Peter Gleick’s “truly flabbergasting” lapse of judgement.
Gleick has done enormous damage to his cause and his own reputation, and it’s no good to say that people shouldn’t be focusing on it. If his judgement is this bad, how is his judgement on matters of science? For that matter, what about the judgement of all the others in the movement who apparently see nothing worth dwelling on in his actions?
When skeptics complain that global warming activists are apparently willing to go to any lengths–including lying–to advance their worldview, I’d say one of the movement’s top priorities should be not proving them right. And if one rogue member of the community does something crazy that provides such proof, I’d say it is crucial that the other members of the community say “Oh, how horrible, this is so far beyond the pale that I cannot imagine how this ever could have happened!” and not, “Well, he’s apologized and I really think it’s pretty crude and opportunistic to make a fuss about something that’s so unimportant in the grand scheme of things.”
After you have convinced people that you fervently believe your cause to be more important than telling the truth, you’ve lost the power to convince them of anything else. [emphasis in original]
As I’ve said repeatedly, until the climate community stops circling the wagons to protect the liars and frauds that pepper their field, no one is going to believe anything they say, even when they are right. Worse, their dishonesty is continuing to do serious harm to the field of science itself.

Mapping the surface of an extrasolar planet light years away. From the paper’s abstract [pdf]:
We use archived Spitzer [Space Telescope] data of [the star] HD189733 … encompassing six transits, eight secondary eclipses, and a phase curve in a two-step analysis. The first step derives the planet-star system parameters. The second step investigates the structure found in eclipse scanning, using the previous planet-star system parameter derivation as Gaussian priors.
We find a 5-sigma deviation from the expected occultation ingress/egress shape for a uniform brightness disk, and demonstrate that this is dominated by large-scale brightness structure and not an occultation timing offset due to a non-zero eccentricity. Our analysis yields a 2D brightness temperature distribution showing a large-scale asymmetric hot spot whose finer structure is limited by the data quality and planet orbit geometry. [emphasis mine]

At last! The ISS is to finally going to get an experimental centrifuge.
I have studied at length all the research done on all the space station ever launched, from Skylab, all the Russian Salyut stations, Mir, and now ISS, and from I could tell, only once was a centrifuge experiment put in space, by the Russians. Though the centrifuge was small and the results inconclusive, they suggested that even the addition of a truly miniscule amount of force could significantly mitigate the effects of weightlessness on plants and materials.
To finally get an experimental centrifuge on ISS is wonderful news. In order to build an interplanetary spaceship as cheaply and as efficiently as possible using centrifugal force to create artificial gravity we need to know the minimum amount of centrifugal force we need. Less energy will probably require less complex engineering, which should also require less launch weight to orbit, lowering the cost in all ways.

Making buildings invisible to earthquakes.
The manslaughter trial of six scientists and one government official continued yesterday in Italy over their reassurances to the public prior to a deadly earthquake in 2009.
Guido Bertolaso, former head of the Department of Civil Protection and De Bernardinis’s direct superior, had not been indicted and was originally expected to appear as a witness. But a few weeks ago a wiretap revealed that he had apparently set up the meeting to convey a reassuring message, regardless of the scientists’ opinion. He also seemed to be the source of the “discharge of energy” statement. He thus found himself under investigation and, at the beginning of the hearing, he was officially notified that he too may soon be formally indicted for manslaughter.
Bertolaso was asked by the prosecutor to explain that telephone conversation. He defended himself by saying that by defining the meeting as a “media move”, he was not trying to downplay risks but rather to put some order into the contradictory information that was reaching the citizens in those days. In particular, he referred to Giampaolo Giuliani — a laboratory technician and amateur seismologist who was alarming the population with claims that a major shock was coming — and to a newspaper article that had misquoted some Civil Protection experts and stated that the shocks would soon be over. The meeting, he said, was meant to make clear that both were wrong and that no deterministic prediction could be made. [emphasis mine]

For its second attempt to launch the Orbiting Carbon Observatory, NASA has finally decided to dump Orbital Sciences’ Taurus XL rocket, the same rocket that failed on two previous launch attempts.
The decision to change launch rockets will delay launch by at least a year. Still, this is better than losing a third research satellite.
In a preprint paper published today on the Los Alamos astro-ph website and accepted for publication in the Journal of Atmospheric and Solar-Terrestrial Physics, Norwegian scientists have found a strong correlation between the length of the solar sunspot cycle and the Earth’s temperature during the following cycle. From the abstract:
Relations between the length of a sunspot cycle and the average temperature in the same and the next cycle are calculated for a number of meteorological stations in Norway and in the North Atlantic region. No significant trend is found between the length of a cycle and the average temperature in the same cycle, but a significant negative trend is found between the length of a cycle and the temperature in the next cycle. This provides a tool to predict an average temperature decrease of at least 1.0 ◦ C from solar cycle 23 to 24 for the stations and areas analyzed. We find for the Norwegian local stations investigated that 25–56% of the temperature increase the last 150 years may be attributed to the Sun. For 3 North Atlantic stations we get 63–72% solar contribution. [emphasis mine]

Their paper finds that if a particular sunspot cycle is longer with less activity, the climate will show significant cooling during the next cycle.

Is Venus’s day getting longer?
In the 1980s and 1990s, the Venera and Magellan orbiters made radar maps of the surface of Venus, long shrouded in mystery as well as a dense, crushing and poisonous atmosphere. These maps gave us our first detailed global view of this unique and hostile world. Over its four-year mission, Magellan was able to watch features rotate under the spacecraft, allowing scientists to determine the length of the day on Venus as being equal to 243.0185 Earth days. .
However, surface features seen by Venus Express some 16 years later could only be lined up with those observed by Magellan if the length of the Venus day is on average 6.5 minutes longer than Magellan measured. This also agrees with the most recent long-duration radar measurements from Earth.
Ed Weiler quit NASA in September because of the cuts to the Mars planetary program that the Obama administration will announce on Monday.
Weiler was NASA’s chief science administrator for most of the past thirty years.
As I have already noted, the programs that NASA shouldn’t cut are its planetary and astronomy programs. Far better to dump the Space Launch System, which eats up a lot more cash and will end up producing nothing. By doing so you would not only reduce NASA’s actual budget — thereby saving the federal government money — you could simultaneously increase the budgets of the planetary and astronomy programs.
The boycott of science journal publisher Elsevier has now grown to almost 5,000 scientists.
