Fukushima crisis: Japan rises to highest level to Chernobyl


Nuclear Security Agency of Japan has decided to increase the severity of the Fukushima nuclear accident 5 A maximum of 7, which equates to the one in Chernobyl in 1986.
The agency said that the reactors damaged from the tsunami of 11 March at the Fukushima Daiichi Nuclear Power Station have been releasing massive amounts of radioactive substances into the air, posing a risk to human health and the environment of the area.

However, the level of radioactive emissions registered since the beginning of the nuclear accident in Fukushima is equivalent to 10% of those measured after the Chernobyl disaster, which occurred when the reactor was operating at full capacity, whereas Japan had operations arrested by the earthquake.

Fukushima Nuclear Accident


The spokesman for the Nuclear Security Agency, Hidehiko Nishiyama, explained that, unlike Chernobyl, the radiation level Fukushima, despite being high, allows operators to work on site to stabilize damaged four more units.

However, the company that owns the plant, TEPCO, said shortly after the amount of radiation released could exceed the issued following the Chernobyl accident and the Fukushima Nuclear Accident.If Fukushima still emitting radioactive material, the amount may exceed that of a nuclear incident occurring in 1986 in Ukraine, said Junichi Matsumoto, of TEPCO.
Nishiyama has insisted that the two accidents, the only ones that have been rated INES-7, are different, as in Chernobyl exploded reactor core, while hydrogen detonations Fukushima affecting the external building units.

The increased severity of the accident at the international level is based on provisional estimates of the Japanese nuclear agency, which has detected high concentrations of cesium and radioactive iodine in the area.According to Nishiyama, emissions of iodine 131 from the beginning of the crisis terabecquerel over 10,000, down from the hundreds of thousands of terabecquerel cast at Chernobyl (Ukraine).

Fukushima and the Ecology

Shortly before the news is confirmed, a new fire has been extinguished and alarm bells ringing at the station. This time has been the No. 4 reactor that has experienced the fire, according to Kyodo news agency reported. In the area there has been no change in radiation levels, according to the same source.
The fire was spotted by a worker at 6.38 am (21.38 GMT Monday) in a building near the exit to the sea water reactor. According to TEPCO, the company operating the plant, the operator detected smoke in the place where the test samples of water south of the plant and immediately alerted fire fighters work at the facility, which quelled the fire.

Climate Change Threatens to 58% of protected species in Europe


By 2080, 58% of terrestrial vertebrate species and flora in Europe could lose the climatic conditions to survive in protected areas in each country. So says a study by the Consejo Superior de Investigaciones Científicas (CSIC) published "Ecology Letters.

The authors, led by Miguel Araújo, analyzed the effectiveness of conservation policies in 75% of terrestrial vertebrates and 10% of the plants on the continent. In their analysis also shows that these changes affect more than half of the species included within the network of European conservation 'Nature 2000', up to 63% of them.

The Climate Change

The mountainous areas, valleys and enclosed water lines play a fundamental role in the adaptation of biodiversity to climate change. By providing temperature and humidity gradients accented, says the study, facilitate the adaptation of species through a short-distance movements are more feasible and less risky than inland migration.

Natura 2000 covers 27,661 areas, resulting in a total of 117 million hectares constitute 17% of the surface of the 27 countries comprising the European Union. The network's objective is to ensure the survival of biodiversity in the long term and the climate change. In addition, each country appoints its own protected areas. This makes Europe the region with the largest conservation network in the world.

Ecology and climate change

Researchers have used several climate models to study the potential distribution of 1,883 species, 585 terrestrial vertebrates and plants in Europe 1298.

Miguel Araujo explains, the National Museum of Natural Sciences in Madrid, "we noted that protected areas conserve species better against the effects of climate change, but the Natura 2000 network is more vulnerable and could lose more species."

Conservation areas designated by each country are more effective because they are usually located in mountainous areas, which act as 'climate refugees'. Natura 2000, the species are more vulnerable because they live in plains, where the effects are intensified by climate. in the ecology Research confirms that suffer the greatest impacts of southern Europe, while high mountain areas in Europe will be less affected.

Fukushima: The catastrophe of Japan and the future of nuclear energy

The six reactors at the nuclear plant in Fukushima-Daiichi were designed to be automatically stopped if there was an earthquake measuring over 6.2 on the Richter scale. When Japan was hit on March 11 by an earthquake of intensity 9, the strongest in its history, nuclear safety systems, as expected, stopped nuclear fission reactions in the three active reactors.
But after the nuclear shutdown, the radioactivity of the fuel is still generating about 6% of heat from the reactor at full capacity. And this heat production decreased only slowly over a period of months to years.

