Since you're so fond of Graphs, I came across an interesting set of 'human influence' type today.
Reading this just a few minutes ago reinforces my long-standing contention that the working data has been over-stretched, much like a paperclip slowly worked to the breaking point by a bored office worker might discover when it all fell apart one day.
"Around Adelaide in South Australia and Melbourne in Victoria, the land surface temperatures were up to 12 degrees Celsius (22 degrees Fahrenheit) above average in mid-November. For Adelaide, the event was the first springtime heatwave since records began in 1887, according to the Australian Bureau of Meteorology. The city had temperatures above 35 degrees Celsius (95 Fahrenheit) for 8 consecutive days. (Five days at those temperatures constitutes a heatwave). Later in the month, some areas experienced heavy rain, which broke the heatwave in some areas, but not all."
And I know that weather's not climate.
It hasn't gotten better since 2003.
One bad weather station? OK. Does that explain this?
