Record-high heat soars through South Korea.
A record-high heatwave is sweeping through the Korean Peninsula, sending temperatures skyrocketing, reaching 42.5C.
Background
Heatwaves are now the most reliably attributable form of extreme weather, because the physics is straightforward: a warmer baseline makes a given temperature record easier to break. In humid coastal climates such as the Korean Peninsula's, the danger is not the headline figure alone but the combination of heat and humidity, which prevents the body from cooling through sweat. The people who die in heatwaves are overwhelmingly older, ill, or working outdoors, and most deaths happen indoors in housing that cannot be cooled.
Why it matters here
That last point is the one that travels to Kibra. A large share of housing here is roofed in iron sheet, with little insulation and limited ventilation, and indoor temperatures on a hot afternoon are considerably higher than the shaded reading a weather station records. Kenya's heat risk is discussed mostly as a drought and agriculture story, and much less as a housing and public health one, even though the second is what harms people in dense urban settlements.
What to watch next
Whether the heatwave produces an excess mortality figure, and whether heat is treated in Kenyan planning as a housing and health issue rather than only an agricultural one.
