9000-Year-Old Bison Mummy Discovered After Being Frozen at the End of the Last Ice Age

Scientists have discovered the complete body of a 9,000-year-old bison within Eastern Siberia.

Three Abrupt Pulses of Carbon Dioxide May Have Melted the Last Ice Age

What caused the end of the last ice age more than 10,000 years ago? It turns out that it wasn't a gradual process. Instead, scientists have found that three abrupt pulses of carbon dioxide may have ended the cold snap during that time period.

Icebergs Once Drifted as Far South as Florida During the Last Ice Age

Using a high-resolution model to describe ocean circulation during the last ice age about 21,000 years ago, scientists have found that icebergs from the North American ice sheet floated as far south as Florida.

Global Sea Levels Rose More Than 5 Meters Per Century After Ice Ages

Global sea level rise isn't just something we're dealing with in the present day. Scientists have now found at the end of the last five ice-ages, global sea-levels rose at rates of up to 5.5 meters per century.

Warm Gulf Stream Kept Flowing Even During the Last Ice Age

It turns out that the Gulf Stream, the warm North Atlantic current that flows into the Nordic seas, wasn't all that affected by the last Ice Age. Scientists have found that this current continued to flow, despite previous theories that it actually ceased to function.

Ice Sheet Fluctuations Can Cause Abrupt Climate Change in a Warming World

It turns out that even small fluctuations can trigger an abrupt climate change. Scientists have discovered that small changes in the sizes of ice sheets during the last ice age were enough to set off a warming event.

Drifting Continents Caused the Quaternary Ice Age 2.6 Million Years Ago

What caused the ice age 2.6 million years ago? Scientists may have just answered that question. They've found out a major new theory that explains why an ice age covered large parts of the Northern Hemisphere.

Ancient, Slowing Ocean Currents May Have Triggered Longer Ice Ages

About 900,000 years ago, ice-age cycles became longer and more intense, switching from 41,000-year cycles to 100,000-year cycles. For years, scientists have been puzzled exactly why this was the case, but now they may have uncovered the answer.

Arctic Animals from the Ice Age May Have Evolved in High Tibet

Scientists have found that evolution of present-day animals in the Arctic region may be intimately connected to ancestors that first adapted to the cold in the high altitude regions of the Tibetan Plateau.

Climate Change Didn't Cause the Mass Extinction After the Last Ice Age--Humans Did

Climate change may not be behind an extinction event that occurred around the time of the last Ice Age. Instead, humans may be to blame.

What Caused the Last Glacial Maximum? Ice Age Climate Puzzle Solved

During the Last Glacial Maximum, our planet's northern continents were covered in vast ice sheets, and carbon dioxide levels were well below levels seen before the Industrial Revolution. Now, though, scientists are uncovering exactly why the LGM occurred.

Comet Impact Theory at the End of the Ice Age is False

At the end of the Ice Age, there was a return to near glacial conditions called the Younger Dryas. While some sicentists believed that it was caused by a comet hitting Earth, though, new evidence reveals that something else must have happened entirely.
