technically we are still in an ice age
from wiki - "An
ice age is a period of long-term reduction in the
temperature of the
Earth's surface and atmosphere, resulting in an expansion of continental
ice sheets, polar ice sheets and alpine
glaciers.
Glaciologically,
ice age
is often used to mean a period of ice sheets in the northern and
southern hemispheres;
by this definition we are still in an ice age
(because the
Greenland and
Antarctic ice sheets still exist). More colloquially, when speaking of the last few million years,
ice age is used to refer to colder periods with extensive ice sheets over the
North American and
Eurasian continents: in this sense, the
most recent ice age peaked about 11,000 years ago. This article will use the term
ice age in the former, glaciological, sense:
glacials for colder periods during ice ages and
interglacials for the warmer periods."
