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.

University of Edinburgh law lecturer Andres Guadamuz wrote a blog entry this week highlighting some particularly troubling aspects of the IIPA's 301 recommendations. The organization has condemned Indonesia and several other countries for encouraging government adoption of open source software. According to the IIPA, official government endorsements of open source software create "trade barriers" and restrict "equitable market access" for software companies. The profound absurdity of this accusation is exacerbated by the fact that Indonesia's move towards open source software was almost entirely motivated by a desire to eliminate the use of pirated software within the government IT infrastructure. It's important to understand that Indonesia has not mandated the adoption of open source software or barred government agencies from purchasing proprietary commercial software. The Indonesian government issued a statement in 2009 informing municipal governments that they had to stop using pirated software. The statement said that government agencies must either purchase legally licensed commercial software or switch to free and open source alternatives in order to comply with copyright law. This attempt by Indonesia to promote legal software procurement processes by endorsing the viability of open source software has apparently angered the IIPA. In its 301 recommendations for Indonesia, the IIPA demands that the government rescind its 2009 statement. According to the IIPA, Indonesia's policy "weakens the software industry and undermines its long-term competitiveness" because open source software "encourages a mindset that does not give due consideration to the value to intellectual creations [and] fails to build respect for intellectual property rights." The number of ways in which the IIPA's statements regarding open source software are egregiously misleading and dishonest are too numerous to count. The IIPA seems to have completely missed the fact that there is a very robust ecosystem of commercial software vendors in the open source software market and that open source software is at the heart of some of the most popular consumer electronics products that are sold in the United States. It has clearly become an important part of the US software economy and increasingly serves as an enabler of innovation and technological progress. In light of the profitability of Red Hat and other open source leaders, it seems absurd to contend that open source software adoption will weaken the software industry or reduce its competitiveness. In fact, the emergence of open source software has contributed to creating a more competitive landscape in the software industry by offering alternative business models that enable smaller companies to gain traction against the dominant incumbent players. The IIPA's position is profoundly hypocritical, because many parts of the US government, including the Department of Defense, have issued their own memos endorsing open source software adoption. The IIPA's disingenuous move to equate open source software with piracy reeks of desperation. The BSA and other IIPA members are likely losing sleep over open source software because that development model and approach to licensing will empower developing countries to build their own domestic IT industries, eliminating the need for them to tithe to American software giants. It's another failing of the 301 review, which Big Content wants used to coerce other countries into adopting ever-more-stringent copyright laws.

Reconciliation was created through the Budget Reform Act of 1974 in an effort to streamline the budget process, strengthen the ability of Congress to make tough decisions regarding deficits, and to make legislative decision-making more efficient. Congress quickly expanded on the types of measures that could be considered under reconciliation until 1985 and 1986, when the Senate passed rules proposed by Sen. Robert Byrd that limited what could or could not be included when using this process. Before moving forward, Democrats must consider two questions. The first is whether using reconciliation to pass health care is legitimate or an abuse of the process. Republicans have charged that this would be akin to forcing the program through the chamber rather than passing the bill through negotiation and compromise. On this question, the answer is easy. Reconciliation has been as much a part of the Senate in the past three decades as the filibuster. According to an article that was published in The New Republic, Congress passed 22 reconciliation bills between 1980 and 2008. Many important policy changes were enacted through this process, including the Children's Health Insurance Program, COBRA (which allows people who switch jobs to keep their health care), student aid reform, expansions in Medicaid and several major tax cuts. NPR's Julie Rovner reported that most of the health care reforms enacted in the past two decades have gone through reconciliation. President Ronald Reagan was one of the first presidents to make aggressive use of reconciliation when he pushed through his economic program in 1981. Senate Majority Leader Howard Baker said then that speed had been essential because "Every day that this is delayed makes it more difficult to pass. This is an extraordinary proposal, and these are extraordinary times." Presidents Jimmy Carter, George H.W. Bush, Bill Clinton and George W. Bush all used reconciliation as well. It is worth noting that these presidents, particularly George W. Bush, also made use of sweeping executive power to circumvent Congress altogether. The second question is more difficult and it involves perceptions. If the Democratic leadership wants to use this tactic, they have to convince enough members of their own party that this won't scare off independent voters. This argument was harder to make in 2009 than in 2010. But after a year of dealing with paralysis in the Senate and highly effective Republican obstruction, more Democrats are coming on board. The leadership must be proactive in responding to the criticism about reconciliation. They will have to explain that reconciliation is a legitimate process by pointing to the history. They will also have to connect the dots for voters frustrated with the ineffective government by explaining that the constant use of the filibuster has turned the Senate into a supermajority institution where both parties have found it extraordinarily difficult -- virtually impossible -- to pass major legislation.On this point, Republicans and Democrats actually agree. Indeed, as Democrats make this decision, Kentucky Republican Senator Jim Bunning is objecting to a unanimous consent order and single-handedly preventing the Senate from passing an important bill to assist unemployed workers.

Today, he is emerging as one of the nation’s archreformers, pushing to impose some of the most stringent new financial regulations in history. And as the head of the Commodity Futures Trading Commission, the leading contender to oversee the complex derivatives contracts that played a central role in the financial crisis and, in turn, the Great Recession, he is in a position to influence the outcome. It may seem an unlikely conversion, but it is one that has won the approval of Brooksley E. Born, of all people, a former outspoken head of the commission. She sounded alarms more than a decade ago about the dangers hiding in the poorly understood derivatives market and was silenced by the same Washington power brokers that counted Mr. Gensler as a member. Mr. Gensler opposed Ms. Born, according to people who worked at the commission in the 1990s, and in 2000 played a significant role in shepherding through Congress deregulation measures that led to explosive growth of the over-the-counter derivatives market. That was then. These days, Ms. Born is convinced of Mr. Gensler’s reformist zeal, as he takes on Wall Street in what is becoming one of the fiercest battles over regulation in the postcrisis era. “I think he is doing very well,” she said in an interview. “He certainly seems to be committed to robust oversight of derivatives and limiting excessive speculation and leverage.” The proposals championed by Mr. Gensler, if adopted by Congress, would substantially alter what is now a largely unregulated market in over-the-counter derivatives, financial instruments used by companies and investors to protect themselves and bet on moves in variables, like interest rates or currencies, and to speculate. The proposals include forcing the big banks that sell derivatives to conduct their trades in the open on public exchanges and clear them through central clearinghouses, so that any investor can see the prices that dealers charge their customers. Today, those transactions are bilateral and private.

In 1982, the top 1 percent of pop stars, in terms of pay, raked in 26 percent of concert ticket revenue. In 2003, that top percentage of stars — names like Justin Timberlake, Christina Aguilera or 50 Cent — was taking 56 percent of the concert pie.

. In an article entitled “The Economics of Superstars,” he argued that technological changes would allow the best performers in a given field to serve a bigger market and thus reap a greater share of its revenue. But this would also reduce the spoils available to the less gifted in the business.

IF one loosens slightly the role played by technological progress, Dr. Rosen’s framework also does a pretty good job explaining the evolution of executive pay. In 1977, an elite chief executive working at one of America’s top 100 companies earned about 50 times the wage of its average worker. Three decades later, the nation’s best-paid C.E.O.’s made about 1,100 times the pay of a worker on the production line.
