"The Bureau of Meteorology (BoM) initially claimed the adjustments were part of its quality control procedures. But bureau chief executive Andrew Johnson later told Environment Minister Josh Frydenberg that investigations had found a number of cold-weather stations were not “fit for purpose” and would be replaced."
Aussie temperature tampering scandal: “Smart cards” filter out coldest temperatures. Full audit needed ASAP! - 'The story changes: first it was quality control, then equipment failure, now a smart card?'
NASA's Gavin Schmidt counter claims: 'This whole article is based on a confusion that we know the absolute temperature of the Earth better than the changes. We do not...As estimates improve (within the real uncertainty), you can get weird jumps in the absolute temps reported that have nothing to do w/trends...If I am measuring how tall my child is growing, do I need to factor in my elevation above sea level? No. I just need a stable doorpost.'
Monckton: 'Hey presto! No more Inconvenient Pause! All gone! Vanished into thick air! Just like that! Amazing! Zowee! Look! A quarter of a degree of global warming where there was none before! It’s worse than we thought!'
'RSS now shows a warming almost 50% greater than the UAH warming.'
'On most of the global-temperature datasets, much of the warming of recent decades was not evident in the raw data and has been created by ex-post-facto manipulation of the data – whether for good reasons or bad'
'No Inconvenient Pause will ever again be allowed to show in most datasets, even if there is one. Some parameter or another will be Karlamelized after the event, and numbly acquiescent pal-reviewers will check it not for scientific merit but simply for conformity to the Party Line, whereupon they will wave the paper through.'
A study published June 27 by two scientists and a veteran statistician. The peer-reviewed study tried to validate current surface temperature datasets managed by NASA, NOAA and the UK’s Met Office, all of which make adjustments to raw thermometer readings. Skeptics of man-made global warming have criticized the adjustments. Climate scientists often apply adjustments to surface temperature thermometers to account for “biases” in the data. The new study doesn’t question the adjustments themselves but notes nearly all of them increase the warming trend. Basically, “cyclical pattern in the earlier reported data has very nearly been ‘adjusted’ out” of temperature readings taken from weather stations, buoys, ships and other sources. In fact, almost all the surface temperature warming adjustments cool past temperatures and warm more current records, increasing the warming trend, according to the study’s authors.
The China Meteorological Administration (CMA) has recently developed a new global monthly land-surface air temperature data set called CMA GLSAT. Using it researchers from the administration reanalysed the change in global annual mean land-surface air temperature during three time periods (1901–2014, 1979–2014 and 1998–2014) to see if there was any evidence of a hiatus or pause in recent surface global warming.The researchers find very clear evidence for the recent warming hiatus...Their results show linear trends of 0.104 °C per decade, 0.247 °C per decade and 0.098 °C per decade for the three periods, respectively. The trends were statistically significant except for the period 1998–2014, the period that is also known as the ‘‘warming hiatus”.
