The ERA5 global reanalysis
This paper presents a comprehensive overview of the ERA5 global reanalysis from 1979 onwards, which is produced at ECMWF as part of the Copernicus Climate Change Service. It provides a detailed...

Cherry picking this to debunk the whole climate modelling exercise is clearly a bad faith argument, but these sort of trend errors would, at face value, be a real issue for e.g. an agro sector end user and should be a focus for model development.

The issue with JJA T2m trends over the US is consistent with this paper www.nature.com/articles/s41... linking the strength of a warm/dry bias over the central US to magnitude of regional temperature change. It's a common issue and relates to convective precip and land-atmosphere coupling.
Causes of model dry and warm bias over central U.S. and impact on climate projections - Nature Communications
Climate models repeatedly show a warm and dry bias over the central United States, but the origin of this bias remains unclear. Here the authors associate this bias to precipitation deficits in models...

The key findings are:
1. Regions such as western North America, southern Europe, and Central Asia show further potential for seasonal temperature and precipitation prediction skill based on soil moisture anomalies.
