(or such updated location for this Gistemp v4 LOTI data)
January 2024 might show as 122 in hundredths of a degree C, this is +1.22C above the 1951-1980 base period. If it shows as 1.22 then it is in degrees i.e. 1.22C. Same logic/interpretation as this will be applied.
If the version or base period changes then I will consult with traders over what is best way for any such change to have least effect on betting positions or consider N/A if it is unclear what the sensible least effect resolution should be.
Numbers expected to be displayed to hundredth of a degree. The extra digit used here is to ensure understanding that +1.20C does not resolve an exceed 1.205C option as yes.
@ChristopherRandles Came out early? Didn't it used to come out in parallel with the global report?
Retrospectively, given that I bet the >1.205 up to ~88%, it seems I bet the higher 2 bins up too much even if the >1.205 one barely resolved YES..

Prices look odd there?
1.26C is my final prediction since all the data is in.
GIS TEMP anomaly projection (June 2024) (assuming 0 error): 1.260
Calculations for % tying for given anomaly ranges:
Error to tie monthly exceedance of 1.085 C (for June 2024): -0.175
% of years for June that have error > than the error needed to tie for exceedance of 1.085 C June 2024
(% chance of (tying or) not breaking anomaly record for June): 100.00 %
Error to tie monthly exceedance of 1.155 C (for June 2024): -0.105
% of years for June that have error > than the error needed to tie for exceedance of 1.155 C June 2024
(% chance of (tying or) not breaking anomaly record for June): 100.00 %
Error to tie monthly exceedance of 1.205 C (for June 2024): -0.055
% of years for June that have error > than the error needed to tie for exceedance of 1.205 C June 2024
(% chance of (tying or) not breaking anomaly record for June): 89.47 %
Error to tie monthly exceedance of 1.255 C (for June 2024): -0.005
% of years for June that have error > than the error needed to tie for exceedance of 1.255 C June 2024
(% chance of (tying or) not breaking anomaly record for June): 52.63 %
Looks joeover (for NO bettors on the related main market) for the rest of the month (trend is only rising temps where as ERA5 averages from 2023 trend downward).
(Does that meme work here?)
