According to one expert's calculations, climate change is causing Japan's mountains to warm usually faster than those in other countries, with the summit of Mount Fuji projected to be warmer within half a century.

The temperature changes on Mount (Mt.) Fuji in Japan was studied. The Japan Metrological Agency provided various parameters of air temperatures on Mt Fuji in Japan. On Mt. Fuji, air temperature parameters were positively correlated with years.

Furthermore, the number of days with temperatures below -24°C in January was negatively related to the year. Global warming was also demonstrated on Mt. Fuji in Japan, particularly during the winter. As a result, we must address the global warming effect.

According to Masatoshi Yoshino, professor emeritus at the University of Tsukuba and senior program adviser on environment and sustainable development, the peak of Mount Fuji will be 1.5 degrees warmer by 2050, while smaller mountains ranging in altitude from 1,100 meters to 2,000 meters will warm by 0.8 degrees.

The low-lying Pacific islands, which include Fiji, Tonga, and Samoa, are among the world's most vulnerable to extreme weather events caused by climate change.

In recent years, Fiji has been battered by a series of tropical cyclones, causing major flooding that has displaced thousands from their homes and hampered the island's economy.

"In our blue Pacific continent, machine guns, fighter jets, grey ships, and green battalions are not our primary security concerns," Fiji's Minister of Defence, Inia Seruiratu, said at the Shangri-La Dialogue, Asia's top security meeting.

The gathering, which ends on Sunday, has been dominated by discussions about Russia's invasion of Ukraine and escalating tensions between the US and China over issues ranging from Taiwan's sovereignty to Pacific military bases.

After China inked a security pact with the Solomon Islands in April, the United States, Australia, and New Zealand became concerned about Beijing's increased military presence in the Pacific.

Greenery is creeping up the formerly grey and barren slopes of Japan's Mount Fuji, with experts attributing the gradual reforestation to global warming.

According to a study published in the scientific journal Plants by Japanese scientists, the tree line on Mount Fuji has risen by up to 30 meters in the last four decades. It also mentions that larch trees, which normally grow close to the ground and follow the contours of the windswept 3,776-metre peak, are becoming more upright.

The scientific findings coincide with the unusually late appearance of snow on the mountain's upper levels, which is located about 100 kilometers west of Tokyo. Even in late December, observers noted that there was no snow on the peak, which some interpreted as a sign that magma was rising within the volcano and that an eruption was imminent.
