Here is what you are attempting to do. You say, correctly, that correlation is not causation. GOOD! That's why scientists use a lot more inputs than just CO2 in their models. You neglect this truth and fixate on any trend in a number of years to say, AHA!, looky here, the CO2 is going up and the temperature is going down! At this point you flip the "correlation is not causation" logic on its head and say LACK of CORRELATION proves CO2 doesn't have beans to do with global temperatures!
Ya CAN'T HAVE IT BOTH WAYS, Snowleapard. Which is it going to be? The correct scientifically objective answer is to look at other GHG correlation, the granularity of the graph and the time scale. Mathematical models are used to design engines, aircraft, consumer goods, cars, houses, time and motion studies, integrated circuits, computers and many other technologically demanding and high number crunching applications.
Yet you want to disparage the accuracy of incredibly complex mathematical climate models (spreading DOUBT about NOT KNOWING in order to justify DOING NOTHING is DISPARAGING the science, whether you will ever admit it or not) based on the belief that some negative feedback mechanisms were left out.
Well, I've got news for you, Guy McPherson, a scientist in his own right, has listed FIVE POSITIVE FEEDBACK MECHANISMS that ARE NOT in the models. That means the IPCC global temperature increases projected in the models are STILL TOO CONSERVATIVE.QuoteThe Arctic is defrosting as warm Atlantic waters rush through the Fram Strait instead of skirting the southern coast of Greenland. This is an important event, regardless of the deafening silence exhibited by the mainstream media.
How important? First consider the background, from the perspective of long-time climate scientist James Hansen and colleague Makiko Sato, who report the disaster awaiting us at just a couple of degrees warmer is truly catastrophic (although they downplay the likelihood we’re already committed to this outcome.)
Suffocating lifestyle
At the same time Arctic ice is melting, the planet is losing its lungs. Catastrophic drought in the Amazon has it emitting carbon dioxide more rapidly than the United States.
Simultaneously, permafrost is thawing and methane stored in eastern Siberia is venting into the atmosphere at an alarming rate.
Methane, by the way, is a much more powerful greenhouse gas than carbon dioxide.
Against this background, it’s easy to foresee a rapidly and profoundly warming Arctic as a trigger for accelerated responses such as the release of more methane hydrates and fewer reflective white surfaces, such as ice sheets and areas covered with snow.
These extremely dangerous feedbacks, which forecasters did not expect until the planet becomes a couple of degrees warmer than the baseline, could trigger runaway greenhouse. In other words, any of these events — never mind all of them at once — could lead directly and quickly to the extinction of you, me and everyone in between.
Is that important enough for you? Or do you still want to debate it with the likes of these guys?

And 1 C is catastrophic, as indicated by a decades-old cover-up. Already, we’ve triggered several positive feedbacks, none of which were expected to occur by mainstream scientists until we reached 2 C above baseline global average temperature.
We also know that the situation is far worse than indicated by recent data and models (which are reviewed in the following paragraphs). We’ve known for more than a decade what happens when the planes stop flying: Because particulates were removed when airplanes were grounded, Earth warmed by more than 1 C in the three days following 11 September 2001.
In other words, Earth’s temperature is already about 2 C higher than the industrial-revolution baseline. And because of positive feedbacks, 2 C leads directly and rapidly to 6 C, acidification-induced death of the world’s oceans, and the near-term demise of Homo sapiens.
We can’t live without life-filled oceans, home to the tiny organisms that generate half the planet’s oxygen while comprising the base of the global food chain (contrary to the common belief that Wal-Mart forms the base of the food chain). So much for the wisdom of the self-proclaimed wise ape.
With completion of the on-going demise of the industrial economy, we’re there:
We’ve crossed the horrifically dire 2 C rubicon, as will be obvious when most of the world’s planes are grounded. Without completion of the on-going demise of the industrial economy, we’re there: We’ve crossed the horrifically dire 2 C rubicon, as described below. Joseph Heller, anybody?
I’ve detailed the increasingly dire assessments. And I’ve explained how we’ve pulled the trigger on five positive-feedback events at lower global average temperature than expected, while also pointing out that any one of these five phenomena likely leads to near-term human extinction. None of these positive-feedback events were expected by scientists until we exceed 2 C warming above the pre-industrial baseline.

The above charts tell the story that you simply do not want to deal with. They are EMPIRICAL OBSERVATIONS, not mathematical model predictions, even though ALL those readings and many more have been incorporated in the multiple terabyte size data bases of the climate models (that continue to grow in complexity and prediction accuracy because of this).
Fine. Do your thing.

The ANOMALY is not the temperature reading.
I didn't say it was. It is the amount of departure from the 100 year average.
Quote

NOT TRUE: It can flatten anywhere. And if it stays there long enough the anomaly will eventually be zero by definition.

NOT TRUE: If it can't decrease before going negative, then (other than massive decline) it would be unlikely to get from it's current moving average of 0.6C to ZERO, if it can't decline before it gets there!

I can't have it both ways...but you can...HUH?? YES i know it is complicated, that's not the point. I've been focused on two things here. ONE that warming has stalled, (which BTW is generally accepted) and TWO that CO2 is unlikely to be a major cause of the mild warming before that. (which is not yet generally accepted, but true).

Both MKing and Snowleapard have it exactly backwards by claiming the models exaggerate the risk and the predicted temperature rise. But they have that CIGAR they want to smoke and think I am a killjoy for wanting to take away their fun, regardless of their protestations to the contrary or claims of boundless, 'let the chips fall where they may', slavish devotion to truth, objective scientific data, Apple pie and Wildebeest hunting.
