Arctic sea ice at record low for this time of year

[FrumiousBandersnatch]

6m (20 ft) is Greenland alone. By itself that would be catastrophic but if the Antarctic goes too that's 60m (200 ft) and that would be well beyond catastrophic.

We'd all need our wellies...

It was called Greenland for a reason.
What happens after a ice age?

Australia being relatively close to Antarctica is well prepared for the up coming crisis.

Lief Erikson called it Greenland as a ploy to recruit settlers to establish a new colony. At that time only a tiny portion of Greenland on the south west coast was in any way green. It is actually much greener today. They are now able to grow hay and hardy crops like potatoes, carrots and turnips but they are not yet self sufficient in food.

Nooo. It was called Greenland due to its tropical rainforest!

And the Romans grew grapes in Britannia, what does that tell ya.

The more the ice melts and uncovers the ground of Greenland the more remains of settlements are discovered, what does that tell ya?

It tells me that Cornwall being warmed by the Gulf Stream has a warm enough climate to support viniculture.

The archaeologists will be excited. BTW did you know that several locations in Canada produce internationally award winning wines?

GMO grapes? Or are we back to where we were 1,000 years ago?
So you think the end of the great ice age was caused by CO2?

 

[JackRT]

Actually we are quite a bit wamer than at that time.

I am a nuclear physicist so I cannot give you an authorative answer. There are a number of possibilities including CO2.

So do the ice core samples offer us any clues?

 

[JackRT]

I really don't know.

 

[johneb]

I really don't know.

Ice core samples from Vostock to the Arctic concur that CO2 levels follow warming periods by 400 years, this data suggests the rise of the CO2 level is a result of warming and not a cause.
So why would any credible scientist believe CO2 is causing warming now? Perhaps because they are paid to prove it, governments fund grants and hungry scientist are eager to take the money.

If CO₂ is a result of warming both the troposphere and lower stratosphere temperatures would be increasing.
Instead the lower stratosphere temperature is decreasing which is a signature of AGW.
An explanation for this is given here.

I wish you guys would get your stories straight. If you listen to the WUWT crowd, CO2 both preceeds warming by 800 years, and it lags waming by 400 years. Or is that 800 years?

Could you tell me which it is?

Of course, I could just listen to the scientists that study this who demonstrated the complex interplay between temperature and CO2, Milankovitch cycles, solar output, biosphere CO2 absorption and the difference between the pre-industrial period and the post industrial period.

But, what would they know?

How about 600 years? would you buy that? If I gave a rock to a geologist and asked "how old is this rock" he may answer it's less than 50 million years old and he would be correct.
If God made a rock yesterday, How old is that rock? It's as old as God made it to appear to be. "As high as the Heavens are above the Earth are my ways higher than yours says the Lord"
I don't see the advantage of details, I do see a advantage of faith and a relationship with God.

They were growing vines as far north as Lincolnshire.

 

[Gene2memE]

600 years what? Lagging? Preceding?

would you buy that?

My level of confidence would correlate with the level of evidence you provided. I'd give my highest degree of confidence into independent work of experts that has been adversarially verified by contemporaries.

Thank you for that non answer.

I don't see the advantage of faith, nor do I believe in relationships with conceptual beings I am unable to determine the existence of. Nor do I accept any variant of 'apparent age' via supernatural causation (nor would have I when I was a practicing Catholic).

I'll stick to well supported natural explanations that are continually tested and verified by experts in the field.

NASA link. Extent and area are minimum or tie the minimum measured on July 8.

Although 2020 didn't go lower than the absolute minimum set in 2012, the ice has been slower to reform, so that it is currently at a record low.

The effect seems strongest in Siberia.

Arctic ice is seasonal. It melts down in the summer sun and relative warmth, then freezes back up when fall’s chill comes. Or at least, it should be that way. But right now it’s late October, and the ice in Siberia’s Laptav Sea still hasn’t refrozen. It’s the latest ice-free date the sea has seen in recorded history and is driving Arctic sea ice as a whole to its lowest point on record for this time of year.
