Latest Younger Dryas Stories
A new study published in The Journal of Geology provides support for the theory that a cosmic impact event over North America some 13,000 years ago caused a major period of climate change known as the Younger Dryas stadial, or “Big Freeze.”
A new study of three ice cores from Greenland documents the warming of the large ice sheet at the end of the last ice age – resolving a long-standing paradox over when that warming occurred.
There has been quite a bit of controversy in the scientific community regarding what might have initiated the Younger Dryas event—including one that has the event caused by a comet impacting the Earth.
The role of the hydrological cycle during abrupt temperature changes is of prime importance for the actual impact of climate change on the continents.
A new study has found that a cataclysmic asteroid or comet impact in the Canadian province of Quebec nearly 13,000 years ago wiped out many of the world’s large mammals.
One of the deepest ice cores ever drilled in Antarctica is revealing some interesting evidence about the southern continent’s turbulent past and the role Earth’s orbit played in the history of the ice ages.
Climate scientists have long debated whether floodwaters from melting of the Laurentide Ice Sheet flowed northwest into the Arctic first, or east via the Gulf of St. Lawrence to weaken ocean thermohaline circulation and have a frigid effect on global climate.
New research, led by the University at Buffalo, is examining an important mystery surrounding climate change: How quickly do glaciers melt and grow in response to shifts in temperature.
Ice samples that profile Greenland glaciers have long been used to give climate scientists historical temperature data, but those samples could be misleading.
A 16-member international team of researchers that includes James Kennett, professor of earth science at UC Santa Barbara, has identified a nearly 13,000-year-old layer of thin, dark sediment buried in the floor of Lake Cuitzeo in central Mexico.
