Antarctica has grown ice for more than 2.7 million years, disproving "interglacials" completely

You show a chart of oxygen isotopes from one ice core in AA that doesn't show ANY "abrupt climate change."

Why haven't you eaten that bullet yet?

 

[Anomalism]

No, I'm not conflating trigger and driver. You are refusing to accept the ocean is responsible for abrupt climate changes. You believe orbital forcing is... which I believe is dumb.

Climate variability isn't well understood. Clearly the system is capable of warming another 2C all on it's own. Just because they can't understand it doesn't mean they should ignore the empirical climate evidence of the geologic record. Rather they should be seeking to understand it so that they can then model anthropogenic changes more accurately.

The oceans absolutely drive regional and even abrupt climate shifts, but they don’t create or destroy net energy; they redistribute it. Orbital forcing is small in magnitude compared with today’s radiative imbalance, and it sets the slow, multi millennial pace of glacial cycles, not the warming we see now.

The geological record informs sensitivity and feedbacks, but it doesn’t explain the 20th-21st century trend. That spike is superimposed on natural variability and disappears if you remove anthropogenic CO2.

Earth not warming, no "spike" except if it is FUDGED.

Sincerely,

highly correlated satellite and balloon data showing NO WARMING in ATMOSPHERE
Surface Air Pressure
Hurricane data proving no warming in oceans
The inability of CO2 FRAUD to show us any ocean "rise"...
which proves NO ONGOING NET ICE MELT

So ice core samples might only go back a few hundred years instead of a few hundred thousand years

I can't confirm where on Greenland that is, but if it is on the southern tip, it makes sense. That ice is really only 600 years old there, but it came "through" a mountain range at the top of southern tip to get there, released compression force built up against the mountains for hundreds of thousands of years, almost a mile thick. All of the Viking homes on the mainland are buried under that ice too. The top of ice age glacier, when it just starts, isn't that high off the ground, and hence gets the full annual snowfall. The lower layers aren't yet compressed. When it gets higher in the altitude, it gets less snow as a result.

AA has 900k years of data not even a mile down, just how "thick" the layers are once you compress them with thousands of years on top.

"A team has located a World War II P-38 Lightning fighter plane beneath more than 300 feet of ice in Greenland."


Greenland likely has years where it gets 20+ feet of snow, being surrounded by water. No different than Buffalo or Vermont. Buffalo averages 8 feet.

We're also talking about a crash of an airplane.

What angle did it hit? Did it penetrate the top layers of snow/ice? Did the warmth of the engine melt surrounding snow/ice and push the plane down as a result of the crash?
