ACORN adjustments robbed Marble Bar of its legendary world record. Death Valley now longest hottest place

For generations it was a Guinness Book of Records type thing. Now it’s gone. In 1924 Marble Bar set a world record of the most consecutive days of 100 °F (37.8 °C) or above, during an incredible period of 160 days starting in 1923. It was legend — but thanks to the genius homogenized adjustments, we now find out all along it was wrong. It’s another ACORN triumph, rewriting history, extinguishing the hot days of days long gone. The experts at the Australian Bureau of Meteorology (BoM) have reanalyzed the temperatures from 4000 km away and nine decades in the future and apparently it wasn’t that hot.

Chris Gillham wonders how the bureau figured out the Marble Bar max was one whole degree too warm on 18 Nov 1923, but it was 0.6°C too warm on 19 Nov 1923, 0.3°C too warm on 20 Nov 1923, 0.2°C too warm on 21 Nov 1923, and 0.8°C too warm on 22 Nov 1923? He points out the sky was totally clear every day, the screen didn’t get shuffled around every day, etc, so where’s the logic? The world record was extinguished because on 8 March 1924 the ACORN adjustments magically cooled the temperature from […]
