This is a 'how many' question using a yes no format where resolve probability is used for different answers.

Resolves per https://gml.noaa.gov/webdata/ccgg/trends/co2/co2_mm_mlo.txt or any updated location. If unavailable will use Scripps

https://scrippsco2.ucsd.edu/data/atmospheric_co2/primary_mlo_co2_record.html

NOAA graphs at https://gml.noaa.gov/ccgg/trends/weekly.html

As examples

January 2024 MLO level is 422.50 or lower then claim resolves at 0%

January 2024 MLO level is 422.74 then claim resolves at 24%

January 2024 MLO level is 423.50 or higher then claim resolves at 100%

Resolution will be soon after data made available [likely ~5-8 February 2024 (I think)]. Close date may be pushed back until after the data is available.
