Statistical validation of results, as Shaffer described it, simply involves testing the null hypothesis: that the pattern you detect in your data occurs at random. If you can reject the null hypothesis—and science and medicine have settled on rejecting it when there's only a five percent or less chance that it occurred at random—then you accept that your actual finding is significant. The problem now is that we're rapidly expanding our ability to do tests. Various speakers pointed to data sources as diverse as gene expression chips and the Sloan Digital Sky Survey, which provide tens of thousands of individual data points to analyze. At the same time, the growth of computing power has meant that we can ask many questions of these large data sets at once, and each one of these tests increases the prospects than an error will occur in a study; as Shaffer put it, "every decision increases your error prospects." She pointed out that dividing data into subgroups, which can often identify susceptible subpopulations, is also a decision, and increases the chances of a spurious error. Smaller populations are also more prone to random associations. In the end, Young noted, by the time you reach 61 tests, there's a 95 percent chance that you'll get a significant result at random. And, let's face it—researchers want to see a significant result, so there's a strong, unintentional bias towards trying different tests until something pops out. Young went on to describe a study, published in JAMA, that was a multiple testing train wreck: exposures to 275 chemicals were considered, 32 health outcomes were tracked, and 10 demographic variables were used as controls. That was about 8,800 different tests, and as many as 9 million ways of looking at the data once the demographics were considered.

In Cheneyworld, that would be an act of war. So why aren't the Cheneys attacking the German government for its "mindset" problem? Because they have no political interest in weakening that administration, and they do in attacking the American administration. Or they're more scared of Angela Merkel than they are of Barack Obama. Unlike the US, Germany has had a recent successful experience in rolling up a terrorist threat against the country, when the Baader-Meinhof Gang was dealt with as... a criminal conspiracy. If this were a country where other countries' successes at least suggested something to be emulated, that record might be persuasive. But despite our self-image as a nation obsessed with success, some of us, at least, seem more obsessed with making a political point than with pursuing a successful course in dealing with terrorism.

We know that the Obama administration will not go after the banksters that created this global financial calamity. It has been thoroughly co-opted by Wall Street's fifth column, who hold most of the important posts in the administration. Europe has even more at stake and has shown somewhat more willingness to take action. Perhaps our only hope for retribution lies there.

Some might believe the term "banksters" is too mean. Surely Wall Street was just doing its job -- providing the financial services wanted by the world. Yes, it all turned out a tad unfortunate but no one could have foreseen that so many of the financial innovations would turn into black swans. And hasn't Wall Street learned its lesson and changed its practices? Fat chance. We know from internal emails that everyone on Wall Street saw this coming -- indeed, they sold trash assets and placed bets that they would crater. The crisis was not a mistake -- it was the foregone conclusion. The FBI warned of an epidemic of fraud back in 2004 -- with 80% of the fraud on the part of lenders. As Bill Black has been warning since the days of the Saving and Loan crisis, the most devastating kind of fraud is the "control fraud," perpetrated by the financial institution's management. Wall Street is, and was, run by control frauds. Not only were they busy defrauding the borrowers, like Greece, but they were simultaneously defrauding the owners of the firms they ran. Now add to that list the taxpayers that bailed out the firms. And Goldman is front and center when it comes to bad apples. Lest anyone believe that Goldman's executives were somehow unaware of bad deals done by rogue traders, William Cohan reports that top management unloaded their Goldman stocks in March 2008 when Bear crashed, and again when Lehman collapsed in September 2008. Why? Quite simple: they knew the firm was full of toxic waste that it would not be able to continue to unload on suckers -- and the only protection it had came from AIG, which it knew to be a bad counterparty. Hence on March 19, Jack Levy (co-chair of M&As) sold over $5 million of Goldman's stock and bet against 60,000 more shares; Gerald Corrigan (former head of the NY Fed who was rewarded for that tenure with a position as managing director of Goldman) sold 15,000 shares in March; Jon Winkelried (Goldman's co-president) sold 20,000 shares. After the Lehman fiasco, Levy sold over $6 million of Goldman shares and Masanori Mochida (head of Goldman in Japan) sold $56 million worth. The bloodletting by top management only stopped when Goldman got Geithner's NYFed to produce a bail-out for AIG, which of course turned around and funneled government money to Goldman. With the government rescue, the control frauds decided it was safe to stop betting against their firm. So much for the "savvy businessmen" that President Obama believes to be in charge of Wall Street firms like Goldman.

