Are we about to experience the same thing again? This is a very long article and people will lose interest so....here's a youtube synopsis.

A glacier the size of Florida is on track to change the course of human civilization.

Thwaites glacier in West Antarctica is enormous and is often referred to as the most dangerous glacier on Earth. It has also been dubbed the doomsday glacier. The glacier holds two feet of sea level but more importantly, it is the “backstop” for four other glaciers which holds an additional 10-13 feet of sea level rise. When Thwaites collapses it will take most of West Antarctica with it. This is not new information for those of us that follow the science. For example, Eric Rignot in 2014, stated that the loss of West Antarctica is unstoppable. You can listen to an excellent interview from 2019 between Rignot and Radio Eco-shock on Antarctica.

A welcome two, arizona1. One of Mark's from 2013

That, of course, augurs poorly for humans. Scientists at Stanford calculated recently [ http://news.stanford.edu/news/2013/august/climate-change-speed-080113.html (and see {linked in} http://investorshub.advfn.com/boards/read_msg.aspx?message_id=90655079 and preceding {and any future following})] that human emissions are causing the climate to change many times faster than at any point since the dinosaurs died out. We are pushing the climate system so hard that, if the ice sheets do have a threshold of some kind, we stand a good chance of exceeding it.

As you know there are heaps on the board about Thwaites, one here with some

West Antarctica Glaciers: Past the Point of No Return
https://investorshub.advfn.com/boards/read_msg.aspx?message_id=102380749

and super storms, et al thanks to Mark. He knew climate change was important. It's nice that we all know more about what we may
expect now. Beats putting it down to natural disasters being attributed to a spiritual being, as so many of Trump's supporters believe.

Great to see you bring it all back. I'll link in more in the next few days.

Have read it now. The Day the Dinosaurs Died

Annals of the Former World
April 8, 2019 Issue

A young paleontologist may have discovered a record of the most significant event in the history of life on Earth.

By Douglas Preston

If, on a certain evening about sixty-­six million years ago, you had stood somewhere in North America and looked up at the sky, you would have soon made out what appeared to be a star. If you watched for an hour or two, the star would have seemed to grow in brightness, although it barely moved. That’s because it was not a star but an asteroid, and it was headed directly for Earth at about forty-five thousand miles an hour. Sixty hours later, the asteroid hit. The air in front was compressed and violently heated, and it blasted a hole through the atmosphere, generating a supersonic shock wave. The asteroid struck a shallow sea where the Yucatán peninsula is today. In that moment, the Cretaceous period ended and the Paleogene period began.
