This book is a compilation of papers and essays on the climate change "debate". The main themes raise sufficient doubt to condemn the whole edifice of human induced climate change due to CO2 emissions.
Considering one theme - adjustment of temperature records. To my mind adjustment of the individual temperature records by considering adjacent temperature measurement cannot be justified at all. Some adjacent site are hundreds of kilometres apart. One wonders if the scientists making these adjustments have ever been outside and observed the microclimate changes in temperature that occur from metre to metre in some cases. Granted there are problems with obtaining continuous temperature records in one location that have been made with the same instruments in the same physical environment but where inconsistent records exist they usually cannot be reliably corrected except under well defined circumstances. (As an aside this reviewer has been involved for much of his professional life with correlating standard tests between laboratories and this is often problematical even though it is a much less complex problem than trying to correlate field measurements.)
In summary this book requires careful reading by the climate scientists and policy makers.
