This file collection contains the scripts, intermediate data, and some images associated with my publication. In detail the file contains: -- compute_global_mean_temp.pro: This IDL script will trawl through a CMIP6 mirror archive (you need to adjust the path for it to work remotely) and find the ts, tas, siconc, siconca, and land fraction variables. It will then compute global mean temperature as (f + s)tas + (1 - f -s)ts, where f is the land fraction and s the sea ice fraction. It will go through the historical, hist-GHG, hist-aer, hist-nat, hist-sol, hist-volc, hist-totalO3, and hist-nolu experiments for that. Make sure to populate the archive with these data before executing the script, e.g. using synda. -- display_GMST_werror_version2.pro: This script will upload the global- and annual-mean data, conduct the regression analysis, produce plots, and store the results in a text file coefficients.txt -- calculate_statistics_new1.pro: This script will read coefficients.txt and produce figure 4 (the emergent-constraint plot). -- global_temp_allsims_ .nc: NetCDF files containing the global- and annual-mean surface temperature evolutions for all 16 models and ~1000 simulations making up the record. -- HadCRUT.5.0.1.0.analysis.summary_series.global.annual.csv: A comma-separated-values (CSV) file of the HadCRUT5 data. -- f*.eps: The figures appearing in the paper.