Fukushima and the nuclar energy

During normal operation, the core of a reactor with fuel rods is totally immersed in water and housed within a steel containment vessel. The heat produced by nuclear fission raises the temperature of boiling water to cause, and the high pressure steam produced drives a turbine to produce electricity, after passing through the turbine, the steam is condensed and cooled water returns to the core reactor, thereby achieving a constant temperature of 300 º C in the water under a pressure of about 75 atmospheres. All the reactor in the nuclear energy cooling system keeps running with power.

The earthquake crippled the grid, which was activated the emergency cooling system powered by diesel generators. Unfortunately, they were placed in a shallow part of the building complex of reactors, perhaps unwarranted confidence that the retaining walls would protect them against the sea, a tsunami and the ecology.

Future of the nuclear Energy

By the tsunami, an hour after the earthquake, the water had flooded the area where diesel generators and they stopped. Activated the emergency cooling system operated with batteries, but these were quickly exhausted.

Thereafter, he began to raise the temperature of fuel rods in the reactor core and glimpsed a disaster due to the inability to keep them fully immersed in water for losses due to boiling. Firefighters used several interconnected trucks to inject water under pressure in the reactor in the nuclear energy core affected. But the boiling water and steam became more rapidly than it could be replaced.

Green Energy: A sky greener


Fly and pollute less. The European airline sector is undergoing a time of change to achieve these goals. Europeans more and fly further, and want to do it in a more sustainable and to meet these needs has become one of the most important challenges in the sector, as has been demonstrated during the international conference 'Aerodays 2011' which was held this week in Madrid and the ecology.

The Minister for Science and Innovation, Cristina Garmendia, and European Commission Vice President Siim Kalas, gave the kick-off on Wednesday the largest aviation event of R & D in Europe. For three days in Madrid was the showcase that presented the latest research and proposals for reducing the environmental impact of civil aviation and reduce oil dependency looking for new biofuels.
Ecology and the air polution

Around 1,400 experts and representatives from over 45 countries participated in this conference organized by the European Commission and the Center for Industrial Technological Development (CDTI) of the Ministry of Science and Innovation and the ecology.
Reduce emissions, save energy and find alternatives to oil biofuels, and to reduce noise from aircraft and airports more efficient building concern of everyone: governments and citizens, companies that develop the technology needed to achieve and airlines, which they see as the price of oil soars and its reserves are depleted.

Green Energy in the Air

The report 'Flightpath Vision 2050', presented during the conference, stressed the need to move towards sustainable aviation with green energy, capable of reducing the environmental impact that will lead to increased air traffic expected by mid-century. Experts estimate that will rise on average by 5% each year over the next two decades.

Fukushima threatens fight against climate change

Climate Summit in Cancun (Mexico) 2010, Japan noted for his opposition to extending the Kyoto Protocol and its commitment to a UN agreement that both signatory countries as emerging economies limit their greenhouse gas emissions .
A few months later and after the disaster of Fukushima, the Japanese firm position on climate change loses steam. Japan might reconsider its promise to cut emissions by 2020, said an official of the Ministry of Environment in the press Japan.
Later, Yukio Edan, Chief of Staff of the Government came to the fore to qualify the bad news: Tokyo will have to analyze the impact of the crisis on many policy Fukushima and industries, and climate change will be one more. Japan plans to reduce its emissions of greenhouse gases by 25% in 2020 to reach 1990 levels. However, this goal now seems a little more diffuse. "Right now, we have not decided whether to review that goal and we are not at a stage where we can make a decision," Edan said.

Fukushima and the Ecology

Even more direct was Hideki Minamikawa, administrative vice minister of Ministry of Environment: "It is true that our goal of reducing [emissions] will be affected significantly," recognized as recorded by the newspaper 'Yomuri'. Minamikawa is these days at the meeting in Bangkok on climate change, a prelude to the upcoming UN summit in Durban (South Africa).

The truth is that the complex of Fukushima was a fifth of all nuclear power in Japan and the disaster forced Japan to rethink energy policy. While reviewing the security measures of various plants throughout the country, international representatives gather in Bangkok expressed concern about the future.

The chief negotiator of the European Commission, Artur Runge-Metzer, acknowledged that the crisis of confidence in the nuclear impact on international negotiations on climate. "Nuclear is one of the energy that emit few greenhouse gases, the origin of climate change," said European press conference. Runge-Metezer also stressed the need to rethink our model of development, alternative technologies and renewable energy.

