Extreme heat is disrupting electronics manufacturing, supply chains, and worker productivity worldwide. Heat waves are straining power grids and data centers critical to electronics production. This week’s three reads span the science of heat waves, how rising heat is reshaping workforce protection ahead of a looming “super El Nino,” and how extreme heat impacts the power grid that the electronics supply chain relies on to function. Too Hot for Work: Why Extreme Heat Is a Threat to Europe’s ProductivityThis article reports on how record heat is forcing European employers, including factories, construction sites – and breweries –to rethink schedules, breaks, and cooling measures. Extreme heat doesn’t just affect the local community or factory — it cascades through the same electrical infrastructure that data centers and electronics manufacturing depend on to keep running.
