Hillary’s Email Woes

18 Comments

…deepen:

The latest release of roughly 6,300 more pages of emails is just the latest installment of a prolonged disclosure process that has proved to be painful for Clinton’s presidential campaign. The roiling controversy has opened up the Democratic front-runner to accusations that she was trying to dodge public records rules and that she put sensitive material at risk — allegations Clinton denies.
Wednesday’s release marks the first time the State Department itself has deemed messages in Clinton’s account to warrant protection at the SECRET level — the middle tier of the national security classification system. State earlier classified one Benghazi-related message SECRET, but did so at the request of the FBI.

Well, if she denies it, that should settle it.

The Uncertainty Of Climate Sensitivity

18 Comments

…and its implications for the Paris “negotiations”:

In my previous post Climate sensitivity: lopping off the fat tail, I argued that it is becoming increasingly difficult to defend high values of ECS. However, the uncertainty is sufficiently large that we can’t really identify a meaningful ‘best value’ of sensitivity, or rule out really high values.

A key issue is that emerging estimates of aerosol forcing are considerably lower than what was used in the AR5 determinations of ECS, implying lower values of ECS than was determined by the AR5.

This uncertainty in ECS makes emission targets rather meaningless. It will be interesting to see how this uncertainty is factored into the Paris negotiations

Note, there are other papers on this general topic that are in the review process, I expect a spate of such papers to appear during the next month.

Paris is doomed to failure, thankfully.

NASA’s Bureaucracy

2 Comments

This comment over at NASA Watch is a pretty good description of the problem, on the 57th anniversary of the agency transforming from the NACA (which it needs to return to) to NASA:

In another current post on NW, Wayne Hale laments that the lengthy list of specifications is going to kill the commercial crew effort. Why this lengthy list of specs? Maybe because the NASA people who wrote the program requirements had no actual experience in developing any space hardware, and they did not know which specs to select, so they just included them all?

I should also note that it is not because more experienced and more qualified people were not available in these instances of program management, vehicle design, or spec writing. There were people with experience in Shuttle, Spacehab (commercial), Mir systems development, and with DOD programs, but the NASA management went with people they “knew” despite their lack of experience. You can look all the way to the top of the program, the AA for manned spaceflight, and he has little more experience, and so how can he provide the guidance for others to “learn the trade”. In fact he appears to have been responsible for naming a large number of his contemporaries, all from his old organization, payload operations, to leading positions. I don’t think they’ve worked out too well.

The mission ops directorate has the right idea-they require people to be certified and as they get certified their careers progress and they move from document writer to flight controller to flight director. The other technical/engineering disciplines do not have this and so we wound up in a situation where virtually anyone with a degree can be selected for almost any position.

Now, especially after 3 decades of ISS, you have the big bureaucracy in which the main experience base is in meeting attendance. And the people without the experience in the top positions are fearful of the people who actually have any education and experience. This is a corrupt bureaucracy.

That Wayne Hale post, from five years ago, is sadly prophetic.

Blue Origin

The company announces that it’s completed a hundred successful tests of its staged-combustion turbomachinery. It’s a little misleading to show a full-engine test, with shock diamonds, though. Also, they don’t say if there have been any failures. Particularly of the rapid-unscheduled-disassembly type.

Meanwhile, Aerojet Rockedyne continues to beg for money.

[Update a few minutes later]

George Sowers just tweeted to me that these were subscale tests, not full scale. Hopefully, that’s next.