Fukushima and the nuclear energy

For its part, the chief economist of the International Energy Agency (IEA), Fatih Birol, on Friday joined the voices of warning about the consequences of the catastrophe of Fukushima in the fight against climate change. Following the announced suspension of some nuclear power plants in Germany and the growing pressure in some countries against the extension of power plants or building new facilities, the nearest future resembles the past.

The gas and coal are back on the table. Looking to house, in late February, Miguel Sebastián defended the commitment of the Spanish Government for coal to ensure our security and energy independence. A month later, the data said that the main energy source in Spain in March had been the wind.
However, since international agencies warn: the abandonment of nuclear power using fossil fuels would increase by 0.5 gigatons of CO2 emissions by 2035, according to Fatih Birol. And Durban expected.

Ozone destruction: Record in the North Pole

The ozone layer in the North Pole suffers a unprecedented level of destruction caused by exceptional weather conditions, reported today the French organization National Center for Scientific Research (CNRS).
Late last month, the thinning of the ozone that protects Earth from ultraviolet rays was 40% and there was a "large area", a phenomenon never before observed, the CNRS said in a statement.

The reason for this decline is "a very trust stratospheric winter and persistent" leading to ozone destruction "important" and "exceptionally long until spring."

The Ecology and the Ozone

The European Space Agency (ESA) specifies that the record in the ozone layer is due to strong winds known as 'polar vortex'. This phenomenon isolated air mass over the North Pole and prevents it from mixing with air from midlatitudes. As a result, the state-of-freezing temperatures is very similar to that occurs every winter in Antarctica. Enviasat satellite, ESA has provided data to measure ozone levels.

The destruction of the ozone layer is linked to the presence in the atmosphere of various gases, emitted by aerosols.

At 80 degrees Celsius these gases become harmful to ozone, a phenomenon "recurring" in Antarctica, where temperatures are extremely low "every winter, but less common in the North Pole, where the temperature is higher and conditions more variable weather.

"I do not always meet the circumstances to produce a significant decrease of ozone in that region, said the CNRS, noting that" extreme weather conditions are responsible for the record achieved "this year.

Ecology and the deterioration of the ozone

French scientists, supported by the data sent by monitoring stations deployed on the ground, are now trying to determine the impact this phenomenon will have when the masses of ozone-poor air moving once temperatures rise with the advancement of spring in the ecology.
The CNRS warned that the deterioration of the ozone layer would have been higher in 1987 had not signed the Montreal Protocol, which limits the use of aerosols.

These products, which emit gases rich in chlorine and bromine remain in the atmosphere for years, so that the French scientists did not rule out destruction of the ozone layer similar to this year be repeated if there are again exceptionally cold winters and the ecology .
According to the latest assessment of the ozone layer, this gas will not recover its 1980 level until the years 2045-2060 at the South Pole and one or two decades earlier in the North.

Wind energy, the main source of energy in Spain



Wind power has become the first major source of energy to overcome during the month of March to other technologies, including combined cycle gas and nuclear, said Spain's Red Electrica (REE) and Business Association (AEE) in separate statements. Wind farms occurred in March 4738 gigawatt hours (GWh), which accounted for 21% of all electricity generated, and a 5% increase over the same period of 2010 and a record within a month.

Following this contribution of 21%, wind becomes the first source matrix generation, ahead of 19% nuclear, 17.3% of hydraulics, 17.2% of the combined cycle, the 15% of the CHP and others, coal 12.9% and 2.6% of solar. Wind power has also closed the first quarter as the main energy source, with 21%, which contributed to 57.9% of the electricity they occur without CO2 emissions.

Wind energy, good energy

With a contribution from wind, renewables energy covered in March 42.2% of demand, down from 48.5% in 2010 due to hydro production was exceptionally high last year. In the first quarter, renewables accounted for 40.5%, compared to 44% in the first quarter of 2010.
Saving 250 million.
ESA notes that wind power in March has produced enough electricity to cover the consumption of a country the size of Portugal and has been avoided in only one month a transfer of income to other countries of 250 million, due to oil imports. In total, the wind prevented the emission of 1.7 million tonnes of CO2 in March, the equivalent of planting 850,000 trees, and the market has shifted to more expensive technologies.
Est circumstances, the association says wind was the main reason that 2010 was the first year that Spain had an export balance of electricity from France. The average annual cost of the Spanish electricity market was the year of 38 euros per megawatt hour (MWh), compared to EUR 47.5 MWh of France.

