Wind Farms Cause Localized Temperature To Rise

Wind Farms Cause Localized Temperature To Rise

By Louise Gray / The Telegraph

Usually at night the air closer to the ground becomes colder when the sun goes down and the earth cools.

But on huge wind farms the motion of the turbines mixes the air higher in the atmosphere that is warmer, pushing up the overall temperature.

Satellite data over a large area in Texas, that is now covered by four of the world’s largest wind farms, found that over a decade the local temperature went up by almost 1C as more turbines are built.

This could have long term effects on wildlife living in the immediate areas of larger wind farms.

It could also affect regional weather patterns as warmer areas affect the formation of cloud and even wind speeds.

It is reported China is now erecting 36 wind turbines every day and Texas is the largest producer of wind power in the US.

Liming Zhou, Research Associate Professor at the Department of Atmospheric and Environmental Sciences at the University of New York, who led the study, said further research is needed into the affect of the new technology on the wider environment.

“Wind energy is among the world’s fastest growing sources of energy. The US wind industry has experienced a remarkably rapid expansion of capacity in recent years,” he said. “While converting wind’s kinetic energy into electricity, wind turbines modify surface-atmosphere exchanges and transfer of energy, momentum, mass and moisture within the atmosphere. These changes, if spatially large enough, might have noticeable impacts on local to regional weather and climate.”

The study, published in Nature, found a “significant warming trend” of up to 0.72C (1.37F) per decade, particularly at night-time, over wind farms relative to near-by non-wind-farm regions.

The team studied satellite data showing land surface temperature in west-central Texas.

“The spatial pattern of the warming resembles the geographic distribution of wind turbines and the year-to-year land surface temperature over wind farms shows a persistent upward trend from 2003 to 2011, consistent with the increasing number of operational wind turbines with time,” said Prof Zhou.

However Prof Zhou pointed out the most extreme changes were just at night and the overall changes may be smaller.

Also, it is much smaller than the estimated change caused by other factors such as man made global warming.

“Overall, the warming effect reported in this study is local and is small compared to the strong background year-to-year land surface temperature changes,” he added.

The study read: “Despite debates regarding the possible impacts of wind farms on regional to global scale weather and climate, modelling studies agree that they can significantly affect local scale meteorology.”

Professor Steven Sherwood, co-Director of the Climate Change Research Centre at the University of New South Wales, said the research was ‘pretty solid’.

“This makes sense, since at night the ground becomes much cooler than the air just a few hundred meters above the surface, and the wind farms generate gentle turbulence near the ground that causes these to mix together, thus the ground doesn’t get quite as cool. This same strategy is commonly used by fruit growers (who fly helicopters over the orchards rather than windmills) to combat early morning frosts.”

Book Review: Plan B 4.0: Mobilizing to Save Civilization

Book Review: Plan B 4.0: Mobilizing to Save Civilization

By Max Wilbert / Deep Green Resistance

Lester Brown’s exhaustively researched book, Plan B 4.0 – Mobilizing to Save Civilization, is a bold and impressive effort to chart a course to ecological sustainability, one of very few books that attempts this worthwhile goal. Brown lists 4 steps that Plan B 4.0 focuses on to achieve sustainability:

  1. Stabilize climate by cutting emissions by at least 80% by 2020
  2. Stabilize population at 8 billion or lower
  3. Eradicate poverty
  4. Restore natural earth systems (soil, aquifers, forests, grasslands, oceans)

These are excellent goals to begin with, and show that Brown is extremely serious about his mission, and is truly concerned about justice and the welfare of the human population. They also show that he understands one of the fundamental obstacles to true change – the interlocking relationship between environmental destruction and human exploitation. For example, Brown calls for debt relief for poor nations – an admirable position against the interests of international financiers and for the interests of poor and exploited people. Few analysts truly understand this relationship at both a theoretical and real-world level, and Brown moves beyond the average call for sustainability by acknowledging the seriousness of this issue.

Plan B lays out a compelling and comprehensive vision of the converging crises that are threatening life on earth – from oceanic collapse and peak oil to soil erosion and food instability. Brown understands that the collapse of global civilization is likely if business-as-usual continues. The undermining of the biological life-support systems of the earth has left life as we know it teetering on the brink. For many species and communities around the world, it is already too late.

The fundamental basis of Brown’s approach is that it is a social change approach. Brown understands that social problems require social solutions. While personal lifestyle changes (to transport, diet, and other consumption) are an important and moral way to address these problems, they are not sufficient to solve ecological and social injustice by themselves. This is an important step – a foundation for serious political work. From here, we can analyze each of the goals of Plan B 4.0 for strategic soundness, moral rigor, and good scholarship.

