The Garnaut Reviews’ errors and material omissions

Conclusion

It seems fair to conclude that the Garnaut Updates are selling Australia short, by proposing a major new tax on “carbon” based on very serious material omissions of information relevant to all the country’s stakeholders, not just its politicians and their far from objective advisers.

Note: the evident wide variability is much more closely correlated with ENSO phases (El Niños in 1998 and 2009 and La Niña in 1984 and 2010), as shown by the better fit (R²) for the polynomial trend line (top left) than for the linear (top right), than with the linear trend in atmospheric CO₂.
