The Earth…Currently In The Middle of An Ice Age…Really

This is a most shocking fact about climate change. When the Earth is not experiencing an Ice Age, there is no ice at the poles. Currently there is ice at the poles on Earth, so we are still in an Ice Age.

The current Ice Age is called the Pliocene-Quaternary glaciation, and started over 2.5 million years ago! Smaller cycles of heating and cooling also occur, and cause glaciers and ice sheets to retreat and advance within the larger time period of Ice Ages. These are called interglacialand glacial periods. These periods last from 40,000 to 100,000 years.

Currently, we are in an interglacial period where the sheets of ice on Earth have largely retreated to the poles. The last glacial period ended about 10,000 years ago. Glacial and interglacial periods are still part of climate change. However, Ice Ages occur over a much longer period of time. The interglacial period we are currently in is called the Holocene.