Step 1: Stabilize Climate

Brown’s approach to solving the climate problem relies on several strategies. First, he advocates massive adoption of alternative energy. Second, he calls for replanting of billions of trees to sequester carbon and rehabilitate habitat. Third, he describes an efficiency revolution centering on recycling, reusing, and refining urban planning and architecture and material flows throughout global society.

The focus on replanting of forests and restoring habitat around the world is extremely important and is an admirable goal, as is the elimination of coal and gasoline as energy sources. However, the fundamental failure of Brown’s approach to solving climate change is the insistence on maintaining an industrial way of life. Efficiency in cooking, housing, and production is doubtlessly important, but too many of Brown’s solutions call for centralized industrial production instead of local self-sufficiency – the maintenance of privileged lifestyles.

In short, while Brown’s plan is truly radical, he does not go far enough. In advocating massive production of solar panels, wind turbines, electric cars and trains, a “smart grid,” and other industrial technologies, Plan B 4.0 does not question the fundamental system of resource extraction and industrial production. It does not question global capitalism, which will continue to get rich by feeding on human and non-human communities.

The industrial products sold within the capitalist economy are created through a complex global system of mining, refining, production, distribution, and trashing/recycling. In each stage of this process, natural communities of humans and non-humans are exploited, poisoned, and destroyed for the sake of luxury goods like cars and electricity.

Electric cars and alternative energy do not address this fundamental destruction that is required for industrial technology to exist. Wind turbines, to use one example, still require mining for bauxite, the ore refined into aluminum. In central India (and other regions around the world) mountains containing bauxite are blown up and strip-mined to extract bauxite. About six tons of bauxite and a thousand tons of water a required to produce one ton of aluminum. There is no sustainable way to do this – most rich countries have exported this process to poor nations. The pollution is hidden.

This process not only destroys or displaces the non-human life on these mountains, but leads to runoff, pollution, and extirpation of indigenous communities. Smelting bauxite requires extremely high temperatures – usually provided by big dams – and leads to vast amounts of carbon emissions and other air pollution. And the entire system of distribution depends on vast ocean-going ships that burn bunker fuel, one of the dirtiest fossil fuels. It is estimated that one container ship releases as much carbon dioxide as 50 million cars.

Another example: the Toyota Prius, widely praised by environmentalists (including Brown), requires 5 times as much energy to produce as an average car due to the complex process of creating electric motors, circuitry, and batteries. Accounting for production energy and transportation fuel and average over the lifetime of the car, a Prius actually uses 1.4x as much energy per mile as the average American car.

Solar panels provide another example. The average solar cell requires the mining of about 2,000lbs of earth material for Silicon. The production process is extremely dangerous – in China, workers at a solar panel factory went on strike in 2011 because of the pollution released by the plant had toxified a lake nearby that was causing respiratory problems and cancers in the community.

This is just touching the surface of the devastation that is wrought by these “environmentally friendly” technologies. These technologies also require rare earth minerals like cadmium and tellurium, which simply do not exist in sufficient quantities to allow mass adoption of alternative energy.

This reliance on technological solutions is one the major failings of Plan B 4.0. Brown has bought into the hype surrounding these alternative technologies, when in reality they only represent more of the same – more resources extracted from poor nations, more money flowing to corporations and rich nations, more pollution, more destroyed communities. While the standards of research and scholarship in Plan B 4.0 are generally very high, Brown does not apply the same rigorous research methods to the technological solutions he advocates.

A better model for halting global warming would revolve around the creation of land-based communities that are able to take their sustenance from within healthy, flourishing ecosystems that they coexist with. This model is the way of life practiced by humans for 99% of our existence, so it is clearly not impossible, but it would require addressing the serious issue of population, to which Brown turns next.

Step 2: Stabilize Population

In addressing overpopulation Brown is facing an issue before which many have balked, with good reason. There is a history of racism, eugenics, and forced sterilization that makes population reduction a touchy issue to deal with directly.  But Plan B 4.0 takes the right tact. Brown’s plan calls for massive programs of education and empowerment of women, combined with government incentives for small families, widespread family planning programs, and universal birth control availability. This humane and effective model has been used around the world in places like Iran with great success.

While this approach is laudable, Plan B 4.0 could use a slightly more radical feminist analysis. While Brown does call for the education of women, he does not explicitly state that empowered women rarely chose to have large numbers of children. High birth rates usually occur in patriarchal arrangements where women have few rights and little power of their own. Acknowledging this fact and working to dismantle patriarchal social forms will be a much more difficult task than the more straightforward path that Brown presents, but will lead to more lasting and fundamental change in birth rates and the overall direction of society.

