Australian Met Office Accused Of Manipulating Temperature Records http://wattsupwiththat.com/2014/08/...manipulating-temperature-records/#more-114854 The [Australian] Bureau of Meteorology has been accused of manipulating historic temperature records to fit a predetermined view of global warming. Researcher Jennifer Marohasy claims the adjusted records resemble “propaganda” rather than science. Dr Marohasy has analysed the raw data from dozens of locations across Australia and matched it against the new data used by BOM showing that temperatures were progressively warming. In many cases, Dr Marohasy said, temperature trends had changed from slight cooling to dramatic warming over 100 years. –Graham Lloyd, The Australian, 23 August 2014 ... One of the most extreme examples is a thermometer station in Amberley, Queensland where a cooling trend in minima of 1C per century has been homogenized and become a warming trend of 2.5C per century. This is a station at an airforce base that has no recorded move since 1941, nor had a change in instrumentation. It is a well-maintained site near a perimeter fence, yet the homogenisation process produces a remarkable transformation of the original records, and rather begs the question of how accurately we know Australian trends at all when the thermometers are seemingly so bad at recording the real temperature of an area. Ken Stewart was the first to notice this anomaly andmany others when he compared the raw data to the new, adjusted ACORN data set. Jennifer Marohasy picked it up, and investigated it and 30 or so other stations. In Rutherglen in Victoria, a cooling trend of -0.35C became a warming trend of +1.73C. Sheraised her concerns (repeatedly) with Minister Greg Hunt. Now the Australian Bureau of Meteorology has been forced to try to explain the large adjustments. Australians may finally gain a better understanding of what “record” temperatures mean, and the certainty ascribed to national trends.

still waiting for the science that shows man made co2 is causing warming. but when you break down your graph you get this... and you see co2 trails change in ocean temps. "The maximum positive correlation between CO2 and temperature is found for CO2 lagging 11â12 months in relation to global sea surface temperature, 9.5-10 months to global surface air temperature, and about 9 months to global lower troposphere temperature. The correlation between changes in ocean temperatures and atmospheric CO2 is high, but do not explain all observed changes." See: http://dx.doi.org/10.1016/j.gloplacha.2012.08.008
You have no science showing temps lead CO2. Still waiting for it. Haven't seen it yet. On the other hand we all know CO2 is a greenhouse gas which by very definition leads temps higher. Get back to us when you have science showing otherwise. Lysenkoist.
here is a graph of the data showing co2 trails warming and cooling. the data come from NOAA and other nutter approved data sets. This is one of multiple studies on the subject you have been presented many times. For your level... do you see how well the green line follows the blue line. "The maximum positive correlation between CO2 and temperature is found for CO2 lagging 11â12 months in relation to global sea surface temperature, 9.5-10 months to global surface air temperature, and about 9 months to global lower troposphere temperature.

http://www.bbc.com/news/uk-scotland-highlands-islands-28885119 British Botanists conducting a Summer survey of Scotland’s tallest mountain, Ben Nevis, have been stunned to find evidence of recently formed multi-year ice fields, areas of compacted snow, some of which weigh hundreds of tons. According to the BBC; “Hazards common in arctic and alpine areas but described as “extremely unusual” in the UK during the summer have been found on Ben Nevis. A team of climbers and scientists investigating the mountain’s North Face said snowfields remained in many gullies and upper scree slopes. On these fields, they have come across compacted, dense, ice hard snow call neve. Neve is the first stage in the formation of glaciers, the team said.” The team has also encountered sheets of snow weighing hundreds of tonnes and tunnels and fissures known as bergschrunds. Source: http://www.bbc.com/news/uk-scotland-highlands-islands-28885119 This is how ice ages start – a buildup of snow which does not melt in the Summer, which leads to a positive feedback loop, as the growing ice sheet reflects more and more sunlight back into space.
http://www.sciences360.com/index.php/prepare-for-new-ice-age-now-says-top-paleoclimatologist-5899/ Geologic records show that Ice Ages are the norm, punctuated by brief periods of warming. Now one of the most highly respected paleoclimatologists has weighed in and is warning everyone to prepare for a new Ice Age. A new Ice Age? Then what's all the brouhaha about man-made global warming over the past 20 years? George Kukla, 77, retired professor of paleoclimatology at Columbia University and researcher at the Lamont-Doherty Earth Observatory responds, "The only thing to worry about global warming is the damage that can be done by worrying. Why are some scientists worried? Perhaps because they feel that to stop worrying may mean to stop being paid." The "Earth has experienced an ongoing cycle of ice ages dating back millions of years. Cold, glacial periods affecting the polar to mid-latitudes persist for about 100,000 years, punctuated by briefer, warmer periods called interglacials," Kukla says. Co-author of an important section of the book "Natural Climate Variability on Decade to Century Time Scales," Kukla asserts all Ice Ages start with a period of global warming. They are the harbingers of new Ice Ages. Actually, he explains, warming is good. Ice Ages are deadly and may even kill millions. Can Mankind stop it? No. Just as humanity cannot affect the long term climate of the planet, neither can it stop an Ice Age from happening. The climate is primarily driven by the sun. "I feel we're on pretty solid ground in interpreting orbit around the sun as the primary driving force behind Ice Age glaciation," he says. "The relationship is just too clear and consistent to allow reasonable doubt. It's either that, or climate drives orbit, and that just doesn't make sense."