Wind Energy and the green energies

"This milestone reached for shows such as wind energy, in addition to being indigenous, clean and increasingly competitive, it is a reality capable of supplying and thirteen million Spanish households," said ESA President, José Donoso.

The wind closed the year with an installed capacity of 20,676 megawatts (MW), in line with the objectives of the Renewable Energy Plan 2005-2010. ESA calls on the Government to establish as soon as possible the new regulatory framework to replace the Royal Decree 661/2007, which expires at the end of 2012, and offers the 'roadmap' to reach the EU in 2020.

Germany goes out against nuclear power


We are on the eve of two important regional elections, but government programs are discussed and crowded rallies are held.
e ability to mobilize German society turns spring Saturday in large anti-nuclear demonstrations across the country. Potsdamer Platz in Berlin, tens of thousands of people dance and sing the old songs of the 70 anti-nuclear struggle, carrying large banners with pictures of Fukushima and openly hostile slogans against E. On and RWE, two large energy companies that threaten to a multimillion-dollar lawsuit asking the State compensation for breach of the covenant which closed in the fall with Merkel, prolonging the active life of the reactors until 2040 and the atomic energy.

The German Government, in a radical shift in energy policy, caused by the disaster in Japan, has been disconnected seven of the 17 anti-nuclear reactors and today took to the streets to demand the permanent abandonment.

"Only a matter of time!" repeated again and again, protesters against the police lines protecting, if anything, the Bundesrat. The protest also passes by the headquarters of the CDU, the Christian Democratic Party, a supporter of nuclear energy until a couple of weeks and now heads the movement of "relinquishing control" of atomic energy.

Nuclear Energy



Only a few months ago, Greenpeace climbers hung down the front of the Konrad Adenauer House displaying giant posters against nuclear, but now walk past the main entrance with no hint of reproach, despite polls showing that nearly 80 % of Germans believe the conversion is finished Merkel to the anti-nuclear cause and consider it rather an electoral gimmick that will fade with time.
But there seems to be going back. At least not in this crowd is sure sign of victory. "Did not you hear the deafening noise? The collapse of the nuclear age sounds like your day sounded in the fall of the Roman Empire ... and we have to celebrate!" Says a man in his 50 years leading to his grandson perched on their shoulders, convinced that together we are living a historic day.

Many of the placards referred to Chernobyl. After Greenpeace has equated the two tragedies.

Atomic Energy

The large amount of radioactivity released Fukushima plant since the accident which started on March 11, radionuclides of iodine-131 and cesium-137, are evidence supporting that this incident be reclassified and placed in the same category the one at Chernobyl, which occurred in April 1986, reports Ingo Freschen, coordinator of the ecopacifista in Berlin and serving media in an impromptu press center, next to a hot dog stand on the porch of Sony Center.

"This has nothing to do with the election campaign. Do not be so myopic. This is a movement much bigger and more powerful regional elections, is the determination of several generations have been finally convinced that so far We lied. We were told we could not do without nuclear power if we wanted to maintain our lifestyle, our Western economies, with all our freedoms, would go to waste, and it was not true. I have in front of their noses. Germany offline seven reactors and not only we did not sink, but has barely noticed the quake and all that happens is that we are celebrating this great feast, instead of staying at home spending unnecessary energy, "insists Freschen.

As was the case this winter, in protests against nuclear waste transport Gorleben, the group that nurtures these manifestations is a cross section in terms of age, intention to vote and social stratum, which gives much greater potential to claims, they can no longer be ignored by any political force in Germany.

An hour of blackout for the planet's health



The  "Earth Hour 2011", an idea that is developed annually for five years to demonstrate the concern of humanity from climate change. How to join.
The blackout, which will take place today, March 26 by the end of an hour, will be developed with cascading effect on all countries, at their own time zone, between 20:30 and 21:30, and will involve, according to their organizers, more than one billion people.
Last year it began in the Chatham Islands, about 800 miles east of New Zealand, and covered step by step across six continents, from Mongolia to Antarctica, keeping pace with the rotation of the Earth.

The  Earth Hour

Globally, the action is coordinated by the World Conservation Organization (WWF, according to its acronym in English) and locally by the World Wildlife Fund.
The measure not only aims to save energy, though it entails-but above all, create a space for thinking about preserving the environment, getting people involved in these problems and promote personal actions, group and government, to curb their degradation.

