Skilful Monthly Rainfall Forecasts

THE accurate weather forecast of James Stagg back in June 1944 is considered crucial to the successful D-day invasion that changed the course of WWII. Should we find ourselves at war again, is there an institution or individual capable of providing an accurate short or long-term weather forecast? Dr John Abbot and I are working towards […]

Bureau Still Limiting Cooling to Minus 10 Degrees

TWO weeks ago, in response to my queries the Australian Bureau of Meteorology acknowledged that it had put in place limits on the lowest temperature that an individual weather station could record.  So, when the automatic weather station which now operates in the town of Goulburn (not far from Canberra), recorded a measurement of minus […]

In Search of a New Way

FIFTY years ago, on 7 July 1967, Time magazine ran a cover story entitled, ‘The Hippies: Philosophy of a Subculture’.   Modern environmentalism is in some ways a product of this Flower Power movement, but a still-born version. It has become replete with particular moral codes – right ways of doing things – ostensibly underpinned by a […]

Bureau Now Sets Strict Limits on Cooling

OVER recent years I have documented the blatant remodelling of temperature measurements through the process of homogenisation. I have explained that it is the homogenised datasets that are used to report climate change by the Australian Bureau of Meteorology and the CSIRO.   I had assumed, however, that the raw data, kept in the CDO dataset, […]

Climate Change: The Facts 2017

Today’s Weekend Australian includes an article that begins: “Iconic, ailing Australian satirist Clive James has penned a savage essay on climate change alarmism, controversially cooking everyone from Barack Obama to Kevin Rudd to Tim Flannery to Al Gore to Donald Trump in the boiled and rising ocean of his wit…” The essay in The Inquirer section […]

Australia’s Hottest Day on Record Ever – Deleted

The last few days have been very hot across eastern Australia. The mainstream media have been reporting ‘unprecedented’ conditions. This fits a popular narrative, but its inconsistent with the original historical record. It was very hot in Australia in the late 1800s and the early years of the 1900s, particularly in outback Australia – at […]

This chart compares the homogenised-temperature trend with a trend based on simple statistical averaging - both series are purported to represent climate variability and change for the Northern Colorado Front Range, 1900 to 2015.

Homogenisation Used to Embed Artificial Warming Trend in Colorado Temperature Record

After looking at hundreds of temperature series from different locations across Australia, I’ve come to understand that only cities show the type of warming reported by the IPCC, and other such government-funded institutions. Much of this warming is due to what is known as the Urban Heat Island (UHI) effect: bitumen, tall-buildings, air-conditioners, and fewer […]
