“when temperatures than they are today”
Scientists say current concerns over a tipping point in the disappearance of Arctic sea ice may be misplaced.
Danish researchers analysed ancient pieces of driftwood in north Greenland which they say is an accurate way to measure the extent of ancient ice loss.
Writing in the journal Science, the team found evidence that sea ice levels were about 50% lower 5,000 years ago when temperatures than they are today.
They say changes to wind systems can slow down the rate of melting.
They argue, therefore, that a tipping point under current scenarios is unlikely.
While modern observations by ship and by satellite give us a very accurate picture of the recent state of the ice, historic information is limited. The ice comes and goes without leaving a permanent record.
But a Danish team believes it has found an indirect method that gives a clear picture of the ice loss dating back 11,000 years.
Dr Svend Funder from the Natural History Museum of Denmark led several expeditions to inhospitable regions of Northern Greenland. On these frozen shores the Danish team noticed several pieces of ancient driftwood. They concluded that it could be an important method of unlocking the secrets of the ancient ice.

It is no accident that the words “were higher” are missing. They were removed because they don’t fit the alarmist narrative.
Indeed. That whole paragraph has now been edited to
“Writing in the journal Science, the team found evidence that ice levels were about 50% lower 5,000 years ago.”
I read about this type of research years ago!

I’m not sure about that 50% sea-level. Does that have any meaning (outside of a model with a uniformly flat-bottomed ocean)?
Ah, it’s sea-ice levels – a different thing. Sorry.
Greenland is a block of ice. They only named it Greenland to fool people into moving there instead of Iceland, which really IS green. Julienne says so:

If a person wants respect they should at least not make stupid claims such as this! Real scientific research shows that claim to be a lie! A real scientist would know the history of the region they were studying!
Grumpy,
good to know you can still be outraged even though you think scientists are lying all the time anyway!
Well that is certainly not settled science. Even Wikipedia has it in conflict …
I think she is jumping the gun on this by spreading the myth version exclusively. Particularly since the vikings got there in warmer times (Wikipedia again) …
“They say changes to wind systems can slow down the rate of melting.”
Whoda thunk it. They’re fricking geniuses.
