How Global Warming Will Affect Short-wave Radio

1: Atmosphere heats

2: Warmer atmosphere expands

3: Upwards

4: Reflective layers in Ionosphere are pushed upwards by expanding
atmosphere

5: Higher reflective layers mean " Skip Long" for SW radio Stations..

Comments..?


If indeed the ionized layers are pushed up, it would potentially mean no
more skip for MW signals, and would likely lower the MUF for skip, resulting
in some frequencies currently usable during the day moving to nighttime use,
while current daytime frequencies could die altogether.
