Comment: Re:There's already a Tesla museum, in Belgrade. (Score 1) 47

It wouldn't have done what he envisioned, but it could well have proven to be the worlds' first VLF radio station.

Marconi already had VLF working, sort of, before Wardenclyffe was built. Marconi's R&D approach was to transmit across short distances, test and improve the hardware, then try longer distances. Over a few years, he slowly worked up from across the room to across the ocean. Less grandiose than Tesla, but more successful.

Tesla is said to have assisted in the construction of the 1913 Telefunken VLF station on Long Island, but the IRE Journal article doesn't mention him. Telefunken built a VLF antenna much the way one would be built today - a simple guyed tower resting on an insulator base, with wires spreading outward to a circle of poles. They only used 35KW, instead of Tesla's 200KW. The station communicated with a similar station in Germany.

The Tesla Museum already exists.

Tesla did great work with AC generators and motors. Most common AC motors today still use approaches he invented. That's his legacy.

Wardenclyffe, though, is a monument to failure. From his patents, you can read how he thought it would work. He thought the ionosphere was a conductive layer. The Wardenclyffe tower was supposed to punch power through the atmosphere to that conductive layer, so that signals and maybe power could be received elsewhere.

The ionosphere does not work that way. Tesla's tower would have done nothing useful, although with 200KW at 20KHz going in, it probably could have lit up fluorescent lamps and gas tubes for some distance around. Since the location is now surrounded by a housing subdivision, rebuilding the tower and powering it up would annoy the neighbors.

See my 2010 paper "'Places' spam - the new front in the spam wars." As I wrote back then, "The two phases of spamming Google Places are the insertion of fake business locations and the creation of fake reviews. Both are embarrassingly easy." That hasn't changed.

Google doesn't fix this 4-year-old problem because Google makes money from bad search results. If search results take you directly to the business selling whatever it is you want, Google makes no money. If you're detoured through some Demand Media content farm, Google makes ad revenue. If you get fed up with being sent to ad-choked sites and click on a Google ad, Google makes money. Organic search that sucks is a fundamental part of Google's business model.

Technically, it's straightforward to fix this. Business data has to be checked against sources businesses can't easily manipulate, such as business credit rating companies. A business that reports fake store locations to Dun & Bradstreet or Experian will soon have a very low credit rating.

Bing or Yahoo could beat Google at search quality. They have the same spam problem, but it doesn't make them money. That's because Google has most of the third-party advertising market. Web spam on Bing drives traffic mostly to sites with Google ads, not Bing ads.

The real search engines are Google, Bing, Baidu (China) and Yandex (Russia). Everybody else, including Yahoo, is a reseller. Yandex has been doing some interesting stuff lately with linkless search ranking, and Baidu just opened a Silicon Valley office.

Yahoo's Marissa Mayer announced last January that Yahoo was getting back into search. (They've been reselling Bing since 2009.) That appears to have been a bluff to get a better deal from Microsoft. There's no indication of Yahoo actually building a search engine. No relevant job ads, no data center buildout, no increased crawling by Yahoo bots, no high-profile hires, no buzz in Silicon Valley.

Bing ought to be doing better than it is, but they're reported to have management problems. Every year, there's new top management at Bing, and it doesn't help.

I'm listening to the recording of the radio communications. The drone was over 2000' altitude. At first, the cops in the helicopter aren't sure what they're seeing, and they first think it's a fast-moving aircraft in a vertical climb, over the East River. It has red and green lights, like aircraft do. They ask La Guardia ATC radar what they're seeing. ATC isn't seeing it on radar. Then they get closer and see it's a drone of some kind. In a few minutes it's over the George Washington Bridge, miles from the East River.

Once the guys who were operating them were caught, the cops are on the air discussing what to charge them with. The cops on the ground call them "tiny little toys". There's some discussion of "if it's over 1000', it's reckless". The cops aren't quite sure what to charge them with.

The FAA can certainly have them prosecuted. They were operating a drone in class B controlled airspace. That's serious, and dumb. Here's the New York City airspace chart. (Yes, there's actually a VFR corridor over the Hudson River; it's permitted to fly along the river at up to 1300' altitude. There used to be one over the East River, too, but after some jock slammed a light plane into a Manhattan apartment building by going too fast there, it was closed to VFR traffic. These drone operators didn't stay in the VFR corridor, and probably had no clue where it was anyway.)

The drone guys were lucky. LGA has two intersecting runways, 4-22 and 13-31. The one in use depends on wind direction. The approach to 13 and the departure from 31 are over where the drones were operating. LGA happened to be using 4-22 that day. If the other runway had been in use, there would have been a large plane in the area ever 45 seconds or so.

