Green Policies in California Generated Jobs, Study Finds

October 20, 2008 By FELICITY BARRINGER

OAKLAND, Calif. — California’s energy-efficiency policies created nearly 1.5 million jobs from 1977 to 2007, while eliminating fewer than 25,000, according to a study to be released Monday.

The study, conducted by David Roland-Holst, an economist at the
Center for Energy, Resources and Economic Sustainability at the
University of California, Berkeley, found that while the state’s
policies lowered employee compensation in the electric power industry
by an estimated $1.6 billion over that period, it improved compensation
in the state over all by $44.6 billion.

Built into that figure were increases of $1.2 billion in the light
industrial sector, $11.2 billion in wholesale and retail trade, $7.3
billion in the financial and insurance sectors and $17.8 billion in the
service sector.

“Consumers were able to reduce energy spending,” the study said, adding that “these savings were diverted to other demand.”

“When consumers shift one dollar of demand from electricity to
groceries,” the report said, they create jobs among retailers,
wholesalers, food processors and other businesses.

The study, which examined household spending, comes as state and
regional initiatives on climate-change policies have been gathering
momentum. At the same time, arguments have sharpened over how much it
will cost the economy to cut the emission of greenhouse gases like
carbon dioxide produced by burning fossil fuels, which are linked to climate change.

Roughly half the country’s electric power is generated by burning
coal, the fuel that produces among the highest greenhouse-gas emissions
of any in widespread use.

Some economists focus their studies on the cost of converting the
power grid to run on low-carbon technologies, like wind energy, or the
cost of developing technologies to separate the carbon dioxide from
coal-plant emissions and bury it underground. Others focus on the job
creating potential of new energy industries.

The Berkeley study is different in that it focuses as much on
historical data as on modeling the future. California’s
energy-efficiency policies were adopted in 1978, long before the
widespread push for greenhouse-gas reductions, but the data they
provide is highly relevant to the current economic debate.

Professor Roland-Holst said that he based his calculations on
residential spending on electricity over the last 30 years, factoring
in both the decrease in per-capita demand for electricity — now 40
percent below the national average — and the increase in California’s
electrical rates, which were about 40 percent above the national
average in June, the latest month for which data is available.
Household spending represents more than 70 percent of the gross state
product.

Historically, Professor Roland-Holst said, the decrease in
per-capita demand for electricity outstripped the increase in rates.
Much of the economic growth, the study said, was driven by both
efficiency standards for large appliances like refrigerators and for
residential and commercial buildings.

In an interview, Professor Roland-Holst said, “What I wanted to do
to support the forward-looking vision is go back and look at the
evidence we have in front of us.”

In two months, California is set to adopt broad policies to enforce
a new cap on greenhouse gas emissions signed into law two years ago.
More detailed regulations will then be developed; that process is
likely to be contentious, as it divides the overall costs of the new
program among competing sectors of the state’s economy.

speaking of oysters...


A Warning From the Sea
Oyster ’seeds’ are dying as Pacific Coast waters grow warmer.

by Kenneth R. Weiss
QUILCENE, WASH. – For decades, the unwritten motto at shellfish hatcheries in the Pacific Northwest was “Better oysters through science.”0713 01 1

Scientists mated the heartiest, fastest-growing stock to produce
plumper, sweeter oysters for slurping raw on the half-shell or frying up to dip in tangy sauces.


They probed the genetic code to select for the most desirable traits of the Pacific oyster, an import from Japan that now weighs in, pound for pound, as the No. 1 aquacultured crop in the world: 4.5 million tons a year (shells included) valued at $3 billion.

They even bred out sexual organs that at certain times of the year
can take up more than a third of an oyster’s body weight and give it a
soft, mushy texture.

With selective breeding and genetic fingerprinting, they were on
their way to developing a super oyster resistant to summer mortality,
keeping one step ahead of a warmer, more polluted planet. Or so they
thought.

Suddenly, oyster research bogged down as a riotous bloom of bacteria
went on a West Coast killing spree, wiping out billions of oyster
larvae.

The outbreak first shut down an oyster brood stock program run by
Oregon State University in Newport, Ore., in 2005. “All we saw was our
larvae were dying,” said fisheries professor Chris Langdon, “and we
couldn’t put our finger on why.”

