The science on this is relatively recent, but it turns out there is a photomolecular effect on evaporating water that can’t be explained with heat.

Not quite sure how this would affect melting ice cream. It does fill in some missing pieces to climate models. There are more clouds around than the models predict, which raises the planet’s albedo.
