  1. 9:55 my understanding Greenland impact was of recent, within some 50k yrs, but actual date properly disputed. Hasn't been studied long, only found in last decade. Has that changed?

  2. Not that ice drilling is easy but a core from above crater should set definitive minimum and fairly accurate actual date. (allowing for an initially hot crater for some yrs, melting snow seasonally for decades, centuries?? Simulations can determine that)