From 2001 through November 2009 (note the date -- a full year after Lehman) Goldman created financial instruments to hide European government debt, for example through currency trades or by pushing debt into the future. But not only did Goldman and other financial firms help and encourage Greece to take on more debt, they also brokered credit default swaps on Greece's debt-making income on bets that Greece would default. No doubt they also took positions as the financial conditions deteriorated-betting on default and driving up CDS spreads. But it gets even worse: An article by the German newspaper, Handelsblatt, ("Die Fieberkurve der griechischen Schuldenkrise", Feb. 20, 2010) strongly indicates that AIG, everybody's favorite poster boy for financial deviancy, may have been the party which sold the credit default swaps on Greece (English translation here). Generally, speaking, these CDSs lead to credit downgrades by ratings agencies, which drive spreads higher. In other words, Wall Street, led here by Goldman and AIG, helped to create the debt, then helped to create the hysteria about possible defaults. As CDS prices rise and Greece's credit rating collapses, the interest rate it must pay on bonds rises-fueling a death spiral because it cannot cut spending or raise taxes sufficiently to reduce its deficit. Having been bailed out by the Obama Administration, Wall Street firms are already eyeing other victims (and for allowing these kinds of activities to continue, the US Treasury remains indirectly complicit, another good reason why one shouldn't expect any action coming out of Washington). Since the economic collapse is causing all Euronations to run larger budget deficits and at the same time is raising CDS prices and interest rates, it is easy to pick off nation after nation. This will not stop with Greece, so it is in the interest of Euroland to stop the vampires now. With Washington unlikely to do anything to constrain Goldman, it looks like the European Union, which is launching a major audit, just might banish the bank from dealing in government debt. The problem is that CDS markets are essentially unregulated so such a ban will not prevent Wall Street from bringing down more countries-because they do not have to hold debt in order to bet against it using CDSs. These kinds of derivatives have already brought down an entire continent -- Asia -- in the late 1990s , and yet authorities are still standing by and basically doing nothing when CDSs are being used again to speculatively attack Euroland. The absence of sanctions last year, when we had a chance to deal with this problem once and for all, has simply induced even more outrageous and fundamentally anti-social behavior. It has pitted neighbor against neighbor -- with, for example, Germany and Greece lobbing insults at one another (Greece has requested reparations for WWII damages; Germany has complained about subsidizing what it perceives to be excessive social spending in Greece). Of course, as far as Greece goes, the claim now is that these types of off balance sheet transactions in which Goldman and others engaged were not strictly "illegal" under EU law. But these are precisely the kinds of "shadow banking transactions" that almost brought down the global financial system 18 months ago. Literally a year after the Lehman bankruptcy -- MONTHS after Goldman itself was saved from total ruin, it was again engaging in these kinds of deals. And it wasn't exactly a low-level functionary or "rogue trader" who was carrying out these transactions on behalf of Goldman. Gary Cohn is Lloyd "We're doing God's work" Blankfein's number 2 man. So it's hard to believe that St. Lloyd did not sanction the activities as well in advance of collecting his "modest" $9m bonus for last year's work.

Solar-powered drip irrigation enhances food security in the Sudano–Sahel documents a field research project which found that: "solar-powered drip irrigation significantly augments both household income and nutritional intake, particularly during the dry season, and is cost effective compared to alternative technologies" Over the decades, irrigation has been shown to greatly increase agricultural productivity. Drip irrigation is spreading rapidly in Africa, with significant benefits. "Drip irrigation delivers water (and fertilizer) directly to the roots of plants, thereby improving soil moisture conditions; in some studies, this has resulted in yield gains of up to 100%, water savings of up to 40–80%, and associated fertilizer, pesticide, and labor savings over conventional irrigation systems" The solar-powered systems, however, look to offer the potential for even better results. From the study on impacts of PVDI systems it was reported: "The women’s agricultural group members utilizing the PVDI systems became strong net producers in vegetables with extra income earned from sales, significantly increasing their purchases of staples, pulses, and protein during the dry season, and oil during the rainy season. Finally, survey respondents were asked how frequently they were unable to meet their household food needs. Based on the frequency and most recent incident, households were assigned a food insecurity score ranging from zero (no problems during the previous year) to one (perpetually unable to meet food needs). This score changed significantly for project beneficiaries, as they were 17% less likely to feel chronically food-insecure. In short, the PVDI systems had a remarkable effect on both year-round and seasonal food access."

