Too funny. Roy Spencer invented satellite temperature analysis, gets called “a blogger”

Careful Cheryl Jones, your groupthink is showing. She’s a science writer who writes today in The Australian about “climate bets”, but without seemingly using The Internet.

Here’s how she describes Roy Spencer:

Although a blogger, Spencer does publish research in the scientific journals. He was not surprised that Newman had invoked his name. “I’ve testified in the United States Congress probably half a dozen times,” he tells The Australian. “My name is out there.”

To put this in perspective, this is Roy Spencer, Principal Research Scientist at the University of Alabama in Huntsville. He’s not just a climate scientist either.  Roy Spencer and John Christy were the first two scientists to develop a method for getting temperatures from satellites, and the pair won NASA’s Medal for Exceptional Scientific Achievement, and the American Meteorological Society’s “Special Award.” But Roy does write an excellent blog…

No sure bets in the climate debate

Cheryl Jones, The Australian

LAST summer, Nobel laureate Brian Schmidt challenged Tony Abbott’s chief business adviser Maurice Newman to bet $10,000 that the Earth’s average surface temperature would be lower in 20 years than now.

If Cheryl Jones had gone so far as to type “climate bets” into a [...]

Even with the best models, warmest decades, most CO2: Models are proven failures

This beautiful graph was posted at Roy Spencer’s and WattsUp, and no skeptic should miss it. I’m not sure if everyone appreciates just how piquant, complete and utter the failure is here. There are no excuses left. This is as good as it gets for climate modelers in 2013.

John Christy used the best and latest models, he used all the models available, he has graphed the period of the fastest warming and during the times humans have emitted the most CO2. This is also the best data we have. If ever any model was to show the smallest skill, this would be it. None do.

Scores of models, millions of data-points, more CO2 emitted than ever before, and the models crash and burn. | Graph: John Christy. Data: KMNI.

Don’t underestimate the importance of the blue-green circles and squares that mark the “observations”. These are millions of radiosondes, and two independent satellite records. They agree. There is no wiggle room, no overlap.

Any sane modeler can only ask: “But how can the climate modelers pretend their models are working?” Afterall, predicting the known past with a model is not-too-hard; the modeler tweaks the assumptions, fiddles with the fudge [...]

The incredible power of clouds (and Roy Spencer’s work)

Joint Post by Tony Cox and Jo Nova Clouds cool the planet as it warms

Clouds cover an enormous 65% of the planet and are responsible for about half of the sunlight that is reflected back out to space.[i]  The effects of clouds are so strong that most of the differences between IPCC-favoured-models comes from the assumptions the models make about clouds. Cloud feedbacks are the “largest source of uncertainty”.[ii] Numerous studies show models project wildly different results for clouds, and yet few could correctly simulate clouds as recorded by satellites.[iii] One researcher described our understanding of cloud parameters as being “still in a fairly primitive state.” [iv]

Sunlight that travels 150 million kilometers can be blocked a mere 1km away from the Earth’s surface and reflected back to space.  The situation is complicated though, because clouds also slow the outgoing radiation — which has a warming effect. In general lower clouds are thicker and have a large cooling effect, while higher clouds are thinner and tend to trap more heat than they reflect (i.e. net warming).  Observations show the cooling effect of clouds dominates the warming effect. (Allen 2011[v]) which means that, in general, more clouds means more cooling.

How to go out with a bang — score points for censorship — a poseur for honor!

An editor has resigned after committing the dastardliest of crimes: He helped publish a skeptical paper in a peer-reviewed journal. God-forbid, imagine a paper being reviewed only by people who have some sympathies with your results? It’s unthinkable. We all know that Nature and Science, for example, dutifully send all the papers by alarmists to at least one skeptical reviewer, and since 97% of 77 climate scientists are alarmists, that means the other two scientists who aren’t, are very busy people.  (75 of 77 climate scientists “agree” that the world is going to hell because of CO2). And who knows where they found that third skeptic?

Naturally, lots of journal editors have resigned when they’ve realized that, accidentally, they’ve only sent alarmist papers to alarmist reviewers.

As if we needed reminding about how bizarre, unbalanced, and unscientific is the creed of climate. Normally, if egregious mistakes are found, a paper would be retracted. If “normal” mistakes are found, those who found them could publish something called  a “reply”. This resignation appears to be a first. Wagner chucked his job without even so much as phoning Spencer or Braswell, which makes you wonder if it was all a bit convenient.
