Pliocene hurricanes CO2 feeback

  • 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.

Artic life ocean climate change effects

    More than 6,000 different species living on the sea-floor have been identified so far and more than half of these are unique to the icy continent. A combination of long-term monitoring studies, newly gathered information on the marine life distribution and global ocean warming models, enable the scientists to identify Antarctica's marine "biodiversity hotspots". Researcher Griffiths describes how krill populations (the shrimp-like invertebrates eaten by penguins, whales and seals) are reducing as a result of a decrease in sea-ice cover. A much smaller crustacean (copepods) is dominating the area once occupied by them. This shifts the balance of the food web to favour predators, like jellyfish, that are not eaten by penguins and other Southern Ocean higher predators. Sea-ice reduction is also affecting penguins that breed on the ice.

Klamath River dams agreement negotiation controversy protest violence

shared by Skeptical Debunker on 03 Mar 10 - Cached
  • For most of the last 1,500 years, the river supported a sustainable salmon economy. Salmon were at the heart of all the Klamath’s tribal cultures, and Indians were careful not to over-harvest them. Each summer, the lower Klamath’s Yurok and Hoopa tribes blocked the upstream paths of spawning salmon with barriers; then, after ten days of fishing, they removed the barriers, allowing upstream tribes to take their share. As the salmon completed their lifecycle, dying in the waters where they’d been spawned, they enriched the watershed with nutrients ingested during years in the ocean. Among the beneficiaries were at least 22 species of mammals and birds that eat salmon. Even the salmon carcasses that bears left behind on the riverbanks fertilized trees that provided shade along the river’s banks, cooling its waters so that the next generation of vulnerable juvenile salmon could survive. “We tried to go to court, to go through the political process, but it didn’t work. …The big issues were still out there, and we still had to resolve them.” Salmon’s biological family may have started in the age of dinosaurs a hundred million years ago. They’ve survived through heat waves and droughts, in rivers of varying flow, temperature, and nutrient load – but they were as ill-prepared for Europeans’ arrival as the Indians themselves. Gold miners who showed up in the mid-nineteenth century washed entire hillsides into the river with high-pressure hoses and scoured the river’s bed with dredges. Loggers dragged trees down streambeds, causing massive erosion, and dumped sawdust into the river, smothering incubating salmon eggs. Cattle grazed at the river’s edge, causing soil erosion and destroying shade-giving vegetation. Farmers diverted water to feed their crops. The dams were the crowning blows. Between 1908 and 1962, six dams were built on the Klamath. The tallest, the 173-foot-high Iron Gate, is the farthest downstream, and definitively blocked salmon from the river’s upper quarter – after it was built, the river’s salmon population plummeted. In addition, the dams devastated water quality by promoting thick growths of toxic algae in the reservoirs. For Klamath basin farmers, however, the dams were deemed indispensable, as they generated hydropower that made pumping of their irrigation water possible.To the farmers, the potential loss of the dams’ hydropower was considered no less crippling than an end to Klamath-supplied irrigation.
  • For most of the last century, the farmers were oblivious to the damage that dams and water diversions caused downstream, while the tribes and commercial fishermen quietly seethed. The annual salmon run, once so abundant that people caught fish with their hands, was roughly pegged at more than a million fish at its peak; in recent years it has dropped to perhaps 200,000 in good years, and as low as 12,000 – below the minimum believed necessary to sustain the runs – in bad years. Spring Chinook, which once comprised the river’s dominant salmon run, entirely disappeared. Two fish species – the Lost River sucker and the shortnose sucker – that once supported a commercial fishery, were listed as endangered in 1988. Coho salmon were listed as threatened nine years later. All this has had a devastating impact on the tribes. Traditionally able to sustain themselves throughout the year on seasonal migrations of the river’s salmon, trout, and candlefish, tribal members suffered greatly as the runs declined or went extinct. For four decades beginning in 1933, the tribes were barred from fishing the river even as commercial fishermen went unrestricted. Members of the Karuk tribe once consumed an estimated average of 450 pounds of salmon a year; a 2004 survey found that the average had dropped to five pounds a year. The survey linked salmon’s absence to epidemics of diabetes and heart disease that now plague the Karuk. The 2001 cutoff left farmers without irrigated water for the first time in the Klamath Project’s history. Over the next four months, many farmers performed repeated acts of civil disobedience, most notably when a bucket brigade passed pails of banned water from its lake storage to an irrigation canal while thousands of onlookers cheered. The protests attracted Christian-fundamentalist, anti-government, and property rights advocates from throughout the West; former Idaho Congresswoman Helen Chenoweth-Hage likened the farmers’ struggle to the American Revolution.

