Solar may not be determinative in a particular case. It might affect totals.

Unexpected Ice
Quote:
According to climate models, rising global temperatures should cause sea ice in both regions to shrink. But observations show that ice extent in the Arctic has shrunk faster than models predicted, and in the Antarctic it has been growing slightly.
TLDR; rate of increase more important than extent. Effects in Autumn precipitated by winds in Spring.

A lack of solar activity allows the the polar jet to wander around drunkenly.
Then in about 5 years during solar maximum and the jet stream generally stays where it's supposed to and much of the country will be summer like into October or November if we're lucky and that lack of of snow and warm weather will be "proof of global warming".

'Extent' is a weasel-word.Its use is considered improper by glacialologists.What is of concern to climatologists is ice 'volume,' not extent.And it is ice 'volume' that is in decline,regardless of 'extent' which could be paper-thin,and of no consequence.
Also,albedo is of great concern.Long ago and far away we had powder snow covering the ice,which had the best surface-reflective index known.We don't have that like in the past.Ice is much darker than snow,and it leads to accelerated melting.Melt-water is worse than ice.And open ocean water even worse,except for exposed land.
Any accumulation inland must be balanced by loss at lower,warmer elevations along the continental perimeter and sea ice.Also,foehn winds are blowing snow off Antarctica before it has any chance to accumulate.
Ice is being lost from below.It's like Swiss Cheese.There are unexposed fissures/crevasses just below the surface.Water temps below the ice are above freezing.Ice shelves are losing icebergs as large as states.

If this is true then why didn't we get a bunch of volcanic eruptions when the mile thick slab of ice melted over north America?

This is easy to understand: our climate crisis is doing BOTH - more evaporation leads to more drought is some places and times, AND leads to more precipitation in other places and times.

The alien/asteriodal impactor that took out the Clovis people.

We got the Eastern Washington state scab-lands instead.

I found out this morning that the Olympic peninsula was once an island named Siletzia on the Pacific plate that was skimmed off like a scab by a razor as the plate subducted. What made the island? The mantle hot-spot that is now under Yellowtone.

About 3,000 to 4,000 year ago there was a devastating drought in the middle east. That was a climate change drought as it lasted at least hundreds of years.
A little drought or flood isn't proof of climate change, man made or not.

I can't tell if you're being serious or not? The Scablands were created by the breaking of the ice dam holding back Lake Missoula.
