Remember that "Hiatus" in Anthropogenic Climate Change from 1998-2012?

Not so much.

The reports of a plateau in we saw were due to a change in instrumentation and methodology.

Specifically, in the mid 1990s, ocean water temperature reporting moved from ships cooling water intake data to dedicated free-standing buoys.

It turns out that there is significant heating present in the ships that is not present in the newer methods:

Nope, climate change didn't pause for about 15 years, scientists say – again. But just how did that misunderstanding happen?

From around 1998 to 2012, the rise in global temperatures seemed to plateau, according to NOAA's Extended Reconstruction Sea Surface Temperature (ERSST) dataset.

To most climate scientists, this so-called hiatus was another puzzle of our complex climate system for them to work out. But to people who were already skeptical of global warming, this data was evidence for the idea that human-induced climate change is a hoax.

But the data itself was unsound, scientists now say. There is no evidence of a hiatus.

………

For decades, sea surface temperatures were measured on ships, using water sucked into a ship's engine room. But in the mid-1990s, scientists began deploying a new strategy across the world's oceans: thermometers on buoys. By the late 1990s, this method had taken off, Hausfather says.

But here's the catch: the buoys bobbing on the surface of the sea take colder measurements than those taken within the warm engine room of a ship. And, in the ERSST version 3b, scientists had just tacked on the buoy data without adjusting for that difference.

When NOAA scientists realized the problem, they calculated that difference and weighted the data differently, resulting in ERSST version 4. And, according to their calculations, version 4 showed more than twice as much warming, on the global scale, as version 3b.

………

Instead of looking at all the data mashed together, Hausfather and his colleagues studied the trends in the data from different sources separately, including data from ships, buoys, satellites, and drifting robots called Argo floats.

"The authors did a great job of inter-comparing independent and semi-independent SST data sets," Thomas Karl, the lead author on the 2015 NOAA paper and former director of NOAA's National Centers for Environmental Information, writes in an email to the Monitor. "Their results show the importance of independent measurements to clarify observational uncertainties."

"This paper further allays any qualms that there may have been scientific errors or any non-scientific agendas," Kevin Trenberth, senior scientist in the Climate Analysis Section at the National Center for Atmospheric Research, who was not part of either paper, writes to the Monitor. "Lamar Smith owes Tom Karl an apology."
So from the late '90s to the early teens, there was a transformation in the sources of the data, and if you view the data filtered by source, you see the ΔT, but if you view it in aggregate, it shows a moderation.

Good science, but bad news.  We are in for a world of hurt.

Tweet of the Day



The argument was bogus when John John Lewis made it, and it is bogus now.

I have no idea what Clinton had on the Democratic Party establishment, they really did sell their soul to her during the primaries.

The Term Here is Kafkaesque

In Supreme Court arguments, the state of Colorado is arguing that it has no obligation to refund fines collector after a defendant is exonerated:
The Supreme Court on Monday seemed deeply skeptical of a Colorado law that makes it hard for criminal defendants whose convictions are overturned to get refunds of the fines and restitution they had been ordered to pay.

The justices were helped by the forthright presentation of the state’s solicitor general, Frederick R. Yarger, who did not shy away from the more extreme implications of his argument. Money taken from defendants after valid convictions belongs to the state, he said.

A Colorado law requires people cleared by the courts to file separate civil suits and prove their innocence with clear and convincing evidence in order to obtain reimbursement. But Mr. Yarger said the state was under no obligation to do even that much. He said the state was not only free to impose onerous procedures, but could also enact a law making exonerated defendants forfeit the money entirely.

Chief Justice John G. Roberts Jr. asked if the state could impose a $10,000 fine on everyone convicted of a crime and refuse to return the money if the convictions were later overturned.

Mr. Yarger said yes. Just as there is no need to pay people for the time they spend in prison after their convictions are reversed, he said, there is no need to reimburse them for fines and fees. “The assumption is that the deprivation of both the liberty and the property at the time of conviction is lawful, and that the property passes into public funds,” he said.

………

The Colorado law was challenged by Shannon Nelson and Louis Madden, who had been ordered to pay thousands of dollars in fees and restitution after they were convicted of sex offenses. After their convictions were overturned, they filed motions in their criminal cases seeking refunds of what they had paid.

The Colorado Supreme Court ruled against them, saying that their trial courts lacked authority to compensate them. Under the state’s law, the State Supreme Court said, they had to file a new civil suit and meet a heightened burden of proof.