  • A year later, it was the tribes’ and fishermen’s turn to experience calamity. According to a Washington Post report, Vice President Dick Cheney ordered Interior Department officials to deliver Klamath water to Project farmers in 2002, even though federal law seemed to favor the fish. Interior Secretary Gale Norton herself opened the head gates launching the 2002 release of water to the Project, while approving farmers chanted, “Let the water flow!” Six months later, the carcasses of tens of thousands of Chinook and Coho salmon washed up on the riverbanks near the Klamath’s mouth, in what is considered the largest adult salmon die-off in the history of the American West. The immediate cause was a parasitic disease called ich, or “white spot disease,” commonly triggered when fish are overcrowded. Given the presence of an unusually large fall Chinook run in 2002 and a paucity of Klamath flow, the 2002 water diversion probably caused the die-off. Yurok representatives said that months earlier they begged government officials to release more water into the lower river to support the salmon, but were ignored. photo courtesy Earthjustice In 2002, low water levels on the Klamath led to the largest adult salmon die-off in the history of the American West. The die-off deprived many tribes-people of salmon and abruptly ended the river’s sport-fishing season, but its impact didn’t fully register until four years later, when the offspring of the prematurely deceased 2002 salmon would have made their spawning run. By then the Klamath stock was so depleted that the federal government placed 700 miles of Pacific Ocean coastline, from San Francisco to central Oregon, off limits to commercial salmon fishing for most of the 2006 fishing season. As a result, commercial ocean fishermen lost about $100 million in income, forcing many into bankruptcy. Even more devastating, a precipitous decline in Sacramento River salmon led to the cancellation of the entire Pacific salmon fishing season in both 2008 and 2009. The Klamath basin was in a permanent crisis. It turned out that desperation and frustration were perfect preconditions for negotiations. “Every one of us would have rolled the others if we could have,” Fletcher, the Yurok leader, says. “We all tried to go to court, to go through the political process, but it didn’t work – we might win one battle today and lose one tomorrow, so nothing was resolved. We spent millions of dollars on attorneys, plane tickets to Washington, political donations, but it didn’t make any of us sleep any better, because the big issues were still out there, and we still had to resolve them.”
  • In January 2008, the negotiators announced the first of two breakthrough Klamath pacts: the 255-page Klamath Basin Restoration Agreement. In it, most of the parties – farmers, three of the four tribes, a commercial fishermen’s group, seven federal and state agencies, and nine environmental groups – agreed to a basic plan. It includes measures to take down the four dams, divert some water from Project farmers to the river in return for guaranteeing the farmers’ right to a smaller amount, restore fisheries habitat, reintroduce salmon to the upper basin, develop renewable energy to make up for the loss of the dams, and support the Klamath Tribes of Oregon’s effort to regain some land lost when Congress “terminated” its reservation in 1962. This was a seminal moment, a genuine reconciliation among tribal and agricultural leaders who discovered that the hatred they’d nursed was unfounded. “Trust is the key,” says Kandra, the Project farmer who went from litigant to negotiator. “We took little baby steps, giving each other opportunities to build trust, and then we got to a place where we could have some really candid discussions, without screaming and yelling – it was like, ‘Here’s how I see the world.’ Pretty valuable stuff. The folks that developed those kinds of relationships got along pretty good.” Still, one crucial ingredient was missing: Unless PacifiCorp agreed to dismantle the dams, river restoration was impossible, and the pact was a well-intentioned, empty exercise. But PacifiCorp now had compelling reasons to consider dam removal. Not only was relicensing going to be expensive, but Klamath tribespeople were becoming an embarrassing irritant, in two consecutive years interrupting Berkshire Hathaway’s annual-meeting/Buffett-lovefests in Omaha with nonviolent protests that won media attention. Also, the Bush administration, customarily no friend of dam removal, signaled its support for a basin-wide agreement. Negotiations between PacifiCorp and mid-level government officials began in January 2008, but made little progress until a meeting in Shepherdstown, West Virginia four months later, when for the first time Senior Interior Department Counselor Michael Bogert presided. As Bogert recently explained, President Bush himself took an interest in the Klamath “because it was early on in his watch that the Klamath became almost a symbol” of river basin dysfunction. To Bush, the decision to support dam removal was a business decision, not an environmental one: The “game-changer,” Bogert said, was the realization that because of the high cost of relicensing, dam removal made good fiscal sense for PacifiCorp. That fact distinguished the Klamath from other dam removal controversies such as the battle over four dams on Idaho’s Snake River, whose removal the Bush administration continued to oppose.
  • In November 2008, when then-Interior Secretary Dirk Kempthorne announced a detailed agreement in principle with PacifiCorp to take down the dams, he acknowledged that he customarily opposed dam removal, but that the Klamath had taught him “to evaluate each situation on a case-by-case basis.” In September 2009, Kempthorne’s successor, Ken Salazar, announced that PacifiCorp and government officials had reached a final agreement. PacifiCorp and the many signers of the earlier Klamath Basin Restoration Agreement then ironed out inconsistencies between the two pacts in a final negotiation that ended with a final deal in January 2010.

