But there's nothing in the article to suggest that these events actually affected the entire world. Most of the analysis seems to have been carried out in the northern hemisphere. If one of these events happened, perhaps it'd affect only one hemisphere or we'd have portions of the world unaffected or partially unaffected and able to provide assistance.

Half the world is still very different to one country.

In fact, if the "once country" was _China_ (or Taiwan) it could be a civilisation ending event. We've built a house of cards, and while it does have some redundancy it's not all that resilient.

Keep in mind the modern world as it is now hasn't even existed 50 years, it has never really been tested with a truly international disaster.
