IPCC data vs BOM scam (Malcolm Roberts)

During the recent Senate Estimates Session with the Bureau of Meteorology (BOM), I tabled a graph from the United Nations Intergovernmental Panel on Climate Change (IPCC) report to challenge some of the exaggerated claims we've been hearing about extreme weather events such as cyclones, floods, and fires.

For years the BOM has always referred me to the IPCC’s work as the authoritative source on climate science. I specifically pointed to the IPCC’s Assessment Report 6, chapter 12, where they provide an analysis of a wide range of weather events. What struck me—and I think it should strike everyone—is that for nearly every major type of extreme weather event, the IPCC finds that there has been no detectable change in frequency or severity over time. This includes river floods, fire weather, tropical cyclones, and coastal floods. The data doesn’t support the claims that these events are becoming more frequent or intense because of "climate change".

This is important because politicians and the media have often linked these events to human-induced climate change. They claim that floods, fires, and cyclones are somehow the direct result of our carbon dioxide production.

Yet if the IPCC itself, the body these same politicians refer to, says there’s no significant change in these events, why aren’t we calling out this misinformation? Why isn't BOM calling out this misinformation?

For example, tropical cyclones - the IPCC indicates no change in their frequency or severity, not just for today, but looking ahead through to 2100—even under the worst-case climate scenario. And yet, we continue to hear false claims that “human-induced climate change" is worsening cyclone events. This isn’t true. These events have been part of the natural weather cycle for millennia.

The BOM Director, Dr Johnson's response acknowledged that the science on cyclones is evolving and confirmed that while there may be fewer cyclones in the future, the ones that do occur may be more intense. Yet again, these claims are based on unsubstantiated projections—not hard data. They're misinformation!

What’s more, looking at the IPCC's tables, which break down the evidence of (naturally) varying weather patterns, for nearly every phenomenon—whether it’s precipitation, floods, fire weather, or tropical cyclones—the data simply doesn’t support the idea of dramatic increases due to “human-induced” climate change. So, why are we still seeing politicians and the media push these claims?

This is not saying to ignore the importance of understanding climate variability, it’s about dealing with the facts - the measured data. The science must guide us, not the political agenda. And if the observed, measured scientific data says these extreme weather events aren’t changing as some claim, we need to stand firm against the misinformation. Let’s be clear: the data doesn’t support the alarmist rhetoric. We should be calling out the misinformation and ensuring that decisions, policies, regulations and public opinion are based on what the science actually tells us—not on what some want us to believe. I will continue to hold taxpayer funded agencies and politicians accountable. The truth matters, because, as always, it's we the people who pay.



The text points out that there are no measurable increased changes in weather events according the IPCC's data. Things they talk about are all projections. The stiffs in the suits know that if they report there is no climate emergency they'll lose funding or be fired. It's happened to a number of academics.

The things that are happening include the fact that sea levels are VERY slowly rising, but they have been since the end of the last Ice Age, where there is NO acceleration in the rate - something you would expect if humans were impacting the climate in the way they say.

As for the present temperatures over the last 100 years. The raw data shows little overall change, but when you factor in the manipulation of the data, the cooling of past temp readings in their summary charts, and using dodgy heat island readings, plus other factors, then you get an artificial temperature rise. If you look at the poles the ice coverage is not so different to the recent past. Antarctica recently came off record measured highs. The Arctic Ice Cap is not melting away. The key is to look at the raw data. Look at what the actual thermometer readings are in rural areas where it's obvious there is no overall change in recent times.

What's happened with the Climate Change issue (formerly Global Warming) is that it has become an ideologically driven, and financially driven, scam. It's putting money in the pockets of those participating in the lies - namely the NET ZERO/Carbon Tax finance capitalists, and other technocrats -those who want to tax and control everyone - plus academics who get money if their projects specifically acknowledge Climate Change.

Aside from scaring the general population into thinking it's the end of the world this scam is set to impoverish everyone and it needs to be exposed and stopped.
