Hello from the outside: heat domes impeding radio and other signals in US midwest

A heat dome over the US Midwest has caused unexpected disruptions in radio and TV signals, even in the absence of any severe weather. The phenomenon occurs because higher temperatures can warp the atmosphere, altering how these signals travel and sometimes making them reach places far beyond their intended destination. This has led to false alarms and confusion, as seen when an outdoor emergency alarm went off in Indiana with no actual emergency present. Such disruptions highlight the broader implications of climate change on everyday technology and communication systems.
