I was born in SE England in 1941. I'd be grateful if you could tell me more about the 'drowned villages' there specifically caused by climate change since the ice age? Thanks. I think maybe coastal erosion is more the issue there.... Not to the extent that could have caused villages to drown.

The opposite is the case no flooded villages - go to Pevensey Castle (somewhere I spent a lot of time at many years ago). The castle used to be on the shore in Roman and Norman times but is now more than a mile away from the sea. ( Sea level higher in Norman Times) So Isostatic rebound, sinking the South and raising the North, has not caught up with the sea level _drop_

The point you were making, not very clearly [!], is that Pevensey Castle is in the South of England not far from where I used to live.
That area is very slowly sinking, and if anything the sea should have been absorbing the castle, and not a mile away.
Who said "Observation trumps theory every time"? .

Credit: National Snow and Ice Data Center High-resolution image Arctic sea ice extent for February averaged 14.22 million square kilometers (5.48 million square miles), the lowest February extent in the satellite record. It is 1.16 million square kilometers (448,000 square miles) below the 1981 to 2010 long-term average of 15.4 million square kilometers (5.94 million square miles) and is 200,000 square kilometers (77,000 square miles) below the previous record low for the month recorded in 2005. So....92.2% of the 15%+ sea ice is STILL there....During a 'monster' El nino winter too. Economists don't really panic unless there's a 20% drop in shares over 2 months. Also, is it just me or is it that as the Pacific ssta wane, the arctic and Antarctic ice extents seemingly stop losing so much?? nsidc.org/arcticseaicenews/

You should patent that level of sophistication Doug.

Meanwhile, back in the Arctic, IJIS has seen 7 days of loses as we crest the hill and face the slope that is melt season. Currently second lowest in extent ( 2006 lower) with both volume and Area at the lower end of their ranges. If we see early warmth across Beaufort I'd expect a very patchy look to the pack very quickly as low volume ice cover much of the Area? We can only hope that this years crackopalypse has allowed infill ice to strengthen , and not weaken, the pack?

Graywolf, the Antarctic has much more ice, and as indicated with sophisticated methodology is growing in extent unusually quickly. weather.unisys.com/surface/sst_anom.gifI would suggest that the cold water SST anomaly surrounding the Antarctic has some claim to being by far the largest geophysical anomaly on earth. I don't know what it means in the medium term, but I doubt the word "warming" will feature to any great extent. There appears to be quite a lot of evidence that with a 20 year lag, temperatures on earth are substantially controlled by the level of solar output. Currently moving from the greatest extent in the last 8,000 years to the weakest.

www.cbsnews.com/news/nasa-says-arctic-sea-ice-near-record-low/The ice covering the Arctic is at near record lows this year, and this icy deficit may impact weather around the world, NASA reports. Every March, the Arctic's sea ice reaches its maximum cover, both in area and thickness, before it recedes to its yearly minimum in September. Live Science spoke with NASA scientist Walt Meier to learn more about the low sea-ice level and what it means for the rest of the planet. This winter has been extremely warm, Meier said. "Temperatures have been 10 to 15 degrees Fahrenheit [5.5 to 8.3 degrees Celsius] above normal [in the Arctic]. And we see that reflected in the very low sea-ice cover that generally grows to its maxima [maximum] around this time of year.

I thought the answer to the unusually warm Arctic was that it was an EL Nino year.
When I looked at the COI graphs for 1997, 1998, 1999, my hypothesis was invalidated.
I could not post the graphs because apparently this forum has reached its upload limit.
WHY was the Arctic so warm this winter?

Fluctuations still seem due to weather this winter....
