Cause of Global Warming 'Hiatus' Found Deep In the Atlantic 2

vinces99 writes with news about a study that may account for a slowdown in air temperature rises. Following rapid warming in the late 20th century, this century has so far seen surprisingly little increase in the average temperature at the Earth's surface. More than a dozen theories have now been proposed for the so-called global warming hiatus, ranging from air pollution to volcanoes to sunspots. New research from the University of Washington shows the heat absent from the surface is plunging deep in the north and south Atlantic Ocean, and is part of a naturally occurring cycle. The study is published in Science. Subsurface ocean warming explains why global average air temperatures have flatlined since 1999, despite greenhouse gases trapping more solar heat at the Earth's surface. "Every week there's a new explanation of the hiatus," said corresponding author Ka-Kit Tung, a UW professor of applied mathematics and adjunct faculty member in atmospheric sciences. "Many of the earlier papers had necessarily focused on symptoms at the surface of the Earth, where we see many different and related phenomena. We looked at observations in the ocean to try to find the underlying cause." What they found is that a slow-moving current in the Atlantic, which carries heat between the two poles, sped up earlier this century to draw heat down almost a mile (1,500 meters). Most previous studies focused on shorter-term variability or particles that could block incoming sunlight, but they could not explain the massive amount of heat missing for more than a decade.

Now of course gas stations don't always have fully occupied pumps and that's the point, so that almost whenever you arrive, there's a free pump available.

Well, there's likely a pump available. It isn't generally going to be free. Tesla charging stations, however, at least for the time being...

If you thought it was a quick process to build a Supercharger station, you were clearly wrong.

If you thought I thought it was a quick process to build a Supercharger station, you were just as wrong. If you thought I cared about how long it tool them to build such as station, you were wrong about that, too. And if you thought I liked java over c, you were still wrong. I could go on -- likely longer than even I, in the name oif pushing a point until it is completely blunt, am willing to do so, but I will refrain in the interest of keeping the peace.

Anyway, as it turns out, TFS serves as a veritable smorgasbord of potential if-then-huhs that can only be explained by somewhat bemused turtles all the way down.

At this time, I'd like to take a moment to thank my dear friend Yurtle.

Because a city in Utah had already started a system and had it in place, they were able to lease it to Google, which Google did.
If anything, that shows that gov. helping its citizens, and then working businesses, goes MUCH FURTHER, than allowing large business monopolies.

No doubt that is what ppl like you said when the wright brothers flew about 100' just over 110 years ago.
And it is the same thing that was said by others like you when America made the lithium Batteries.
Or when Goddard flew the first liquid rocket.

How Does Tesla Build a Supercharger Charging Site? 48

cartechboy writes Tesla's Superchargers are the talk of the electric car community. These charging stations can take a Model S battery pack from nearly empty to about 150 miles of range in around 30 minutes. That's crazy fast, and it's nothing short of impressive. But what does it take to actually build a Tesla Supercharger site? Apparently a lot of digging. A massive trench is created to run high-capacity electric cables before the charging stations themselves are even installed. A diagram and photos of the Electric Conduit Construction build out have surfaced on the Internet. The conduits connect the charging stations to a power distribution center, which in turn is connected to a transformer that provides the power for charging cars. It took 11 days to install the six charging stalls in Goodland, Kansas. If you thought it was a quick process to build a Supercharger station, you were clearly wrong.

tlhIngan writes Municipal broadband is in the news again — this time Chief of Staff Matthew Berry, speaking at the National Conference of State Legislatures, has endorsed states' right to ban municipal broadband networks and warned the (Democrat-led) FCC to not do anything that a future Republican led FCC would dislike. The argument is that municipal broadband discourages private investment in broadband communications, that taxpayer-funded projects are barriers to future infrastructure investment.

Sigh
America's central bank HAS dumped $ over the last 3 years. That was to stop what these other nations were doing. Had they not been manipulating, then when we dumped our $, and if they kept theirs at a set amount, then the foreign money to the $ would have dropped (i.e. more $ to the ruppe/won/yuen/etc). That was NOT the case. Instead, it continued rising relative to the $.

Now, as to other moneys, NZ's dollar dropped because the one-way trade with US increased, combined with US$ dumping $ to stop these other nations from trying to sink America. And our central bank has HELPED NZ with that.

When it is considered the main money of the world, no, you can NOT manipulate it easily. To throw China and others off, we DID dump $ on the market, but we also helped allies to overcome the issues with it. OTOH, China, India, Vietnam, etc are suffering massive inflation due to their manipulation.

Gravity isn't science fiction

Of course it is.

We actually do send people into space, and that kind of disaster could sort of happen.

But we didn't send anyone named Dr. Ryan Stone on space shuttle mission STS-157, and none of the other events in the film ever happened... so its CLEARLY fiction.

And it is science fiction because many of the antagonists/obstacles are consequences of the known rules of physics.

It handily meets any definition of science fiction I would ever care to use.

And that's really cool--what seems so much like SF is actually a real-life job that some people do everyday.

We all live moments away from science fiction. A fictional story about the challenge of escaping a car after it goes over a bridge into a river can be science fiction if the accident is modelled according to our understanding of science instead of just done for dramatic effect. The juxtaposition of the vehicles crumple zones with how they'd react hitting a river from 30 feet up, how much time would the occupants REALLY have, how could they REALLY get out... etc.

Most good Science fiction are simply stories about people reacting to their environment within the bounds of their humanity, and the constraints of known science.

That environment can be trumped up with constructs which are not explained... whether its faster than light travel, or an alien race governed by a hive mind... or it can be entirely mundane (as in Gravity or my imagined car accident story).

What makes it science fiction is that once the rules of the environment is established, the characters react to it constrained by the rules of science.

What separates good science fiction from fantasy is that fantasy is not bound to establish and then follow a set of physics. It's free to continually introduce whatever capabilities the characters need as the story needs it. Fantasy follows whatever path the author wishes without constraint. Science fiction's defining characteristic is that the narrative is constrained and driven by known physics or known or speculative physics.

Now you might say, but that's true of James Joyce's Dubliners; it too is constrained by the rules of phyiscs. None of the characters are magical or fantastical and nothing impossible according to known physics happens. And that's true. The difference between science fiction and ordinary (non-fantasy) fiction is that in science fiction the narrative is driven in part by the science. Dubliners narratives are not driven by science.

So even CSI could have been really good science fiction. Except its not, because despite the trappings of science they toss it out the window left and right. Star Trek with its particle-du-jour ... often is science fiction, because you are allowed to "pre-suppose" an alternate physics -- the trick is to play out the rest of the story constrained by it. Star Trek of course, as often as not, also fails to follow the rules it sets out for itself, and so deviates to space-fantasy or something... but many of its good episodes are good SF.

Biology is the only science in which multiplication means the same thing as division.
