Precipitation and temperature timings underlying bioclimatic variables rearrange under climate change globally

Modeling how climate change may affect the potential distribution of species and communities typically utilizes bioclimatic variables. Distribution predictions rely on the values of the bioclimatic variable (e.g., precipitation of the wettest quarter). However, the ecological meaning of most of these variables depends strongly on the within-year position of a specific climate period (SCP), e.g., the wettest quarter of the year, which is often overlooked. Our aim was to determine how the within-year position of the SCPs would shift (SCP shift) in reaction to climate change in a global context. We calculated the deviations of the future within-year position of the SCPs relative to the reference period. We used four future time periods, four scenarios, and four CMIP6 global climate models (GCMs) to provide an ensemble of expectations regarding SCP shifts and locate the spatial hotspots of the shifts. Also, the size and frequency of the SCP shifts were subjected to linear models to evaluate..., , , # Data from: Precipitation and temperature timings underlying bioclimatic variables rearrange under climate change globally

## Description of the data and file structure

Format: RData
The dataset contains the processed data (SCP shifts) and some auxiliary files and script.

### 1 Global raster template

RData file called `global_raster_template.RData` that contain a `RasterLayer` object called `global_raster_template`. It is a 0-layer global raster at 2.5' (~5 km) resolution using WGS-84 coordinate reference system. The raster can be used as a template for converting the numeric vectors of the SCP shifts to rasters (please refer to the example script).

### 2 Mask of the terrestrial cells

RData file called `mask_of_terrestrial_cells.RData` that contain a logical vector called `mask_of_terrestrial_cells`. It is `TRUE` for terrestrial cells and `FALSE` for marine cells of the global raster template. SCP...,
