An enormous impact crater has recently been discovered on Greenland. The crater is 19 miles wide.

The Younger Dryas event

The effect of the impact can be seen 12,000 year old in ice core samples, which means that the event happened during the Younger Dryas.

This ties up well with what we already know about the Younger Dryas. A period marked by a sudden drop in temperature.

As a consequence, a large number of animal and plant species disappeared.

This happened at the end of the great ice age.

Temperatures were rising rapidly. But the Younger Dryas event reversed this trend for hundreds of years before the warming trend got back to normal.

120,000 year climate cycles

We know that Earth’s climate goes through cycles of about 120,000 years.

The pattern is the same every time. Earth cools down slowly over tens of thousands of years. Then there’s rapid warming from a minimum which takes less than ten thousand years to complete. This is then followed by about twenty thousand years of stable high temperatures before a new prolonged period of cooling sets in.

The repeated pattern of sharp temperature rises followed by prolonged cooling can be attributed to galactic super-waves. However, the sudden reversal we went through during the Younger Dryas must have been due to something else.

A meteorite impact has been proposed as a possibility. But this has been but a hypothesis until now.

Massive impact crater

The impact crater is so large that its effect must have been felt globally. There must have been earthquakes and tsunamis. Not only in the arctic, but in far away places as well. There may even have been a short lived pole reversal.

This in turn may be the source of many legends about extraordinarily large floods, earthquakes and volcanic eruptions.

It appears that we finally have concrete evidence in support of many theories related to what exactly happened during the Younger Dryas.
