Giant Underwater Plume Confirmed—Gulf Oil Not Degrading

Christine Dell'Amore
Published August 19, 2010
A giant plume from BP's Gulf of Mexico oil spill has been confirmed deep in the ocean—and there are signs that it may stick around, a new study says.
Many scientists had predicted that oil-eating bacteria—already common in the Gulf due to natural oil seeps—would process much of the crude leaked fromBP's Deepwater Horizon wellhead, which was capped July 15. (Read more about how nature is fighting the oil spill.)
But new evidence shows that a 22-mile-long (35-kilometer-long), 650-foot-high (200-meter-high) pocket of oil has persisted for months at depths of 3,600 feet (1,100 meters), according to a team from Woods Hole Oceanographic Institution (WHOI) in Massachusetts.
The oil plume's stability is "a little unexpected," study leader Richard Camilli, of WHOI's Applied Ocean Physics and Engineering Department, said at a Thursday press briefing in Washington, D.C.
"We don't have any clear indication as to why it set up at that depth."
It's unclear why the Gulf's microbes aren't eating the oil plume, but the organisms are infamous for being unpredictable, said study co-authorChristopher Reddy, a marine chemist at WHOI.
Counting on microbes to quickly clean up an oil spill is "like asking a teenager to do a chore. You tell them to do it on a Friday, to do it when it's most advantageous, and they do it on a Saturday," Reddy told National Geographic News earlier this month.
Further studies are needed to figure out why the plume isn't degrading, Reddy said during the press briefing: "We don't live in the world of the TV show CSI. ... Patience is a virtue."
Hard Evidence for Gulf Oil Plume
During a ten-day research cruise in June, the WHOI team used autonomous underwater vehicles (AUVs), free-swimming probes that are the "next generation" of remotely operated vehicles, Camilli said during the briefing.
The team's AUVs were equipped with mass spectrometers—devices that measure the masses of molecules. The spectrometers collected thousands of samples in various regions near the spill site.
Most of these samples detected hydrocarbons—ingredients of oil—at concentrations of 50 micrograms a liter.
Using this data, the scientists were able to piece together the shapes and sizes of two oil plumes: the large, deep plume and a more diffuse plume spread out between depths of 160 and 1,600 feet (50 and 500 meters).
University of South Florida (USF) chemical oceanographer David Hollander said the discovery of stubborn oil in the deep sea "falls right into line" with his recent findings.
"These hydrocarbons are plentiful, and will be around for a long time," Hollander said by email.
Hollander and a USF team announced this week that oil may have been found deep on the Gulf seafloor, and that it appears to be toxic to phytoplankton, small plants that live in the deep ocean and make up the base of the marine food chain.
It's too early to say whether the plume is harmful to marine life in the area studied by WHOI, expedition member Reddy said.
But the research does show that the oil plume hasn't yet spurred oxygen depletion in the Gulf, which can create a dead zone—a swath of ocean largely devoid of life-forms—according to Ruoying He, a physical oceanographer at North Carolina State University in Raleigh, who was not involved in the new research.
He added that the new study—published today in the journal Science—is "extremely important," in part because it offers hard evidence of the suspected oil plume in the Gulf.
"I'm happy to see some in situ observations published so quickly," he said.
How Far Will Gulf Oil Plume Go?
The study raises another fundamental question that North Carolina's He is currently modeling: How far will the Gulf oil spill travel?
The plume has already fanned out a considerable distance from the BP wellhead, He noted. At the time of the survey, the plume was migrating about 4 miles (6.5 kilometers) a day southwest from the spill site, according to the study.
And with oil-eating bacteria taking their time, it's possible that the oil could be transported even farther from the well before the crude gets degraded, WHOI's Camilli said.
It's also possible the oil plume is already gone: "We don't know what the fate of this plume now is—this was a forensic snapshot in late June, and we have not been back there since," Camilli cautioned.
Deep-Ocean Focus Needed for Oil Cleanups
Since the toxic effects of oil and chemical dispersants are not fully known, "there is great room for debate and contrasting interpretation as to what the impacts will be," Robert Carney, a biological oceanographer at Louisiana State University (LSU) in Baton Rouge, said by email.
At this point, though, a "far more valuable undertaking" would be to start figuring out how to prevent doing further harm to the deep ocean, he said.
"Through this all we have witnessed an aged and untested bit of dogma dominate response decisions: Protect the beach," Carney said. (See: "Oil Found in Gulf Beach Sand, Even After Cleanups.")
"Quite obviously, it is the whole ocean that we must protect and effectively manage," he said. "We are badly in need of new ideas."

