Buried in the last paragraph: “The chance of temporarily reaching 1.5°C has roughly doubled compared to last year’s predictions, said WMO. This is mainly due to using an improved temperature dataset to estimate the baseline rather than sudden changes in climate indicators.”
Knowing that a probability has doubled doesn't strike me as particularly useful here. If it doubled from 1e-6 to 2e-6, then it's still almost certain that it won't happen. If it went from 0.5 to 1.0, well, that's a different matter entirely....
