Before the Holocene, the last glacial period lasted about 110,000 years. It is often referred to as "the last ice age" and is best known for hosting now-extinct megafauna, such as woolly mammoths (Mammuthus primigenius), giant ground sloths and saber-toothed cats. But there are m...

The ice that once cloaked the area during the last ice age has long since melted, but the Earth hasn't entirely snapped back from the burden. Since gravity over an area is proportional to the mass atop that region, and the glacier's imprint pushed aside some of the Earth's mass, gravi...

At the end of the last ice age, around 11,700 years ago, Earth’s climate began warming rapidly. As the planet heated up, its vast glaciers fell back. Almost immediately afterwards volcanic activity increased. That was nothing new. The geological record has plenty of evidence of big glacial...
after studying the oldest soils on Earth. The researchers say elements in the three-billion-year-old material show evidence for oxidative weathering. This is some 700 million years before the Great Oxidation Event when other geological data points to a dramatic rise in free O2 in the atmosphere...
The last deglaciation spanned ~20-6 ka (ka=kilo annum, or a thousand years before present) with sea level rising 125-130 m (Figure 3g) reflecting the retreat of all of the Earth's ice sheets. Sea-level rise was not constant, however, with increases above its average rate of rise of...
At the end of the last global ice age, the deep-frozen Earth reached a built-in limit of climate change and thawed into a slushy planet. Results from a Virginia Tech-led study provide the first direct geochemical evidence of the slushy planet—otherwise known as the “plu...