"Firecane" Myth Busted—No Danger on Katrina Anniversary

                                                               Brian Handwerk
                                                              for National Geographic News
                                              Published August 25, 2010
With the Gulf oil spill largely gone, at least at the surface, you can rest easy that the fifth anniversary of Hurricane Katrina's Gulf Coast landfall won't be marked with a "firecane" or "black rain"—and it never would have been.
Flaming hurricanes and flammable rain are scientifically impossible, according to myth-busting scientists.
Ignited online, the firecane rumor has been covered by publications includingNew York magazine (read "Firecane!") and debated on Web forums such asMyth-Weavers, where one participant summed up how firecanes might be born:
Hurricane
Hurricane sucks up oil
Lightning ignites oil
FIRECANE!
But—surprise—the scenario doesn't stand up to scrutiny, according to Jeff Masters, director of meteorology for the Weather Underground website.
In an oil spill, Masters explained, it's the vapors from volatile compounds that burn, not the liquid oil itself. And most of those flammable volatiles evaporate and disperse soon after oil enters the water.
Even at the oil slick's worst this summer, the oil at the surface of the Gulf of Mexico (map) was largely a type of thick crude loaded with "heavy compounds" called asphaltenes, which don't burn easily under any conditions, Masters said.
This summer, for example, BP had a hard time starting even the intentional burns meant to deplete the slick, according to environmental chemist Barry Dellinger. In a marine oil spill, he added, there's simply too much water mixed with the crude to allow for a sustained blaze.
"They actually use napalm to start the burns, or they can't get enough heat," said Dellinger, of Louisiana State University.
Unlike napalm, the slow-burning fuel made infamous in the Vietnam War, "lightning would be a quick strike," he said.
"I wouldn't think that you could have enough sustained heat from that to continue to have oil vaporize and burn."
Even if lightning could somehow ignite a hypothetical oily storm, the fire would quickly be quenched, according to Weather Underground's Masters.
"Hurricane winds and rain chop up the water so much," Masters said. "It would be very hard to sustain a fire in those kinds of conditions."
And that's assuming the oil could make it into hurricane winds and clouds in the first place.
Black Rain?
If oil from an ocean spill were to impregnate storm clouds, you might theoretically end up with oily rain turning Gulf cities into tinderboxes. Just this June unsubstantiated videos purported to show "black rain" (for example,"Raining Oil in Louisiana?" on the Huffington Post).
But because seawater must evaporate to reach clouds and possibly turn to rain—and because the floating crude in an oil spill is as hard to evaporate as it is to burn—black rain is pure science fiction.
If a hurricane strikes an oil slick, "the amount of oil that's going to be able to evaporate is very, very tiny," said Chris Landsea, science and operations officer at the National Hurricane Center in Miami.
"So any concentration of oil in the rain would be puny and the rain not much different at all from that found in a regular hurricane."
In addition, the seawater that makes it into clouds—even when an oil slick is present—is naturally clean, Weather Underground's Masters said.
The very process of evaporation filters out impurities, which is why it's used to make distilled water, he noted. "So that's not a good way to get oil into rain."
Oil on Land, Minus the Pyrotechnics
There are ways for an ocean oil slick to end up on land—for example via storm surges, tornado-like waterspouts, and strong winds. (See pictures of oil and tarballs on Gulf beaches in May.)
None of those methods, though, promise fire in the sky or combustible rain.
"The idea of a firecane, or oil raining down from the sky," NOAA's Landsea said, "those are really just impossible scenarios."

Evils of False Progress Interfere in Fight for Climate - Now It's up to Us .



klamm.de - Geld. News. Promotion!

Although one yearns for global warming to indeed not exceed 2 degrees Celsius (or less, as African countries demand), the take-home message from the Copenhagen COP meeting is that polluters and growth mongers, large and small, will not let up. This is because they are not being forced to -- whether by their own peoples or by natural forces such as ecological or economic collapse. Most diabolical is the intention to switch energy as the main strategy for climate protection, when it will not work.

What has happened in Copenhagen -- is it really a matter of degree and the lack of strong measures? Or is it a matter of kind? Most technofixers are clever enough not to call for endless growth, but they may as well say there's unlimited, infinite growth through resource exploitation somehow made "green." Here's the revealing part of World Resources Institute's statement trumpeting the pathetically inadequate COP climate deal:

The political agreement struck today has immediate operational effect, including the mobilization of finance to build the clean energy economy in developing countries... The dealt "does provide the framework for countries to move forward with ambitious national action. Action that will build clean energy markets, create jobs, enhance energy security..."

These ideas are admissions of the determined business-as-usual reformist wing of the industrial elite to preserve, if they can, mass consumerism that feeds megaprofits.

Why should a few more months of negotiating do anything but buy some time for those who refuse to "get it"? Ongoing failure will continue to be dressed up as good-faith efforts within the vicissitudes of statecraft.

The real state of affairs is truly, "It's up to us." From personal lifestyle change that's openly shared and publicized, to concerted and individual direct action, to local initiatives toward weakening corporate power including via boycott, it's all up to us. Nations and global institutions have failed to honor life itself, and they're taking us down -- not unlike the uncounted species going extinct daily. It's hard to face our true challenge when it's easier to wait until the next election and pretend again that one is doing one's bit.

As long as any climate deal or eventual treaty is in reality a realignment of industrial investment, toward the renewable-energy Holy Grail regardless of oil reality, then the accepted story is a fraud:

"billions in financial commitments from rich countries to the developing world to help in the fight against climate change. It is hoped that all countries will agree to a control mechanism -- meaning that each country agrees to allow its progress toward emissions reduction targets to be internationally verified." [Spiegel, Dec. 18 -- 'The Search for a Deal']

This constitutes a fraud in terms of slashing emissions, when the "energy market" programs and budgets mainly exist for still more funding, as opposed to immediate action that the Earth's crisis demands.

Take the poor countries' situation: their main root problems include cash crops and associated damage, and infrastructure boondoggles that resulted in major debt and concessions to privatization. Meanwhile these societies' strengths -- local indigenous knowledge and strength of community in acceptance of nature -- are being eroded by the transnational corporations and their lackey international lenders and "developed"-nation governments.

