Figure 1a (the leftmost subfigure in TFA’s lead image) shows the data for Uzbekistan from the DOSEv1 dataset (green), DOSEv2 dataset (red) and World Bank (black). The authors of the retracted study used the DOSEv2 dataset in order to model climate effects on the economy at a sub-national level, as opposed to the country-level analyses used in prior work. However, it looks like the DOSEv2 data was just bad for all 14 provinces in Uzbekistan (a 90% drop in GDP for all provinces in 2020!). The typical correlation between weather and the economy is going to be fairly noisy across the dataset, but if you have 14 extra datapoints all saying there’s a catastrophic GDP crash in one year together with some coincidental weather effect, that’s going to bias the model hard. Notably, they also extrapolate losses forward all the way to 2100, so the effects of such a bias will compound.
