Would an OP143 be OK then ?

What stopped in 1998 wasn't the global warming, it was their thought process. Non-paywalled version straight from the NOAA: https://www.noaa.gov/news/its-official-july-2021-was-earths-hottest-month-on-record Prediction: we're not going to get a July update from the troll. (we'll probably get an update in October or something, saying "today was cooler than yesterday, ha!")

Strictly speaking, he's right. Actually, strictly speaking, there is no skydiving canopy that has a Schumann planform. The "original" (for lack of a better word) Schumann planform is a planform for gliders, with very high ellipticity on the leading edge (towards the wingtips), and a straight trailing edge. Gliders have wings that have a much longer span than any skydiving canopy, so no skydiving canopy can have a Schumann planform, if we are strict with the terms. But if we abuse the term and apply to "high ellipticity on the leading edge and straight trailing edge", I think it is not bad if we abuse it a bit more and apply it to "high ellipticity on the leading edge and straight-ish (as compared with the leading edge) trailing edge". And that applies to all the canopies I listed, if I am not mistaken.
