Regional setting and ice history. (A) The Eastern Settlement of Southern Greenland. The inset shows the entirety of Greenland; dark gray depicts grounded ice cover at present, light gray is land, and white is ocean. Eight black stars show locations of the Viking sites considered herein and also Nanortalik, where Late Holocene relative sea-level data have been collected (11). B is Brattahlid, D is Dyrnaes, G is Gardar, H is Hvalsey, N is Narsaq, N2 is Nanortalik, S1 is Site 1, S2 is Site 2, and uS is Undir Solarfjollum. (B) The tetrahedral grid across Southern Greenland used in the sea-level simulation (top 72 km of Earth’s interior is shown in light gray; surface shading reflects grid resolution and is discussed in Material and Methods Section 3B) with ice mask (blue to white gradient) overlain. The ice mask is estimated from ref. 12. The yellow box shows an area encompassing the Eastern Settlement and the area of ice growth (the same area is shown in Fig. 3A). The green box shows an area with several important Viking settlements, where coastal flooding is assessed (also seen in Fig. 4A). For more details, Section 3A. (C) Time-varying growth for our ice history, normalized to a maximum value of 1.0, and adapted from refs. 13–15. DOI: 10.1073/pnas.2209615120

Damn SUVs...damn gas ovens!

Oh noes!! Global warming!!

[ClearCase_guy]

The departure of these Viking settlers coincided with the beginning of the period known as the Little Ice Age, which had a particular impact on the North Atlantic. But while cooling and freezing might seem likely to lower sea levels, a variety of factors combined to have the opposite effect in Greenland.

So, the scientific consensus is basically, "It's whatever."

Colder? That's Global Warming and rising seas.
Warmer? That's Global Warming and rising seas.
Remarkably steady? That's Global Warming and rising seas.

Climate Change, is there anything it isn’t responsible for?

[FlyingEagle]

What if there was sudden land mass subsidence in Martha’s Vineyard, and in Nantucket. Our climate Czar and Brandon Junta friends would need new luxury beach houses. Quelle dommage.

[Organic Panic]

Oh Bullcrap. These “researches” don’t have a clue why the Vikings left.

[SauronOfMordor]

We are not talking about steel skyscrapers here. We are talking about wooden huts. If they at risk of flooding the Vikings would have moved the huts further up hill.

Greenland was settled during the Medieval Warm Period, when melting glaciers made the land well watered and green, and abandoned when it got too cold to farm there.

[Maine Mariner]

Impossible. President Trump was not President.

[Freedom_Is_Not_Free]

Those darn Viking Sport Utility Ships were a cause of global warming.

[arthurus]

Sea levels have been rising for 7000 years.

[marktwain]

However, a closer look at previously published geomorphological and paleoclimate data and the researchers' modeling of ice-sheet growth suggested that the opposite occurred in Greenland,

In other words, based on a computer model.

These computer models are a classic example if garbage in, garbage out.

Models are not science. They reflect the researchers desires.

[cdcdawg]

Drumph’s fault!!!

[redfreedom]

I can imagine diesel powered ships and coal fired generating stations were responsible for the Viking abandonment. Those dang fossil fuels will make the water rise anywhere.

[jpsb]

BS, cold is what drove the vikings from Greenland. Little ice age started around 1400 and it got real cold.

[linMcHlp]

The weather, plus running out of fuel. Real estate agents hyped a place that disagreed with buyers who managed to view the property. Women. Rumors. News from home. Signs. Islamic wars required warriors back home.

[Brasky]

Sea levels had risen in Greenland but not in Europe? In 1066, William the Conqueror had to wait to cross the English channel due to unfavorable winds. I’d say they left because it was cold and no food.
But hey, I’m no expert.

[Political Junkie Too]

What the researchers found was striking: Not only were sea levels drawn up by gravity, other factors—including the subsidence of Greenland's land mass—made the settlement more prone to flooding.

In other words, the Viking settlements were causing Greenland to start tipping over, so they left?

If true, Greenland ought to be underwater by now................

The old adage “All computer models are wrong, though some are useful”, has been my guiding light in a 60-year career using computer models. This one makes me highly suspect. For starters, the verbiage says 3 meters of sea level rise, while the chart indicates one and a half meters. They also show the sea level ‘rise’ to be at the start of the Little Ice Age, rather than at the end. How could the so-called gravity effect of the accumulating ice start before the ice actually accumulated?

Color me highly skeptical. This one seems to me to be not one of the not ‘useful’ models.
