In 1968, a glaciologist from Ohio State University named John Mercer wrote a paper about the dangers of the Antarctic ice sheet melting. He studied data from glaciers and dry lakes that had evidence of once being submerged and concluded that there must have been a time when all that ice melted, about 120,000 years ago. Then, he argued that it could happen again. The ice could melt and sea levels could rise drastically.
The idea of a hole in the ozone layer, then global warming, and then climate change causing ice sheets to melt is clearly not new. This idea has been around for a long time, but it didn’t really gain momentum until the 1970s. That’s when satellites were first used to measure ice, and ice loss could be definitively shown. In the 1990s, the melting of the ice sheet covering Greenland increased dramatically, doubling the rate it had experienced since the 1960s. Continue reading

Japanese companies have shown keen interest in contributing to the development and operation of airports in Indonesia, particularly Sultan Aji Muhammad Sepinggan Airport in Balikpapan. During the Air Transportation Working Group (ATWG) event held from January 18 to 20, 2024, the Ministry of Land, Infrastructure, Transport and Tourism (MLIT) shared that four Japanese companies—Japan Airport Terminal Co. Ltd, JALUX Inc., Taisei, and SECOM Co. Ltd—are eager to collaborate in this venture. These companies boast extensive experience in constructing and managing major airports in Japan, such as Haneda Airport and Narita Airport, along with international projects like Beijing International Airport in China and New Ulaanbaater Airport in Mongolia.
