Brazil’s increase in fires in Amazon region – alarming news
The alarming number of fires in the Brazilian Amazon, Mongabay, 8 September 2016 / Commentary by Natália Girão Rodrigues de Mello
For three months, from September to December 2015, Manaus was engulfed in smoke, resembling Beijing. That was an unusual scene, and an undeniable sign that predatory exploration in the Brazilian Amazon has not yet been properly tackled.
- The sharp decrease in the annual rates of forest loss in the Brazilian Amazon is celebrated worldwide. The trend started in 2005 after a peak in deforestation the year before.
- However, the figures are not so bright when it comes to forest fires, and few people are talking about that.
- The number of fires in the Brazilian Amazon is alarming, and that was especially true in 2015, when a sharp increase in forest fires occurred………
- Natural factors alone fail to explain this recent increase, as similar climatic conditions in the past were not associated with the same amount of forest fires.
Forest fires and precipitation are strongly correlated in the Brazilian Amazon; in dry years, more forest fires occur. 2015 was a dry year, but not as dry as 2010 or 2005 were – years when the region faced anomalous droughts. Nevertheless, in 2015, forest fires increased 115.6 percent and 105.5 percent compared to 2005 and 2010, respectively. Hence it is safe to say that the peak observed last year was strongly associated with unregulated anthropogenic activities in the forest.
In the region, using fire in order to clear large areas is a common practice. The expansion of roads, settlements, croplands and cattle ranches has been leading fires to reach ever-wider areas of the forest.
The consequences associated with this issue are vast. They are felt locally, regionally and globally. Forest fires contribute to climate change due to the emission of three greenhouse gases: carbon dioxide, methane, and nitrous oxide. As the forest burns, health-damaging gases – carbon monoxide, non-methane hydrocarbons, methyl chloride, and methyl bromide – are also emitted, as well as volatile organic compounds (VOCs) and aerosols. VOCs interact with nitrous oxides to form ozone, a phytotoxic gas. Aerosols cause the suppression of cloud formation and the decrease of precipitation efficiency. Moreover, a positive feedback between fire-induced death of trees and increased solar penetration in the forest occurs, resulting in the intensification of successive fires…….https://news.mongabay.com/2016/09/the-alarming-number-of-fires-in-the-brazilian-amazon/?utm_content=buffer4318b&utm_medium=social&utm_source=twitter.com&utm_campaign=buffer
If Amazon forest catches fire, world climate will be in even bigger trouble
Researchers are increasingly concerned that the Amazon rain forest — the world’s largest tropical forest, a huge repository of carbon and a vital cycler of water into rainfall across much of South America — will soon burn in a way that has not been seen in many years.
The reason is the lingering effect of the recent El Nino event. Forecasts from NASA and the University of California-Irvine, and from the International Research Institute for Climate and Society suggest that because of how El Nino reduced precipitation in the region earlier this year, the Amazon is far drier than usual, and primed to burn once the dry season reaches its height this summer (the fire season runs from June through November with a September peak).
According to the NASA/U.C. Irvine forecast, the Amazon is currently “far drier than 2005 and 2010 — the last years when the region experienced drought.” The years 2005 and 2010 also saw major blazes in the Amazon.
Indeed, the NASA/U.C. Irvine researchers shared data suggesting that the storage of water in the Amazon in March of 2016, as measured by NASA’s twin GRACE satellites (which detect gravitational anomalies at the Earth’s surface), is far lower now than it was in March during these prior years.
“We have the possibility of killing hundreds of thousands of trees in the Amazon in 2016, if you let these fires start,” says Paulo Brando, an Amazon fire expert at the Woods Hole Research Center and Ipam (the Amazon Environmental Research Institute).
If these forecasts are verified, there will be a great deal at stake. It isn’t just that huge, dangerous clouds of smoke could reach major urban areas ranging from Manaus to Rio. It’s that the fires risk helping to tip the Amazon into a new state that scientists fear — one in which it will be drier, store less carbon, cycle less water and generate less rainfall.
That would be disastrous for the Earth’s climate overall. The Amazon alone stores an enormous amount of carbon, 120 billion tons worth. Put that stuff in the atmosphere and the result would be justly termed catastrophic………
It is important to note that so far, what we are looking at are bad fire forecasts for this summer in the Amazon — but not a catastrophe at this point. The forecasts may not be realized. (That happens!) And the forecasts could also drive at least some action in Brazil and other Amazon countries to take steps to prevent people from starting fires, blunting the potential consequences of drought.
