Nepal
900+ Trapped in Tunnels
Rescue teams are working to locate over 900 missing hydropower workers in Nepal after last Wednesday’s series of devastating flash floods. The death toll has risen to 903, with 16 additional fatalities reported in Tibet, while nearly 5,000 individuals are still unaccounted for. Ongoing efforts are hampered by challenging terrain, high floodwaters, and adverse weather. The destruction of over 40 bridges has forced rescuers to use helicopters, and India and China are sending prefabricated bridges to aid access. The unpredictable course of the Trishula River caused flooding in previously dry areas, complicating rescue efforts. Infrastructure damage has caused a loss of about 700 megawatts, or 10% of Nepal’s power capacity. The flash floods were initiated by a glacial collapse in the Himalayan region that caused a torrent of water and debris to flow downstream, impacting both Nepal and Tibet.

Cyprus
Passenger Ferry Sinks
A major marine disaster occurred off the coast of Cyprus when a passenger ferry carrying 267 people capsized. The privately owned ferry left the port of Kyrenia at 12:30 PM local time and immediately started taking on water for an unknown reason. According to various sources, at least 8 people have died, and 18 passengers remain missing. The ferry capsized approximately 4 nautical miles (7.5 km) off the Turkish coast. The route between Kyrenia and Taşucu crosses a politically sensitive and heavily traveled stretch of the Mediterranean Sea. This corridor is used for daily civilian transport, tourism, and trade. Some passengers escaped through broken windows, but many did not know how to swim, leading to immediate drownings. Panic caused some to jump into the sea without life jackets.

World
Ocean Climate Link Breaks
New research provides evidence that the centuries-old influence of the Pacific Ocean on temperatures in the Indian Ocean is being disrupted by human-driven greenhouse gas emissions. Normally, changes in the Pacific Walker circulation, a system of moving air over the tropical Pacific, influences the Indian Ocean through an “atmospheric bridge.” Since the 1950s, however, the tropical Indian Ocean has warmed by about 0.1°C per decade with the increase in greenhouse gases, warming which can no longer be offset by the Pacific Walker circulation, even though it has strengthened since the 1980s. Scientists found a similar disruption in the early 1800s, when major volcanic eruptions, including Mount Tambora in 1815, temporarily cooled the planet and also altered the connection between the two ocean basins. With this unprecedented change driven by global warming, the long-term effects of Indian Ocean temperatures on rainfall across Africa, Asia, and Australia are becoming harder to predict.

Q: What is the longest river in Australia?
A: Murray River
The Murray River flows across southeastern Australia for more than 1,500 miles (2,400 kilometers). It starts near Mount Kosciusko in southern New South Wales, flowing to the west and northwest as it forms most of the boundary between New South Wales and Victoria. It then flows into South Australia, where it bends southward at Morgan. It finally empties into Encounter Bay, 40 miles (64 kilometers) east of Adelaide on Australia’s south coast. The Darling and the Murrumbidgee are the two most important rivers that flow into the Murray. Along the banks of the Murray are many wetlands. These are natural areas that support many different birds and other animals. The land in the basin formed by the Murray and Darling rivers accounts for a large share of Australia’s total farmland.
