Even if we ignore the carbon (and other toxic) footprint of creating and strewing millions of semiconductor devices across the desert, I really think you need to think about what happens to the formic acid. Left to its own devices, formic acid slowly and spontaneously decomposes to water and...carbon monoxide. Which is unpleasant enough by itself (and a greenhouse gas in its own right), but which in turn is slowly oxidized in the atmosphere right back to...carbon dioxide.

For people who are interested in this sort of thing, the TOXNET entry for americium contains a number of excerpts from published work about the case, medical follow up, and eventual autopsy results. The first six case report entries on that page all involve publications involving McC|uskey; look for entries that refer specifically to "US Transuranium Registry (USTUR) Case 246". Because americium is an alpha emitter that principally deposits in bone, it is the bone and bone marrow that are most affected by exposure, and which show the most lasting (and ongoing) damage.

"...Eight yrs after a 64-year old man was exposed to americium-241 in a chemical explosion/, leukopenia was evaluated by a hematologist. Diagnosis of a possible hypoproliferative, myeloproliferative, or myelodysplastic syndrome was considered...."

"...The bone marrow of /USTUR Case 246/ had been substantially damaged by alpha-irradiation from americium, principally on the bone surfaces. A ... finding was a marked decrease in bone marrow cellularity associated with dilatation of blood sinusoids. The severity of these effects varied according to site and was greatest in the vertebral body, where the marrow was almost acellular, and least in the clavicle. In addition, extensive peritrabecular marrow fibrosis was present in some bones, including the rib and clavicle. ... Fibrosis is a common observation in bones irradiated by bone-seeking radionuclides and has been linked to bone sarcoma induction...."

"...The bones examined were the patella, clavicle, sternum, rib, vertebral body and ossified thyroid cartilage; all showed evidence of radiation damage. The cellularity of most bones was reduced, and little evidence of recent active bone remodeling was seen in any bone other than the vertebra, as concluded from the redistribution of the americium in the vertebral body. In several bones, the architecture was disrupted, with woven bone, abnormal appositional bone deposits, bizarre trabecular structures and marked peritrabecular fibrosis. Growth arrest lines were common. When compared with trabecular bone modeling, that of cortical bone in the rib appeared less disrupted. Overall, the results obtained are consistent with those observed in dogs at a similar level of actinide intake...."

In other words, he was 'lucky' that this accident occurred when he was in his mid-sixties, and that he managed to die of heart disease in his mid-seventies. If the patient had been forty years old instead, he likely would have been looking at a cancer of either the bone (an osteosarcoma or some such, and probably at multiple sites if he lived long enough) or the blood-forming cells (leukemia of some sort).

Germany doesn't sell daytime power "at a loss". Power at night on the European grid doesn't sell for high prices. Show some citations, ye of eyebrow raising claims.

I'm assuming that he's filing suit in California because the Wikimedia Foundation headquarters is there, and it's easier to do it that way than to file fifty-four separate suits (four named editors plus 50 John Does) in 54 different jurisdictions. Further, Barry's lawyers can argue (don't know if it will work) that personal jurisdiction exists for all the defendants, as all of them were engaged in a relationship with the Foundation. Otherwise their case gets a lot messier and a lot more expensive.

Of course, not every lawsuit that is filed is followed through to trial and judgement. (Just as a general observation not related to this particular case -- not every lawsuit is filed with the expectation or intent to follow it through to trial. Lawsuits are often part of PR strategies, sometimes simply to chill public discussion on a particular topic. A big flashy statement of claim is sometimes just a route to a quiet small- or no-money settlement and a gag order.)

And heck, your original point stands. Suing U.S. defendants in a U.K. court would be pretty transparent libel tourism; it wouldn't have a beneficial PR effect, and judgements wouldn't be readily enforceable in the States.

It's the ambiguity of language that's at fault here. The key to the sentence you mentioned is "like normal matter". Normal matter absorbs electromagnetic radiation, increasing its energy level, and drops back to lower energy levels by emitting electromagnetic radiation. Thus, normal matter interacts with light. This is a different physical process than the emission of light due to decay of the particle itself.

And while we haven't pinned down dark matter by any means, it's much more than a stab in the dark. For one, there are known particles--neutrinos--that do not interact via the electromagnetic force, so the idea of unknown particles with the same property isn't unrealistic.

Then, there are clues from many different directions that point to something consistent with matter that interacts gravitationally but not electromagnetically. These include calculations concerning the total matter in the universe, galaxy cluster formation, the rotational speed of stars on the out edge of galaxies, etc.

The hypothesis is not that the X-Rays are interacting with this type of dark matter. It is that the decay of this type of dark matter generates X-Rays.

