This has been suggested multiple times in the last 1-2 years or so if I remember correctly!
Let's not forget we just came out of an ice age, i.e. the Little Ice Age from about 1300 AD to 1850 AD. Naturally, things warm up again! 😊
This article is also another warning that so called climate models ought to be treated with skepsis in the past and present and overall! Climate is a very complex natural phenomenon that we still poorly understand!
Probably, too many climate scientists have a strong love affair (emotional attachment, bias) with the cute term greenhouse gases (GHG)! Almost as if GHG was self explanatory!
"... A new study, published in Geophysical Research Letters, reveals that recent European summers have been characterized by an increase in these "quasi-stationary" wave patterns, effectively trapping heat over the continent and creating what feels like a giant, unmoving heat dome. ...
For decades, sulfate aerosols from coal plants and smokestacks acted like a dimmer on the sunlight over Europe. One researcher notes these particles "have masked the warming…by just over one degree on average" in summer. But once clean-air laws kicked in and sulfates fell, "the temperature increased rapidly." ..."
From the abstract:
"Compared to observations, climate models underestimate the recent increase of European summer temperatures, due to an underestimation of Quasi-stationary Rossby Wave (QSW) trends over Europe. This is partially due to unpredictable internal variability and partially due to an underestimation of the predictable signal in response to external forcings. The analysis of a large ensemble of historical simulations shows that forcing factors generate changes in QSW and European summer temperatures consistent with those from observations but with a lower magnitude, making most of the observed changes predictable by the models through a signal adjustment.
The analysis of single forcing experiments shows a major contribution of aerosols starting from 1980, when the reduction of sulfate aerosol emissions over Europe is associated with a longitudinal temperature asymmetry, which alters the atmospheric circulation. These results further demonstrate the need to account for model errors to best estimate past and future changes in climate."

Increase in European summer heatwaves driven by greenhouse gases and amplified by aerosol emission reductions (open access; it appears there is even a second, similar paper published almost at the same time)
