In conclusion, all three analysis approaches had similar results that point towards substantially less global warming within the last 140 years than previously thought.

“For many years, the general public has been assuming that the science on climate change is settled. This new study shows that this is not the case.”

Thus, it appears that NOAA’s homogenization procedure is spuriously warming station temperature trends (on average) when it should be cooling them. I don’t know how to conclude any different.

Australian’s are being misled by data-wranglers, climate-modelers and institutions they should be able to trust. Read on …   

Appoint a task force to come up with appropriate width of the error bars. There should be some kind of sophisticated statistical model to generate this, but I would think that error bars of +/- 0.5 deg C are eminently justifiable.

These long periods of time mean that it is practically impossible to maintain the same measuring conditions over the years. The most common problem is the growth of cities around urban weather stations. We know that cities...

It’s just not cricket. And in so many ways. Shame to let a perfectly good dataset go to waste… Australian data comes from some of the longest stations running in the Southern Hemisphere, it could be useful. Instead...

Temperature stations are known to be affected by numerous forms of inhomogeneity. Allowing for such inhomogeneities is an interesting and not very easy statistical problem. Climate scientists have developed some homemade...
