based on https://gml.noaa.gov/ccgg/trends/graph.html
an answer will resolve "yes" if there is any monthly datapoint on that graph greater than the number on the answer, up til the december 2025 reading
as of the time of posting, 425 is the maximum integer value ever reached.
if somehow co2 levels look like they might go higher than the available options, I will add more

430.51 for May 2025 so 430 can resolve @JesWolfe Thanks.

@ChristopherRandles done. I really did not thing we’d hit that one this year!

@JesWolfe Thanks.
May 2025 430.51
June 2025 429.61
Peak is always May or June so rest are near certain to be no, but not sure if you are going to wait just in case something really weird happens. Close date of March 2026 seems a bit weird, surely ~6 Jan 2026 is late enough even if not now?

@ChristopherRandles I moved the closing date into January

428.15 for March 2025 so 428 can resolve yes @JesWolfe Thanks

bought Ṁ481 YES

429.64 for April 2025 so 428 and 429 can resolve @JesWolfe Thanks
