Most global warming is natural and even if there had been no Industrial Revolution current global temperatures would be almost exactly the same as they are now, a study has found.
The paper, by Australian scientists John Abbot and Jennifer Marohasy, published in GeoResJ uses the latest big data technique to analyse six 2,000 year-long proxy temperature series from different geographic regions. “Proxies” are the markers scientists use – tree rings, sediments, pollen, etc – to try assess global temperature trends in the days before the existence of thermometers. All the evidence suggests that the planet was about a degree warmer during the Medieval Warming Period than it is now; and that there is nothing unnatural or unprecedented about late 20th century and early 21st century “climate change”.
This contradicts the claims of alarmist scientists at the Intergovernmental Panel on Climate Change that “man made” global warming is a worrying and dangerous phenomenon.
Australia’s Bureau of Meteorology (BOM) has been caught red handed erasing record-breaking cold temperatures from its data records.
The BOM has now been shamed by media investigations into ordering a review of its procedures. But it has yet to provide an explanation as to why it made these “adjustments” in the first place.
These “adjustments” seem to go only one way. The BOM is perfectly happy to record and announce it whenever Australia’s temperatures hit record-breaking highs. But when the temperatures reach new lows it’s a different matter altogether.
For some strange reason that the BOM has been unable to explain, when temperatures go below a certain point it either deletes them as if they had never been – or it enters them into its records at higher temperature than the one actually recorded by its thermometers.
The Australian Bureau of Meteorology has been caught red-handed manipulating temperature data to show “global warming” where none actually exists.
At Amberley, Queensland, for example, the data at a weather station showing 1 degree Celsius cooling per century was “homogenized” (adjusted) by the Bureau so that it instead showed a 2.5 degrees warming per century.
At Rutherglen, Victoria, a cooling trend of -0.35 degrees C per century was magically transformed at the stroke of an Australian meteorologist’s pen into a warming trend of 1.73 degrees C per century.
Last year, the Australian Bureau of Meteorology made headlines in the liberal media by claiming that 2013 was Australia’s hottest year on record. This prompted Australia’s alarmist-in-chief Tim Flannery – an English literature graduate who later went on to earn his scientific credentials with a PhD in palaeontology, digging up ancient kangaroo bones – to observe that global warming in Australia was “like climate change on steroids.”
But we now know, thanks to research by Australian scientist Jennifer Marohasy, that the hysteria this story generated was based on fabrications and lies.
