AI synopsis

What people are saying

The discussions reflect high interest and engagement with examples like the revision of the crater's age from thousands to millions of years, and debates about its possible effects on climate and historical impact events. Tone varies from excited to analytical, emphasizing the importance of this revision in understanding Earth's geological history.

AgreementModerate agreement

Most discussions agree with the new dating of the impact structure to 58 million years, refuting earlier notions of a recent origin, indicating consensus or strong support.

InterestHigh interest

The discussions show high curiosity, especially about the implications of dating the crater to the Paleocene, seen in phrases like 'finally managed to date' and 'many riddles left,' which convey enthusiasm and engagement.

EngagementModerate engagement

Many comments reference specific research findings, methods, and implications, such as mentions of 'Argon Dating' and debates about links to the Younger Dryas, demonstrating deep engagement.

ImpactHigh impact

The discussions highlight the significance of the findings in revising impact history and their disconnect from previous theories about recent impacts influencing climate events, indicating high impact.

Hiawatha Crater has nothing to do with the Younger Dryas; recent analyses date it to over 50 million years earlier. All the evidence is compatible with solar outbursts at the beginning and end of the Younger Dryas. #YounerDryas #Impact #Sun #SolarOutburst https://t.co/SvqZgLR3Nx

Our new article on Hiawatha impact structure's age is out! Much older (~58 Ma) than we initially thought and occurred during a broader upheaval in global climate. Low long-term erosion but maybe faster now? Overlying ice still weird. Many riddles left! https://t.co/qz8Je7rV8I https://t.co/LW8lP5Gmhv

Another update: In March, 2022, the Hiawatha crater was dated. The age? Older than 13,000 years ago. Much, much older. Like, 58 million years older: https://www.science.org/doi/10.1126/sciadv.abm2434

Our new article on Hiawatha impact structure's age is out! Much older (~58 Ma) than we initially thought and occurred during a broader upheaval in global climate. Low long-term erosion but maybe faster now? Overlying ice still weird. Many riddles left! https://t.co/qz8Je7rV8I https://t.co/LW8lP5Gmhv

#VillumFellow Michael Storey and his Quaternary Argon Dating Lab at the National History Museum of Denmark has contributed to the dating of the giant Hiawatha crater under the Greenland ice. It turns out to be much older than expected, 58 million years. https://t.co/VFNGFx2tbq https://t.co/42ortO6zPK

The 31-km Hiawatha crater in Greenland was previously suspected to be the cause of the Younger Dryas, but a new study dates it to 58 Mya. Jay Melosh would be saying “See, I TOLD you a crater that big isn’t 12,000 years old!” https://t.co/eN2mY1agrt