Then the microscopic culprit overran commercial hatcheries in
Washington and Oregon, crippling production over the last couple of
years and causing a shortage of oyster “seed” needed to replant
tideland farms from Southern California to Canada.

“It’s pretty scary,” said Sue Cudd, owner of Whiskey Creek Shellfish
Hatchery in Netarts, Ore. The hatchery, she said, has been drowning in
costs and failing to produce sufficient oyster larvae for West Coast
shellfish farmers. “We almost decided to close, and people panicked. I
realized if I go out of business, I take a lot of people with me.”

Science has identified the culprit, a strain of bacteria called Vibrio tubiashii, which is harmless to humans but fatal to baby oysters. It attacks them in their vulnerable, free-swimming larval stage before they settle to the seafloor, latch onto rocks or other oysters and grow thick shells.

The Vibrio blooms appear to be linked to warmer waters in estuaries and the oxygen-starved “dead zones” that have showed up this decade off the coast of Oregon and Washington, researchers said.

These low-oxygen waters correlate with stronger winds coming from a warming planet.

Scientists note that Vibrio tubiashii has an advantage over
other microscopic life in the sea. This bacterium thrives in
oxygen-starved dead zones, feasting on decaying plant and animal matter littering the seafloor. And when brought to the surface with water welling up from the deep, it can switch survival strategies to flourish in warm, well-oxygenated waters.

Researchers were not surprised to find this type of bacteria in
seawater but were stunned that it had become so dominant over other
microbes: It was nearly a pure concentration of this one bacteria, one
that happens to be deadly to oyster larvae.

“It seems to be logical that the dead zone is playing a role,” said
Ralph Elston, who runs a veterinary medical practice in Sequim, Wash.,
that offers advice to shellfish farmers. “It’s the perfect bacterial
setup, and we get these explosive blooms along the coast.”

Edmund Jones removed a pinch of brown silt and smeared it across a
glass slide. Tanks of seawater gurgled in the background. A salty tang
hung in the moist air.

Jones, who manages Taylor Shellfish Farms’ hatchery here on Dabob
Bay, fiddled with a knob, bringing into focus a dozen or more 9-day-old oyster larvae.

He pointed out a few healthy ones, dark round discs scuttling
around, propelled by hair-like cilia. Most didn’t move at all. Light
shined through them, revealing empty insides. They hadn’t been feeding. If they weren’t dead already, they were dying.

“When your job is to grow larvae and you see that on the screen,”
Jones said, “it’s extremely frustrating to see. Unfortunately, what
this tells me is we’ll probably be dumping that tank tomorrow.”

That meant jettisoning 30 million larvae.

Failures of this kind have become so regular that Taylor’s hatchery
is producing less than a quarter of its capacity, far short of what is
needed to reseed its oyster beds or to sell to other shellfish farmers
looking to do the same.

The shortage of oyster seed, or “spat,” will have its greatest
effect in several years, when oyster beds left fallow would otherwise
be ready for harvest. That may set the stage for shortages and economic upheaval in the West Coast’s $110-million-a-year shellfish industry, said Bill Dewey, a division manager at Taylor Shellfish.

“We don’t have the seed to replace these crops you see here,” Dewey
said, standing on a Samish Bay tidal flat in hip-waders, watching a
work crew fill baskets with 4- and 5-year-old oysters.

Shellfish growers, Dewey said, often provide “the first indication
that there’s a problem out there, because the animals we are farming
are telling us that.”

What the dead larvae are saying is that something is wrong with
coastal waters, he said. “Whether it’s climate change” or something
else, he said, “it’s likely something that man has done to our
environment that is creating this problem for us.”

Alan Trimble, a researcher at the University of Washington, has
noticed similar problems in the wild. Sampling seawater in Willapa Bay, Wash., he found that the oyster and clam larvae had disappeared in the last two years from waters where bacteria counts had been high.

Hatchery operators inadvertently pump in the bacteria along with
seawater they use to bathe their infant oysters and grow the green
algae used to feed larvae. The microbes even drift in on the sea
breeze, launched into the air by bubbles bursting at the ocean’s
surface.

