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 […]

Understanding the Wild, Wet Weather across Southern Australia

The wild, wet weather across southern Australia this spring is a consequence of an unusually strong temperature gradient, especially evident in the following chart as warm water to the north of Australia (especially in the Timor and Arafura Seas), and the cold waters off the southwest of Australia. Former head of Australia’s National Climate Centre, […]

Speaking Truth to Power, and Correcting Brian Cox

There was once a clear distinction between science – that was about reason and evidence – and art that could venture into the make-believe including through the re-interpretation of facts. This line is increasingly blurred in climate science where data is now routinely remodeled to make it more consistent with global warming theory.

Green squares show annual mean minimum temperatures, red dots show these values after homogenization.  In dropping down the early mean minima the Bureau changes slight cooling at Rutherglen, into warming of 1.7 degrees Celsius per century.

Auditor-General Dismisses Need for Scrutiny of Bureau’s Homogenization Methodology

SURFACE air temperatures, as measured at weather stations across Australia, are routinely remodeled through a process of homogenization.  After the remodeling of approximately 100 individual temperature series, various area weightings are applied to these individual series, then the average annual temperature is calculated for each state and territory, the entire continent, and used to report […]

Accepting Regional Variability in Global Temperatures

IN the very first report from the United Nation’s Intergovernmental Panel on Climate Change (IPCC) the Medieval Warm Period was evident as a period, about as warm as the present, occurring from AD 950 to 1250. In subsequent IPCC reports there is no such warm period in this historical record. Instead there is a graph, […]

Satellite-based global temperatures, trending up

LEADING climate scientists were not acknowledging “the pause” in global warming, even though it was very apparent in the satellite-based temperatures of the lower troposphere. That was until last month. The February update to this satellite record has broken previous records for the northern hemisphere, and indicates that global temperatures are once again on the […]

Rainfall Forecasts Should be Benchmarked

ACCORDING to Bill Gates, “You can achieve incredible progress if you set a clear goal and find a measure that will drive progress towards that goal.” This may seem basic, but it’s not practiced enough, and certainly not when it comes to rainfall forecasting. The Bureau of Meteorology increasingly use their weather and climate forecasts […]
