"Endangers global security" often is treated as equivalent to "endangers the status quo", especially by the organizations and people who are powerful right now and so usually benefit from whatever the current situation is, as opposed to those who feel they lack power and thus are motivated to shake things up with a hope of ending up at the top afterwards.

And change tautologically does endanger the status quo. So proceeding with business as usual with perhaps a slow gradual shift would always be seen as the safe choice, and rapidly abandoning oil would be perceived as dangerous, no matter what harm or risks oil is causing.