The shutdown of Oregon State’s experimental hatchery prompted
university officials to develop a multistage filtering system that
blasts seawater with ultraviolet light to kill bacteria, skims the
harmful bacteria’s lingering toxins and then reinoculates the cleaned
water with a healthful balance of microbes.

The Whiskey Creek Hatchery has adopted the same filtering system,
which helped revive half of its larvae production. The hatchery run by
Taylor Shellfish, the largest grower in the country, is experimenting
with similar techniques to get its production going again.

Growers have sought the help of university researchers and asked Congress for emergency funds to look for solutions.

The U.S. Department of Agriculture, which funds the Molluscan
Broodstock Program at Oregon State’s hatchery, is exploring microbial
warfare.

Gary Richards, a USDA researcher at the University of Delaware, has
been screening seawater samples to find a virus, or bacteriophage, that would seek out and destroy Vibrio tubiashii. Marine bacteria
often have such natural enemies. An intervention, such as releasing the right “phage,” as they are called, could avoid “an ecological disaster of monumental proportions,” Richards wrote in an e-mail to scientists and hatchery managers.

As filter feeders, shellfish clean seawater of excess algae and
nutrients, maintaining healthy coastal waters. When oysters disappear,
as they did in the Chesapeake Bay, an estuary’s water can turn murky
and foul.

“With the loss of oysters, the water in the Chesapeake became more
turbid, restricting light penetration to plants and sea life, and the
higher nutrient levels made algal blooms more common,” Richards wrote.
“The West Coast needs to avoid this at all cost.”

So scientists like Donal T. Manahan and Dennis Hedgecock at USC,
among others, have spent decades hovering over bubbling tanks of
oysters to improve on nature. They’ve been selecting stocks with more
productive pedigrees that offer the double benefit of cleaning coastal
waters and multiplying the bounty of this gastronomic treat.

“Our hybrids do better than wild oysters,” producing two to three
times more oyster meat per acre of shellfish beds, Hedgecock said. Yet
as the bacterial outbreak reminded them, the first step of any
successful breeding program is to make sure oysters don’t die.

The episode has moved disease resistance to the top of the list of
characteristics researchers want to tease out of the mollusk’s genetic
code, said Langdon, from Oregon State’s hatchery.

“We need to find those oysters that are most resistant to this
bacterium,” he said. “This whole problem has created a new target for
the selective-breeding program.”

Living on the Ice Shelf

Published on Thursday, June 26, 2008 by TomDispatch.com
Living on the Ice Shelf, Humanity's Meltdown

by Mike Davis

1. Farewell to the Holocene

Our world, our old world that we have inhabited for the last 12,000 years, has ended, even if no newspaper in North America or Europe has yet printed its scientific obituary.

This February, while cranes were hoisting cladding to the 141st floor of the Burj Dubai tower (which will soon be twice the height of the Empire State Building), the Stratigraphy Commission of the Geological Society of London was adding the newest and highest story to the geological column.

The London Society is the world's oldest association of Earth scientists, founded in 1807, and its Commission acts as a college of cardinals in the adjudication of the geological time-scale. Stratigraphers slice up Earth's history as preserved in sedimentary strata into hierarchies of eons, eras, periods, and epochs marked by the "golden spikes" of mass extinctions, speciation events, and abrupt changes in atmospheric chemistry.

In geology, as in biology or history, periodization is a complex, controversial art and the most bitter feud in nineteenth-century British science — still known as the "Great Devonian Controversy" — was fought over competing interpretations of homely Welsh Graywackes and English Old Red Sandstone. More recently, geologists have feuded over how to stratigraphically demarcate ice age oscillations over the last 2.8 million years. Some have never accepted that the most recent inter-glacial warm interval — the Holocene — should be distinguished as an "epoch" in its own right just because it encompasses the history of civilization.

As a result, contemporary stratigraphers have set extraordinarily rigorous standards for the beatification of any new geological divisions. Although the idea of the "Anthropocene" — an Earth epoch defined by the emergence of urban-industrial society as a geological force — has been long debated, stratigraphers have refused to acknowledge compelling evidence for its advent.

At least for the London Society, that position has now been revised.