That’s the good news. The bad news is that scientists continue to talk about the Amazon in the same way they talk about, say, West Antarctica or the overturning circulation of the Atlantic Ocean — as a delicate system that we could tip, with enormous consequences. https://www.washingtonpost.com/news/energy-environment/wp/2016/07/12/the-ultimate-forest-fire-whatll-happen-when-the-amazon-burns/
Tropical countries need solar power, more than free cooling
Tropical sites need solar power, not free cooling, Data Center Dynamics 24 March 2016 By Paulo Cesar de Resende Pereira Free cooling can improve some measures of efficiency, but tropical countries may be better off looking at where their power comes from
The importance of data centers to the average citizen should not be underestimated. They are vital for even the most common daily function – from a simple internet search to a bank transaction. Their importance can even extend to, for example, the monitoring of the electricity delivered to one’s home.
But data centers are accused of being environmental villains due to their exorbitant consumption of energy, so reducing their environmental impact is vital. In this context, photovoltaic generation is an interesting alternative to free cooling, and especially suitable for tropical regions such as Brazil.
Using the wrong metricEcological footprint (ecofootprint), according to WWF Global, is connected to the impact of human activities, measured according to the production area and the amount of water needed to produce goods and assimilate the waste produced.
Data center efficiency is usually rated by PUE, a parameter conceptualized by the US, the EU and Japan to establish a single metric to assess the energy efficiency of data centers. The concept is not new, because the relationship between useful energy and invested energy is used in many other processes.
The calculation of this indicator is based on the relationship between the energy consumption by the installation as a whole (total energy) and the energy consumption exclusively by IT equipment (IT energy). Like any indicator, PUE may be called into question, but it remains a useful metric nonetheless.
It did not take long for the cooling system to be considered the greatest enemy of PUE; as a consequence, its efficiency has become closely related to its reduction. There is nothing more tempting than getting something for free; for instance, a data center that could potentially be cooled by nothing more than the forces of nature. Since this is not possible, the solution is to decrease a good percentage of energy consumed by central chilled water, taking advantage of free cooling, thus decreasing PUE………
Free energy, not free coolingThe concept of free energy emerges as an alternative to free cooling, on the grounds that it is more suitable to the Brazilian reality and to other countries with similar weather. It is related to power generation using any renewable energy source that has been obtained directly from nature through an environmentally sustainable process. This solution, as well as free cooling, aims to improve data center effectiveness and reduce the ecofootprint from data centers in general. Because of the distributed generation and the ability of interaction between the minigeneration and the energy provider, free energy has become a feasible concept.
Taking photovoltaic power as an example of free energy, when data centers are transformed into generation plants, they may apply this energy to the grid and offset it – not only from an energy standpoint but also economic. Once the concept of free energy is settled, it is inserted into another new term – EcoPUE – bringing a new idea for calculating PUE that is now even more environmentally friendly and presents a sustainable aspect, where the reduction of energy consumption in the data center is linked to the subtraction of the energy generated by the photovoltaic generation system. This renewable generated energy is called ‘free energy.’
Use what works
The increased demand for processing and storage of data, together with the environmental problems caused by high energy consumption, are forcing data centers in Brazil, and elsewhere, to seek more technological solutions and become increasingly green, using energy more efficiently and sustainably while providing a quality service to customers
. A combination of existing technology and techniques, along with new government legislation in Brazil, are now in place, so significant improvements have already been achieved. As an alternative to free cooling, the use of photovoltaics is increasingly being seen as a viable option in countries with a high solar radiation index – like Brazil – where renewable energy can be obtained for free from the natural resources available on the planet.
The concept of EcoPUE demonstrates that greater efficiency from a data center can be enforced with the use of photovoltaic generation, thus reducing their environmental footprint.

Corruption and mismanagement stall Brazil’s nuclear programme
Turbulent Times for Brazil’s Nuclear Projects, Carnegie Foundation, TOGZHAN KASSENOVA October 29, 2015 “……….Othon was at the heart of Brazil’s nuclear program during the military government that lasted until 1985, and he remained indispensable for the decades that followed. In 2005, he became the chief executive of Eletronuclear, an operator of nuclear power plants and a subsidiary of Eletrobras, a state-controlled power company. Eletronuclear operates Brazil’s two nuclear power plants—Angra 1 and Angra 2—and is building a third plant in the picturesque region of Angra dos Reis, not far from Rio de Janeiro. Work on Angra 3 began in 1984. But after two years and the amassing of 70 percent of the equipment at the site, construction was suspended. Only after twenty-four years, in 2010, did construction resume on Angra 3.