"Earth Hour" was born in Sydney, Australia, in 2007 and then called two million people just in that country.
In 2008 were more than 50 million people in about 400 cities synchronized blackout, which left without lights in buildings like the Sydney Opera, the Coliseum in Rome, the City Hall in London, the Empire State Building in New York, the Tower of Sears in Chicago, the Eiffel Tower in Paris and the Golden Gate in San Francisco.
In 2009, more than 60 countries were involved in the blackout to combat global warming, with the message that they can act individually with small changes in everyday life, such as replacing ordinary light bulbs with fluorescent lights or low-power .

The Hour fot the Planet

2010, and had joined the blackout 1,500 cities in 128 countries on six continents, and were more than 1,300 monuments and landmarks of major cities in the world held in darkness for an hour. But this year, Earth Hour wants to beat his own record of participation and involve more than one billion people on six continents.

Environmentalists predict that, to continue the present status quo, the global warming could cause the extinction of 35% of terrestrial wildlife by 2050. Also, does carry deep floods and droughts, climate change increasingly threatening as the production performance and life of people.
For that reason and because it is necessary to engage world leaders in concrete policies to reduce emissions of greenhouse gases, it is expected that this time more than one billion people will join the symbolic gesture of turning off the light on Saturday, eight and a half to half past nine p.m., in the certainty that the planet is well worth it.

The study 'final' report on climate change


"The climate change debate has been usurped by the 'exaggerated' and the 'deniers'," says physicist Richard A. Berkeley Muller. "It is time for scientists to return to put things in place: less distortion, more science."
In the midst of an ideological war on global warming, Professor Muller-author of "Physics for Future presidentes', has decided to stand in the middle and try even harder: to develop the most comprehensive, independent and 'final' on climate .
The study has been dubbed "The Berkeley Earth Project 'and aspires to be" a new starting point to set the record straight and try to build a consensus. " Muller, in a telephone conversation with the world, anticipates that the results will be ready in next April or May.

The Climate Change

"The scientist's work is to investigate, analyze results and in any case provide the information to the public to draw their own conclusions," says Muller. "Much of the problem has arisen at the time that scientists have tried to be too activist and have lost their credibility as researchers."
'Exaggerated' vs. 'Denial' adn the climate change.
In the bunch of 'exaggerated', Muller talks about everything from Al Gore, but has many more reservations about criticizing NASA climatologist James Hansen ("your work as a scientist has been very valid.") At the other end of the scale puts the 'deniers', who should not be confused with the 'skeptical' ("an appropriate dose of skepticism is always desirable in a scientist) and the ecology.
According to Muller, the tendency to distort climate science to incite to action "has seriously compromised the work of the UN Intergovernmental Panel (IPCC by its acronym in English). "I will be very difficult to regain credibility," he warns, "as long as the front Rajendra Pachauri."

Berkeley physicist intends to go even beyond the work done so far by the UN IPCC, by the NASA Goddard Institute or the UK Met Office, the three major global benchmarks, trapped in one way or another the "politicization" of climate science, especially after the publication of the emails from the University of West Anglia.

"We're not going to manipulate the findings, we find what we find," says Muller, who claims to be ranked along with many other scientists at an intermediate point of debate. "We are an independent, nonpartisan group. We will collect the data, we analyze and present the results.'ll Let people draw their conclusions."

The ecology and the Climate change

Muller has been proposed not only conduct the largest study to date on the evolution of the temperature on Earth since the eighteenth century, but also make measurements "more stringent climate today, with data from 39,340 stations worldwide.

With the support of the University of Berkeley (the 'laboratory' Energy Secretary Steven Chu), the study is being funded by groups of very diverse: from the Innovation Foundation for Climate and Energy Research (created by Bill Gates ) to the Charles Koch Foundation (linked to the oil magnate).

Richard Muller argues in any case the "autonomy" of the Earth Project has received funding on the grounds that "both the left and right" and trying to lend a ember researchers who have not taken a political party. His team included Professor of Statistics David Brillinger, climatologist of Georgia Institute of Technology Judith Curry, and physical Saul Perlmutter, Art Rosenfeld and Robert Jacobsen, University of Berkeley and the ecology.
According to Muller, the evaluation "independent" global warming may be used as a reference in the U.S. and worldwide, "although we assume that a minority opinion will never change even though the evidence is or is not on your side" .

"Can we reach the same conclusions as other groups, but we will do a new and different," says Berkeley driver of Earth Project. "If all we get is permir consensus on global warming-a true consensus, rather than one based on policy positions," it will be a major achievement. "

Ithaca the ecology city


There is no better way to take the pulse of the "other" America to return again and again to Ithaca. There, in that small city ambush between lakes and waterfalls, we started our "green route" for almost year and a half. Here we are closing the circle now in these times of crisis, with one of its most illustrious neighbors checking the possible future path with the ecology city.

