Three climbers, two Americans and one Canadian, are feared dead after going missing on Aoraki Mt Cook, New Zealand’s tallest mountain. Search efforts have been hindered by bad weather, with police believing the climbers fell while crossing a ridge. Experienced mountaineers Kurt Blair and Carlos Romero were reported missing after they failed to catch their flight. Tribute messages highlight their contributions to the climbing community. The search will now be scaled back as evidence suggests the climbers may not have survived.
