Resolves positive if Bjørn Lomborg (i.e. "the" Bjørn Lomborg) appears on EAG London 2023 swapcard. Will not resolve positive if it was a temporary bug, glitch or hack. Resolves ambigious if the event does not occur.

Background info: I have no particular reason to think that Bjørn Lomborg would attend EAG London 2023. Bjørn Lomborg has not attended any of the following: EAG London 2022, EAG London 2021, EAG SF 2022, EAGxPrague 2022, EAGxBerlin 2022, EAGxVirtual 2022