     "Choosing a Sustainable Future" is the title of the book by Liz Walker, co-founder of the EcoVillage of Ithaca and explorer of the Arabian initiatives that converge in this vibrant city and "green" than most. While much of the country was mired in recession, social and ecological activism of Ithaca came just at boiling point, as we saw in our last visit.

The ecology city

"This city has become the meeting point for people willing to have another relationship with the land," says Walker. "And in recent years has accentuated what I call the" cluster effect ", thanks to the cooperative spirit and healthy competition. This much we value and support the local economy, and this allowed us to better cope with difficult times. "

       The Ithaca Farmers Market was one of the pioneers among the 5,000 that exist today in American geography. The hugely popular Greenstar was also the cornerstone of healthy food cooperatives. There you can can pay for some with "hours" of Ithaca ("time is money"), the colorful local currency and the ecology. Or subscribe to car sharing system (Ithaca Carshare). Or have the right to universal health insurance (Ithaca Health Alliance). Or make lines of credit and interest to small depositors would be unthinkable in any other place in America (Alternatives Federal Credit Union).

Ithaca, with a progressive tradition that goes back almost to the time of the Cayuga Indians (Liz Walker thinks he sees in them the roots of pacifism, feminism and sustainability), perhaps approaching that any member of the Tea Party disparagingly call a "socialist eco-city."

Socialist eco-city

      "In this country we are experiencing a political and cultural civil war," admits Liz. "Every time there is a larger hole between people who want to live in a manner respectful to the environment and the extreme right wants to eliminate all the environmental protections and the ecology."

      But now that most of the population lives in cities, we have no choice but to seek new models, and proposed this city of just 50,000 inhabitants (half of them students at the prestigious Cornell University or Ithaca College) is certainly encouraging and stimulating.

The summer of 2010 was the warmest in 500 years

The summer of 2010 was the warmest of the past 500 years and their temperatures are not exceeded until after 2050, according to a study by the University of Lisbon in Portugal which is published in the online edition of the journal Science.

The heat wave that hit large parts of Eastern Europe last summer was even hotter and more extensive than the European heatwave of 2003. The warm weather last summer led to a significant number of victims and the ecology.

The Climate change

In Russia alone, there were more than 55,000 heat-related deaths, major forest fires, loss of 25% in the collection of crops and a total economic loss of around 1% of gross domestic product of Russia.
More frequent heat waves.

The researchers, led by David Barriopedro, put into perspective the heat wave when compared to other temperature anomalies in the historical record dating back to 1871 in terms of duration, spatial extent and temperature and the ecology. The authors determined that this episode was more severe than in 2003.

The most warmest Summer


The scientists also found that at least two summers in this decade were probably the warmest in the past 510 years in Europe. An analysis of the results of climate models indicate that the major heat waves are likely to become 5 to 10 times more likely in the next 40 years, although an episode with a magnitude to reach the warmth of 2010 is unlikely to occur until after 205.

The melting of glaciers will significantly raise the level of the oceans



The vast majority of frozen water on Earth is found in large ice shelves in Greenland and, above all, Antarctica. Therefore, when studying the effects of global warming on the rise of the oceans, these places are the center of attention in the glaciers and the ecology.

However, an international team of researchers led by the American Marcus Meier believes that this approach is wrong. "We have shown that glaciers and ice sheets, not the two great ice shelves, are the main culprits of rising sea levels for at least the next generations," said Meier, who signed with colleagues an article published this week in Science and the glaciers.

According to estimates made by the team of scientists, the study shows that the contribution of glaciers and ice sheets is about 60% of the water entering the oceans as a result of global warming. The melting in Greenland contributes about 28% of the total and the Antarctic with only 12%. Paradoxically, the place on earth where there is more ice is the least contributing to rising sea levels, and vice versa.

The future of the Glaciers

Also, Meier and his colleagues believe that in future this trend will be reinforced. As glaciers and ice caps will melt faster and faster, Antarctica will at an increasing rate, but much slower. In fact, estimates suggest that the eastern half lose no ice. Consequently, the share of glaciers and ice caps in the rising seas will be even greater.

2100, and depending on the scenario chosen (with or without acceleration in the melt) rise in sea levels as a result of climate change will be 10 to 25 centimeters. To this must be added that from the other reserves of ice. According to the International Panel on Climate Change, for the year it is expected that sea level has risen between 20 and 50 centimeters.

