Are we coming to the end of an ice age?

So, in fact, the last ice age hasn’t ended yet! Scientists call this ice age the Pleistocene Ice Age. It has been going on since about 2.5 million years ago (and some think that it’s actually part of an even longer ice age that started as many as 40 million years ago). We are probably living in an ice age right now!

How long will it be until the next ice age 2020?

Researchers used data on Earth’s orbit to find the historical warm interglacial period that looks most like the current one and from this have predicted that the next ice age would usually begin within 1,500 years.

What would happen if the polar ice caps melted?

If all the ice covering Antarctica , Greenland, and in mountain glaciers around the world were to melt, sea level would rise about 70 meters (230 feet). The ocean would cover all the coastal cities. And land area would shrink significantly. Scientists are studying exactly how ice caps disappear.

Are we living in an Ice Age right now?

Striking during the time period known as the Pleistocene Epoch, this ice age started about 2.6 million years ago and lasted until roughly 11,000 years ago. Like all the others, the most recent ice age brought a series of glacial advances and retreats. In fact, we are technically still in an ice age.

Will the northern polar ice cap melt completely?

Conversely, during warm periods, the ice sheets retreated, and may not have existed at all. The current trend of global warming will cause the northern polar cap to melt entirely within a hundred years. For more on the history of Earth’s polar ice caps click here. Return to the Astronomy Workshop

How do melting polar ice caps affect the Earth’s rotation?

Another interesting effect is that, if polar ice caps are melted, that will impact the rotation of Earth and may, in fact, change how long the day is. The ice sheets, he explained further, are near the axis of the Earth’s rotation.

How long will it take for the ice caps to melt?

The Good News The expert may have described the polar ice caps melting effect a bit apocalyptic but he said that the good news is that it will take thousands and thousands of years for the entire polar ice caps to completely melt. He added the whole world is not going to end in 2121.

How important is the sea ice cover in polar climate?

The sea ice cover is one of the key components of the polar climate system. It has been a focus of attention in recent years, largely because of a strong decrease in the Arctic sea ice cover and modeling results that indicate that global warming could be amplified in the Arctic on account of ice-albedo feedback.
