I don’t know why this didn’t occur to me sooner. Even if you just use a junk account to like and subscribe it’s the cheaper version of donating.
PBS Terra, for one, has actual climate change news and science. In addition to all the other cool things, and, ofc, PBS kids.
Here’s the list: NOVA PBS official, PBS, PBS Terra, American Experience PBS, Frontline PBS Official, PBS Documentaries, PBS NewsHour, PBS kids, PBS Eons, PBS Origins, PBS SpaceTime.


They do have it on their website
Edit: they do post full episodes daily

OK but that is…not YouTube.
To watch aeveral things online requires the pbs passporr subscription. Which I happily pay.
Yeah I happily pay too, and they are full episodes on their yt channel as well
Unfortunately their website videos don’t load.
Maybe some drm thing?