By combining a hurricane model and coupled ocean-atmosphere general circulation model to investigate the early Pliocene, Emanuel, Brierley and co-author Alexey Fedorov observed how vertical ocean mixing by hurricanes near the equator caused shallow parcels of water to heat up and later resurface in the eastern equatorial Pacific as part of the ocean wind-driven circulation. The researchers conclude from this pattern that frequent hurricanes in the central Pacific likely strengthened the warm pool in the eastern equatorial Pacific, which in turn increased hurricane frequency — an interaction described by Emanuel as a “two-way feedback process.”�The researchers believe that in addition to creating more hurricanes, the intense hurricane activity likely created a permanent El Nino like state in which very warm water in the eastern Pacific near the equator extended to higher latitudes. The El Nino weather pattern, which is caused when warm water replaces cold water in the Pacific, can impact the global climate by intermittently altering atmospheric circulation, temperature and precipitation patterns.The research suggests that Earth’s climate system may have at least two states — the one we currently live in that has relatively few tropical cyclones and relatively cold water, including in the eastern part of the Pacific, and the one during the Pliocene that featured warm sea surface temperatures, permanent El Nino conditions and high tropical cyclone activity.Although the paper does not suggest a direct link with current climate models, Fedorov said it is possible that future global warming could cause Earth to transition into a different equilibrium state that has more hurricanes and permanent El Nino conditions. “So far, there is no evidence in our simulations that this transition is going to occur at least in the next century. However, it’s still possible that the condition can occur in the future.”�Whether our future world is characterized by a mean state that is more El Nino-like remains one of the most important unanswered questions in climate dynamics, according to Matt Huber, a professor in Purdue University’s Department of Earth and Atmospheric Sciences. The Pliocene was a warmer time than now with high carbon dioxide levels. The present study found that hurricanes influenced by weakened atmospheric circulation — possibly related to high levels of carbon dioxide — contributed to very warm temperatures in the Pacific Ocean, which in turn led to more frequent and intense hurricanes. The research indicates that Earth’s climate may have multiple states based on this feedback cycle, meaning that the climate could change qualitatively in response to the effects of global warming.

Opposition Republicans are using the delaying tactic at a record-setting pace. "The numbers are astonishing in this Congress," says Jim Riddlesperger, political science professor at Texas Christian University in Fort Worth. The filibuster, using seemingly endless debate to block legislative action, has become entrenched like a dandelion tap root in the midst of the shrill partisanship gripping Washington. But the filibuster is nothing new. Its use dates to the mists of Senate history, but until the civil rights era, it was rarely used.

As a matter of political philosophy, the concept of the filibuster arises from a deep-seated, historic concern among Americans that the minority not be steamrolled by the majority. It is a brake and protective device rooted in the same U.S. political sensibility that gave each state two senators regardless of population. The same impulse gave Americans the Electoral College in presidential contests — a structure from earliest U.S. history designed to give smaller population states greater influence in choosing the nation's leader. Given recent use of the filibuster by minority Republicans and the party's success in snarling the legislative process in this Congress, Democrats say the minority has gone way beyond just protecting its interests. The frequency of filibusters — plus threats to use them — are measured by the number of times the upper chamber votes on cloture. Such votes test the majority's ability to hold together 60 members to break a filibuster. In the 110th Congress of 2007-2008, with Republicans in the minority, there were a record 112 cloture votes. In the current session of Congress — the 111th — for all of 2009 and the first two months of 2010 the number already exceeds 40. The most the filibuster has been used when Democrats were in the minority was 58 times in the 106th Congress of 1999-2000.
