According to Dr Willem Bouma, a science policy analyst with the Division of Atmospheric Research in Melbourne, critics like the University of Virginia's Professor Patrick Michaels, Dr Richard Lindzen of the Massachusetts Institute of Technology, and Dr Brian Tucker, former head of the CSIRO Division of Atmospheric Research, are out of date when they contend that the science behind the report is too weak to be taken seriously.
"There has been a remarkable shift over the last five or six years," Dr Bouma
claims this up-front honesty is frequently misunderstood and may "cloud the fact that the major conclusions as reported by the IPCC
are quite robust".
suggests candidly, have been "burdened too much" by their own awareness of the complexity of climate change.
Rather, scientists have "a duty to speak out", says Dr Bouma, who agrees with Dr Klaus Hasselmann, of the Max Planck Institute for Meteorology in Germany, that researchers are obligated to provide the most reliable information possible.
