Record-breaking temperatures and prolonged drought have led to the reemergence of the sunken village of Kallio in Greece's main reservoir, Lake Mornos. The village, submerged in the late 1970s to create a water supply for Athens, is now visible as water levels have dropped by 30-40 meters. This situation reflects the severity of Greece's current water crisis, exacerbated by the warmest winter on record and successive summer heatwaves. Local authorities and environmental groups are alarmed, warning that if winter rains do not replenish the reservoir, the situation will worsen. The reappearance of Kallio underscores the broader impact of climate change on water resources in the region.