Step 3: Eradicate Poverty

By acknowledging the fundamental connections between global poverty and environmental degradation, Brown goes further towards truth than many of his contemporaries. He advocates for debt relief for poor nations, which would go a long way towards relieving the pressures on “developing” nations. He calls for an increase in small gardens and other simple techniques that reduce burdens on poor people around the world, planting forests and allowing degraded lands to fallow.

However, without access to land, poor people have no chance for survival. The critique of contemporary land grabs is an important part of Plan B 4.0. Here Brown details how food importers, nations that cannot grow enough food to support their population, are purchasing and leasing arable land in poor nations to grow food for export. Many times these poor nations cannot even feed their own population, so these vast foreign-held farms must employ armed guards to ensure that the food is not taken back.

Brown understands that agriculture, logging, and overgrazing are devastating much of the land around the world through salinization, soil erosion, and desertification, and that this process is destabilizing populations and leading to poverty and social breakdown.

However, Brown is lacking a fundamental critique of industrial agriculture as a practice. He advocates the use of pesticides and fertilizers, which are overwhelmingly toxic and derived from fossil fuels. He advocates for increased efficiency in irrigation, while acknowledging the fact that 70% of the fresh water used worldwide is used for irrigation. And he advocates for the use of genetically modified and high-yield varieties, which is a gamble with the genetic code. This is also leading to a narrow range of varieties, which are more vulnerable to future disease of plague. The result has been an arms-race between GMO and pesticide companies and the constantly evolving creatures that feed on monocropped fields.

Even more fundamentally, Brown does not appreciate the fact that annual monocrop agriculture is the practice that has enabled rampant overpopulation. Population tracks food supply, and it has been well documented is recent years that many creatures (including humans) regulate their own population based on the food available. When humans began farming the land and stopped getting their food from within biodiverse, perennial ecosystems, they stopped paying attention to these natural limits. They were not sharing their food anymore.

This lack of sharing is also the foundation of modern ecological devastation. After all, agriculture is the practice of clearing natural ecosystems and replanting them for human use. The forests and grasslands that have fallen before the plow are the primary location for species loss worldwide. Ninety-eight percent of old-growth forests and 99% of native grasslands are gone. Human population has grown in direct proportion to the decline in non-human populations worldwide, because they have been consumed by civilization, by agriculture.

Brown’s failure here is the same as above – he has no fundamental critique of capitalism (the dominant economic system) and civilization (the dominant form of social organization – a way of life based on annual monocrops and life in cities). These systems are a major reason why people are poor.

By extracting resources in destructive ways and exploiting workers for less than the full value of their labor, capitalism impoverishes people around the world. A large class of poor people is required for the functioning of the global economy – it is structurally mandated. And civilization is a social form that inevitably leads to overshoot of natural limits, colonial expansion, wars of conquest, further environmental damage, and finally collapse (for a further explanation of these ideas, see Sources). Any efforts to address poverty will have to first deal with the stifling influence of capitalism and civilization.

Step 4: Restoring Earth

The final goal of Plan B 4.0 is to restore natural ecosystems around the world – oceans, grasslands, soils, and forests. In order to protect biodiversity and the range or natural services provided by these ecosystems, Brown advocates massive replanting of forests (as previously mentioned), soil conservation measures, and the creation of protected marine zones in the ocean, as well as a program of parks and other measures to protect biodiversity.

Replanting forests is an important way to restore the life-support systems of the planet, and Brown is the right advocate for it. However, he also advocates for an increase in plantation style forests to be grown for timber and pulp products. While the US Forest Service is a division of the Department of Agriculture, forests are not fields, and few soils can sustain more than three consecutive harvests of timber before soils are too depleted to continue. An imposition of human standards upon a natural system decreases the health of the system, and as such, plantations are not a long-term solution.

Restoring soils is perhaps the most critical task in this section. Terrestrial life as we know it is only possible because of a thin layer of topsoil – without it, plants cannot grow. Brown’s tactic of allowing steeper slopes and other marginal farmland to fallow and return to forest is a good one, but he still lacks a full critique of agriculture as a practice. Annual monocropped fields lead to erosion and loss of soil fertility – this type of agriculture kills the soil. This is true around the world, except in small river valley regions where alluvial soils are constantly replenished.

