BomWatch: Auditing the fake warming created by site changes near the Great Barrier Reef

All along the coast near the Great Barrier Reef, the BOM has claimed temperatures have warmed in the last 50 years, and they’ve calculated it to a tenth of a degree. To get that kind of accuracy the thermometers need to be carefully placed, and the BOM needs to know exactly where they were, but they don’t.

The BOM keeps long pages of site descriptions and exact dates of moves and equipment changes, but historic photos show the records are wrong. The BOM will solemnly swear a site was in the same place for decades but photographs and archives show the sites were often moved as developments sprang up around them. The BOM didn’t keep the records and didn’t bother to check. If the thermometer moved to a warmer location or it warmed because they replaced the standard 230-litre Stevenson screen with a 60-litre toy one, or no longer cleaned it of dust and grime that’s climate change at work (Ka-Ching). There’s probably a thermometer 500km away that can be used to “correct” the record. (Like say, Coen or Musgrave which are used to “adjust” Cairns and are 452 km and 746 km away!). Near enough’s rough enough! Homogenisation is fatally flawed and should be abandoned.