Therefore, money for the "developing nations" is not the real answer. It would be nice if it happened, if it went for the right things such as environmental restoration (e.g., tree planting = jobs and food plus carbon sequestration). But the intended big money -- assuming it happens when redistribution of wealth normally doesn't come about without revolution -- will be wasted to a great extent on corruption, cronyism, and the belief in industrial progress. A modern myth is that energy technologies and fuels are all the same -- just "energy" -- and can be somehow maximized and interchanged for continued "growth." Not to completely dismiss energy-technology aid, the distribution of some community solar panels for shared refrigeration and shared computer access, for example, would be helpful. But an unprecedented mass movement to slash emissions is what has to happen.

Let's be real: "$100 billion (€69.5 billion) annually for developing countries by 2020" is just talk, and is not going to happen with any more certainty than the world's population can go up and up indefinitely. The global economy cannot be sustained, let alone grow, with the loss of cheaply extracted petroleum that has already hit. Crash has begun, including petrocollapse, and the great unravelling is in motion.

There's very little evidence that President Obama gets much of this. Post Carbon Institute's Asher Miller's statement on Obama's Copenhagen contribution says it well: "US President Barack Obama has chosen political expediency over truth and justice." One might go further and wonder why one should have expected much from someone who turned out to be another war-machine Uncle Tom.

It is appealing that Chancellor Merkel says ""We have to change our lifestyles," but does this mean what it should: sharing appliances, ceasing commutes, establishing local economics to the exclusion of corporatism? Or does she mean "greener cars" and flicking switches in every home that burn a different form of energy than at present?

Taking Responsibility for the Climate Crisis


The unnatural dominant culture, coldly spewing its noise and heat, subjecting us to dirty machines and pavement, no longer makes sense in terms of our needs as humans. But don't let it get you down and make you give up. Play your guitar, enjoy the company of friends, or whatever else restores your humanity. Perhaps the songs and the conversations will lead to some liberation and justice, alleviating the pain of this senseless system running our lives into the ground. But we must do even more. Finding a "better job" is no solution long-term, however much we think we need money to survive.

klamm.de - Geld. News. Promotion!

Taking responsibility for our own lot and the climate crisis means we must first reject an unworkable system and culture. I hasten to clarify; this does not mean there aren't a lot of nice people caught up in it. But if they believe elections and voting with their consumer dollars are going to save them from the ecological crisis and the slide into societal chaos of collapse, they are of no help to themselves or to the countless species being driven extinct by modern civilization.
In complaining about the failure of the Copenhagen COP 15 meeting, and continuing to beseech the Barack Obamas of the world to "please take good care of us," we are behaving like overgrown children who have no business coming back to helpless, hopeless parents to save us when we are reluctant to take matters into our own hands for our survival.

Except, the Obamas and Merkels and other corporate front men say to us, "Yes, there there, we're here for you. And we're trying to be green. Now be good and stay out of our way." So we go off and brood, get a bit more frustrated, and then we come back with more proposals, only to be disappointed -- as our graves are dug deeper by the technological war-for-profit growth- is-essential system. To legitimize a fixed game by continuing to play by its rules is foolish and tiresome to those of us who see though the sham and self-delusion.
Blaming the Copenhagen fiasco on... ?
Some activists, such as the "global web movement" Avaaz.org, blame "big polluters" such as the U.S. Chamber of Commerce for the U.S. stance on climate protection, while sparing Obama significant criticism. Avaaz probably did not read Naomi Klein's recent Guardian- UK article that made a good case for blaming Obama. The deeper problem is that many activists want to hope Obama is their guy, not the polluter's guy. Sure, sure.
Still another progressive environmentalist view finds Obama still heroic as a constrained realist facing a tough Congress: a Grist.org column stated, "Instead of directing our frustrations at Obama, let’s direct them at the paralysis of vision and understanding among the American people."
When we face the fact that we are on our own and must build an alternative society, it would seem wise to look at the only sustainable model humanity has known: indigenous, traditional society based on tribes. Except for a few experiments in civilization that eventually failed, such as the Mayans and the Mississippi culture, the cultures of revering nature and the universe as it is -- not as our technology could remake it -- succeeded for millennia.

Now we are up against the wall, trying to create ecovillages and implement permaculture before we are crushed. It's ironic that so few people see the need. This is one reason it is so hard to jump to a safe haven where these sound practices are followed. It takes a good deal of sacrifice or luck in being able to make major changes in one's life under the yoke of the vicious economic system. Even so, there's really nowhere to run to, when we're all in this together. But we can and should each improve our situations in a responsible way.
So keep your eyes peeled for opportunities to exit the corporate economy, or at least to become more self-sufficient while creating more community. Someday a tribe will form around you, or you'll have to go find one. Driving to the supermarket and shopping online, and in other fashions not working closely with family or neighbors, has no future. It is antisocial as well as ecocidal.

Looking for a Silver Lining in the Post-Summit Landscape

Much was left undone in Copenhagen, and the many loopholes in the climate accord could lead to rising emissions. But the conference averted disaster by keeping the UN climate negotiations alive, and some expressed hope that the growth of renewable energy technology may ultimately save the day.

Did British climate secretary Ed Miliband save the planet early on the final Saturday of the Copenhagen conference? It sounds like a risible claim, especially coming from a British journalist like myself. But hear me out.

klamm.de - Geld. News. Promotion!

