I remember watching a Tech Ingredients video where I think they did the math on space lasers, I think the conclusion was that it would be technically possible to significantly impact local earth surface temperature with one. (Might've been a degree or two extra for 10km² or something like that, with a huge satellite, maybe around the size of Hubble, or bigger.)

Of course, there's no reason to believe some politicians' insane ramblings about "Jewish Space Lasers".

Edit, found the video: https://youtu.be/-MVs37rxJL0?si=4Ztwq-FyOiB0uZqI

If the topic seems insane, the caveat at 31:50 should probably correct the tone. This man doesn't actually believe space lasers were used to start a big grass fire.

Also, I remembered all the numbers very wrong.