To the question "Are we now living in the Anthropocene?" the 21 members of the Commission unanimously answer "yes." They adduce robust evidence that the Holocene epoch — the interglacial span of unusually stable climate that has allowed the rapid evolution of agriculture and urban civilization — has ended and that the Earth has entered "a stratigraphic interval without close parallel in the last several million years." In addition to the buildup of greenhouse gases, the stratigraphers cite human landscape transformation which "now exceeds [annual] natural sediment production by an order of magnitude," the ominous acidification of the oceans, and the relentless destruction of biota.

This new age, they explain, is defined both by the heating trend (whose closest analogue may be the catastrophe known as the Paleocene Eocene Thermal Maximum, 56 million years ago) and by the radical instability expected of future environments. In somber prose, they warn that "the combination of extinctions, global species migrations and the widespread replacement of natural vegetation with agricultural monocultures is producing a distinctive contemporary biostratigraphic signal. These effects are permanent, as future evolution will take place from surviving (and frequently anthropogenically relocated) stocks." Evolution itself, in other words, has been forced into a new trajectory.

2. Spontaneous Decarbonization?

The Commission's coronation of the Anthropocene coincides with growing scientific controversy over the 4th Assessment Report issued last year by the Intergovernmental Panel on Climate Change (IPCC). The IPCC is mandated to establish scientific baselines for international efforts to mitigate global warming, but some of the most prominent researchers in the field are now challenging its reference scenarios as overly optimistic, even pie-in-the-sky thinking.

The current scenarios were adopted by the IPCC in 2000 to model future global emissions based on different "storylines" about population growth as well as technological and economic development. Some of the Panel's major scenarios are well known to policymakers and greenhouse activists, but few outside the research community have actually read or understood the fine print, particularly the IPCC's confidence that greater energy efficiency will be an "automatic" byproduct of future economic development. Indeed all the scenarios, even the "business as usual" variants, assume that at least 60% of future carbon reduction will occur independently of greenhouse mitigation measures.

The Panel, in effect, has bet the ranch, or rather the planet, on unplanned, market-driven progress toward a post-carbon world economy, a transition that implicitly requires wealth generated from higher energy prices ultimately finding its way to new technologies and renewable energy. (The International Energy Agency recently estimated that it would cost $45 trillion to halve greenhouse gas emissions by 2050.) Kyoto-type accords and carbon markets are designed — almost as an analogue to Keynesian "pump-priming" — to bridge the shortfall between spontaneous decarbonization and the emissions targets required by each scenario. Serendipitously, this reduces the costs of mitigating global warming to levels that align with what seems, at least theoretically, to be politically possible, as expounded in the British Stern Review on the Economics of Climate Change of 2006 and other such reports.

Critics argue, however, that this represents a heroic leap of faith that radically understates the economic costs, technological hurdles, and social changes required to tame the growth of greenhouse gases. European carbon emissions, for example, are still rising (dramatically in some sectors) despite the European Union's much praised adoption of a cap-and-trade system in 2005. Likewise there has been little evidence in recent years of the automatic progress in energy efficiency that is the sine qua non of the IPCC scenarios. Although The Economist characteristically begs to differ, most energy researchers believe that, since 2000, energy intensity has actually risen; that is, global carbon dioxide emissions have kept pace with, or even grown marginally faster than, energy use.

Coal production, especially, is undergoing a dramatic renaissance, as the nineteenth century has returned to haunt the twenty-first century. Hundreds of thousands of miners are now working under conditions that would have appalled Charles Dickens, extracting the dirty mineral that allows China to open two new coal-fueled power stations every week. Meanwhile, the total consumption of fossil fuels is predicted to increase at least 55% over the next generation, with international oil exports doubling in volume.

The United Nations Development Program, which has made its own study of sustainable energy goals, warns that it will require "a 50 percent cut in greenhouse gas emissions worldwide by 2050 against 1990 levels" to keep humanity outside the red zone of runaway warming (usually defined as a greater than two degrees centigrade increase this century). Yet the International Energy Agency predicts that, in all likelihood, such emissions will actually increase in this period by nearly 100% — enough greenhouse gas to propel us past several critical tipping points.