At 7 a.m. on Saturday, with the conference 14 hours into overtime, the visibly exhausted and procedurally confused chairman of the summit, Danish Prime Minister Lars Lokke Rasmussen, cast a weary eye over the surviving delegates from an all-night session. After listening to more than 40 speeches from the floor and with dozens more delegates waiting to be heard, Rasmussen said there was no consensus on adopting the draft agreement produced by U.S. President Obama and 25 other heads of state the previous day. “Therefore I propose that we...” Almost certainly his next words would have been a recommendation to drop or delete the text.

The rejection of what was already known as the Copenhagen Accord would have been a catastrophic failure for both climate diplomacy and the climate. The United Nations process to fight climate change, set in train at the Earth Summit in Rio 17 years before, would have lain in tatters. The climate equivalent of the collapse of the world trade talks — the “Doha-isation of climate,” as one journalist quipped — would have reverberated for years, unleashing accelerating emissions of greenhouse gases and who knows what climatic tipping points in future years.

Then up spoke Ed Miliband, younger brother of the more famous British Foreign Secretary, David Miliband. “Point of order,” he called from the floor, and asked for an adjournment of the meeting. Rasmussen looked like a drowning man saved.

When the meeting resumed three hours later, with Rasmussen safely tucked in bed and diagnosed as “exhausted” by UN Secretary-General Ban Ki-moon, a procedural formula had been devised. A new chairman moved that the meeting “take note of the Copenhagen Accord,” with those agreeing to it able to add their names to its title and make pledges to stem their rising carbon dioxide emissions. The many critics of the leaders’ draft agreement, mostly in Latin America and Africa, were assuaged. The gavel fell. The accord was saved. Wild applause broke out.

The deadline for signing up to the Copenhagen Accord is February 1. Developing nations among the signatories will then also be able to dip into a “climate fund” created by the U.S. and other rich nations as part of the accord. The fund will begin with $10 billion a year and, if all goes according to their promises, will contain $100 billion a year by 2020.

It may seem a bizarre way to conduct business. But had Miliband not prevented Rasmussen from finishing his sentence, the accord would have had no UN status, countries would not have been asked to commit to emissions cuts, and the climate fund would have been stillborn. Other ways may have been found to achieve some of the same ends. Money usually talks. But the legitimacy of the UN process — the only basis on which most nations agree to participate in action on climate change — would have been lost.

The “noting” of the accord was a victory for climate diplomacy. And a relief to the galaxy of world leaders — Barack Obama, Britain’s Gordon Brown, Germany’s Angela Merkel, Russia’s Dmitry Medvedev, and Brazil’s President Luis Inacio Lula da Silva, among them — who, hours before, had prematurely claimed their work was done when they had agreed to the draft among themselves.

Heading for the airport, they failed to realize the anger that leaders not involved would feel about their exclusion from the dealmaking. And, since the accord was merely “noted” by the conference and not adopted, they had been wrong to claim before departure that, in the words of Gordon Brown, “for the first time, 192 nations of the UN have reached agreement on preventing warming beyond two degrees.” They did not. Only a later, legally binding UN treaty — if that can be achieved in 2010 — will accomplish that.

So the accord was a flawed diplomatic triumph. The show is still on the road. But a triumph for the planet? Not so fast. Across the Bella conference center, scientists who had evaded the tight attendance restrictions on observers were crunching numbers. And the scientists were gloomy.

The accord may set a goal to limit global warming to 2 degrees C (3.6 F), but it provides no emissions targets on how that should be achieved. On the basis of the commitments so far informally made by nations — which will be appended to the accord as countries sign it — the best estimates are that it will set the world on track to warming of between 3 and 3.5 degrees C, according to Michiel Schaeffer of the consulting group, ECOFYS, and Niklas Hoehne of Climate Analytics, who provided climate analysis for many nations at the conference.

Why this gap between rhetoric and reality? The first problem is the targets themselves. High hopes that many nations would up their promises in Copenhagen came to nothing. The U.S. would not go beyond its pre-conference promise to cut emissions by 14 to 17 percent from 2005 to 2020 — which more or less wipes out its increases since 1990 — the baseline used by the European Union for its pledge to cut by 20 percent. A European offer to go to 30 percent if others were generous was not activated.

China stuck with its pre-conference pledge to cut carbon intensity — that is, emissions per dollar of gross domestic product — by 40 to 45 percent between 2005 and 2020. That sounds good, but will not be enough to halt rising Chinese emissions. And as Premier Wen Jiabao helpfully told the conference, it is actually slightly less than the 46 percent reduction achieved between 1990 and 2005. So, it is arguably no more than business as usual.

India, Brazil, Mexico, South Africa, and others made similar pledges. It is the first time that developing nations have offered to make cuts in their emissions. But all insisted that the targets, while genuine, were voluntary and would not form part of any legally binding treaty. This was the central standoff throughout a conference characterized by repeated clashes on the issue between the U.S. and China. Hillary Clinton called the international verification and “transparency” of emissions promises, especially from China, a “deal breaker.” And so it proved.

But beyond the targets lies a legal morass over the precise definitions of what the target numbers mean. The text of the Copenhagen Accord contains even more loopholes than the 1997 Kyoto Protocol, say analysts.

The environment group WWF — reaching roughly the same conclusions as Climate Analytics and ECOFYS — calculates that rich-world promises to make cuts of 15 to 19 percent in their collective emissions between 1990 and 2020 could, once the loopholes are taken into account, result in an actual increase in emissions by 4 to 10 percent. Another unpublished assessment by Simon Terry of the Sustainability Council of New Zealand puts the increase at 2 to 8 percent.

