Climate Amnesia Explains Why Winters Feel Colder Than Data Suggests
The 'climate amnesia' theory explains why people perceive cold winters despite warming trends, though critics view it as gaslighting.

Climate Amnesia: When Real Cold Becomes Perceptual Bias
The theory of 'climate amnesia' aims to explain why many perceive winters as colder when data shows the opposite. A January 2026 article in La Vanguardia argues that human memory forgets warm events and magnifies cold ones, a phenomenon known as 'shifting baseline'. However, backlash has been swift: accusations of institutional gaslighting, skepticism regarding historical data reliability, and voices recalling harsh childhood winters.
The Scientific Argument: Milder and Shorter Winters
Data from AEMET (Spain's meteorological agency) and other bodies confirm an upward trend in winter temperatures since the mid-20th century. Persistent frosts and heavy snowfalls from past decades are increasingly rare, barring isolated episodes like Filomena in 2020. 'Climate amnesia' posits that our memory selects recent cold extremes while forgetting mild winters, creating distorted perception. Proponents note that 97% of active climate scientists accept anthropogenic warming, and local variations do not invalidate global trends.
The Visceral Response: Gaslighting or Reality?
A recurring criticism is that the concept acts as a catch-all: if it’s hot, it’s global warming; if it’s cold, you just don’t remember how bad it used to be. "If it’s freezing your ass off, you have climate amnesia," summarized a widely circulated analysis. Critics point out that winters in the 80s and 90s were objectively harsher, with frequent low-altitude snow. The Filomena episode, which paralyzed Madrid in 2020, serves as a counterexample: that record snowfall doesn't fit the narrative of ever-warming winters. Additionally, media outlets now discussing climate amnesia previously predicted perpetual snow disappearance, forecasts that did not materialize.
Historical Context: Climate Cycles and the Little Ice Age
One side of the debate places current warming within natural planetary cycles. They recall that during the Medieval Warm Period (about 900 years ago), temperatures were higher than today, and the Little Ice Age (14th–19th centuries) was a cold anomaly. Using the pre-industrial temperature of 1850 as a baseline, we were emerging from that cold period, so subsequent rise is partly natural recovery. It is also noted that between 1940 and 1975 there was a slight thermal decline, adding complexity to the linear warming narrative.
The ozone layer issue emerges as an example of how scientific narratives can shift: the 'hole' that alarmed us in the 80s is now presented as recovering, though some doubt CFCs were the primary cause. Skeptics see an obvious analogy with climate change: apocalyptic predictions often moderate over time, while new terms are introduced to justify discrepancies.
The lingering question: How much of what we feel is cognitive bias, and how much is data manipulation? Meanwhile, car thermometers still read lower than some would like, and the gap between statistical reality and individual experience widens.
