Global Warming Convincer

This Idea has the purpose of targeting someone who claims Global Warming isn't a real thing. I might point out that arguments pro and con, on that subject, have been compared to Religious arguments (thus the chosen category for this Idea). We start by observing that person's "routine". Then we buy a few thousand microwave ovens, and disassemble them somewhat. We want to convert each one into a parabolic microwave-beam generator, that looks like an ordinary satellite TV dish. We place these ovens at various places and distances from the target's normal path of motion, and turn them on.

Each oven generates a beam that will weaken with distance. This is fine, and part of the reason why we locate them at reasonable distances from the target. The goal, however, is to ensure the target is always being beamed-at by a multitude of these modified ovens.

We all know that water makes up a large portion of the human body, and microwave ovens are specifically designed to generate electromagnetic waves that can be easily absorbed by water molecules. Our target will therefore become somewhat warmer than normal.

It won't matter what the outside temperature is, or how cold an air conditioning system is set, as long as the target is getting beamed by multiple modified ovens, extra warmth will be experienced by the target.

The final step is to make sure that the target is told that Global Warming is a real thing, and everyone will be affected by it sooner or later. Indeed, some might be affected sooner than others....

After the target has become convinced that Global Warming is indeed a real thing, perhaps some of the ovens can be repurposed, and aimed at a different target who needs to be similarly educated. But some of them should remain focused on the original target, just to ensure that person's mind doesn't change again.