The main loopholes are:

Hot air. The Kyoto Protocol gave Russia and other Eastern European countries rights to emit far more CO2 than they needed because of the collapse of their industries post-1990. They have accumulated large numbers of excess permits — 10.7 billion tons by the time the Kyoto Protocol expires in 2012, according to a European Union study. Potentially these credits, often called “hot air,” can be sold to other countries. The Copenhagen Accord appears to allow the spare credits to be carried forward for sale after 2012. If the EU bought them all to offset emissions between 2013 and 2020, it could achieve even a 30 percent “cut” in emissions without making any actual domestic cuts at all.

Carbon offsets. This is another way in which countries faced with difficult emissions reduction targets can offset them by investing in projects to cut someone else’s emissions. Done well, they allow carbon to be kept out of the atmosphere more cheaply. Done badly, they amount to carbon fraud, writing off emissions via green energy projects that were going to happen anyway. According to WWF, the European Union has already announced plans to make half a billion tons in emissions “cuts” through offsets in developing countries between 2012 and 2020. Other nations could triple that figure, it says.

Airline and shipping fuel. A notable failure of the Copenhagen Accord is the absence of proposals to limit growing emissions from international shipping and aircraft, which do not fall under the umbrella of anyone’s national emissions. Currently that is another loophole of one to two billion tons a year.

Forests. Copenhagen also failed to reach agreement on a plan to allow countries to claim either cash or carbon emissions credits for changes in managing forests to retain carbon. Insiders say the talks faltered because the U.S. and others refused to close a loophole that would allow countries to claim credits for improving things in one part of the country — by planting trees, for instance — while not being held to account for cutting down trees elsewhere within their borders. Unless fixed, another billion tons could slip through this loophole, says WWF.

Countries could close these loopholes before the final hoped-for legally binding agreement is signed. Then again, they might not.

So how could leaders fly out of Copenhagen, often in private jets, claiming success? More particularly why would some seasoned negotiators shrug their shoulders at the failures and insist that some progress was made?

There were two kinds of optimism on display in the final hours of the conference. The first was techno-optimism. Thus U.S. Congressman Edward Markey, co-author of the Waxman-Markey cap-and-trade bill,
spoke of a coming “technical revolution” in low-carbon energy systems. “It will be not unlike the telecom revolution,” he said, transforming energy technology worldwide far faster than predicted. “We will do far better than our two-degree goal,” he predicted. With several renewable technologies growing annually by 30 percent, even before the grand plans for “green jobs” in the U.S. and elsewhere, this may not be wishful thinking.

Diplomatic optimists, meanwhile, spoke of the progress they have seen in understanding of climate issues among world leaders. Standing in for his boss, Ban Ki-moon, UN assistant secretary general Robert Orr cited, with evident surprise, the leaders’ “meaningful discussion” of the respective scientific merits of adopting 2 degrees C or 1.5 degrees C as a warming limit.

“These were the most genuine negotiations I’ve ever seen leaders engaged in,” Orr said. Such deals are “usually pre-arranged, pre-cooked,” he added, but not this time.Such optimism is not necessarily well-placed. After concluding the accord, British Prime Minister Gordon Brown said: “This is the first step we are taking towards a green and low-carbon future for the world. But like all first steps, the steps are difficult.” He would not have known that almost the same words were used by one of his predecessors, John Major, after the Kyoto Protocol in 1997.

Even so, having followed climate talks since the Earth Summit in 1992, I am in many ways amazed at the progress made. It would have been hard to predict back in Rio that within two decades governments would be discussing cutting emissions by 50 or even 80 percent by mid-century. After all, they are talking about dismantling carbon-based energy systems that have underpinned economies since the industrial revolution. The trouble is that the science of climate change has become scarier, too, since 1992, and the threat seems much closer.

For all the travails and disappointment of the last two weeks, it is still possible to be optimistic that the world is approaching a genuine tipping point in how we get our energy. Will it come in time to prevent tipping points in the climate system? Frankly, nobody knows the answer to that.

Requiem for a Crowded Planet

This is what the failure of the climate talks means.


klamm.de - Geld. News. Promotion!

By George Monbiot. Published in the Guardian 21st December 2009
The last time global negotiations collapsed like this was in Doha in 2001. After the trade talks fell apart, the World Trade Organisation (WTO) assured the delegates that there was nothing to fear: they would move to Mexico, where a deal would be done. The negotiations ran into the sand of the Mexican resort of Cancun, never to re-emerge. After eight years of dithering, nothing has been agreed.
When the climate talks in Copenhagen ended in failure last week, Yvo de Boer, the man in charge of the process, urged us not to worry: everything will be sorted out “in Mexico one year from now.”(1) Is Mexico the diplomatic equivalent of the Pacific garbage patch: the place where failed negotiations go to die?
De Boer might pretend that this is just a temporary hitch, but he knows what happens when talks lose momentum. A year ago I asked him what he feared most. This is what he said. “The worst-case scenario for me is that climate becomes a second WTO. … Copenhagen, for me, is a very clear deadline that I think we need to meet, and I am afraid that if we don’t, then the process will begin to slip, and like in the trade negotiations, one deadline after the other will not be met, and we sort of become the little orchestra on the Titanic.”(2)
We can live without a new trade agreement; we can’t live without a new climate agreement. One of the failings of the people who have tried to mobilise support for a climate treaty is that we have made the issue too complicated. So here is the simplest summary I can produce of why this matters.
Human beings can live in a wider range of conditions than almost any other species. But the climate of the past few thousand years has been amazingly kind to us. It has enabled us to spread into almost all regions of the world and to grow into the favourable ecological circumstances it has created. We currently enjoy the optimum conditions for supporting seven billion people.

