1976: A magnitude 6.4 earthquake strikes the Friuli region of Italy. The human toll is heavy: the catastrophe affects 80,000 residents, causing 989 deaths and leaving 45,000 survivors homeless. This disaster remains one of the deadliest earthquakes in the modern history of Northern Italy, leaving a lasting mark on collective memory and crisis management policies.

2019: The Mauna Loa Observatory in Hawaii detects a carbon dioxide (CO2) concentration crossing the symbolic threshold of 415 ppm. This figure had never been reached since the emergence of Homo sapiens. This record measurement, recorded above the Pacific clouds, acts as a global alarm signal, confirming the profound and unprecedented alteration of our atmosphere by human activities.