Even while higher energy prices are pushing SUVs towards extinction and attracting more venture capital to renewable energy, they are also opening the Pandora's box of the crudest of crude oil production from Canadian tar sands and Venezuelan heavy oil. As one British scientist has warned, the very last thing we should wish for (under the false slogan of "energy independence") is new frontiers in hydrocarbon production that advance "humankind's ability to accelerate global warming" and slow the urgent transition to "non-carbon or closed-carbon energy cycles."

3. Fin-du-Monde Boom

What confidence should we place in the capacity of markets to reallocate investment from old to new energy or, say, from arms expenditures to sustainable agriculture? We are propagandized incessantly (especially on public television) about how giant companies like Chevron, Pfizer Inc., and Archer Daniels Midland are hard at work saving the planet by plowing profits back into the kinds of research and exploration that will ensure low-carbon fuels, new vaccines, and more drought-resistant crops.

As the current ethanol-from-corn boom, which has diverted 100 million tons of grain from human diets mainly to American car engines, so appallingly demonstrates, "biofuel" may be a euphemism for subsidies to the rich and starvation for the poor. Likewise "clean coal," despite a vigorous endorsement from Senator Barack Obama (who also champions ethanol), is, at present, simply a huge deception: a $40 million advertising and lobbying campaign for a hypothetical technology that BusinessWeek has characterized as "being decades away from commercial viability."

Moreover there are disturbing signs that energy companies and utilities are reneging on their public commitments to the development of carbon-capture and alternative energy technologies. The Bush administration's "marquee demonstration project," FutureGen, was scrapped this year after the coal industry refused to pay its share of the public-private "partnership"; similarly, most U.S. private-sector carbon-sequestration initiatives have recently been cancelled. In the United Kingdom, meanwhile, Shell has just pulled out of the world's largest wind-energy project, the London Array. Despite heroic levels of advertising, energy corporations, like pharmaceutical companies, prefer to overgraze the commons, while letting taxes, not profits, pay for whatever urgent, long-overdue research is actually undertaken.

On the other hand, the spoils from high energy prices continue to gush into real estate, skyscrapers, and financial assets. Whether or not we are actually at the summit of Hubbert's Peak — that peak oil moment — whether or not the oil-price bubble finally bursts, what we are probably witnessing is the largest transfer of wealth in modern history.

An eminent Wall Street oracle, McKinsey Global Institute, predicts that if crude oil prices remain above $100 per barrel — they are, at the moment, approaching $140 a barrel — the six countries of the Gulf Cooperation Council alone will "reap a cumulative windfall of almost $9 trillion by 2020." As in the 1970s, Saudi Arabia and its Gulf neighbors, whose total gross domestic product has almost doubled in just three years, are awash in liquidity: $2.4 trillion in banks and investment funds according to a recent estimate by The Economist. Regardless of price trends, the International Energy Agency predicts, "more and more oil will come from fewer and fewer countries, primarily the Middle East members of OPEC [The Organization of the Petroleum Exporting Countries]."

Dubai, which has little oil income of its own, has become the regional financial hub for this vast pool of wealth, with ambitions to eventually compete with Wall Street and the City of London. During the first oil shock in the 1970s, much of OPEC's surplus was recycled through military purchases in the United States and Europe, or parked in foreign banks to become the "subprime" loans that eventually devastated Latin America. In the wake of the attacks of 9/11, the Gulf states became far more cautious about entrusting their wealth to countries, like the United States, governed by religious fanatics. This time around, they are using "sovereign wealth funds" to achieve a more active ownership in foreign financial institutions, while investing fabulous amounts of oil revenue to transform Arabia's sands into hyperbolic cities, shopping paradises, and private islands for British rock stars and Russian gangsters.

Two years ago, when oil prices were less than half of the current level, The Financial Times estimated that planned new construction in Saudi Arabia and the emirates already exceeded $1 trillion dollars. Today, it may be closer to $1.5 trillion, considerably more than the total value of world trade in agricultural products. Most of the Gulf city-states are building hallucinatory skylines — and, among them, Dubai is the unquestionable superstar. In a little more than a decade, it has erected 500 skyscrapers, and currently leases one-quarter of all the high-rise cranes in the world.