A shift in global temperature reduces the range of places than can sustain human life. During the last ice age, humans were confined to low latitudes. The difference in the average global temperature between now and then was four degrees centigrade. Global warming will have the opposite effect, driving people into higher latitudes, principally as water supplies diminish.
Food production at high latitudes must rise as quickly as it falls elsewhere, but this is unlikely to happen. According to the body that summarises the findings of climate science, the Intergovernmental Panel on Climate Change, the potential for global food production “is very likely to decrease above about 3C”(3). The panel uses the phrase “very likely” to mean a probability of above 90%(4). Unless a strong climate deal is struck very soon, the probable outcome is a rise of three or more degrees by the end of the century.
Even in higher latitudes the habitable land area will decrease as the sea level rises. The likely rise this century - probably less than a metre - is threatening only to some populations, but the process does not stop in 2100. During the previous interglacial period, about 125,000 years ago, the average global temperature was around 1.3 degrees higher than it is today, as a result of changes in the earth’s orbit around the sun. A new paper in the scientific journal Nature shows that sea levels during that period were between 6.6 and 9.4 metres higher than today’s(5). Once the temperature had risen, the expansion of sea water and the melting of ice caps in Greenland and Antarctica was unstoppable. I wonder whether the government of Denmark, whose atrocious management of the conference contributed to its failure, would have tried harder if its people knew that in a few hundred years they won’t have a country any more.
As people are displaced from their homes by drought and sea level rise, and as food production declines, the planet will be unable to support the current population. The collapse in human numbers is unlikely to be either smooth or painless: while the average global temperature will rise gradually, the events associated with it will come in fits and starts: sudden droughts and storm surges.
This is why the least developed countries, which will be hit hardest, made the strongest demands in Copenhagen. One hundred and two poor nations called for the maximum global temperature rise to be limited not to two degrees but to 1.5. The chief negotiator for the G77 bloc complained that Africa was being asked “to sign a suicide pact, an incineration pact, in order to maintain the economic dominance of a few countries”(6).
The immediate reason for the failure of the talks can be summarised in two words: Barack Obama. The man elected to put aside childish things proved to be as susceptible to immediate self-interest as any other politician. Just as George Bush did in the approach to the Iraq war, Obama went behind the backs of the UN and most of its member states and assembled a coalition of the willing to strike a deal which outraged the rest of the world. This was then presented to poorer nations without negotiation; either they signed it or they lost the adaptation funds required to help them survive the first few decades of climate breakdown.
The British and American governments have blamed the Chinese government for the failure of the talks. It’s true that the Chinese worked hard to mess them up, but Obama also put Beijing in an impossible position. He demanded concessions while offering nothing. He must have known the importance of not losing face in Chinese politics: his unilateral diplomacy amounted to a demand for self-abasement. My guess is that this was a calculated manoeuvre guaranteed to produce instransigence, whereupon China could be blamed for the outcome he wanted.
Why would Obama do this? You have only to see the relief in Democratic circles to get your answer. Pushing a strong climate programme through the Senate, many of whose members are wholly owned subsidiaries of the energy industry, would have been the political battle of his life. Yet again, the absence of effective campaign finance reform in the US makes global progress almost impossible.
So what happens now? That depends on the other non-player at Copenhagen: you. For the past few years good, liberal, compassionate people - the kind who read the Guardian every day - have shaken their heads and tutted and wondered why someone doesn’t do something. Yet the number taking action has been pathetic. Demonstrations which should have brought millions onto the streets have struggled to mobilise a few thousand. As a result the political cost of the failure at Copenhagen is zero.
Is this music not to your taste sir, or madam? Perhaps you would like our little orchestra to play something louder, to drown out that horrible grinding noise.

Carbon Price Drops Are True Signal That Copenhagen Was a Cop-Out

Was Copenhagen historic or a failure (or both)? To discern the value of the Copenhagen deal through the din of spin, look no further than the 9% drop in the European carbon market on Monday, where confidence vanished following the President Obama's "historic accord."

klamm.de - Geld. News. Promotion!

Last week, President Obama made an audacious effort to save what was a floundering process in Copenhagen. Unfortunately, his administration's claim of "historic accord" is little but spin. What the world was waiting for -- the sinking island nations, the 300,000 that the World Health Organization says die each year from global warming, and the carbon markets -- were binding agreements to cut carbon pollution, end tropical deforestation by 2015, and provide financing to assist developing countries in leap-frogging dirty development with clean energy.
What they got was business as usual. Earlier this year the House passed a deeply flawed climate bill that falls short of what the science says is needed to roll back climate change. The bill's contents were what the president promised in Copenhagen, and his words were met with disappointment the world over.

