A record-warm summer likely accelerated the already rapid melting of Italy's high-altitude glaciers, revealing long-frozen artifacts.

Wasn't on my "apocalyptic outcomes of melting permafrost" bingo card.

In WW2 at least a subset (like 1%) of dropped bombs (not shells) had a random timer and only exploded once that ran out. This was to ensure detonations occured even hours after a bombing raid.

Those timers were based on acids dissolving something inhibiting the detonator. As such they were quite unreliable, especially if they buried themselves into the ground at certain angles.
