Korean media:Korean Peninsula is affected by global warming, high temperature and precipitation increase
People’s Daily Online, according to the”2020 South Korea Climate Change Assessment Report” (hereinafter referred to as the”Report”) jointly issued by the Korea Meteorological Agency and the Ministry of Environment on July 28, the issue of global warming has become increasingly severe in recent years. The average temperature and sea level rise rate exceeded the global average. According to analysis by relevant sources, it is expected that by the end of the 21st century (2071-2100), the number of high temperature days in South Korea will increase by 3.5 times, while precipitation will increase by 13.1%, and the domestic environment will not be suitable for planting apples.
The Korean media”Seoul Economy” quoted the report as saying that from 1880 to 2012, the global average surface temperature increased by 0.85℃. From 1912 to 2017, South Korea’s surface temperature rose by about 1.8°C, much higher than the world average. According to South Korea’s current greenhouse gas emissions, by the end of the 21st century, South Korea’s surface temperature will rise by 2.9-4.7°C. The report shows that after the 1970s, the number of hot days on the Korean Peninsula increased by 0.89 days every 10 years, and the number of tropical night days in summer (the lowest night temperature was above 25 degrees) increased by 0.96 days. According to the current trend of greenhouse gas emissions, entering the second half of the 21st century, the number of high temperature days in South Korea will increase 3.5 times, from 10.1 days per year to 35.5 days.

According to reports, from 1912 to 2017, the average annual precipitation in South Korea increased by 11.6 mm every 10 years. Among them, the summer precipitation increased significantly. Specifically, in South Korea, summer rainstorms (24-hour precipitation of 80 mm or more) precipitation increase by 7.54 mm every 10 years, and the time of concentrated rainstorms increases by 0.07 days every 10 years. It is estimated that by the end of the 21st century, precipitation on the Korean Peninsula will increase by about 3.3%-13.1%. At the same time, from 1977 to 1994, the average wind speed of typhoons on the Korean Peninsula was 73.9 meters per second, which occurred 22 times a year. However, between 1995 and 2012, the average wind speed of typhoons on the Korean Peninsula increased to 76 meters per second, and their frequency increased to 26 times a year.
According to the analysis of the report, according to the climate change situation, the flowering period of Korean cherry blossoms will be 11.2 days ahead of schedule. By the 1980s, Korean pine forests will decrease by 15%. The environment and climate will no longer be suitable for the growth of apples, and crops such as rice, corn and potatoes will also decrease year by year. Citrus will only be cultivated in areas north of Gangwon Province. The plant growth and development time will also be advanced by 2.7 days every 10 years, the defoliation time will be delayed by 1.4 days, and the growth and development period will be extended by 4.2 days.