Stuart Banner, a lawyer for Ms. Nelson and Mr. Madden, said the state’s approach amounted to “charging people money for the privilege of trying them unlawfully.”
This may be stating the obvious, but when the state subverts the administration of justice such that it becomes little more than a protection racket, you have a Mafia state.

Not Enough Bullets

Amazingly enough, the story shows the subjects of the story even more self-absorbed and clueless than the headline dows:

Davos Elite Fret About Inequality Over Vintage Wine and Canapés
You morons broke the world.

You were born on 3rd base and though that you hit a triple.

You are not deserving, you are lucky.
  • You won the parent lottery.
  • You won the nationality lottery.
  • You won the social class lottery.
Now try and do something to make the world a better place for the rest of us.

    Another John Carpenter Moment

    Yesterday, I noted that after almost 35 years, I was finally more horrified and disgusted than Palmer was in the 1982 version of the movie The Thing.

    Who knew that the mixture of horror and disgust at Betsy Devos would be exceeded in the next day.

    Specifically Judith Miller tweeted her horror at the commutation of Chelsea Manning's sentence:


    This engendered the following observation from Jason Concepcion:

    For those of you who don't recall, during the run-up to the invasion of Iraq, Judith Miller, then a New York Times reporter was desperately shilling for the Bush administration (Google Judith Miller Curveball) and was typing up anything and everything that she could find, without regard to classification to help them.

    So, 4,424 US Soldiers dead, and around 500,000 Iraqis dead, because of her casual handling of classified material, and her even more casual handling of the truth, and suddenly, she's concerned about the body counts.

    Why she isn't selling perfume one cash register over from Janet Cooke for a living is completely beyond me.

    H/t Naked Capitalism.

    Still a Few Bugs in the System

    Some neuroscientists decided to see if the latest neuroscience tools could handle a simpler case than the human brain.

    They chose a 40+ year old CPU, and they failed abysmally:

    In 2014, the US announced a new effort to understand the brain. Soon, we would map every single connection within the brain, track the activity of individual neurons, and start to piece together some of the fundamental units of biological cognition. The program was named BRAIN (for Brain Research through Advancing Innovative Neurotechnologies), and it posited that we were on the verge of these breakthroughs because both imaging and analysis hardware were finally powerful enough to produce the necessary data, and we had the software and processing power to make sense of it.

    But this week, PLoS Computational Biology published a cautionary note that suggests we may be getting ahead of ourselves. Part experiment, part polemic, a computer scientist got together with a biologist to apply the latest neurobiology approaches to a system we understand far more completely than the brain: a processor booting up the games Donkey Kong and Space Invaders. The results were about as awkward as you might expect, and they helped the researchers make their larger point: we may not understand the brain well enough to understand the brain.

    On the surface, this may sound a bit ludicrous. But it gets at something fundamental to the nature of science. Science works on the basis of having models that can be used to make predictions. You can test those models and use the results to refine them. And you have to understand a system on at least some level to build those models in the first place.

     ………

    That's where Donkey Kong comes in.

    Games on early Atari systems were powered by the 6502 processor, also found in the Apple I and Commodore 64. The two authors of the new paper (Eric Jonas and Konrad Paul Kording) decided to take this relatively simple processor and apply current neuroscience techniques to it, tracking its activity while loading these games. The 6502 is a good example because we can understand everything about the processor and use that to see how well the results match up. And, as they put it, "most scientists have at least behavioral-level experience with these classical video game systems."

    So they built upon the work of the Visual 6502 project, which got ahold of a batch of 6502s, decapped them, and imaged the circuitry within. This allowed the project to build an exact software simulator with which they could use to test neuroscience techniques. But it also enabled the researchers to perform a test of the field of "connectomics," which tries to understand the brain by mapping all the connections of the cells within it.

    To an extent, the fact that their simulator worked is a validation of the approach. But, at the same time, the chip is incredibly simple: there is only one type of transistor, as opposed to the countless number of specialized cells in the brain. And the algorithms used to analyze the connections only got the team so far; lots of human intervention was required as well. "Even with the whole-brain connectome," Jonas and Kording conclude, "extracting hierarchical organization and understanding the nature of the underlying computation is incredibly difficult."
    Remember, in a microprocessor, a transistor is a transistor is a transistor, in the brain, neurons and ganglia vary from cell to cell.

    This is a valid test of the software, the 6502 is arguably the most thoroughly understood CPU in existence, and Donkey Kong is arguably one of the best understood pieces of software in existence.

    And they still could not do it on a  processor that can access only 64K of RAM.

    We are much further from mapping the brain in any detail than is implied in the mainstream media reports.
