Meteorologist debunks climate change narrative: Heatwaves in USA were more frequent from 1901-1960

The narrative that climate change is producing unprecedented, relentlessly intensifying, runaway heatwaves across the United States has been a cornerstone of environmental alarmism for years. From cable news segments to political speeches, the public is told that every passing summer brings record-shattering temperatures, a direct and ominous consequence of human activity. Yet, an examination of the underlying meteorological data, sourced directly from the National Oceanic and Atmospheric Administration’s own Global Historical Climatology Network daily (GHCNd), tells a remarkably different story.

The numbers do not show a steady, unrelenting march toward a fiery apocalypse; instead, they reveal that the most extreme heat events in the United States were more prevalent during the early 20th century, specifically the period from 1901 to 1960, and that the frequency of days reaching the punishing thresholds of 100°F and 105°F has actually declined since 1895. This dataset, which is an integrated database of daily climate summaries from land surface stations across the globe, provides a long-term perspective that directly challenges the contemporary narrative of crisis.

Key points:

• A review of GHCNd data shows that the average number of days per year reaching 95°F was significantly higher in the 1901-1960 period compared to 1961-2020.
• The number of days reaching 100°F and 105°F has not increased in recent decades and has declined since 1895 .
• The climate of the modern era, while warm, lacks the extreme, blistering heat that characterized the 1930s and other periods in the first half of the 20th century.

What the Official Numbers Really Show

The foundation of the alarmist argument rests on a selective reading of climate data, often focusing on localized events or shorter time frames to create a sense of immediate, linear catastrophe. However, when one takes a broader, more historically honest view using the extensive GHCNd database, which contains records from more than 100,000 stations in 180 countries, a different pattern emerges. The data clearly shows that the period from 1901 to 1960 experienced more frequent and severe heatwaves across the contiguous United States than the period from 1961 to 2020. This is not a matter of opinion or interpretation; it is a matter of simple arithmetic.

Meteorologist Chris Martz, who has analyzed this publicly available data, has pointed out that the average number of days per year reaching 95°F was approximately 18% lower during the latter 60-year period. The chart is published on his X account.

This is a significant statistical anomaly for those who claim that the planet is experiencing unprecedented warming that manifests as relentless extreme heat. If the theory of heatwave intensification due to man-made emissions were absolute, one would expect to see a smooth, upward trajectory in these specific metrics. Instead, the data suggests a plateau and even a decline in the most extreme temperature thresholds. The “Dust Bowl” era of the 1930s, for instance, stands out as a period of exceptional and unrelenting heat, a historical reality that is often awkwardly sidestepped by those who insist that the current climate is uniquely severe.

Connecting the Dots to a Broader History

The fact that extreme heat events were more common in the early 20th century does not fit neatly into the prescribed narrative of a climate system pushed beyond historic norms by the modern industrial age. It forces one to question the methods and motivations behind the messaging that dominates the public discourse. The GHCNd database is a comprehensive tool, the result of integrating daily climate records from numerous sources and subjecting them to a common suite of quality assurance reviews. It is the very same data that NOAA uses for its own analyses, making the decline in 100°F and 105°F days a particularly inconvenient truth.

This historical context is frequently omitted from mainstream reporting, which tends to focus on the hot year or heatwave of the moment, presented as if it were an unprecedented event. This is a classic tactic of building a narrative on a shaky foundation of isolated anecdotes rather than long-term, statistically significant trends. The data from GHCNd, which covers intervals ranging from less than a year to more than 175 years, provides the necessary historical depth to see the modern period in its true context. It reveals that the current climate, while certainly experiencing warming, has not produced the extreme high-temperature days that were a common feature of the 1930s and other periods. For those who seek truth over narrative, this data is a vital tool in separating reality from rhetoric.
