Thanks Red Badger. Wow, I missed this one! Sorry, and sorry as well to all who could have been pinged in MARCH. Yow. Coral off Tahiti has linked the collapse of massive ice sheets 14,600 years ago to a dramatic and rapid rise in global sea-levels of around 14 metres. Previous research could not accurately date the sea-level rise but now an Aix-Marseille University-led team, including Oxford University scientists Alex Thomas and Gideon Henderson, has confirmed that the event occurred 14,650-14,310 years ago at the same time as a period of rapid climate change known as the Bølling warming. To all -- please ping me to other topics which are appropriate for the GGG list.

During the Bølling warming high latitudes of the Northern hemisphere warmed as much as 15 degrees Celsius in a few tens of decades.

Why do they use tortured terms such as " a few tens of decades"? Wouldn't "a few hundred years" suffice?

[Red Badger]

Makes it sound more imminent......and ominous....

It's very well known that sea level went up about 300' at the end on the last Ice Age.

There is no scientific evidence that it ever went up the 28,000' it would have had to in order to cover the tallest mountain.

not to worry! The One has promised to stop the seas from rising. But maybe he won’t do it if he doesn’t get re-elected.

Why do you assume the mountains we see today were always there?

And oh yes I always love the use of the word “scientific” as a shut up word. Since I started noticing its use in this manner I think of it the same way a liberal use “racism”.

I don’t. The Himalayan mountains were seafloor before India slammed into the underbelly of Asia.

But that was a long, slow grinding and ongoing collision. It didn’t happen since 4004 BC.

It is entirely possible that there was more than one major flood. At the end of the Ice Age, the sea level was at least 400 feet lower than today. The depth of the Straits of Gibralter are around 400 feet. A massive rapid rise in water level could have entered the Straits (with less depth then) and rapidly scoured it to the current depth while causing massive flooding throughout the Mediterranean basin. There could have been a second influx of water following the melting after the Younger Dryas around 11,000 years ago.

Scientist often have disagreements over interpreting physical evidence. Just saw this interesting article on disagreement over the meaning of certain formations on Mars which may support or deny the existence of substantial amounts of water in the past.
