If you want to be considered a serious scientist, I suggest you drop the troll technique of answering all questions with ad hominem attacks. It’s a dead giveaway.
I was interested in a genuine scientific discussion but it seems that probably won’t happen here.
Sad.
Microwave photons have less than a millielectron volt of energy, but it takes several volts of energy to ionize an atom of air. Microwaves are not considered ionizing radiation.
Now, it is true that a strong enough beam could ionize air by a multiphoton process, however a microwave beam strong enough to do that would also make the air opaque to microwaves and hence become useless for radar. So, we can presume the microwaves aren’t strong enough to do that.
Also if the beams were strong enough to do that you would see sparks and plasma, like the grape plasmas of youtube fame. But, no such plasmas are seen around the radar dish, where the electric fields are much higher than they would be miles away in the clouds where they could potentially modify the weather, or worse, around the feedhorn, where the electric field is much higher still than where it leaves the dish reflector.
The OP article is absurd.
“I was interested in a genuine scientific discussion but it seems that probably won’t happen here.”
Then why did you post this click-bait trash?