    Maybe the Klamath River basin would have turned itself around without Jeff Mitchell. Back in 2001, at the pinnacle of the conflict over the river's fate, when the Klamath earned its reputation as the most contentious river basin in the country, Mitchell planted a seed. Thanks to a drought and a resulting Interior Department decision to protect the river's endangered fish stocks, delivery of Klamath water to California and Oregon farmers was cut off mid-season, and they were livid. They blamed the Endangered Species Act, the federal government that enforced it, and the basin's salmon-centric Indians who considered irrigation a death sentence for their cultures. The basin divided up, farmers and ranchers on one side, Indians and commercial fishermen on the other. They sued one another, denounced one another in the press, and hired lobbyists to pass legislation undermining one another. Drunken goose-hunters discharged shotguns over the heads of Indians and shot up storefronts in the largely tribal town of Chiloquin, Oregon. An alcohol-fueled argument over water there prompted a white boy to kick in the head of a young Indian, killing him.

    "In 2009, the scientific literature caught up with what top climate scientists have been saying privately for a few years now: * Many of the predicted impacts of human-caused climate change are occurring much faster than anybody expected - particularly ice melt, everywhere you look on the planet. * If we stay anywhere near our current emissions path, we are facing incalculable catastrophes by century's end, including rapid sea level rise, massive wildfires, widespread Dust-Bowlification, large oceanic dead zones, and 9°F warming - much of which could be all but irreversible for centuries. And that's not the worst-case scenario! * The consequences for human health and well being would be extreme. That's no surprise to anybody who has talked to leading climate scientists in recent years, read my book Hell and High Water (or a number of other books), or followed this blog. Still, it is a scientific reality that I don't think more than 2 people in 100 fully grasp, so I'm going to review here the past year in climate science. I'll focus primarily on the peer-reviewed literature, but also look at some major summary reports."

It was the top 1% of the country who did this. THEY brought on the mortgage crisis. THEY made off with billions of dollars from our economy. THEY have systematically destroyed the middle class.

They've removed it from circulation and left us begging for school supplies and fire trucks and libraries. Even the Wall Street Journal admits that the uber-rich are currently just sitting on almost $2 trillion of cash. They're not creating jobs with it. They're not re-circulating it. They're just hanging on to it hoping to make more money off it by continuing their casino games in the stock market, the derivatives market, the credit default swaps market and any other crazy scheme they can invent.

  • THE 2007 STATEMENT from the United Nation’s climate panel, the IPCC, that the average temperature on earth must not rise more than two degrees Celsius (3.6 degrees Fahrenheit) over pre-industrial levels or an incalculable disaster will take place, was a powerful reminder of the nature of the problem.
  • The main reason is that as the oceans warm up they lose the ability to absorb carbon dioxide. Another horrific truth is that there is more carbon beneath the permafrost of the polar regions than in the entire atmosphere. Experts say that if the emissions of carbon dioxide, sulphate and nitrogen dioxide continue as they are today, this bomb will explode within the next 100 years.
  • Does this mean that emissions are dropping? Not at all. So what does this trade mean in practice? An Oxford academic who studied the scheme, Adam Bumpus, concluded that "this regulation is ultimately there to facilitate the markets – it’s not about making cheap reductions, it’s about making a lot of money"
  • ...6 more annotations...
  • Therefore, so the theory goes, the buyer pays to emit greenhouse gases while the seller is rewarded for having reduced emissions by more than their quota. There is only one problem. It does not work like that.
  • The market always chooses the easiest means to save a given quantity of carbon in the short term, regardless of what action is needed for long-term reduction. The result is that the system reinforces technological lock-in. For instance, small cuts may often be achieved cheaply through making a technology a little bit more efficient, whereas larger cuts would require massive investments in new technology.
  • The problem with most of the established green organisations is that they seek mechanisms, such as emissions markets, green taxes, green laws or other technical fixes to the problem of polluting fat cats.
  • The carbon trade system is bad in itself. But the fact that governments or other capitalist controlled bodies allocated the emissions permits in the first place, the logic of the market meant that they handed out too many permits out of fear of being in a disadvantage with competing capitalist powers. Today, there are more permits in circulation than there is capacity to pump out greenhouse gases!
  • MANY CDMS ARE about dams. The push for mega-dams has been justified by both development banks and multinationals as being necessary for the development of Africa and to combat carbon emissions. While governments, such as the US, Britain and China, announce mighty plans to electrify Africa, and other ‘aid’ schemes, the companies set in action the Boot model – Build, Own, Operate and Transfer – emptying the rivers of Africa to feed the growing energy needs of Europe, etc. And it is a very lucrative business when they can earn more carbon emission credits in the process. Large dams provide electricity for multinational companies, water for mining, and irrigation for large-scale foreign-owned farms.
  • In a study of 50 dams in Africa, professor Thayer Scudder, formerly the leading resettlement consultant for the World Bank, found that landlessness affected 86% and joblessness 80% of the displaced people. Lack of food security impacted on 79% of the people displaced by these ‘green dams’.