+ - Maldives Denies Russian Claims That Secret Service Kidnapped A Politician's Son

Submitted by Rei
Rei (128717) writes "As was previously reported here, the Russian government has accused the US Secret Service of kidnapping the son of ultranationalist LDPR MP Valery Seleznev in the Maldives. The son, Roman Seleznev, stands accused of running one of the world's largest carding operations, with others charged in the affair having already been convicted; however, Roman had until recently been considered out of reach in Russia. Now the Maldives has struck back against these claims, insisting that they arrested him on an Interpol Red Notice and transferred him to the US, as they are legally required as an Interpol member state to do. “No outsider came here to conduct an operation,” president Abdulla Yameen stated. “No officials from another country can come here to arrest anyone. The government has the necessary documentation to prove it.”"

He said ice sheet. So we're supposed to ignore what he actually said and assume he meant something completely different? Um, no.

"I am not well read in this department" - wait a minute, you can give exact cites for research papers on sea ice, but don't even have a *general* conception of what percentage of the Antarctic ice sheet is gaining versus what is losing? Something tells me you're just grabbing cites you've never even read from denier websites.

Let me help you out with ice sheet. Pretty much all of the East Antarctic ice sheet is gaining, while pretty much the only area losing is the Antarctic peninsula and surrounding areas in West Antarctica. Now, they're losing *mass* a lot faster per unit area than the east is gaining mass, but in terms of area, the overwhelming majority of Antarctica is gaining ice. Because it almost never gets above freezing there, even in a warming world.

The 2010 paper was evaluating the failed CMIP5 predictions

If you'd actually read the paper, which you clearly haven't, you'd know that they themselves did the CMIP5 runs, it's not CMIP5 runs that had been done earlier. Do you even have a clue what CMIP5 stands for? Coupled Model Intercomparison Project Phase 5. As in, "there were four freaking phases that came before this one". CMIP5 is comprised of all of the latest models from all over the world. They didn't even start planning CMIP5 unitl September 2008. Your notion that this is some sort of review of old climate predictions just shows how terrible your understanding is of what you're talking about and how you don't actually read the papers that you cite, that you're just simply grabbing them from whatever denialist trash websites you read.

First, that's a paper from 2010. How was a paper from 2010 supposed to be "predicting" anything about what scientists in the past thought?

Secondly, and more importantly, I had been responding to Archangel Michael, who was talking about the thickness of the Antarctic ice sheet, not Antarctic sea ice. So your link about pack ice is totally irrelevant.

But hey, let's switch topics totally and talk about sea ice, since you seem to want to. Here's how the IPCC sums up all papers on the modelling of antarctic sea ice, including this one:

Whereas sea ice extent in the Arctic has decreased, sea ice extent in the Antarctic has very likely increased. Sea ice extent across the Southern Hemisphere over the year as a whole increased by 1.3– 1.67% per decade from 1979–2012 with the largest increase in the Ross Sea during the autumn, while sea ice extent decreased in the Amundsen-Bellingshausen Sea. The observed upward trend in Antarctic sea ice extent is found to be inconsistent with internal variability based on the residuals from a linear trend fitted to the observations, though this approach could underestimate multi-decadal variability. The CMIP5 simulations on average simulate a decrease in Antarctic sea ice extent , though Turner et al. (2013) find that approximately 10% of CMIP5 simulations exhibit an increasing trend in Antarctic sea ice extent larger than observed over the 1979-2005 period. However, Antarctic sea ice extent variability appears on average to be too large in the CMIP5 models . Overall, the shortness of the observed record and differences in simulated and observed variability preclude an assessment of whether or not the observed increase in Antarctic sea ice extent is inconsistent with internal variability. Based on Figure 10.16b and (Meehl et al., 2007b), the trend of Antarctic sea ice loss in simulations due to changes in forcing is weak (relative to the Arctic) and the internal variability is high, and thus the time necessary for detection is longer than in the Arctic.

Weak trend, short observed record, and high internal variability in the simulations. Which shouldn't be surprising, sea ice is a lot harder to model than ice sheet thickness, which really only has three main parameters - snowfall, melt/sublimation, and outflow, and the short observed record is due to how few people historically have navigated antarctic waters vs. arctic.

But again, to reiterate the primary point: the conversation you jumped into was about ice sheet thickness, not sea ice.

I'm sorry, I just read through that paper, and nowhere in it does it say that a decline in Antarctic ice is a forecast of AGW. That's one of the worst examples of "proof by ghost reference" I've ever seen. Not to mention that the paper is mainly focused on the Antarctic Peninsula, the one place that actually gets melt on more than super-rare occasions and juts into a different climate zone.

Go right ahead and point me to where a decline in Antarctic ice was a forecast of AGW.

You do know that - below freezing - there's an inverse correlation between temperature and snowfall, don't you? And I really hope you know that it's very rare that temperatures rise above freezing in the vast majority of Antarctica, whether you add a couple degrees to the temperature or not, right? Or did you not know / ever consider that?

Just because you didn't realize something that should have been really bloody obvious to you doesn't mean it was a scientific prediction by your straw-man scientists.
