Excerpts from the three part series below.
A significant amount of evidence indicates that the global temperature did increase during the 20th century. For example, direct thermometer measurements indicate that the temperature increased by perhaps 0.8Â°C.
In summary, there is no direct evidence showing that CO2 caused the 20th century warming, or as a matter of fact, any warming. The question to ask is therefore can we point to some other culprit? If humans are not the only ones responsible Read more [...] 6 com
Ken Stewart has released his much awaited review of the Australian High Quality Sites. His conclusion:
The High Quality data does NOT give an accurate record of Australian temperatures over the last 100 years.
BOM has produced a climate record that can only be described as a guess.
The best we can say about Australian temperature trends over the last 100 years is â€œTemperatures have gone down and up where we have good enough records, but we donâ€™t know enough.â€

My wife does not provide the best example of demonization, but it is current, motivational and recent and on my mind. Please excuse me if I become too personal. The important part is not the personal part. It is Read more [...] 30 com
The Age reports that Climategate was a game changer. Judith Curry said Dr Jones had shown himself to be ''genuinely repentant, and has been completely open and honest about what has been done and why â€¦ speaking with humility about the uncertainty in the data sets''.
So far its a case of the academic defense: "Oops, I lied." Sir Muir Russell, the chairman of the Judicial Appointments Board for Scotland, notes that senior climate scientists say their world has been dramatically changed by Read more [...] 8 com
