Sometimes it rains in Seoul and sometimes it doesn't; CO2 blamed

When climate changes, city must too - INSIDE Korea

These are all signs that a subtropical climate is creeping up the Korean Peninsula. And as Seoul saw this week, as it got hit by historic amounts of rainfall, climate change requires very real changes in cities and how they deal with the weather, such as water control systems. Because the systems in Korea’s cities were built for a bygone climate.

Two Centuries of Precipitation and Drought Data from Seoul, Korea

In viewing the results depicted above, it is obvious that the only major multi-year deviation from long-term normalcy is the decadal-scale decrease in precipitation and ensuing drought, which phenomena each achieved their most extreme values (low in the case of precipitation, high in the case of drought) in the vicinity of AD 1900. Hence, it would appear -- in fact, it is very clear -- that the significant post-Little Ice Age warming of the planet had essentially no effect at all on the long-term histories of either precipitation or drought at Seoul, Korea, which observation adds to the growing body of such findings from all around the world, as may be seen from perusing the materials we have archived under the headings of Weather Extremes (Drought and Precipitation) in our Subject Index.
