Australian Fires: Climate ‘Truth Bomb’?

Recipe for Australia’s climate ‘truth bomb’:  dubious manipulations of the historical temperature record, ignorance of the climate dynamics of the Southern Hemisphere, and ignorance of Australia’s ecological and social history.

A correspondent of The Guardian newspaper writes that her personal ‘climate truth bomb’ hit her while she was picking ash from her glass at a wine tasting event – the Sydney Harbour bridge being dimly seen through the murk of bushfires. The truth came to her, she wrote, in the eloquent rage of Greta Thunberg and also in heat, smoke and fire.

What To Make Of The Bureau Of Lying Statistics’ Contradicting Jobs Reports

By David Haggith – Re-Blogged From The Great Recession Blog

Employment has been the one stickler in my recession prediction for 2019, and finding a trustworthy measurement from the government’s statistics is like finding a virgin in a brothel. Depending on which official figures you look at, employment has refused to fall and new jobs are strong … or they stink.

We recently got two extremely conflicting reports from the same government agency that reveal, AGAIN, how dubious the official numbers from the government are. Because one report was stellar, the stock market blasted off like a rocket when it heard the news. Because the other report of the same item was abysmal, the stock market ignored it. The Fed, however, did not ignore it, and carries it in its official charts.

Cooling the Past

It is not disputed that Blair Trewin under the supervision of David Jones (both working at the Australian Bureau of Meteorology) remodel all the historical temperature data generating trends and statistics that look quite different from the actual measurements.

The remodelled series are then passed on to university and CSIRO climate scientists who base much of their climate research on these ‘second-hand’ statistics.

So, when Michael Mann and David Karoly tell you it’s getting hotter and hotter, this is their interpretation of Blair Trewin’s statistics, not their interpretation of the actual data.

Which Data to Believe

Re-Blogged From WUWT

Today, at the big 100 year anniversary shindig of the American Meteorological Society (AMS) there was a press release session that featured NOAA and NASA GISS talking about how their climate data says that the world in 2019 was the second warmest ever.

Here is their slideshow presentation, released today: https://www.ncdc.noaa.gov/sotc/briefings/20200115.pdf

In my opinion, the NOAA/NASA press release (and slideshow) is inconsistently presented. For example, they can’t even agree on a common base period for comparisons. Some graphs use 1951-1980 while others compare to 1981-2010 averages to create anomaly plots. NOAA and NASA owe it to the public to present climate data with a consistent climate period for comparison, otherwise it’s just sloppy science. NASA GISS has consistently resisted updating the 1951-1980 NASA GISS baseline period to the one NOAA and other datasets use, which is 1981-2010. GISS stubbornly refuses to change even though they have been repeatedly excoriated for keeping it.

Alternate Inflation Charts

Re-Blogged From Shadow Stats

The CPI chart on the home page reflects our estimate of inflation for today as if it were calculated the same way it was in 1990. The CPI on the Alternate Data Series tab here reflects the CPI as if it were calculated using the methodologies in place in 1980. In general terms, methodological shifts in government reporting have depressed reported inflation, moving the concept of the CPI away from being a measure of the cost of living needed to maintain a constant standard of living.

Further definition is provided in our  CPI Glossary. Further background on the SGS-Alternate CPI series is available in our Public Comment on Inflation Measurement.

Detection of UHI bias in China climate network using Tmin and Tmax surface temperature divergence

Nicola Scafetta a, Shenghui Ouyang b

Abstract Near-surface temperature records show that China warmed by about 0.8 °C from 1950 to 2010. However, there exists an ongoing debate about whether this warming might have been partially due to urbanization bias. In fact, homogenization approaches may be inefficient in densely populated provinces that have experienced a significant urban development since the 1940s. This paper aims to complement previous research on the topic by showing that an alternative approach based on the analysis of the divergence between the minimum (Tmin) and maximum (Tmax) near-surface temperature records since the 1940s could be useful to clarify the issue because urban heat island (UHI) effects stress the warming of nocturnal temperatures more than the diurnal ones.