This super-charged Gulf boom, which celebrity architect Rem Koolhaas claims is "reconfiguring the world," has led Dubai developers to proclaim the advent of a "supreme lifestyle" represented by seven-star hotels, private islands, and J-class yachts. Not surprisingly, then, the United Arab Emirates and its neighbors have the biggest per capita ecological footprints on the planet. Meanwhile, the rightful owners of Arab oil wealth, the masses crammed into the angry tenements of Baghdad, Cairo, Amman, and Khartoum, have little more to show for it than a trickle-down of oil-field jobs and Saudi-subsidized madrassas. While guests enjoy the $5,000 per night rooms in Burj Al-Arab, Dubai's celebrated sail-shaped hotel, working-class Cairenes riot in the streets over the unaffordable price of bread.

4. Can Markets Enfranchise the Poor?

Emissions optimists, of course, will smile at all the gloom-and-doom and evoke the coming miracle of carbon trading. What they discount is the real possibility that a sprawling carbon-offset market may emerge, just as predicted, yet produce only minimal improvement in the global carbon balance sheet, as long as there is no mechanism for enforcing real net reductions in fossil fuel use.

In popular discussions of emissions-rights trading systems, it is common to mistake the smokestacks for the trees. For example, the wealthy oil enclave of Abu Dhabi (like Dubai, a partner in the United Arab Emirates) brags that it has planted more than 130 million trees — each of which does its duty in absorbing carbon dioxide from the atmosphere. However, this artificial forest in the desert also consumes huge quantities of irrigation water produced, or recycled, from expensive desalination plants. The trees may allow Sheik Khalifa bin Zayed to wear a halo at international meetings, but the rude fact is that they are an energy-intensive beauty strip, like most of so-called green capitalism.

And, while we're at it, let's just ask: What if the buying and selling of carbon credits and pollution offsets fails to turn down the thermostat? What exactly will motivate governments and global industries then to join hands in a crusade to reduce emissions through regulation and taxation?

Kyoto-type climate diplomacy assumes that all the major actors, once they have accepted the science in the IPCC reports, will recognize an overriding common interest in gaining control over the runaway greenhouse effect. But global warming is not War of the Worlds, where invading Martians are dedicated to annihilating all of humanity without distinction. Climate change, instead, will initially produce dramatically unequal impacts across regions and social classes. It will reinforce, not diminish, geopolitical inequality and conflict.

As the United Nations Development Program emphasized in its report last year, global warming is above all a threat to the poor and the unborn, the "two constituencies with little or no political voice." Coordinated global action on their behalf thus presupposes either their revolutionary empowerment (a scenario not considered by the IPCC) or the transmutation of the self-interest of rich countries and classes into an enlightened "solidarity" without precedent in history. From a rational-actor perspective, the latter outcome only seems realistic if it can be shown that privileged groups possess no preferential "exit" option, that internationalist public opinion drives policymaking in key countries, and that greenhouse gas mitigation could be achieved without major sacrifices in upscale Northern Hemispheric standards of living — none of which seems highly likely.

And what if growing environmental and social turbulence, instead of galvanizing heroic innovation and international cooperation, simply drive elite publics into even more frenzied attempts to wall themselves off from the rest of humanity? Global mitigation, in this unexplored but not improbable scenario, would be tacitly abandoned (as, to some extent, it already has been) in favor of accelerated investment in selective adaptation for Earth's first-class passengers. We're talking here of the prospect of creating green and gated oases of permanent affluence on an otherwise stricken planet.

Of course, there will still be treaties, carbon credits, famine relief, humanitarian acrobatics, and perhaps the full-scale conversion of some European cities and small countries to alternative energy. But the shift to low, or zero, emission lifestyles would be almost unimaginably expensive. (In Britain, it currently costs $200,000 more to build a zero-carbon, "level 6″ eco-home than a standard unit of the same area.) And this will certainly become even more unimaginable after perhaps 2030, when the convergent impacts of climate change, peak oil, peak water, and an additional 1.5 billion people on the planet may begin to seriously throttle growth.

5. The North's Ecological Debt

The real question is this: Will rich counties ever mobilize the political will and economic resources to actually achieve IPCC targets or, for that matter, to help poorer countries adapt to the inevitable, already "committed" quotient of warming now working its way toward us through the slow circulation of the world ocean?

