i’m learning we are situated in an unusual spot here. the ground is not terribly wet, but it definitely was in the past. the black willows here are 60 feet tall, and have trunks 3ft + across. that isn’t terribly common. the wikipedia entry shows the average black willow which is more shrub-ish. but we border wetlands, so they definitely have roots down to the water table.
blah blah blah, anyway, the point is, ive always noticed when walking under them, it’s unusually cool under them. like more than just shade cool. its weird. wondered if it had something to do with evaporation, as thats the only thing i know which pulls heat out of the air naturally. so, i threw a bunch of hypotheticals at AI, and it came back with:
the trees must be pretty old.
black willows that size can pull a couple hundred liters of water out of the ground per day, and evaporate the water into the air around it, creating a humidity bubble. but also acting like a giant refrigeration pump, keeping the air around the tree cooler, using the evaporation effect.
i just think the way He designs stuff is super amazing
