Although future #warming will affect #vegetation, the big draw of this paper is the specific impact on #urban #forests. However, I would take quantitative estimates made with these #models with a grain of salt since they don't provide "true" urban climate signals. [1/n]
The study uses projections from 10 Global Climate Models (#GCMs) over 164 #cities; comparing modeled variables relevant to species survival against baseline values to predict future risk. A big issue is that most of these GCMs do not represent cities in any meaningful way. [2/n]
Several of the GCMs do not have explicit urban land cover or use simplified slab models. The former provides no urban-specific signals and the latter overestimates urban warming. More importantly, around half of the models use versions of the Community Land Model (CLM). [3/n]

@GlobalChangeBio 1 - Amazonian #vegetation is not only determined by climate. As such, Koppen-Geiger climate zones can lead to wrong assumptions, such as characterizing all the southern part of the basin as savannas instead of forests. 
@GlobalChangeBio 2 – The Amazon Basin does not have a single precipitation pattern or a single dry season – there are marked spatial differences that are essential to be considered when studying #fires in the region.