To be more vivid: Will the electorates of the wealthy nations shed their current bigotry and walled borders to admit refugees from predicted epicenters of drought and desertification like the Maghreb, Mexico, Ethiopia, and Pakistan? Will Americans, the most miserly people when measured by per capita foreign aid, be willing to tax themselves to help relocate the millions likely to be flooded out of densely settled, mega-delta regions like Bangladesh?

Market-oriented optimists, once again, will point to carbon offset programs like the Clean Development Mechanism which, they claim, will allow green capital to flow to the Third World. Most of the Third World, however, probably prefers for the First World to acknowledge the environmental mess it has created and take responsibility for cleaning it up. They rightly rail against the notion that the greatest burden of adjustment to the Anthropocene epoch should fall on those who have contributed least to carbon emissions and drawn the slightest benefits from 200 years of industrialization.

In a sobering study recently published in the Proceedings of the [U.S.] National Academy of Science, a research team has attempted to calculate the environmental costs of economic globalization since 1961 as expressed in deforestation, climate change, over-fishing, ozone depletion, mangrove conversion, and agricultural expansion. After making adjustments for relative cost burdens, they found that the richest countries, by their activities, had generated 42% of environmental degradation across the world, while shouldering only 3% of the resulting costs.

The radicals of the South will rightly point to another debt as well. For 30 years, cities in the developing world have grown at breakneck speed without any equivalent public investment in infrastructure services, housing, or public health. In large part this has been the result of foreign debts contracted by dictators, payments enforced by the International Monetary Fund, and public sectors wrecked by the World Bank's "structural adjustment" agreements.

This planetary deficit of opportunity and social justice is captured in the fact that more than one billion people, according to UN-Habitat, currently live in slums and that their number is expected to double by 2030. An equal number, or more, forage in the so-called informal sector (a first-world euphemism for mass unemployment). Sheer demographic momentum, meanwhile, will increase the world's urban population by 3 billion people over the next 40 years (90% of them in poor cities), and no one — absolutely no one — has a clue how a planet of slums, with growing food and energy crises, will accommodate their biological survival, much less their inevitable aspirations to basic happiness and dignity.

If this seems unduly apocalyptic, consider that most climate models project impacts that will uncannily reinforce the present geography of inequality. One of the pioneer analysts of the economics of global warming, Petersen Institute fellow William R. Cline, recently published a country-by-country study of the likely effects of climate change on agriculture by the later decades of this century. Even in the most optimistic simulations, the agricultural systems of Pakistan (a 20% decrease from current farm output predicted) and Northwestern India (a 30% decrease) are likely to be devastated, along with much of the Middle East, the Maghreb, the Sahel belt, Southern Africa, the Caribbean, and Mexico. Twenty-nine developing countries will lose 20% or more of their current farm output to global warming, while agriculture in the already rich north is likely to receive, on average, an 8% boost.

In light of such studies, the current ruthless competition between energy and food markets, amplified by international speculation in commodities and agricultural land, is only a modest portent of the chaos that could soon grow exponentially from the convergence of resource depletion, intractable inequality, and climate change. The real danger is that human solidarity itself, like a West Antarctic ice shelf, will suddenly fracture and shatter into a thousand shards.

California renews climate battle

New rules to curb emissions call for a 30 percent cut by 2020.
By Jim Downing - jdowning@sacbee.com
Published 12:15 am PDT Thursday, June 26, 2008

California's next great experiment starts today.

The state Air Resources Board will outline this morning a plan to slash greenhouse gas emissions 30 percent by 2020 and prepare the state for much deeper cuts in the years beyond.

The bottom line for consumers, according to the agency's analysis: Electricity and fuel prices will rise.

But improvements in efficiency should, on average, result in a net savings on household fuel and energy bills will drop.

"It's a plan that we believe will make our state more efficient in ways that will also help us grow," said Mary Nichols, chairman of the Air Resources Board.

The cuts to climate-warming emissions are required under Assembly Bill 32, a state law passed in 2006 that committed California to the nation's most aggressive global warming strategy. The air board's proposals are being watched closely around the country.

The release of the plan launches what is likely to be many months of haggling among state officials and dozens of environmental groups, utilities and businesses, including automakers, oil companies, appliance manufacturers and builders.

