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.

The Pliocene epoch is the period in the geologic timescale that extends from 5 million to 3 million years before present. Although scientists know that the early Pliocene had carbon dioxide concentrations similar to those of today, it has remained a mystery what caused the high levels of greenhouse gas and how the Pliocene's warm conditions, including an extensive warm pool in the Pacific Ocean and temperatures that were roughly 4 degrees C higher than today's, were maintained. In a paper published February 25 in Nature, Kerry Emanuel and two colleagues from Yale University's Department of Geology and Geophysics suggest that a positive feedback between tropical cyclones - commonly called hurricanes and typhoons - and the circulation in the Pacific could have been the mechanism that enabled the Pliocene's warm climate.
Robert Reich (The Big Lie) - 0 views

Republicans are telling Americans a Big Lie, and Obama and the Democrats are letting them. The Big Lie is our economic problems are due to a government that's too large, and therefore the solution is to shrink it. The truth is our economic problems stem from the biggest concentration of income and wealth at the top since 1928, combined with stagnant incomes for most of the rest of us. The result: Americans no longer have the purchasing power to keep the economy going at full capacity. Since the debt bubble burst, most Americans have had to reduce their spending; they need to repay their debts, can't borrow as before, and must save for retirement.
Who Rules America: Wealth, Income, and Power - 0 views

This document presents details on the wealth and income distributions in the United States, and explains how we use these two distributions as power indicators. Some of the information may come as a surprise to many people. In fact, I know it will be a surprise and then some, because of a recent study (Norton & Ariely, 2010) showing that most Americans (high income or low income, female or male, young or old, Republican or Democrat) have no idea just how concentrated the wealth distribution actually is. More on that a bit later.
Technology: Necessary but Insufficient for Human Survival | Thinkahol's Blog - 0 views

In the context of technology the only way out is through. Global society is dependent on artificially inflated energy resources-i.e. oil-that are directly leading us toward total collapse. Technology is being used to most efficiently maximize wealth of the largest corporate conglomerates at the expense of the social fabric and a living environment. The biosphere is in fact collapsing. The technology exists to solve our technical problems but the solutions do not seem like they will be effectively put to use. The power structures concentrating money off the status quo are too entrenched. Each human is called on to become more aware.
The Blog : How Rich is Too Rich? : Sam Harris - 0 views

I've written before about the crisis of inequality in the United States and about the quasi-religious abhorrence of "wealth redistribution" that causes many Americans to oppose tax increases, even on the ultra rich. The conviction that taxation is intrinsically evil has achieved a sadomasochistic fervor in conservative circles-producing the Tea Party, their Republican zombies, and increasingly terrifying failures of governance. Happily, not all billionaires are content to hoard their money in silence. Earlier this week, Warren Buffett published an op-ed in the New York Times in which he criticized our current approach to raising revenue. As he has lamented many times before, he is taxed at a lower rate than his secretary is. Many conservatives pretend not to find this embarrassing. Conservatives view taxation as a species of theft-and to raise taxes, on anyone for any reason, is simply to steal more. Conservatives also believe that people become rich by creating value for others. Once rich, they cannot help but create more value by investing their wealth and spawning new jobs in the process. We should not punish our best and brightest for their success, and stealing their money is a form of punishment. Of course, this is just an economic cartoon. We don't have perfectly efficient markets, and many wealthy people don't create much in the way of value for others. In fact, as our recent financial crisis has shown, it is possible for a few people to become extraordinarily rich by wrecking the global economy. Nevertheless, the basic argument often holds: Many people have amassed fortunes because they (or their parent's, parent's, parents) created value. Steve Jobs resurrected Apple Computer and has since produced one gorgeous product after another. It isn't an accident that millions of us are happy to give him our money. But even in the ideal case, where obvious value has been created, how much wealth can one person be allowed to keep? A trillion doll
Sounds of Resistance are Growing Join Americans Fed Up With Big Finance Americans Acr... - 0 views

