The Blaze is Right, Justice Kagan Was Careless Endorsing Bad Climate Science

A recent article at The Blaze, “Elena Kagan gave bogus science a blind endorsement,” says Supreme Court Justice Elena Kagan’s glowing forward endorsing the Federal Judicial Center’s (FJC) “Reference Manual on Scientific Evidence (RMSE)” was inappropriate and careless, since she has subsequently said she hadn’t read the document. The RMSE is biased, giving undo weight to so-called “scientific consensus” over empirical data.

A recent article at The Blaze, “Elena Kagan gave bogus science a blind endorsement,” says Supreme Court Justice Elena Kagan’s glowing forward endorsing the Federal Judicial Center’s (FJC) “Reference Manual on Scientific Evidence (RMSE)” was inappropriate and careless, since she has subsequently said she hadn’t read the document. The RMSE is biased, giving undo weight to so-called “scientific consensus” over empirical data. At least one of the chapters was written in large part by plaintiffs’ advocates and supporters in ongoing climate litigation, including a case soon to be argued before the Supreme Court. The Blaze’s recommended fixes, rewriting the document to restore neutrality and restoring an emphasis on data and evidence, as well as its suggestion that judges be cautious in relying on such manuals, are on the mark. In addition, Kagan shouldrecuse herself from the pending climate case, since her claimed uninformed endorsement of one side of the argument in advance gives the appearance of impropriety.

The post, written by the CO2 Coalition’s executive director Angela Wheeler, describes how at a recent Senate hearing Supreme Court Justice Elena Kagan admitted that she never actually read the FJC manual that she wrote a forward for. Her forward, troublingly, describes the manual as objective and neutral, and suggests that it would be a reliable resource “for judges handling cases involving complex scientific evidence,” including climate related litigation.

Wheeler examined previous editions of the manual, finding them scientifically rigorous. Those earlier editions stressed the need to rely on hard science, data, and the scientific method. By contrast, the recent edition that Kagan signed off on had multiple chapters that placed emphasis on “social considerations and consensus among experts while giving less attention to the rigorous testing that separates science from assertion.”

This is an issue previously raised at Climate Realism and discussed here and here. Climate Change Weekly raised concerns about problems with the RMSE here, here, and here. The fourth edition of the FJC manual originally had an entire chapter devoted to climate change, which alarmingly was penned by activists and climate-plaintiff lawyers who were involved in ongoing climate lawsuits filed against energy companies. Those authors and contributors have clear interests in the science being interpreted their way to produce the outcomes they desire. Objective discussion of climate data had no place in the manual.

Attribution studies claiming that individual weather events could be attributed at least in part to specific emissions are unscientific, based on notably flawed and inadequate computer models that have consistently produced inaccurate forecasts. Climate Realism has discussed the myriad problems with attribution “science” here.

Models, of course, aren’t data, and neither is scientific consensus. Wheeler explains that consensus and collaboration matter and can lead to useful evidence, “[b]ut ‘widespread agreement’ cannot substitute for disciplined scrutiny, especially in court.”

In the case of the so-called “climate consensus,” there is a lot less consensus than activists would have us believe. The actual areas of scientific agreement are much more nuanced. Few scientists believe in anything like a “climate catastrophe,” or that individual storms can be blamed on any particular oil and gas company.

The most egregious chapter of the FJC manual was removed after public outcry, but the consensus narrative and subtle pushes towards activist-driven science remain.

Wheeler suggests that it is not too late for FJC to restore trust. To do so, the manual needs to emphasize data and “empirical verification, seek broader input from experts without policy entanglements, and reaffirm the manual’s limited role as a procedural guide rather than an arbiter of scientific truth.” She goes on to say that manuals like this shouldn’t be used as shortcuts or substitutes for research, but as mere “starting points.”

These steps are likely to help FJC look more trustworthy. However, it is still a problem that Justice Kagan was so negligent in praising a manual she now claims to have not read, especially when it addressed how to interpret science matters pending to a case before the Supreme Court.

With a major climate litigation case coming up in October, it is more important than ever that judges are not tricked into accepting overstated and politicized climate attribution studies, among other theoretical model-based presentations, as evidence. The standard for science, whether inside or outside the courtroom, should never be mere speculation, but solid proof.

Frequency of Dust Storms: Increases Due to Climate Change (WHO, 2025) vs Decreases Due to Complex Factors in the Sahara-Sahel Region (Yeo et al., 2026)!