Er...what does the warrantless, essentially-unrestricted search and/or seizure of personal electronic devices - generally belonging to U.S. citizens, legal residents, and legitimate travellers - have to do with immigration policy?

That wasn't the worst sentence in history, but it's got to be right up there.

I'll leave aside your amusingly delusional implication that unwarranted invasions of privacy somehow didn't happen - or weren't attempted by law enforcement with similar enthusiasm and vigour - under the preceding 43 Presidents...

Nuclear is for a big chunk of base load capacity--plants that take days or weeks to start up and shut down, and so run essentially continuously at their rated output. (Coal plants fill essentially the same niche in fossil-fuel-based generation.) Wind (and solar) stack on top of that; these are variable output plants that can be switched in and out of service quickly as needed to meet demand. Gas turbines, while not emission free, are more efficient (in terms of energy output per ton of carbon emissions) than coal or oil burners, and can be spun up relatively quickly (in a few minutes) to meet spikes in demand. They're a compromise - good fuel efficiency but also high cost - that would be used for a few hours a day, or a few days a month, to fill in gaps in supply.

That is true, and interesting...but beside the particular point at issue here. The SPEECH Act (ugh) deals with defamation suits against U.S. citizens and residents filed in foreign courts. The case here is the mirror image situation: a case filed in the U.S. against a (hypthetical) overseas defendant.

There is, however, an expectation that Wikipedia editors will present information about a person (or any topic, for that matter) in a way that is proportionate to its relevance and importance. Under- or (especially) over-stating the importance of particular facts to give a coloured perspective isn't on; see the section of Wikipedia's neutral-point-of-view policy on Due and undue weight.

In other words, if George W. Bush's biography opened with

It would be an undeniably true statement that nevertheless failed to comply with Wikipedia policy.

Similarly, Wikipedia's policy against using Wikipedia as a venue to publish original research specifically forbids "synthesis of published material". That is, you can't cherry-pick a bunch of sources (or parts of sources) and use them to state - or imply - a particular novel conclusion that hasn't been presented by a reliable, independent source. I could go on at length, but suffice it to say that Wikipedia content is ruled by far more than "It appeared in the newspaper so we have to put in Wikipedia".

Here's the current article: Medieval Warm Period. It has a couple of pages of detailed text, a pair of graphs of temperature records, and three photographs of locations or artifacts relevant to the MWP's effect on human history. The article has 41 footnotes, mostly to peer-reviewed journal articles.

Five years ago: 2009 version. A little over a page, one graph, one photo. 25 footnotes.

For fun, ten years ago: 2004 version. Six paragraphs (three of which are a single sentence). Zero figures, zero photographs. Just 4 inline references.

Scrolling through the article's editing history I don't find any period where anyone "erased" the MWP, aside from some short-lived vandalism. At no point is there any intimation in the article that the MWP didn't occur or was otherwise not a real thing. The article appears to have grown steadily in length, quality, and detail over the last decade, but its central points appear to have remained essentially unchanged. Your comment, however, appears quite typical of climate change deniers--boldly stating things that are patently untrue in order to gain the emotional support of people who don't fact-check you, while wasting the time of the people who do.

The defamation laws and precedent which apply depend on the jurisdiction in which suit was filed, not on where the defendants live. And the second sentence of the article indicates that suit was filed in Ventura County Superior Court: in other words, California.

(Indeed, it might be preferable for a defendant to live in the UK; depending - very much - on the particular details of the case, a California court may dismiss a defamation suit against a UK defendent due to the court's lack of personal jurisdiction. Or, in the event of judgement in favour of the plaintiff against a large number of defendants, the plaintiff may decide that actually trying to extract payment from a person in another country isn't worth the time, effort, and additional billable hours.)

Indeed. Existing nuclear wins because the metric EPA is using for compliance includes a portion of MWh generated by existing nuclear in the denominator (something like 5%). Therefore, keeping existing nuclear online will help states comply with 111(d). Existing nuclear is a winner under 111(d) -- including the nuclear units under construction in GA, SC, and TN.

New nuclear? New nuclear will never win. It's simply can't hold a candle to PV and wind in an unsubsidized market. New wind is cheap enough now, and new PV trending that way that it's not worth the tremendous risk associated with a long, large, non-scalable, expensive construction project.

If your bills are going up 50%, its because your electric company is spending lots of money on existing coal plants so they emit less SO2, NOx, PM, and Hg. Of course, they'll emit about the same amount of CO2. Utilities that haven't insisted on coal coal coal haven't seen substantial increases in rates.

This is a generality -- individual utilities may have rate increases for other reasons, but very, very few utilities have had rates go up by 50% within the past 3 years. In fact, many utilities have had rate decreases.