The ecology and the Glaciers

There are two mechanisms by which global warming destroys the glaciers and ice sheets. On the one hand, the glaciers are moving faster, and throw more ice to the sea. On the other hand, the icebergs from these glaciers and ice caps are melting faster because the ocean water is warmer. In theory, if those ice to melt completely global sea levels would rise one meter.

Solar Energy, a sustainable alternative for the future



The sun is the source of energy for billions of people, if governments are committed to creating photovoltaic markets, the report "Solar Generation" by Greenpeace. (18/10/2001).

The sun is the source of energy for billions of people, if governments are committed to creating photovoltaic markets, the report "Solar Generation" by Greenpeace. (18/10/2001).

Solar power could provide electricity to more than one billion people, creating approximately 2 million jobs by 2020 and reach 26% of global energy needs by 2040, according to a report released today in Berlin by Greenpeace and the European Photovoltaic Industry Association (EPIA).

The solar energy in the future

The report "Solar Generation" shows that solar PV has the potential to make a large contribution to both the future of world energy supply security and to help avoid the danger of climate change. "It's a realistic and achievable goal, based on the state of the industry and market opportunities that exist today, but requires a clear political support from governments around the world," said Sven Teske, energy expert Greenpeace. "We need a massive boost to renewable energy sources if we are to eliminate fossil fuels that threaten our climate."

"We have a clear signal from governments that there is a political commitment to increase the role of solar electricity in the energy mix. In particular, the Commission should ensure that national innovation systems of incentives for solar electricity not be invalidated by the competition policy, "said Jose Luis Garcia Ortega, responsible for Spain Greenpeace Solar Project and the ecology.

"Greenpeace calls on governments to provide renewable energy to two billion poorest people the world over the next ten years. Even using conservative estimates, the report shows that solar energy can cover much of this demand, and create millions of jobs worldwide. "
EPIA, which represents 54 major European solar companies, is responding to this challenge to strengthen its role as global advocate for solar energy.

Ecology Solar energy

The report shows that by 2020 the global solar production would be 276 terawatt-hours, which could equal 30% of the energy needs of Africa, or 10% of the demand for European OECD countries, or 1% of global demand. This would replace the energy produced by 75 new coal power plants and prevent the emission of 664 million tonnes of carbon dioxide. Solar infrastructure investment would be worth of 75 billion dollars a year, and lower the cost of solar modules, $ 1 per peak watt.

By 2040, global solar production could be over 9,000 terawatt-hours, or 26% of expected global demand, which would have increased from 27,000 to 35,000 terawatt-hours. This production exceeds the combined demand of the European OECD countries and North America in 1998 and the solar energy.

Renewable technologies, which use energy not only the sun but also wind and water, generate clean energy and will end or cause the accumulation of greenhouse gases that cause climate change.

The glaciers are melting faster than expected



The ice sheets of Greenland and Antarctica in the south are losing mass at a rate faster than the predictions had been made so far, this will impact significantly on the rise in global sea level, according to a study released this NASA Wednesday.
The study report suggests that ice sheets are crumbling faster than the glaciers in the mountains and this will be the main factor that contributes to a global rise in sea level, much earlier than expected and the ecology.

The ecology and the glaciers

An example is the following case, in 2006 the Poles lost a combined mass of 475 gigatons per year on average, enough to raise global sea levels by an average of 1.3 millimeters per year compared to they lost 402 gigatons average of the mountain glaciers.

NASA has studied some information from satellites between 1992 and 2009 and subsequently obtained every year during the course of the study, the layers of polar ice caps have lost a combined average of 36.3 gigatons more than the previous year .
It is estimated that "The ice will be the main cause of rising sea level in the future is not surprising, since they have a much larger mass of ice that mountain glaciers," said study author Eric Rignot, University of California.

Glaciers are melting

"The bad news is that the greatest contribution of the ice is already happening," said the scientist who conducted research in collaboration with the Jet Propulsion Laboratory (JPL) of NASA.
The reports both show that "if current trends continue, it is likely that the increase in sea level is significantly higher than the levels projected by the Intergovernmental Panel on Climate Change in 2007 and the ecology."

The future of glaciers


The satellites have shown a more accurate picture of rapid weight loss that are suffering the ice off the coast of Greenland and Antarctica. This finding, published in the journal Nature, will enable more accurate predictions about future sea level rise that can cause this phenomenon linked to climate change and the ecology.

The deepest ice loss is due to accelerated melting of glaciers at the time that they meet the sea, according to a group of researchers from the British Antarctic Survey and the University of Bristol (Southern England) . In reaching this conclusion, the researchers analyzed millions of measurements of the huge ice sheets of both Antarctica and Greenland provided by NASA.

