we're also in an extreme solar minimum, remember.

i understand that this is a lot of 'splainin' for one volcano. i'm not trying to explain this specific volcano, so much as i'm trying to present it as representative of a broader pattern.

so, maybe it's evil republicans killing heathens at christmas. or, maybe it's the sun. i dunno.
