We are currently in an Ice-Age.
There will be over an extended period of
time both warming and cooling periods that
are not unique in the long history of our Earth.
"The current ice age,
the Pliocene-Quaternary glaciation,
started about 2.58 million years ago during
the late Pliocene, when the spread of ice sheets in
the Northern Hemisphere began. Since then, the world has seen
cycles of glaciation with ice sheets advancing and retreating on 40,000-
and 100,000-year time scales called glacial periods, glacials or glacial advances,
and interglacial periods, interglacials or glacial retreats. The earth is currently in an
interglacial, and the last glacial period ended about 10,000 years ago. All that remains of the
continental ice sheets are the Greenland and Antarctic ice sheets and smaller glaciers such as on Baffin Island."
A very enlightening article.
All the best,