There is spin from all sides about just what happened in Denmark. Let me share my observations from someone with a global, not just U.S., perspective. The European Union, already actively engaged in the Kyoto Protocol, offered to cut its pollution by 20% and said they would go up to 30% if the U.S. put more ambitious goals on the table. The EU also pledged 30 billion euro per year for financing clean technology and other initiatives in the developing world. China, already outpacing the U.S. in the development and deployment of renewable energy technologies, offered to decrease the energy intensity of its emerging economy. India pledged the same.
The U.S. pressed China to allow its efforts to cut global warming pollution to be independently measured. China resisted the U.S. proposal to allow the U.S. to come in and inspect its industry, but felt that the negotiations with the U.S. were making progress on this point when it accepted an EU proposal on reporting and occasional checks. Meanwhile, the U.S. was punching loopholes into the pact.
The deal could possibly be sealed if the U.S. offered financing for developing countries and resolved the issue of transparency with China.
Enter Hillary Clinton, offering to somehow figure out how to give an unstated contribution of money from an unknown source to a $100 billion fund. In the process, she offended the Chinese premier, who was in such a fury that his negotiating staff was in a panic.
Enter President Obama. His speech, clearly written for one audience - the U.S. Senate - said three things to the heads of state in the room: hey foreign leaders, we don't want foreign oil; hey China, even though we've been building trust and negotiating all year well, I'm going to scold you for the benefit of domestic politics; and hey world: even though these are negotiations, I have nothing to offer. It's my way or the highway.
The President laid out what the U.S. had offered the world for the last eight months, budging on nearly nothing. He put forward a goal of cutting pollution by 4% below 1990 levels - about one tenth of what the EU offered. In fairness, he had little to offer. The combination of the President's hesitance to lead to overcome special interests to achieve his own stated objectives - whether on a public option in health care or pollution reductions of any respectable size - and the power of the coal and oil lobbies put the his negotiators in the awkward positoin of negotiating without very much to give.

The Chinese premier stormed out of the room and refused to meet with the President. Finally, the President secured a meeting and hammered out a deal that has the value of the carbon markets today: very little.
So few people had a clue about the "deal" that when President Obama later announced it the EU negotiators were still forging a deal and G77 delegates were talking in the halls about the perilous state of the Summit. Ultimately, most signed on, because if they did not, then their countries would not get a cut of a $30 billion package for clean energy and adapting to current global warming. A few brave countries, not wanting to be bought, said "no" to the deal. The historic accord was "noted" by the process, a nod to its existence.
The world still expects great things of President Obama and the US, but we cannot expect him to save the world on his own. We can expect - and must demand - that the president leads in recommitting the U.S. to the democratic UN process, doubles his efforts through the EPA and other methods to cut global warming pollution without the loopholes, clean air act rollbacks, impending nuclear disasters, and green light for coal that we see in current legislation, and approaches the negotiations as what they are - negotiations to save millions of lives, dozens of countries, 70% of the world's species, and a future that is worth passing on to our children.

Global Climate Change: Overview

Global Climate Change: Overview
Image of the first tornado captured by the National Severe Storms Laboratory Doppler radar in Union City, Oklahoma on May 24, 1973.Global climate change is a change in the long-term weather



patterns that characterize the regions of the world. The term "weather" refers to the short-term (daily) changes in temperature, wind, and/or precipitation of a region (Merritts et al. 1998). Weather is influenced by the sun. The sun heats the earth's atmosphere and its surface causing air and water to move around the planet. The result can be as simple as a slight breeze or as complex as the formation of a tornado (see above).

Some of the sun's incoming long wave radiation is reflected back to space by aerosols. Aerosols are very small particles of dust, water vapor, and chemicals in Earth's atmosphere. In addition, some of the sun's energy that has entered Earth's atmosphere is reflected into space by the planet's surface. The reflectivity of Earth's surface is called albedo. Both of these reflective processes have a cooling affect on the planet.
The greenhouse effect is a warming process that balances Earth's cooling processes. During this process, sunlight passes through Earth's atmosphere as short-wave radiation. Some of the radiation is absorbed by the planet's surface. As Earth's surface is heated, it emits long wave radiation toward the atmosphere. In the atmosphere, some of the long wave radiation is absorbed by certain gases called greenhouse gases. Greenhouse gases include carbon dioxide (CO2), Chlorofluorocarbons (CFC's), methane (CH4), nitrous oxide (N20), tropospheric ozone (O3), and water vapor. Each molecule of greenhouse gas becomes energized by the long wave radiation. The energized molecules of gas then emit heat energy in all directions. By emitting heat energy toward Earth, greenhouse gases increase Earth's temperature. Note that the warning mechanism for the "greenhouse effect" is NOT exactly the same as the warning mechanism of greenhouse walls. While greenhouse gases absorb long wave radiation then emit heat energy in all directions, greenhouse walls physically trap heat inside of greenhouses and prevent it from escaping to the atmosphere.
The greenhouse effect is a natural occurrence that maintains Earth's average temperature at approximately 60 degrees Fahrenheit. The greenhouse effect is a necessary phenomenon that keeps all Earth's heat from escaping to the outer atmosphere. Without the greenhouse effect, temperatures on Earth would be much lower than they are now, and the existence of life on this planet would not be possible. However, too many greenhouse gases in Earth's atmosphere could increase the greenhouse effect. This could result in an increase in mean global temperatures as well as changes in precipitation patterns.

Please have someone assist you with this.When weather patterns for an area change in one direction over long periods of time, they can result in a net climate change for that area. The key concept in climate change is time. Natural changes in climate usually occur over; that is to say they occur over such long periods of time that they are often not noticed within several human lifetimes. This gradual nature of the changes in climate enables the plants, animals, and microorganisms on earth to evolve and adapt to the new temperatures, precipitation patterns, etc.
The real threat of climate change lies in how rapidly the change occurs. For example, over the past 130 years, the 7mean global temperature appears to have risen 0.6 to 1.2 degrees Fahrenheit (0.3 to 0.7 degrees Celsius). These temperatures changes are depicted in the graph below from the EPA's Global Warming site. The increasing steepness of the curve suggests that changes in mean global temperature have occurred at greater rates over time. Further evidence suggests that future increases in mean global temperature may occur at a rate of 0.4 degrees Fahrenheit (0.2 degrees Celsius) each decade.

