maybe not an 'ice age' but it could get significantly colder in
the temperate-high latitudes over a very short time span. This
is observed in Greenland ice cores.
that article isn't very well written or clear.
this paragraph is pretty garbagey for example:
"Evaporation over warm, tropical and subtropical oceans
transfers water vapor to the atmosphere, which transports
it toward both poles. At higher latitudes, that water
vapor precipitates as rain or snow and ultimately returns
to the oceans, which complete the cycle by circulating
fresh water back toward the equator. The process maintains
a balanced distribution of water around our planet."