However, these natural wetlands are also biodiversity hotspots, which means the one place where agriculture can be practiced somewhat sustainably is also the place where it will lead to the biggest loss of habitat for other creatures. Brown’s plan for protecting biodiversity is not elaborate – there are almost no details in the book. But any course of action that does not challenge the human appropriation, destruction, and toxification of land, water, and atmosphere will not lead to substantial progress in the conservation of biodiversity.

Conclusion

Plan B 4.0 is a unflinching attempt to chart a course for sanity, but Lester Brown and his researchers fail to apply the same rigor to human society and proposed solutions that they apply to environmental problems. Brown states that in 1950 the world economy was based on “sustainable yield, the interest of natural systems.” This is simply not true. Europe was deforested before industrialization. So was the Middle East. The forests and soils of North Africa fueled the Roman war machine until they were exhausted, and now support only goats and olives – ecological poverty food that can survive on desiccated, impoverished soils. The forests of the United States were felled largely before the mechanical saw. While industrialism greatly accelerated in the 1950’s, the problem goes much deeper than that.

Brown’s approach, along with the approach of many other environmentalists, is fundamentally anthropocentric and short sighted. He does not account for the experience of prehistory, that span of 99.7% of human existence when the natural world flourished alongside us. He does not even mention indigenous people, the only communities that have truly lived in a sustainable manner. Any understanding of environmental sustainability must advance from the basic position that humans have the ability to coexist with the natural world. These model societies exist, but they are being destroyed by the very industrialism that Brown supports with his calls for alternative technology (for example, the Dongriah Kondh of the central Indian foothills).

Instead of exploring how human societies may better conform themselves to the needs of the land, Brown falls into the trap of reform – how can we adapt nature to better fit our needs? How can we maintain the energy grid, industrial production, a high population, and the conveniences of globalized capitalist civilization while simultaneously addressing environmental problems? The fundamental answer to this question is that such a solution is not possible. In failing to see this point, Plan B 4.0 stumbles and falls along with the vast majority of the environmental movement.

Lobbyists for palm oil industry try to reverse EPA decision against carbon-intensive biodiesel

By Mongabay

Wilmar International, the world’s largest palm oil processor and trader, has hired a major lobbying firm to overturn the Environmental Protection Agency’s ruling that palm oil-based biodiesel will not meet greenhouse gas emissions standards under America’s Renewable Fuels Standard, reports The Hill.

Wilmar Oleo North America hired lobbying firm Van Ness Feldman to pressure the EPA on its finding that biofuels produced from palm oil do not offer substantial emissions savings relative to conventional gasoline. The EPA based its decision on analysis of lifecycle emissions from palm oil production, which at times occurs at the expense of carbon-dense rainforests and peatlands.

The Hill notes that the American Legislative Exchange Council (ALEC), a conservative group that drafts legislative language favoring corporate interests that fund it, is working to overturn the EPA’s finding.

“The Environmental Protection Agency’s decision to restrict the trade of tropical palm oil marks an abandonment of free trade principles that have been so beneficial to so many,” the group said in comments submitted to the EPA.

Malaysian and Indonesian groups have also complained about the EPA’s ruling. The period for comment on the matter closes April 27.

But environmental groups said the assumptions underlying the EPA’s conclusion were too conservative, noting that the agency expects only nine percent of palm oil expansion in Malaysia and 13 percent in Indonesia to occur on peatlands. But a study published today in the National Academy of Sciences, found that half of oil palm plantations in Indonesian Borneo were established on peat lands. Conversions of peat for plantations generates substantial greenhouse gas emissions.

“It is a disturbing development to see a politically motivated group like ALEC join forces with the shadowy palm oil lobby from Malaysia and Indonesia as well as with huge agribusiness companies Cargill and Wilmar to pressure the EPA to overturn what is supposed to be a science-based decision made in the best interests of the American people,” said Laurel Sutherlin with the Rainforest Action Network, in a statement. “The question the EPA is tasked with answering is whether biofuels made with palm oil meet our nation’s greenhouse gas requirements as a renewable fuel. The stark reality of the impacts of palm oil plantation expansion in Southeast Asia, where nearly 90% of the world’s palm oil comes from, makes it clear that it does not.”

“The emissions of palm oil based biofuels substantially exceed the emissions from conventional petroleum diesel,” added Jeremy Martin, Senior Scientist at the Union of Concerned Scientists.

The renewable fuels standard targets 7.5 billion gallons of ‘renewable’ fuels to be blended into gasoline by the end of 2012. The initiative aims to reduce dependence on foreign oil and cut emissions from transportation, but some analysts have questioned the effectiveness of the program, since the bulk of ‘renewable’ fuel is expected to come from corn ethanol, which environmentalists say has mixed climate benefits.

