Though popular science suggest otherwise, we possess the technology to generate a "mini Carrington Event" - at least in regards to electronics and communication. Granted, we're not going to get auroras like a real cme - that's orders of magnitude beyond than what we can do, and honestly would be a waste of energy/material.

Fire and fury like the world has NEVER seen?

Even existing thermonuclear devices can optimized to generate an EMP with a peak electric field strength of tens of kilovolts per meter (or more) at the Earth's surface. With minimized kinetic results or fallout.

And these are decades old. 😁

That's all I have.