While the air board is required to adopt an outline of its emissions-cutting strategy by the end of the year, it has until the end of 2010 to finalize the policy details.

This week, both industry and environmental representatives expressed general support for the emissions-cutting plan – though rifts are already developing over parts of the plan industry groups say would dramatically drive up the cost of doing business.

"It takes away capital from what you want to do – including investing in ways to reduce greenhouse gas emissions," said Shelly Sullivan, executive director of the AB 32 Implementation Group, a coalition of businesses.

Jim Shetler, assistant general manager for energy supplies for the Sacramento Municipal Utility District, said the plan puts an undue burden on the electricity sector.

While power plants account for only 25 percent of the state's greenhouse gas emissions, the plan counts on energy suppliers to make 35 percent to 40 percent of the pollution reductions, he said.

"We are being asked to contribute more than we are imposing on the environment," Shetland said.

The air board's mission may already have been made easier by changes in the economy. Today's high energy prices are driving many of the sorts of emissions-cutting changes called for under the plan.

Sales of fuel-efficient cars are up, transit ridership is breaking records and businesses are investing in ways to save fuel and electricity.

But officials and energy experts say regulations are needed to keep those trends going should fuel prices drop. The new standards should also help drive investment in green technology, they said.

"The California plan will make the low-carbon energy market grow faster than it would on its own," said Bob Epstein, a venture capitalist who has advised the air board on the financial aspects of climate regulation. "When investors know there is going to be a regulatory limit on something, they can target that and not just wait until there's a price increase."

The core of the air board's plan – amounting to about 80 percent of the required cuts – is a suite of regulations, including some programs already under way.

Some of the biggest sources of emissions cuts:

• Electric utilities would by 2020 provide a third of their power from renewable sources like wind, solar and geothermal – compared with current levels of around 11 percent.

• Automakers would be required to curb emissions of greenhouse gases from new California vehicles more quickly than required under federal mileage standards – a proposal currently blocked by the Bush administration.

• The average energy efficiency of the state's buildings would improve by 25 percent through stricter rules on new construction and new efforts to retrofit existing structures.

To get the last 20 percent of the emissions cuts, the board has called for the creation of a market that would put a price on the right to produce greenhouse gases.

The "cap and trade" system, set to begin in 2012, would allow firms to buy and sell emissions permits. The state would control the volume of permits available, and ratchet down the supply over time. Economists say such a system should help minimize the overall cost of cutting emissions.

California is designing its trading rules to be consistent with those being developed by six other Western states and three Canadian provinces.

In the long run, the system may plug into a nationwide market, which Congress is considering.

Enlarging the trading market will benefit California industry by reducing the price of the greenhouse gas pollution credits and will reduce the chance of companies avoiding pollution control costs by relocating facilities to states without greenhouse gas limits, said Michael Gibbs, assistant secretary for climate change at the California Environmental Protection Agency.

Business and environmental groups disagree on key details of how the cap and trade system ought to work, such as whether the emissions permits should be auctioned off or given away for free.

Industry groups argue auctioning the permits amounts to a heavy tax that will hurt businesses and increase prices for consumers.

Environmental groups say granting the valuable credits amounts to a gift to industry.

"We don't think there's any justification for giving away any emissions credits to polluters," said Bill Magavern, director of Sierra Club California.

The air board, Nichols said, is trying to split the difference – auctioning only a few permits at first, and more in future years.

Climate change will likely have dramtic impacts on California flora and fauna




A paper by Duke and UCB scientists suggest that climate change will have negative effects on endemic plants and plant communities in California.

Another potentially catastrophic consequences of the fossil fuel addiction. While I think these studies are very important, there is too much uncertainty in the models to really characterize impact. For example, this study did not include any changes in the fog regime along coastal California. This is obviously an enormous variable as the fog and marine layer provide California with its cool and wet summer along the immediate coast, making life possible for numerous species including the coastal redwoods. That critique aside, these studies are important windows into possible future climate scenarios about how we should expect ecological systems to evolve over the next 100 years. Rather than test whether or not they pan out, we should tack this on to all the other negative consequences of our fossil fuel diet, and roll out the post-carbon economy.
