    No one knows for certain why the Clovis people and iconic beasts — mastodon, mammoth and saber-toothed tiger — living some 12,800 years ago suddenly disappeared. However, a discovery of widespread platinum at archaeological sites across the US has provided an important clue in solving this enduring mystery. University of South Carolina archaeologists found an […]

    New research using hydroclimate data suggests the onset and recovery of the Younger Dryas climate event was more gradual than thought Researchers at The University of Texas at Austin have found that a well-known period of abrupt climate change 12,000 years ago occurred rapidly in northern latitudes but much more gradually in equatorial regions, a […]

    A period of rapid, intense cooling, known as the Younger Dryas, took place about 13,000 years ago. Scientists think this sudden change in climate caused the extinction of many large mammals, such as the mammoth, and was the reason for the disappearance of North America’s Clovis people. According to one hypothesis, a cosmic impact caused […]

    Herds of wooly mammoths once shook the earth beneath their feet, sending humans scurrying across the landscape of prehistoric Ohio. But then something much larger shook the Earth itself, and at that point these mega mammals’ days were numbered. Something – global-scale combustion caused by a comet scraping our planet’s atmosphere or a meteorite slamming […]

    WUWT readers may recall this recent story: New evidence of Younger Dryas extraterrestrial impact The story below provides much more detail about the Younger Dryas event and the split that has developed in the scientific community over the cause. I’ve added this graph below from NCDC to give readers a sense of time and magnitude of the event. […]

    A team of scientists from South Africa has discovered evidence partially supporting a hypothesis that Earth was struck by an asteroid 12 800 years ago, leading to global consequences including climate change, and contributing to the extinction of many species of large animals at the time of an episode called the Younger Dryas. The team, […]

    Our ancestors survived the ups and downs of glacial period temperatures, as well as the heat of the Eemian interglacial. Bottom line: all this climate catastrophe hype is simply hot air. Humanity may go the way of the dodo but it will be for reasons other than the C02 we are putting into the atmosphere. Worrywarts […]

    For the first time, a dramatic climate shift that has long fascinated scientists has been linked to the impact in Quebec of an asteroid or comet, Dartmouth researchers and their colleagues report in a new study funded by the National Science Foundation. Using a binocular microscope, Dartmouth geochemist Mukul Sharma examines impact-derived spherules that he […]