Dust storms (also called sandstorms) are meteorological events where strong winds lift loose sand, dust, and dirt from dry surfaces into the air, creating clouds or walls of particles that reduce visibility and can travel long distances.

Haboobs are intense dust storms triggered by thunderstorm downdrafts. They appear as dramatic advancing walls of dust, sometimes thousands of feet high and miles long.

The most infamous is the Dust Bowl of the 1930s in the U.S. Great Plains.

The prevailing climate narrative is that the frequency of dust storms (Fig. 1) tends to increase with global warming (Fig. 2). But the empirical datasets from the Sahara-Sahel region (Fig. 3) reveal that the opposite trend is true for the period 1984-2023 (Fig. 4).

Dust storms

A dust storm, also called a sand storm, is a meteorological phenomenon common in arid and semi-arid regions. Dust storms arise when a gust front or other strong wind blows loose sand and dirt from a dry surface. Fine particles are transported by both saltation and suspension.

Dust storms commonly begin when:

· A dry cold front sweeps through.

· A thunderstorm collapses, creating a powerful downdraft.

· Strong pressure gradients generate high winds.

The most dramatic type—a haboob—forms when a thunderstorm’s downdraft hits desert soil and spreads outward like a giant broom, lifting a massive wall of dust. These dust storms can reduce visibility, disrupt transportation, and pose serious health risks. The arid regions (Fig. 1) of North Africa, the Middle East, Central Asia and China are the main terrestrial sources of airborne dust (Wikipedia https://en.wikipedia.org/wiki/Dust_storm). A major desert dust storm can rise 1,500–2,000 m high and advance at 60–80 km/h, with some gust fronts exceeding 100 km/h. Visibility often drops to zero. They can stretch hundreds of kilometers, with rare events spanning up to 1,000 km.

Climate-Change Narrative

The World Health Organization (WHO, 2025) states that “Climate change contributes to desertification, which in turn may increase the frequency and spread of sand and dust storms. Recently, the WHO Eastern Mediterranean Region and other areas have observed a surge in frequency, duration and intensity of sand and dust storms.” However, WHO (2025) did not explain the details of how Climate Change can increase the frequency of dust storms.

Empirical Data from North Africa

In a comprehensive regional study of dust storms in the Sahara-Sahel region of North Africa, Yeo et al. (2026) have documented that North African dust storms have undergone marked variability, reflecting complex interactions between regional climate processes and environmental change. These authors, using four decades (1984–2023) of visibility‐based observational records, have examined regional and seasonal trends in dust storm frequency across the Sahel and the Sahara, capturing their distinct dust dynamics.

Results reveal a significant decline in dust activity in both regions (Fig. 4), most pronounced during pre‐monsoon (MAM) and monsoon (JJA) seasons in the Sahel, and during post‐monsoon (SON) and dry season (DJF) in the Sahara. Integrating surface observations with local meteorology (precipitation, surface wind speed, vegetation) and climate indices (AMO, NAO, MEI), Yeo et al. (2026) find the Atlantic Multidecadal Oscillation (AMO) as the primary driver, with region‐specific effects: in the Sahel, AMO‐driven warming and rainfall increase vegetation, suppressing dust; in the Sahara, AMO intensifies the Saharan Heat Low (SHL) and elevates temperatures, modulating dust through atmospheric stability and wind patterns. Local meteorology further differentiates responses, with precipitation and Leaf Area Index (LAI) dominating dust variability in the Sahel, while SHL strength and surface winds are most influential in the Sahara. By explicitly separating the Sahel and Sahara and integrating multiple drivers, this study provides a more spatially resolved understanding of dust–climate link and suggests continued declines in North African dust storm activity under future warming.

In light of the Climate Narrative, it is worth noting that “Desertification and dust productions are caused by low CO2 concentrations” (Palmer and Elias, 2016).

Implications

Clearly, available empirical datasets from North Africa do not validate the notion that Fossil Fuels and related CO2 emissions (as implied by the WHO narrative) are the cause of increasing frequency of dust storms. Dust storms are products of meteorological factors. In this context, humans are utterly impotent when it comes to controlling Forces of Nature (e.g., Dust storms, Cyclones, Tsunamis, Volcanoes, Meteorite Impacts, and Earthquakes). Humans can neither create nor stop Extreme Weather Events!
