Randall Carlson explains the hockey stick trick used to incite fear about global warming
Over many decades, several thousand papers were published establishing the Medieval Warm Period from about 900 AD to 1300 AD and the Little Ice Age from about 1300 AD to 1915 AD as global climate changes.
It came as quite a surprise when, in 1998, Mann et al. concluded that neither the Medieval Warming Period nor the Little Ice Age happened. The fudged temperature graph became known as the “hockey stick graph,” but it should be referred to as the “hockey stick trick.”
The graph was prominently featured in the 2001 Intergovernmental Panel on Climate Change’s Third Assessment Report and is used to this day to incite fear of man-made climate change
Randall Carlson is an architect and architectural designer who has appeared on podcasts where he discusses climate change and geological events. He argues that the Earth naturally goes through climate cycles, that current mass extinctions may not be unprecedented and that human influence on climate change is overstated for political reasons.
“The impact that we are having on the environment … is quite minimal … they’re using the impact of humans on the climate as, now, a political issue more than it is a scientific issue,” he said on the Koncrete podcast in 2021.

Carbon dioxide (CO2) is necessary for photosynthesis. Below 180 parts per million (“ppm”), there is too little carbon dioxide in the atmosphere for plants to survive. The first plants that will die off are “the stuff we eat,” Carlson said. Currently, atmospheric CO2 is 406 ppm. “If we look at the last 10 or 12,000 years, our baseline is now the lowest carbon dioxide has been in 600 million years,” Carlson said.
He then explained that, to exaggerate global warming, scientists removed data to create the “hockey stick” temperature graph.
In the first UN Intergovernmental Panel on Climate Change (“IPCC”) report published in 1992, it was admitted that temperature change was far higher in the Medieval Warming Period:
A recent study of documentary evidence in China (Wang and Wang, 1991; Wang et al, 1991) … [finds] good evidence in this region for a “Medieval Climatic Optimum” (S7, p 202) around 870-1110, another warm period around 1360 1570, and a “Littie Ice Age” (S7, p202) period around 1570-1750.

The Medieval Warm Period, also known as the Medieval Climate Anomaly or Medieval Climate Optimum, refers to a phase of warmer climate conditions that occurred roughly between 950 and 1300 AD, primarily in the North Atlantic region and much of northern and western Europe. It was characterised by warmer and drier conditions globally, with temperatures reaching levels of about 1-2oC warmer than they are now.
Because the Medieval Warming Period didn’t fit their narrative, they erased the Medieval Warming Period, Carlson said. “By the time the 1996 [IPCC] report came out, the whole graph of climate change temperature change from a thousand years ago to now was basically flattened … They got rid of the Medieval Warming Period and the Little Ice Age and … they flattened [the graph] out.”
“Then they added instrumental record on the end that looks like it’s going way up because it is not accounting for the urban heat island effect,” he added. “It was a completely contrived graph called the ‘hockey stick’. This is the [graph] that has been utilised since the mid-1990s to incite this fear [about climate change].”
