The Pleistocene epoch is a geological time period that includes the last ice age, when glaciers covered huge parts of the globe. Also called the Pleistocene era, or simply the Pleistocene, this ...

To compare those two time periods with the present day, ... The researchers conclude that we narrowly missed an ice age off-ramp in the past few thousand years because CO 2 was just a touch too high.

Between these two ice-age periods, other ice ages occurred at 2,400–2,100, 715–550, 450–420 and 360–260 million years ago. These six major ice ages lasted between 300 and 30 million years ...

The period we live in now, called the Holocene, began some 11,700 years ago when the last ice age ended. It's known as an interglacial period, or a time between ice ages.

During the present ice age, glaciers have advanced and retreated over 20 times, often blanketing North America with ice. Our climate today is actually a warm interval between these many periods of ...

Beginning around 2.5 million years ago, Earth entered an era marked by successive ice ages and interglacial periods, emerging from the last glaciation around 11,700 years ago. A new analysis ...

The planet was on track to have an ice age in some 50,000 years, which would have already resulted in an unusually long period of warmth. Increasing levels of man-made greenhouse gasses have ...

In a nutshell Stone Age humans mastered fire technology during Earth’s harshest climate period 23,000 years ago, creating hearths that reached temperatures of 600°C—comparable to modern ...

The Quaternary Ice Age has lasted 2.5 million years so far. It's 10,000 to 15,000-year warm patches are separated by glacial periods that last several times as long as.

Over time, however, the CO2 levels built up on the Earth from volcanic eruptions and other sources. Since the water was frozen, it was unable to absorb the CO2, which led to a period of global ...

For the last 12,000 years–since the end of the last Ice Age, ... at any point in the last 115,000 years–a fact that will be seen by future geologists who study the sediments of this time period.
