Latest Quaternary glaciation Stories
Have you ever wondered what causes the entire Earth to freeze up and enter an ice age? According to this new study, it's not planetary wobbles like previously thought.
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.
A new study from Lund University in Sweden has, for the first time, reconstructed solar activity during the last ice age. The study shows that the regional climate is influenced by the sun and offers opportunities to better predict future climate conditions in certain regions.
A team of MIT scientists has turned to the Southern Ocean in search of an explanation for the Last Glacial Maximum (LGM), a period in the Earth's climate history during which the northern continents were covered by ice sheets.
A new study has developed crucial new information about how the ice ages came about based on newly discovered relationships between deep-sea temperature and ice-volume changes.
Using sediments from a remote lake, researchers from Brown University have assembled a 60,000-year record of rainfall in central Indonesia. The analysis reveals important new details about the climate history of a region that wields a substantial influence on the global climate as a whole.
Polarstern, a research icebreaker, returned from the South Pacific in 2010 with a scientific treasure. The treasure, described in a recent issue of Science, consisted of ocean sediments from a previously almost unexplored part of the South Polar Sea.
An international team of scientists, led by Julie Brigham-Grette of the University of Amherst, has analyzed the longest continental sediment core ever collected in the Arctic to provide “absolutely new knowledge” of Arctic climate from 2.2 million to 3.6 million years ago.
In the next few centuries, Canada's Arctic Archipelago glaciers will melt faster than ever, according to a new study. Research has revealed that 20 percent of the Canadian Arctic glaciers may have disappeared by the end of our current century, leading to an additional sea level rise of 1.4 inches.
Researchers have found that greenhouse gas concentrations similar to the present – almost 400 parts per million - were systematically associated with sea levels at least 30 feet above current levels.