The corruption charges against Othon stemmed from the construction of Angra 3. It was while he headed Eletronuclear that Othon was accused of receiving bribes from companies vying for Eletronuclear’s contracts. He was arrested on July 28 as part of an operation called Radioactivity, the sixteenth stage in Operation Car Wash.
Othon is currently accused of receiving 4.8 million Brazilian reais (or approximately $1.2 million) in bribes through Aratec Engenharia, a company he owned. Brazilian media report that Othon’s company accepted payments for the development of turbines that generate electricity using river flow.
Othon’s arrest is not the only nuclear dimension of Brazil’s corruption scandal. Marcelo Odebrecht, whose eponymous company is Brazil’s largest construction conglomerate, was arrested on corruption charges in June. His company is accused of paying bribes to Petrobras executives to gain lucrative contracts, overcharging Petrobras for construction projects, and siphoning off illegal profits to politicians who, in turn, facilitated the conglomerate’s operations.
Odebrecht is one of the largest companies in South America. With operations in 21 countries and a workforce of 168,000, the equivalent of the population of a medium-sized U.S. city, it has been involved in major infrastructure projects in places as diverse as Saudi Arabia and Angola.
Odebrecht is the main contractor for Brazil’s nuclear submarine program. In 2009, when Brazil and France signed a cooperation agreement to build five submarines—four conventional and one nuclear—together, Odebrecht received a contract worth $1.9 billion to construct a new naval shipyard in Itaguaí. In 2013, Brazil’s then president Dilma Rousseff attended the shipyard’s inauguration ceremony. With Odebrecht’s CEO under arrest, the immediate future of the company is uncertain.
Brazil’s Nuclear Ambitions ………..
Funding was pouring steadily into the nuclear submarine program. Since 2009, Brazil has spent $3.2 billion to build a submarine shipyard and a naval base. Brazil’s leaders promoted the program as one that would once again prove Brazil’s technological might—just as Embraer planes did decades earlier.
In 2010, construction of the Angra 3 nuclear power plant resumed, and while the government never touted nuclear energy as its priority, commitments were made to build up to four to eight new nuclear power plants.
Five years later, a very different Brazil has emerged. Foreign policy, let alone nuclear diplomacy, has decreased significantly on the ladder of Brazilian government priorities. Unlike Lula, President Dilma from the very beginning was less inclined to invest in an active foreign policy. Now she is too preoccupied with domestic problems to spend time on diplomacy. With her approval ratings hovering at 8 percent, foreign policy is unlikely to become a priority for the current government in the near future. The possibility that the government will actively pay attention to matters of global nuclear politics is even less likely.
Former head of Brazil’s nuclear company will face trial
Judge accepts charges filed against former head of Brazil nuclear power firm Fox News, 3 Sept 15 SAO PAULO – A federal judge Thursday accepted the charges filed by prosecutors against the former head of Eletronuclear, the state-owned company that operates Brazil’s two nuclear power plants, for his suspected role in a bribery scandal.
Othon Luiz Pinheiro da Silva will face trial for allegedly taking 4.5 million reals ($1.22 million) in bribes from construction companies for contracts involving the construction of the Angra 3 nuclear plant in Rio de Janeiro.
Judge Sergio Fernando Moro said in a statement that he also accepted the charges filed against 14 others, including Flavio David Barra, the top energy executive at construction firm Andrade Gutierrez and da Silva’s daughter, Ana Cristina Toniolo…….http://www.foxnews.com/world/2015/09/03/judge-accepts-charges-filed-against-former-head-brazil-nuclear-power-firm/
Police asks prosecutors to charge former head of Brazil’s nuclear power on corruption
Police ask that charges be filed against former head of Brazil’s nuclear power company http://www.foxbusiness.com/markets/2015/08/28/police-ask-that-charges-be-filed-against-former-head-brazil-nuclear-power/ SAO PAULO – Police say they have asked prosecutors to file charges against the former head of Eletronuclear, the state-owned company that operates Brazil’s two nuclear power plants, for his suspected role in a bribery scandal.
A federal police spokesman who was not authorized to be quoted by name said late Thursday that the department wants prosecutors to charge Othon Luiz Pinheiro da Silva with money laundering and corruption for allegedly taking as much as $10 million in bribes from construction companies for contracts involving the construction of the Angra 3 nuclear plant in Rio de Janeiro.
Da Silva was taken into custody in late July and one week later stepped down as Eletronuclear’s chief executive officer.
The spokesman said the department also wants charges filed against Flavio David Barra, the top energy executive at construction firm Andrade Gutierrez and da Silva’s daughter Ana Cristina Toniolo for their suspected roles in the scheme. Da Silva, his daughter and Barra have denied any wrongdoing.
