A Massive Impact Crater Has Been Detected Beneath Greenland's Ice Sheet (gizmodo.com)

An anonymous reader quotes a report from Gizmodo: An unusually large asteroid crater measuring 19 miles wide has been discovered under a continental ice sheet in Greenland. Roughly the size of Paris, it's now among the 25 biggest asteroid craters on Earth. An iron-rich asteroid measuring nearly a kilometer wide (0.6 miles) struck Greenland's ice-covered surface at some point between 3 million and 12,000 years ago, according to a new study published today in Science Advances. The impact would've flung horrific amounts of water vapor and debris into the atmosphere, while sending torrents of meltwater into the North Atlantic -- events that likely triggered global cooling (a phenomenon sometimes referred to as a nuclear or volcanic winter). Over time, however, the gaping hole was obscured by a 1,000-meter-tall (3,200-foot) layer of ice, where it remained hidden for thousands of years. Remarkably, the crater was discovered quite by chance -- and it's now the first large crater to be discovered beneath a continental ice sheet.

Many "scientists" examinating old sites like stone henge or sites like https://en.wikipedia.org/wiki/... believe that "the flood" happened about 12000 years ago, just before the end of the ice age. The reason is that magalitic stone sites like this have astronomic properties that point to a particular point in sky. (All over the planet big monuments point to the same point).

That is the suns rising point during the spring equinox 12000 years ago, researchers believe that this is a "time reference". Many sites also show references for water or flooding, as in pictures or smaller buildings pointing to the sign of aquarius. But why that sign would be generally associated with water, I have no idea :D

Yes, I believe that the flood myths we have have a core of truth. Otherwise not every single tribe on the planet had a flood myth. And it is plausible that we once had a civilization on the level of industrialized England 1890 or so, 12000 years ago. Just look at the difference in sea level during the last ice age and now.

Australia was connected with Asia via a land bridge from Indonesia. Japan was connected north and south with China. The mediteranean sea was mostly dry land. Great Britain was connected with mainland Europe ... If there was a high level civilization somewhere and the sea level rose rapidly (and having an impact with weeks of rain) would even be havoc for our civilization today.

You need to define the something in "do something about". Most of the "somethings" that people have proposed are more expensive than they're worth and result in vast amounts of dead people in third world nations. At least, that is so according to a recent Nobel Prize winner.