Image of a graph showing the Global Temperature Changes from 1861-1996.  Please have someone assist you with this.The geological record--the physical evidence of the results of processes that have occurred on Earth since it was formed--provides evidence of climate changes similar in magnitude to those in the the above graph. This means during the history of the earth, there have been changes in global temperatures similar in size to these changes. However, the past changes occurred at much slower rates, and thus they were spread out over long periods of time. The slow rate of change allowed most species enough time to adapt to the new climate. The current and predicted rates of temperature change, on the other hand, may be harmful to ecosystems. This is because these rates of temperature change are much faster than those of Earth's past. Many species of plants, animals, and microorganisms may not have enough time to adapt to the new climate. These organisms may become extinct.

Summing up

The extremely complex interrelations between human activity and natural forces—air masses, winds, ocean currents, evaporation, and precipitation—means that researchers from many fields pool their efforts in an attempt to understand how the climate is reacting to changes. But this complexity also means that knowing what the climate will be like in fifty or one hundred years is among the most challenging problems in science.

Some of the changes researchers in all these areas are exploring may seem small, especially in relation to the typical temperature changes associated with daily and seasonal cycles. But although regional and short-term temperatures do fluctuate over a wide range, global temperatures are generally very stable. Indeed, during the last Ice Age (about 20,000 years ago), the average global temperature was only about 5°C cooler than it is today.

The fact that seemingly small changes can have dramatic effects is one reason why an understanding of the data, techniques, and controversies of global climate research is so fundamental to understanding the phenomenon itself. We’ve collected and discussed some of the data on the following pages to give you a sense of how the problem is being studied—and what all that research may be telling us.

what We Know: Underlying Processes

Living things don’t just respond to the climate—they affect it as well. Plants consume carbon dioxide and produce oxygen through photosynthesis. Earthbound plants take carbon dioxide directly from the air; drifting photosynthetic microorganisms called phytoplankton use carbon dioxide dissolved in water.



It is estimated that photosynthesis is a “sink” for around 60 billion tons of carbon every year, by far the strongest mechanism for carbon dioxide removal from the atmosphere. (This removal is almost exactly balanced by the respiration of animals, which combines oxygen with hydrocarbons to produce carbon dioxide and water vapor.)

Increases in the level of carbon dioxide in the atmosphere could promote plant growth. If the planet’s vegetation grows stronger and more widespread, it could take in more of the atmospheric carbon dioxide, preventing a runaway greenhouse effect. This controversial “greening hypothesis” has led to more research exploring the connections between global climate and the earth’s biological systems. (See “Greening in the North” on this site to learn more about how climate change will affect vegetation.)

Phytoplankton bloom
This satellite image shows phytoplankton in the ocean waters off the southeastern United States. Phytoplankton, like terrestrial plants, consume carbon dioxide in the process of photosynthesis.
The biosphere is also the source of aerosols, such as spores, pollen, bacteria, and other particles. These aerosols scatter incoming radiation, affecting the energy budget. And some marine organisms produce sulfate particles, which act as condensation centers for cloud formation. As the number of such condensation centers increases, more, and consequently smaller, cloud droplets are formed. A cloud made of many small droplets is highly reflective and prevents solar radiation from reaching the earth. Any anthropogenic (human) production of sulphur could produce a similar effect, moderating a warming trend.
Evidences and Uncertainties
Many species live in very sensitive ecological niches, so even small changes in temperature or precipitation could drastically alter their ability to survive. Oak trees in the midwestern U.S., for example, may not tolerate an average temperature only a few degrees higher than current temperatures. And even increases in ocean temperatures of as little as 1°C over two or three days can cause coral—organisms particularly sensitive to long-term variations in climate—to lose their symbiotic algae, which are essential for their nutrition. When the algae die, corals are “bleached” and appear white. (See “Current Coral Bleaching Hot Spots” on this site to learn more.)

Because all species are linked in complex webs of predator, prey, and habitat, impacts on one species always affect others—and it’s extremely difficult to predict how those effects will manifest themselves. Changing the life cycles of key species in food chains may well affect an entire ecosystem.

Additionally, the ability of many species to adapt to changing climate through migration is much different than it was in earlier centuries. Habitats and migration routes are now broken up by housing, industry, roadways, and other development. Species also need time to make adaptations, but the rate of climate change appears to be increasing: Over the last 16,000 years, the rate of increase in global temperatures has been about 1°C for every 4,000 years—and yet, some predictions now suggest that we may see another 1° increase over the next one hundred years.

Some species may actually be helped by warmer temperatures, of course—but this may not necessarily be good news. Increasing the populations of some species may have serious effects on human health.

Deforestation
Each of these pinwheel patterns centers on a small community of soybean farmers in eastern Bolivia. Roads and fields have subdivided the tropical dry forest.
For example, even small increases in global temperatures, especially if they’re accompanied by flooding, may drive an increase in the mosquito populations in tropical areas, leading to much greater transmission rates of diseases like malaria. (See “Risk of Malaria Transmission” on this site to learn about another potential health risk.) And again, changing the balance of species affects the way entire ecosystems function, with unknown consequences.