During Brazil’s military regime from 1964-1985, the retired navy admiral and nuclear engineer headed Brazil’s secret program to master the technology needed to transform uranium into fuel to generate electric power in nuclear plants. Da Silva also oversaw the ongoing project to build a nuclear powered submarine.
The request for charges to be filed come as police and prosecutors try to determine whether a kickback scheme engulfing state-run oil company Petrobras extends to other state firms, including electric utilities company Eletrobras, of which Eletronuclear is a subsidiary.
Prosecutors have said the scheme involved roughly $2 billion in bribes and other illegal funds. Some of that money was allegedly funneled back to the ruling Workers’ Party and its allies’ campaign coffers. It also allegedly included the payment of bribes to Petrobras executives in return for inflated contracts.
For Alexandre Barros, a political risk consultant with the Brasilia-based firm Early Warning, the Eletronuclear case shows that Petrobras-like corruption and kickback schemes are “probably present in other state-run companies.”
“Schemes like these have long been part of our culture and I think other similar schemes start emerging all over the place”, Barros said “My big fear is that the armed forces may start feeling uneasy,” he added, without elaborating.
Corruption scandal may halt Brazil’s nuclear power programme
Ildo Sauer, a nuclear physicist who worked under Pinheiro in the late 1980s, says Brazil’s nuclear program is too expensive and has been co-opted by politicians and major construction and engineering firms.
“The problem is the lobbyists who see nuclear as a chance to build expensive megaprojects with little regard for cost,” said Sauer, a former head of natural gas at Petrobras. “It’s no longer about science or energy. It’s about politics and money, and that brings corruption.
Brazil Nuclear Leader’s Arrest May Stymie Atomic Ambitions Reuters, VOA, July 30, 2015 RIO DE JANEIRO— The arrest of the longtime head of Brazil’s nuclear energy utility on corruption charges could disrupt a plan to revive Brazilian nuclear ambitions whose roots go back to its atomic-bomb program in the 1980s.

Brazil cools on nuclear power plans; favors wind
Brazil will probably scale down its plans for new nuclear plants due to safety concerns following the 2011 radiation leak in Japan and pick up some of the slack with a “revolution” in wind power, the head of the government’s energy planning agency said.

Brazil’s wind farms bring cheapest electricity prices
Wind farms set record low generation prices, SMH, December 16, 2012 Four energy developers agreed to sell power from 10 proposed wind farms in Brazil at the cheapest rates ever.
Enerfin Sociedad de Energia SA, Renova Energia SA, EGP- Serra Azul and Bioenergy Geradora de Energia Ltda. won contracts to sell electricity to distributors for an average price of 87.94 reais ($41) a megawatt-hour, Brazil’s national energy agency Empresa de Pesquisa Energetica said in an e-mail yesterday. (Australian wholesale prices are about $50 per megawatt-hour, including the $23 carbon tax per tonne.)
“This is definitely the cheapest wind energy in the world,” Maria Gabriela da Rocha Oliveira, a Sao Paulo-based analyst with Bloomberg New Energy Finance, said in a telephone interview. It’s 12 per cent lower than the August 2011 auction that yielded an average price of 99.58 reais a megawatt-hour. That was the lowest price in the world for wind power then and the least expensive power in Brazil, beating natural gas and hydroelectricity….. http://www.smh.com.au/business/carbon-economy/wind-farms-set-record-low-generation-prices-20121216-2bh4z.html#ixzz2FLfka1Ga
Areas of naturally high radiation have also higher cancer rates
2004 Study: Two of Brazil’s High Background Radiation Areas Have Higher Cancer Mortality Via : http://ex-skf.blogspot.com.au/2012/04/2004-study-two-of-brazils-high.html quote: APRIL 14, 2012
I have been told numerous times that “People in naturally high background radiation areas in the world suffer no ill effect from the high radiation.” I just stumbled upon one study in 2004 on such areas in Brazil.
Conclusion of this particular study: Cancer mortality in “Poços de Caldas, and Guarapari is higher than would be expected for their respective reference population”, whereas “cancer mortality for the Araxá population is lower than would be expected”.

Brazil ditches nuclear reactor plans, in favour of renewable energy and gas
Brazil shelves plans to build new nuclear plants Google News 10 May (AFP) BRASILIA — Brazil said Wednesday it has shelved plans to build new nuclear power stations in the coming years in the wake of last year’s Fukushima disaster in Japan.
