I hope it's not a mystery box. Just a spatial anomaly that will be explained (enough) in the next couple episodes, and then the deal is to try to figure out how to stop it or circumvent it.
Climate change or COVID are not mystery boxes, they're just disasters that require loads more teamwork than we seem to be capable of. That's, I think, where they're going with this story.
I hope that's the case. They seem to be going in the mystery box direction with the whole "why did it change direction all of a sudden" but I suppose it's too early to say. It would also be nice if this anomaly thing didn't stretch out the entire season only to be neatly wrapped up in the finale.
