I know it's popular to hate on the global elite and jump all over their hypocrisy at any opportunity, but we need to take a long, hand look at ourselves for a minute. There are no headlines right now proclaiming outrage over the number of people flying private jets to go on fancy vacations, but tons of headlines about people flying jets to this climate talk. It's crazy and irrational for us to scream about people using private jets for events that are trying to help the world but then ignore all the selfish personal uses of private jets that are constantly happening for more frivolous reasons.
The outcome of talks like these is tremendously important if we want to address climate change; if allowing people to spend a little extra jet fuel will help encourage better attendance and ensure the attendees feel refreshed and sharp when they arrive, then that seems like an okay tradeoff to me. The extra CO2 being emitted here really is a tiny drop in the bucket.
EDIT: Judging by the silent downvotes, I guess people would rather just cling to their blind outrage than think critically about their own reactions to these things. Disappointing.
