The first one is about how wet bulb temperatures and extreme heat work. The second one is about Europe. Whether or not they are ‘more’ resilient doesn’t matter.
Also I don’t think you know what Europe is. Scandinavian, Central European and British houses are mostly made to keep heat in during cold winters. They’re not good for heatwaves.
Mediterranean style housing is definitely better for heat. But that doesn’t stop Italy, Spain, and France from having deadly heatwaves.
