Precise proposition checked
Regional cool anomalies on a single monthly temperature map demonstrate that the global average and long-term human-caused warming trend are not occurring.
Full post context: A Watts Up With That? article dated August 22 in its URL and August 23 in UTC page metadata highlighted cooler July 2026 regions to imply global warming was not occurring.
Scope of this check: The check accepts that several regions were cooler than their July average. It separates regional anomalies, the global monthly mean, and the long-term trend.
What the evidence shows
Copernicus measured July 2026 at 16.90°C globally, 0.67°C above the 1991–2020 July average, tying July 2024 as the second-warmest July on record. NASA's annual record independently shows that the ten most recent years are the warmest on record.
- Cool regional anomalies were present in July 2026.
- The Copernicus global July average was 16.90°C, 0.67°C above the 1991–2020 July average.
- July 2026 tied July 2024 as the second-warmest July in that dataset.
- NASA's annual record shows the ten most recent years are the warmest on record.

What is true
Some regions, including parts of Europe and other areas shown on the map, were cooler than their July climatology. Neither one warm nor one cool month establishes a long-term trend by itself.
Where the claim fails
The argument substitutes selected regions for the area-weighted global average and substitutes one month for the long-term record. A warming climate still contains cooler-than-average places and short-term regional variability.
Limits and uncertainty
A single global month is not the long-term trend. Dataset methods and reference periods differ slightly, while the broad conclusion is tested across independent records.
Assessment after the evidence
Regional cold anomalies can occur during a very warm global month; they do not overturn the measured global average or long-term trend.
How the framing works
Spatial cherry-picking and weather-versus-climate confusion: cool patches are substituted for the global mean and long record.
How scientists know
Climate centers combine quality-controlled land and ocean observations on a global grid, calculate area-weighted monthly averages against a defined reference period, and evaluate the multi-decade record separately.
Editorial boundaries
ACC evaluates the claim. It does not infer intent, coordination, funding, deception, or control without direct evidence specific to that attribution.
