BoM Temperature Data Audit: Fact-Checking The Australian's Claims 2026

The Australian newspaper has launched a major reporting campaign claiming widespread errors in BoM temperature data, but the evidence behind these big claims is now under scrutiny. The Bureau of Meteorology has responded firmly, stating that the allegations are based on "several misunderstandings" and that accusations of human intervention in the data are "false and unsubstantiated." This dispute matters because the Bureau's temperature records show Australia has warmed by more than 1.5C since 1910, and discrediting that data could undermine the case for cutting greenhouse gas emissions.

What The Australian Claims About BoM Temperature Data

The Australian's reporting campaign is based on what it calls a "forensic audit" of the Bureau's temperature records. The newspaper claims to have found "widespread errors" that raise "questions about the integrity of records used for climate analysis." These are serious allegations that would require remarkable evidence to support.

Former prime minister and climate science denier Tony Abbott has called for an independent review, while News24 (formerly Sky News Australia) and 2GB also promoted the story. The claims have energized climate science denial blogs, but the Bureau's response suggests the audit may have misunderstood how temperature data is processed.

The Bureau's Response to the Allegations

On Thursday night, the Bureau of Meteorology released a statement rejecting the claims. It said the allegations were based on "several misunderstandings" and that accusations of human intervention in the data were "false and unsubstantiated." The Bureau has made its raw temperature data publicly available for years, allowing independent scrutiny.

The Bureau's temperature records have been a constant target for climate science sceptics for more than 15 years. This latest campaign is part of a long-running effort to cast doubt on the data, but the Bureau maintains that its methods are transparent and scientifically sound.

Why Temperature Data Adjustments Are Necessary

When it comes to temperature records, the Bureau makes raw data from its weather stations available to the public. However, raw data alone can be misleading because weather stations change over time—they may be moved, surrounded by new buildings, or have equipment upgraded. Scientists apply adjustments to account for these factors and create a consistent long-term record.

These adjustments are not evidence of manipulation; they are a standard part of climate science. The Bureau's adjustments have been documented and peer-reviewed, and they actually have a minimal effect on the overall warming trend. The claim that adjustments are used to artificially inflate warming is a common misconception.

Earlier coverage in Strongest El Niño on Record: Climate Change Impact on Australia shows how the argument developed.

The Stakes: Undermining Climate Action

If the Australian's claims were true, they would undermine the entire climate change story and the rationale for cutting Australia's greenhouse gas emissions. That is why the newspaper's campaign has attracted so much attention from climate science deniers.

The same theme surfaces in Customers Don’t Prefer AI Chatbots to Humans – Fact, which takes a different angle.

But the evidence for the Bureau's temperature record is strong and has been independently verified. The warming trend is consistent with global observations and with the physical understanding of greenhouse gas impacts. Discrediting the data would require far more than a newspaper audit; it would require a fundamental rewrite of climate science.
