Query on the new CMIP7 emissions data

[Tom Harris]

Hi,

Can anyone in this group help?

I've downloaded the data that was linked in the Van Vuuren paper. Page 2652 says:

 Data on the figures is available at Zenodo: https://doi.org/10.5281/zenodo.14382495 (Sanderson and Smith, 2025).

However when I plot the raw emissions data in the file I get different results to the data shown in figure 2 of the paper. I'm not running any models, simply plotting the CO2 emissions and GHG emissions from the file: extensions_1750-2500.csv from the data/emissions folder.

I've attached the comparison. 

I've emailed the lead author but not had a response - probably very busy fending off nonsense about SSP5-8.5.

Can anyone in this group point to where the real data might be available for the figures in the paper? Since this is the data that feeds into the new CMIP7 models, it must be widely published...

Thanks,

Tom

Hi again,

Not to worry, apparently the graphs in the paper are for illustration purposes as the final sets had yet to be completed when it went to press. 

If your interested, the files are also on GitHub at: https://github.com/chrisroadmap/cmip7-scenariomip/blob/main/environment.yml 

Cheers,

Tom
