Laughable. Your "global mean temperature" for 90% of the past million years is ONE ICE CORE FROM AA.
because SAP is PLANETARY. The T in the equation is the GLOBAL MEAN TEMPERATURE. There is no better way to get GLOBAL MEAN TEMPERATURE...
because both or either would push SAP higher, and do on Mars.
Your side has ZERO to refute that.
No. The EVIDENCE is as follows.
1. all forms of air pressure are correlated with temperature, a planet's surface air pressure is no different
2. the clear truth from Mars, that as Mars GLOBAL MEAN TEMPERATURE rises, Mars SAP rises with shockingly high correlation
3. the clear truth that Earth, which has a much more circular orbit but is slightly elliptical, has a 1-2% "bump up" of SAP when CLOSEST TO SUN in January
4. that Earth SAP has been defined as a "standard" down to FIVE DIGITS for decades if not centuries
5. that for the past 60+ years Earth SAP is flat to down
all of that proves...
1. no additional mass is being added to atmosphere, proving NO ONGOING NET ICE MELT, which would add mass to atmosphere
2. no warming
What do you have?
ZZZZZZzzzzz...
Let's go through your five points one at a time, because this is where your argument actually collapses.
Point 1--"All forms of air pressure correlate with temperature." Locally, yes. That's weather. A warm air mass expands and creates low pressure. A cold air mass contracts and creates high pressure. This is why meteorologists use barometric pressure to forecast storms. But you're making a
planetary claim--that global mean SAP functions as a reliable proxy for global mean temperature over decadal timescales. That requires a completely different physical mechanism, and you haven't identified one. Correlation in weather systems does not establish SAP as a century-scale global thermometer.
Point 2--Mars. Mars is doing a lot of work in your argument and it can't carry the load. Mars has no oceans, no hydrological cycle, no biosphere, and an atmosphere composed almost entirely of CO₂ at about 1% of Earth's atmospheric density. Its SAP variations are driven primarily by CO₂ sublimation and deposition at the poles--the atmosphere literally freezes and thaws seasonally. You're asking a Mars analogy to transfer to a planet with dynamic oceans, complex land-sea pressure gradients, a water vapor feedback system, and an atmosphere 100 times denser. That's not a parallel. That's a completely different physical system.
Point 3--Earth's January SAP bump. You're describing a well-understood orbital mechanics effect--Earth is slightly closer to the Sun in January, receives marginally more solar radiation, and SAP ticks up fractionally. This actually
hurts your argument. It demonstrates that SAP responds to solar forcing on short timescales. Decades of greenhouse forcing should show a signal too--unless you're prepared to explain why one forcing registers and the other doesn't. You haven't done that.
Point 4--That formula you posted--the barometric equation. T appears in the denominator governing how pressure varies with altitude. A warming atmosphere expands vertically and redistributes pressure upward. Surface pressure can stay flat or decline even as the atmosphere warms. You handed me a formula that is
compatible with AGW and called it a refutation. It isn't. It's confirmation that your own cited physics doesn't support your conclusion. Precise measurement of a stable quantity does not make that quantity a global temperature proxy. A ruler measures length with extraordinary precision. That doesn't mean stable ruler readings tell you the temperature of the room.
Point 5--Earth SAP flat to down for 60+ years. This is your core claim and here's where it breaks entirely. You're asserting that flat SAP proves no atmospheric mass increase--therefore no net ice melt. But you've already conceded the mechanism yourself without realizing it: ice melt adds water to the
ocean, not mass to the
atmosphere. Sea ice melt is volume displacement--it was already floating. Land ice melt runs into the ocean. Neither pathway adds meaningful mass to the atmosphere. Flat SAP is therefore
completely compatible with ongoing land ice melt and sea level rise. Your own logic refutes your own conclusion.
And here's what you
still haven't touched: satellite tropospheric temperature measurements, ocean heat content to 2,000 meter depth, three decades of radar altimetry showing sea level rise, GRACE gravitational satellites directly measuring ice mass loss, and radiative forcing measurements confirming CO₂'s heat-trapping mechanism in the actual atmosphere. Eight independent measurement streams from competing institutions in different countries with different funding and different methodologies--all pointing the same direction.
You called my global mean temperature record laughable because it relies on ice cores. But your global mean temperature record is
one metric--SAP--interpreted through a Mars analogy, a January orbital blip, and a barometric equation that actively undermines your conclusion. That's your evidentiary foundation.
Where is the peer-reviewed paper establishing SAP as a reliable decadal global temperature proxy on a planet with oceans?
Still waiting.
