating scientists achieved a breakthrough
by revealing while the Earth was cooling, CO2 went up.
The article refers to research from a paper published in Nature,
�Atmospheric carbon dioxide through the Eocene�Oligocene climate
transition�, by Paul Pearson, Gavin Foster and Bridget Wade.
�In the paper, researchers said CO2 went down as [the Earth] was
cooling and is in agreement with carbon cycle modelling,� Prof
Lewandowsky says.
�How do you reconcile that with what The Australian is saying?
�So I sent [the authors of the paper] an email about it.
�They replied, �we also have difficulty reconciling our results this
article� and they submitted a letter to the Editor in which they say
�the article has misrepresented our recent research�.
�They concluded by adding their strong voices to the need to do
something about CO2.�
In response to the recent �Email-gate� scandal, Prof Lewandowsky says
�a conspiracy doesn�t make temperatures rise or ice caps melt�.
To finish, Professor Carmen Lawrence from UWA�s School of Psychology
presented a petition to rally support for the work of climate
scientists.
�It emphasises the importance of back the science and repudiating
deniers,� she says.
She says the statement aims to �prevent attacks on science�[which]
undermine and pervert healthy discussions�.
Post-event discussions and questions arose from both sides of the
debate.

Man made climate change/global warming is a proven lie, which makes you a
spamming liar.
