Blah blah blah blah blah blah blah blah blah......There is no point since you know you cannot refute one word.
Parroting CO2 FRAUD BS as a "faux skeptic" again, you've been completely refuted already...
durr..
CO2 FRAUD is 100% about getting science invalids to believe planet Earth warms and cools as a whole. That conclusion was completely blown out of the water by the fact that Greenland froze while North America thawed during the past 1 million years.
The "interglacial" is part of CO2 FRAUD's attempt to mislead on that issue.
The last interglacial...

You refuted that the most recent glacial maximum ended 21,000 years ago?
LOL!
Funny you bring that up. The vikings were farming on the southern tip of Greenland until 1400, meaning 21000 years ago there was no ice at all on the southern tip, supposedly a "maximum."
That's the 7% data point, it has gotten LARGER and the ICE CORES prove it grew a new ice layer EVERY YEAR including 21000 years ago...
The 90% from Antarctica has also grown 21,000 new ice layers since 21,000 years ago, meaning the "maximum" is COMPLETELY REFUTED by 97% of Earth ice, nice....
for North America was 50 million years ago according to North American Ice Age.
There was less ice on Antarctica and Greenland than today, and the ice cores prove it.
21,000 years ago, ice sheets covered large parts of Illinois.
Now there are no ice sheets in Illinois.
What was the magic movement of NA that melted all that ice.
The main question is when did the ice that was between Ellesmere and continental Canada melt and why.
Answer is speculative.
We have seen large volcanic heat releases from under Arctic Ocean. That's clearly a big suspect.
How long does 5 million cubic miles of ice take to melt once outside of 600 miles to an Earth pole - speculative, likely in the 3 million year range.
How far is Ellesmere from the pole now?
How far was it 21,000 years ago?
How far was it 100,000 years ago?
within 600 miles, hence still in ice age with 30k cubic miles of ice on it

Deeply Submerged Volcanoes Blow Their Tops
A research team led by Woods Hole Oceanographic Institution (WHOI) has uncovered evidence of explosive volcanic eruptions on the Arctic Ocean seafloor almost 2.5 miles deep. Scientists did not think volcanoes submerged under such intense water pressure were capable of such violent eruptions...www.whoi.edu

Why did ice cover huge parts of NA 100,000 years and not today?
Read the OP, that is completely answered there. Right now, there is ice age glacier on Ellesmere and nowhere else, because Ellesmere is the only part of Canada still within 600 miles of the pole.
Laurentide likely took around 3 million years to melt after growing for over 40 million into 5+ million cubic miles of ice. The past 100k years saw the end of the ice melt from Indy to Northern Canada. Nowhere was it still 2.5 miles thick 100k years ago.
If Canada had no water between Ellesmere and the continent, it would still be in ice age.
When and why did that ice turn to water?
Already answered to the best of our ability to guess....
When we still had ice sheets across Illinois.
Canada had no water between Ellesmere and the continent 100,000 years ago.
No, you had pieces of ice that moved. You have SCRATCHES dating from that point. They aren't the 2.5 mile thick ice scratches either.
Not what was said. More likely 3 million years ago, and when that ice turned to water, then the 3 million years of (net) melting started, how long it takes 5 million cubic miles of ice, 2.5 miles thick, to melt.
That only happens when ice sheets expand.
False.
When big ice sheets melt for hundreds of thousands of years, they develop rivers and drainage pathways. In Indiana, the most likely explanation is that a piece of ice roughly one mile thick broke lose and scratched the ground when it did. That does not mean Indiana was covered under mile thick ice 10k years ago, no. Rather, the higher elevations melt first, dump water on the lower elevations etc.
There is a summer winter contraction/expansion on the melt line every year, is on Greenland now. But year over year Greenland's ice is not retreating, just the opposite.
The entire attempt to cover up North American Ice Age and hence prevent the truth that
Greenland froze while North America thawed at the same time
is actually all based on rock scratches, that's the only actual evidence McBullshit claims it has, claims of rock scratches from people who fudge data, seed clouds, and squirt chemical bleach into coral....
