    571. Causes and Effects of Extreme Weather and Climate Change

    Japan experienced a series of hot days in late June, and the Japan Meteorological Agency (JMA) has announced preliminary estimates that the rainy season has ended record early in various parts of eastern and western Japan and in the southern Tohoku region. Heat waves have been reported in many parts of the world since the beginning of this year, especially in India, Pakistan, and most of South Asia since March, with some estimates suggesting that the probability of heat waves has increased 30-fold due to human-induced climate change. In recent years, methods for rapidly estimating the causal relationship between extreme weather events and climate change have improved.

    570. Climate Change and Green Water

    A paper published in the journal Earth's Future reported that by 2050, more than 80% of the world's agricultural area is expected to suffer from agricultural water shortages. To mitigate the effects of water scarcity in future warming, it will be necessary to improve the use of green water, which is brought directly to agricultural lands by rainfall and stored in the soil, through the installation of small reservoirs.

    568. International Day of the Tropics: Initiatives to Utilize Genetic Resources and the Island Environment of TARF

    June 29th is designated by the United Nations as the “International Day of the Tropics” to celebrate the extraordinary diversity and highlight the challenges of the tropics. The tropical regions account for 40% of the world's total surface area, approximately 80% of the world's biodiversity, and the majority of the world's diverse languages and cultures. The tropics have experienced significant economic development in recent years, but with the accompanying population growth and urbanization, coupled with climate change, the region faces challenges such as the degradation of the natural environment and ecosystems and a rapid decline in biodiversity. The rich natural environment and diverse biological resources of tropical regions need to be protected as common assets of the Earth.

    566. Sea Ice Melting and Tipping Point

    The melting of sea ice in Greenland and the Arctic Ocean, along with the thawing of permafrost, the melting of the Antarctic ice sheet, and the deforestation of the Amazon, is considered one of the tipping points in the climate change debate that will involve large-scale changes and will gradually become irreversible for our planet. Averting the threat of a global emergency will require urgent science-based action and social change to curb greenhouse gas emissions.
