We’ve done orbital tests before and while the effects are more than we expected, they are not continent crippling or climate destabilizing.
about 900 miles (1,450 km) away from the detonation point, knocking out about 300 streetlights, setting off numerous burglar alarms, and damaging a telephone company microwave link. The EMP damage to the microwave link shut down telephone calls from Kauai to the other Hawaiian Islands.
It’s definitely not good, and there’s a reason we all agreed not to do that anymore, but it’s really more about the damage it does to satellites that hurts everyone, and the damage being too unstructured to be worth investigating too far.
That’s a bit overblown.
