Is Anthropogenic (Human-Caused) Global Warming/AGW Falsifiable?

[EMH]

has been slowly cooling for the last 6,000 years

Because the North American Ice Age was fully melted by 6k years ago, while the Greenland and Antarctic ice ages have grown, and continue to do so, which is why there is no ocean rise and a downward trend in Surface Air Pressure.

 

[Grumblenuts]

Antarctica is losing ice mass (melting) at an average rate of about 150 billion tons per year, and Greenland is losing about 270 billion tons per year, adding to sea level rise.

We see in SunsetTommy's Signature two ideas/'truths' meant to show it isn't falsifiable and is therefore Not a Valid theory/truism.

“A theory that is not refutable by any conceivable event is non-scientific.” – Karl Popper​

​

"The climate system is a coupled non linear chaotic system, and therefore the long-term prediction of future climate states is not possible" --- IPCC​

But Of course, it is Falsifiable, and the two statements above do Not necessitate any conclusion.
Saying so is a non sequitur.

If ie, we hugely cut our emissions as a planet, and GHGs returned to what they were before man drove them up: (ie, CO2 50%/280-420; or Methane 3x,) and the warming didN'T gradually stop and even reverse, that would discredit the theory, BARRING other factors as the many Solar Cycles (Milankovich etc).

Because no one is claiming that it can't get cooler IF Weakening of Solar Forcing (earth tilt changed, or distance increased cyclically) (or a La Nina, etc) overrode it due to any event - foreseen or unforeseen - just that Man IS causing it to warm with these Aptly name Greenhouse gases. And if a weakening of the sun cooled it, it would still be warmer than it would otherwise have been due to our thicker GHG blanket.

In fact, the theory continues to be Validated (which is how science works). Theories, like Evo, Atomic, etc do not get Proven. (A 'God' could always pop up and say he is the cause of anything.)
Scientists have already tested this by directly measuring Solar energy hitting earth, and shown that is has NOT Changed in 50+ years... UNLIKE what has caused ALL the other warming/cooling cycles.

They have also measure solar energy being Reflected back out into space, and it is being Blocked/Trapped at the exact spectral wavelengths of - again - (the aptly named) Greenhouse Gases.

That/those two is one of the biggest reason we know.

This falsifies AGW.

If "the ice is melting"

CAN YOU SHOW US A PHOTO OF OCEAN "RISE?"

AND IF YOUR ANSWER IS NO, WHY NOT???

AND THEN EXPLAIN WHY SURFACE AIR PRESSURE IS DECLINING....

 

[Dagosa]

Sorry, but that's incorrect. The Earth's glacial-integlacial cycle peaked at the Holocene Climate Optimum and has been slowly cooling for the last 6,000 years. Look at the temperature reconstructions of the Holocene.

Of course you don’t have a reference.

How is the current global warming trend different from previous warming periods in Earth's history?

Today's global warming is happening at a much faster rate today than it did in the warm periods between ice ages over the last million years.

The Earth is not warming, and the Co2 FRAUD is completely wrong with its "definition" of "ice age"

Apparently we really need a "debate" over the term ICE AGE because y'all are all wrong...

What is an ICE AGE? Most apparently still believe it is a terrifying horror movie event where Earth all at once freezes up. The data has never supported such a scenario. Since 2010, there has been a massive effort to re-write Earth climate history into a series of rapid "glaciations" and ice...

Classic Dag.

"Ocean rise" = storm surge...

LOL!!!!

There was "OCEAN RISE" (really a Cat 5 storm surge) on Martha's Vineyard in 1938 which put homO and Big Mike's house underwater (had it been built at the time). Why is that house not underwater now?


As for Antarctic Circle vs Arctic circle

Antarctica 90%
Greenland 7%
Ellesmere Island 0.3%

So according to Dag, land near the poles has nothing to do with it, it is rather...


"it’s fking snow ice which accumulates nine times faster than sea ice idiot"


LOL!!!

Nit wit…you keep “pretending “ you’re ignorant and don’t know the difference between snow/ glacial ice and sea ice. You’re cluttering up the board with your ridiculous drivel.

Obviously you’re a fraud. You throw out numbers with no reference….none. Then you pretend that a previous post means something……shit for brains.

How global warming is unlike the last 2,000 years of climate shifts | Science News

Temperatures at the end of the 20th century were hotter almost everywhere on the planet than in the previous two millennia.

www.sciencenews.org

Those are all normal fluctuations represented as periodic functions and indeed, the small increases just before the industrial revolution is an upward trend. That it’s happening at a faster rate is what is more important., Your models are all periodic functions in an overall increase and there is no proof it would have continued down if the industrial revolution had not occurred. That the rate of increase far exceeds any increases in fluctuations makes your observation mute.
The key point negating your observations is this statement.
……”Such nearly universal warming, occurring in lockstep across the planet, is unique to this current era, scientists say. By contrast, other well-known cold and warm snaps of the past, such as the Little Ice Age or the Medieval Warm Period, were, in fact, regional rather than worldwide.”
AND…
“What’s more, the rate at which temperatures are increasing now far exceeds any previous temperature fluctuations measured in the last two millennia. “

The entire atmosphere of GHG's only trapping 44% of their theoretical surface temperature because convective currents whisks heat away from the surface falsifies AGW.

That's not how science works. You don't just make up some crazy stories and declare you win. You've been failing at the basics here for ten years now.

We've pointed out many times that many things can falsify global warming, since it's real science. I've posted a list multiple times.

In contrast, I've asked deniers many times what hard data would falsify their theory. They never answer. That's because deniers don't have a theory, they have a religion, and a religion can't be falsified.

Laughable.

Take atmospheric temps.

Your THEORY is that adding Co2 to the atmosphere would warm the atmosphere. We have two and only two measures of atmospheric temps, satellites and balloons...

THE DATA =

Key claim against global warming evaporates

Satellite and weather balloon data used to argue that climate models were wrong and that global warming isn't really happening turns out to be based on faulty analyses, according to three new studies.

www.nbcnews.com

satellite and weather balloon data have actually suggested the opposite, that the atmosphere was cooling

So while there was a "cold snap" on Greenland, at the same time there was a "warm snap" on North America???

Such is the idiotic BULLSHIT of the Co2 FRAUd.

Do you have laboratory measurements of emissivity through the various media we're discussing? ... do you have the calculated values we can compare to? ...
