With South Korea's rainy season having ended early, residents now face the challenges of increasingly erratic weather patterns influenced by climate change.

Unpredictable Monsoons: Climate Change Alters East Asia’s Rainy Seasons
As climate change leads to inconsistent rainfall patterns, many East Asians abandon their umbrellas during the monsoon season, causing concerns for farmers and citizens alike.
As the monsoon season traditionally grips South Korea and Japan in sheets of rain during summer, its once-reliable cycles are now thrown into disarray. Choi Moon-hee, a resident of Seoul, reflects this new reality, stating, "I don’t even carry an umbrella anymore." This sentiment echoes across the region, where rain has become as unpredictable as ever. On a recent evening, a brief shower surprised Choi, who had not seen rain since the monsoon was declared two weeks prior.
The inconsistency of precipitation has prompted officials in southern South Korea and parts of western Japan to announce the end of the rainy season earlier than ever recorded. For South Korea, it was declared before the calendar's month of June had closed, a marked departure from historical patterns.
For decades, East Asia's rainy season lasted from mid-June to July, driven by a stationary weather front, but alterations connected to a warming climate have resulted in significant shifts since the late 1990s. Many meteorologists attribute this deterioration in weather patterns to climate change, which has already been linked to more extreme weather events worldwide.
This shift resonates beyond South Korea and Japan, impacting neighboring India and China. In these regions, the unpredictability of the monsoon season has left millions facing unexpected floods and droughts, a consequence of changes in rainfall distribution that climate scientists are increasingly documenting. The effects not only disrupt daily life for many individuals but also pose serious risks to agricultural production and food security across East Asia.
