“Shattered Consensus”: A Thought-Provoking Challenge to Climate Orthodoxy, By Brian Simpson

In the contentious arena of climate science, Patrick J. Michaels' Shattered Consensus: The True State of Global Warming stands out as a bold and provocative contribution. As a former president of the American Association of State Climatologists, Michaels brings a wealth of expertise to his critique of the prevailing climate change narrative. His book is a profound call for critical thinking, urging readers to scrutinise the evidence, methodologies, and motivations behind the global warming consensus. In an era where climate policy shapes economies and societies, Michaels' demand for a more nuanced, evidence-based approach is both timely and essential.

At the core of Michaels' argument is his critique of the Intergovernmental Panel on Climate Change (IPCC), the United Nations body often regarded as the definitive voice on climate science. Michaels contends that the IPCC's Summary for Policymakers overstates the certainty of human-driven global warming, particularly in attributing over half of the enhanced greenhouse effect to CO₂. He highlights inconsistencies in the IPCC's projections, such as drastic temperature increase predictions that sideline significant scientific uncertainties. By challenging the IPCC's authority, Michaels encourages readers to question whether the organisation's conclusions are as unassailable as they are often portrayed.

One of Michaels' most compelling arguments focuses on the infamous "hockey stick" graph, which claims that recent temperatures are the warmest in a millennium. Michaels meticulously dissects the graph's foundation, pointing to flaws in the methodology of the original MBH98 study. For example, he notes discrepancies in the data, such as the South America PC calculation listing 18 sites in the original paper, but only 11 in the archived data. These inconsistencies raise legitimate questions about the graph's reliability and suggest that the narrative of unprecedented warming may be overstated. Michaels' scrutiny of this cornerstone of climate alarmism exemplifies his commitment to rigorous scientific inquiry.

Michaels also challenges the IPCC's handling of the urban heat island effect, where urban areas experience higher temperatures due to human activities like construction and industrialisation. He argues that the IPCC underestimates this phenomenon, which could account for a significant portion of observed warming. Studies cited by Michaels suggest that land-use changes, including urbanisation, have a biasing effect on temperature records that is roughly three times larger than previously estimated. By highlighting this overlooked factor, Michaels provides a compelling case that not all warming can be attributed to greenhouse gas emissions, urging a more comprehensive analysis of temperature data.

Another strength of Shattered Consensus is its focus on natural climate variability. Michaels disputes the IPCC's claims about increased frequency and intensity of El Niño events, arguing that historical data does not support these assertions. He points to a strong correlation between solar irradiance and near-surface air temperature anomalies, suggesting that solar changes played a significant role in early 20th-century warming, comparable in magnitude to late 20th-century warming. This perspective challenges the dominant narrative that human activities are the sole drivers of climate change, advocating for a broader consideration of natural factors.

Michaels' critique extends to the reliance on climate models, which he argues produce inconsistent predictions and fail to adequately account for complex factors like natural variability and cloud dynamics. By overemphasising CO₂ as the primary driver of climate change, these models, according to Michaels, oversimplify a multifaceted system. His analysis underscores the limitations of current modelling approaches and calls for greater humility in acknowledging what we don't yet fully understand about the climate system. This critique is particularly relevant as policymakers increasingly rely on model projections to justify sweeping interventions.

One of the book's most grounded arguments is its challenge to the notion that global warming is driving an increase in severe weather events. Michaels cites studies showing no significant trend in the frequency or intensity of hurricanes, tornadoes, or other extreme weather phenomena over the past century. He accuses the media of sensationalising weather events, creating a public perception of heightened severity that lacks empirical support. This evidence-based rebuttal is a powerful reminder to separate fact from alarmist rhetoric, encouraging a more rational discussion about climate impacts.

Shattered Consensus is not merely a critique but a passionate plea for open-mindedness and intellectual rigour in climate science. Michaels does not deny the existence of global warming, but insists that its causes, extent, and consequences are far more complex than the prevailing narrative suggests. His book serves as a counterbalance to the often-one-sided discourse, urging readers to question assumptions and consider alternative perspectives before endorsing policies with far-reaching consequences. In a field where consensus can sometimes stifle debate, Michaels' voice is a vital reminder of the importance of scepticism and critical inquiry, when the very existence of Western industrialism is at stake.