Oil corporation Perenco endangering lives of “uncontacted” indigenous people in Peru

By David Hill / Mongabay

The company hoping to exploit the oil deposits slated to transform Peru’s economy has been declared to be endangering the lives of indigenous people living in “voluntary isolation” by the country’s indigenous affairs department (INDEPA).

Perenco, an Anglo-French company with headquarters in London and Paris, is currently seeking approval from Peru’s Energy Ministry (MEM) to develop its operations in the Loreto region in the north of the country.

MEM has already blocked Perenco once this year by refusing to approve the Environmental Impact Assessment (EIA) of the next stage of its operations. One of the reasons given was the company’s failure to obtain INDEPA’s “technical opinion” on its EIA.

That opinion, expressed in a seven page report, was forthcoming on 20 February and sent by MEM to Benoit de la Fouchardiere, Perenco’s general manager in Peru, on 5 March.

Perenco fails to acknowledge “the total superimposition of Lot 67A and Lot 67B by a proposal to create a reserve for indigenous people who live in voluntary isolation,” INDEPA says.

“This is concerning, given that the exclusion of this proposed reserve doesn’t allow for the identification of the possible negative social and environmental impacts of the project on the isolated people who live there.”

INDEPA is especially critical of Perenco’s Anthropological Contingency Plan, which it says denies the existence of the “isolated” people and thereby increases their vulnerability if contact with them is made.

“No measures to prevent the transmission of illnesses or epidemics are considered, as they should be according to regulations and technical health guides about indigenous people in isolation or initial contact,” it says.

INDEPA’s report is potentially embarrassing for Perenco because it has repeatedly claimed there are no “voluntarily isolated,” or “uncontacted,” people in the region where it is operating. Its Latin American regional manager once compared them to the UK’s Loch Ness monster, declaring, “Much talk but never any evidence.”

While media focuses on Keystone XL, Canadian energy companies make a killing in Latin America

By Dawn Paley / The Dominion

The hard fought battle against the Keystone XL pipeline, which was slated to carry tar sands crude across Canada and the United States to port in Texas, kicked struggles against Canadian-owned oil and gas companies up to a new level. Resistance dominated headlines in Canada, while rural folk, Indigenous people, celebrities, and climate activists in the US took direct action to block Calgary-based TransCanada’s plans. In northern BC, Indigenous-led resistance to the proposed Enbridge pipeline, along with a host of other US-owned infrastructure projects, have become front and centre issues for environmentalists and activists across Canada.

The role of Canadian oil, gas and pipeline companies in other parts of the world is, however, less discussed. Many activists have focused on the behavior of the Canadian mining sector, a natural choice given the size of that sector compared to the oil and gas industries in Canada. “In Canada, a major difference between the oil and gas and mining sectors is that while many of Canada’s largest companies are oil and gas producers, some with integrated operations, they are not particularly prominent in the global arena just now,” reads a 2008 report by the Economic Commission on Latin America.

It’s been four years since that report was released, and it might be time to revisit the idea that the Canadian oil and gas sector hasn’t gained prominence on a global scale. Take the case of Latin America, where a host of oil and gas companies based in Calgary and Toronto have been increasing their holdings throughout the hemisphere, taking advantage of the same lax legal standards Canadian mining companies enjoy.

A study by Blake, Cassels & Graydon LLP found that in 2010, Canadian oil and gas companies made over $35 billion in mergers and acquisitions in Central and Latin America, and the region is the second most attractive place (after the United States) for Canadian oil companies to invest outside of Canada. Colombia in particular has quickly become a favourite destination for this new surge of Canadian oil and gas investment.

At the same time as the Canadian Senate approved a free trade agreement between Canada and Colombia in June of 2010, a government-hosted bidding fair on oil and gas properties was taking place in Cartagena, Colombia. “I have some good news for our Canadian friends. The Senate has just approved a free trade agreement…so that opens the way for a lot of opportunities and our government is very happy about that,” said then-Colombian Energy and Mining Minister Hernan Martinez to corporate representatives bidding on oil and gas concessions in Cartagena that day.

Canadian oil companies were among the chief supporters of the agreement, which was roundly criticized because of the continued killings, kidnapping and displacement of Indigenous people, trade unionists, peasants, dissenters and the poor in Colombia. A free trade agreement with Peru was approved by the Canadian Senate a little later, on the heels of a massacre in the Amazon province of Bagua where an estimated 100 people were killed during protests in defense of their lands.

Pacific Rubiales and Talisman, two of the most important Canadian oil companies in Colombia, have already come under intense criticism linked to the high environmental and social cost of their operations.
