In response to Sias, who works for the state meteorology company Metsul, world warming is upsetting an ever higher variety of pure disasters. "There may be definitely a relationship" between the heavy rains and the cliff collapsing, Sias advised AFP. "It's a indisputable fact that the lengthy and intense interval of rains generated an infiltration of water within the rocks that triggered the rocks to maneuver and the autumn of the cliff face," he stated.
