Younger Dryas

The Younger Dryas was the last ice age caused by a mile-wide iron meteorite containing iridium that hit the Hiawatha glacier leaving a 19-mile wide crater in northern Greenland. An iridium rich layer was spread over vast areas of the Earth that is now found in soil layers that links the date of this event to around only 12,900 years ago. The Younger Dryas period is so named after the alpine-tundra wildflower Dryas octopetala that first began to grow as conditions warmed up and its pollen can be detected in more recent soil layers.

Caveman Ug: When did that mile-deep ice sheet suddenly appear? It wasn’t there last month.
Caveman Ah: It was nice and warm until that bright fiery dragon flew across the sky and now it is cold enough to freeze a mammoth.
Caveman Ug: Put that fire out!
Caveman Ah: Why?
Caveman Ug: Because it will eventually lead to our extinction.

Naughty boy: Every 10 years for the last 50 years we have been taught that we have only 10 years to save the planet. Do we only have another 10 years? I looked at the global warming graph and it showed a steady warming of 0.4 degrees every 100 years during an interglacial period until Al stuck a hockey stick on the end. Then I looked further back in history at the last ice age and discovered the Younger Dryas. Now that is what I call climate change.

Teacher: Did you say younger dry ass? Now bend over…