The previous government led by former president Luiz Inacio Lula da Silva had planned to construct between four and eight new nuclear plants through 2030….. “The last plan, which runs through 2020, does not envisage any (new) nuclear power station because there is no need for it. Demand is met with hydro-electrical power and complementary energy sources such as wind, thermal and natural gas,” Energy ministry’s executive secretary, Marcio Zimmermann said in remarks released by the ministry Wednesday. “The 2021 plan, as far as I know, will not consider nuclear power stations either, ” he added, ….
Brazil postpones its nuclear power project
Brazil delays nuclear plans after Japan disaster RIO DE JANEIRO (MarketWatch) Feb. 8, 2012, — Brazil’s plans to build four new nuclear power plants have been delayed by about 18 months following last year’s accident at the Fukushima Daiichi nuclear plant in Japan, an official of Brazilian state-owned nuclear power company Eletronuclear said Wednesday….
Brazil’s nuclear plans a cash cow for France and a weapons worry
Brazil’s nuclear plans stir up debate, RIO DE JANEIRO, Nov. 30 
(UPI) — Brazil’s nuclear program, including its ambitious moves to develop a nuclear-powered submarine with French help, is stirring debate that puts focus on the Latin American country’s long-term aims in the field.
Both Brazil and Argentina began developing nuclear capabilities while under military rule. While Argentina has expanded its nuclear power generation capacity Brazil has gone into nuclear fuel processing and hopes to deploy the technology into a nuclear-powered submarine it plans to build with French help.
Agreements for the joint defense production program are in place but, as the implementation nears, questions are being asked about its nuclear component. French President Nicolas Sarkozy spearheaded a marketing drive that secured France much needed cash in a deal that includes the supply and joint construction of four diesel-electric submarines and a fifth nuclear-powered submarine….. Brazil has an advanced nuclear program dating to the 1950s that has drawn support at various stages from France, Germany and the United States. ….
Brazilian analysts who disagree with the nuclear bomb thesis say a program that includes deployment of nuclear power in weapons wouldn’t pass congressional approval or win public endorsement…. http://www.upi.com/Business_News/Security-Industry/2011/11/30/Brazils-nuclear-plans-stir-up-debate/UPI-27811322687019/#ixzz1fJnQZ2Ij

‘Sweden acted as vassal state to US’ in Assange case – journalist
New Generation IV nuclear power- PRODUCING EXPERTISE FOR THE NUCLEAR WEAPONS INDUSTRY – theme for May 2017
“Peaceful” nuclear power and nuclear weapons are intrinsically connected. The weapons industry itself recognises this.:
“There is no technical demarcation between the military and civilian reactor and there never was one. What has persisted over the decades is just the misconception that such a linkage does not exist.” – Los Alamos National Laboratory
The “new nukes” Lobby would have you believe that with their (so far non-existent) Generation IV nuclear reactors, there is now no connection with weapons.
Well, there IS – whether it be producing materials for bombs, especially “dirty bombs” and as an attraction for terrorists, or as a target for enemies in war-time.
The more subtle connection – PRODUCING EXPERTISE FOR THE NUCLEAR WEAPONS INDUSTRY.
While the “conventional” and the “new” nuclear industries both claim that they have no connection with weapons, the Generation IV spruikers actually claim to promote non proliferation of weapons.
In reality, much the same expertise is needed for both.
Generation IV nuclear reactors cannot get private investment (beyond a small group of billionaires). They depend on tax-payer funding. You would think that this situation would be pretty much fatal for their industry. However, with the conventional big nuclear reactors industry in a financial meltdown in America, and France, the nuclear industry as a whole desperately needs a boost.
The nuclear weapons industry needs to maintain a troop of experts, and to attract young men and women. The new gee-whiz “renaissance” for Generation IV forms just such an attraction. The support for new nukes includes generous funding for universities in USA and Britain. Whether that support comes from government or from industry hardly matters. The nuclear weapons industry benefits from an assured supply of nuclear physicists and chemists whether their training is supposed to be for new nuclear power, nuclear medicine, Small Modular Nuclear Reactors.
No doubt the global nuclear industry is very busily trying to influence academia. The most glaring example of this in the English-speaking world, is the University of Saskatchewan funded by Saskatchewan government and nuclear industry to develop SMRs. Other American examples – University of Missouri, and 29 other universities. In Britain, there’s University College London, Cambridge University’s funding from nuclear weapons industry , University of Bristol ‘s funding from secretive British organisation The Atomic Weapons Establishment. In Japan, it’s civil-military cooperation in Japanese universities. Even inAustralia they set up Adelaide’s University College London (UCL) -pro nuclear research funded by nuclear interest