Are you tired of big banks making record profits, paying giant executive salaries and bonuses and then cooking the books so they avoid paying taxes? We are. And, we are responding. Join us.On April 15 in Union Square Park in New York City at 11:00 AM we are holding a "Sounds of Resistance Concert" and protest against the big corporate banks that have undermined the U.S. economy and displaced families from their homes. Big Finance has taken more than a trillion from the Department of Treasury and Federal Reserve to pay for their casino gambling on Wall Street but they are still forcing people out of their homes, not lending to small businesses and choking the economy.The concert will feature political hip-hop/rock powerhouse Junkyard Empire with special guests Broadcast Live and Sketch the Cataclysm. Chris Hedges will speak about the growing culture of resistance. Other performers and speakers are invited.The protest will include a picket of the Union Square Bank of America - a major culprit in the great rip off of the American taxpayer.This concert and protest are part of the effort to build the urgently needed movement to shift power to the people and away from concentrated capital interests.

Americans have been watching protests against oppressive regimes that concentrate massive wealth in the hands of an elite few. Yet in our own democracy, 1 percent of the people take nearly a quarter of the nation's income-an inequality even the wealthy will come to regret.

What could start a popular resurgence in this country against the abuses of concentrated, avaricious corporatism? Imagine the arrogance of passing on to already cheated working people and the jobless enormous corporate losses? This is achieved through government bailouts and tax escapes.
Stonewall riots - Wikipedia, the free encyclopedia - 0 views

They are frequently cited as the first instance in American history when people in the homosexual community fought back against a government-sponsored system that persecuted sexual minorities, and they have become the defining event that marked the start of the gay rights movement in the United States and around the world. American gays and lesbians in the 1950s and 1960s faced a legal system more anti-homosexual than those of some Warsaw Pact countries.[note 1][2] Early homophile groups in the U.S. sought to prove that gay people could be assimilated into society, and they favored non-confrontational education for homosexuals and heterosexuals alike. The last years of the 1960s, however, were very contentious, as many social movements were active, including the African American Civil Rights Movement, the Counterculture of the 1960s, and antiwar demonstrations. These influences, along with the liberal environment of Greenwich Village, served as catalysts for the Stonewall riots. Very few establishments welcomed openly gay people in the 1950s and 1960s. Those that did were often bars, although bar owners and managers were rarely gay. The Stonewall Inn, at the time, was owned by the Mafia.[3][4] It catered to an assortment of patrons, but it was known to be popular with the poorest and most marginalized people in the gay community: drag queens, representatives of a newly self-aware transgender community, effeminate young men, hustlers, and homeless youth. Police raids on gay bars were routine in the 1960s, but officers quickly lost control of the situation at the Stonewall Inn, and attracted a crowd that was incited to riot. Tensions between New York City police and gay residents of Greenwich Village erupted into more protests the next evening, and again several nights later. Within weeks, Village residents quickly organized into activist groups to concentrate efforts on establishing places for gays and lesbians to be open about their sexual orientation without fear o
Capitalism's Self-inflicted Apocalypse - 0 views

The present economic crisis, however, has convinced even some prominent free-marketeers that something is gravely amiss. Truth be told, capitalism has yet to come to terms with several historical forces that cause it endless trouble: democracy, prosperity, and capitalism itself, the very entities that capitalist rulers claim to be fostering.

Some eighty years ago Supreme Court Justice Louis Brandeis commented, “We can have democracy in this country, or we can have great wealth concentrated in the hands of a few, but we can’t have both.” Moneyed interests have been opponents not proponents of democracy.

In the early days of the Republic the rich and well-born imposed property qualifications for voting and officeholding. They opposed the direct election of candidates (note, their Electoral College is still with us). And for decades they resisted extending the franchise to less favored groups such as propertyless working men, immigrants, racial minorities, and women.