The glaciers and the ecology


The experts saw this "dynamic thinning 'glaciers experiencing now reaches all latitudes in Greenland, has intensified along the coast of Antarctica, is penetrating into the interior of ice sheets and is spreading in the form of thin layers ice due to melting of the ocean and the ecology.
The scientist Hamish Pritchard, the British Antarctic Survey (BAS) said that the "surprise" that these discoveries have led the researchers saw a pattern as strong thinning of glaciers in coastal areas as large. "

The Future of the Glaciers

"We think the most likely cause it has a faster flow on the glacier is due to the warm currents of the ocean when they reach the shores and melt the glacier," he says.
The expert admits that the phenomenon of melting is not yet well understood so it "remains the most unpredictable of the rise in sea level in the future and the ecology."

CiU proposed that the product labels indicate CO2 emissions


CiU parliamentary group will defend next week in the Environment Committee of the Congress of Deputies, a non-legislative proposal which proposes that products manufactured in a label detailing the emission of carbon dioxide (CO2) associated with its development with the aim of measuring the impact of each product in global warming and the ecology.

Thus, the CiU spokesman at the Commission for the Study of Climate Change, Carles Campuzano, believes that if given such information, be sensitized to the citizens and will promote the responsible consumption, so if consumers have this information you can choose products based on their own criteria for environmental responsibility.

Product labels indicate CO2 emissions

"It's about raising awareness among citizens, and promote more responsible consumption by providing the consumer with information as the trace left by the product acquired in the emission of greenhouse gases," he said.

Campbell notes that in countries like Britain, France, Switzerland and Finland and is included in some products this type of information. In that sense, has become such a British supermarket chain Tesco, which includes the label of the carbon footprint of products such as chips or orange juice, for example, the associated CO2 emission, or the French supermarket Casino also include such information in some products, as well as Migros in Switzerland or oatmeal in Finland. Also referred to the phone company Orange, which has begun to explain the traces of mobile telephony and the ecology.

CO2 Emissions and the Ecology

"We must extend this practice in Spain. With this goal comes the CiU initiative," said Campuzano.

For this purpose the non-legislative proposal CiU is urging Congress to urge the government to move forward within the European Union to establish uniform criteria for measuring the environmental impact of products, in terms of CO2 emissions and the ecology, and cooperate with the regions to promote that product labeling include information on its impact in terms of emissions.

Environmental groups demanding an end to fossil energy investments


A group of activists with white masks and charcoal-stained today protested to the Ministry of Finance to demand an end to World Bank investments made in renewable energies with the support of the Spanish Government and the end to fossil energy.

Organizations, Ecologists in Action, InspirAction and Friends of the Earth have expressed their displeasure against the Minister of Economy and Finance, Elena Salgado, "for contributing to the financing of fossil fuels in poor countries by 116% over the previous year ".

Under the slogan "World Bank climate criminal, accomplice Spanish government" and a basket full of coal and deposited outside the Ministry, environmentalists have moved to the head of the Environment his concern for the future implementation of the new energy strategy World Bank from 2011 and the ecology.

Financing of fossil energy and the ecology

In a statement read during the ceremony, the group's spokesperson InspirAction, Isabel Ortigosa, explained that the World Bank's energy policy "is to finance private sector projects to large scale fossil fuels, an approach that has clearly failed to to provide energy for impoverished communities. ".
The head of Ecologists in Action Tom Kucharz criticized in recent years, "World Bank financing for coal power plants has increased by 40", to a record 3,300 million euros in 2010.

The ecology and the end to fossil energy

Also, the spokesman for Friends of the Earth, Alejandro González, has warned about the "inconvenience" to stand by while the World Bank borrows the South, making it totally dependent on fossil fuels in coming decades and the fossil energy.

Protests like these will be carried out throughout the day in various parts of the world as Zagreb, Paris, Berlin, Rome, Johannesburg, Washington or London.

The 5 worst environmental disasters in the Worls

Mexico and other countries have confronted environmental disaster caused by the oil spill, the explosion of nuclear plants and disposal of chemical materials.

The 5 worst environmental disasters in the Worls

Persian Gulf, 1991: The war between Iraq and the United States caused a major ecological disaster of the twentieth century due to burning oil wells causing black rain that destroyed vegetation and polluted water by the oil spill.

Ukraine, 1986
: The explosion in a reactor of a nuclear plant resulted in a radioactive cloud over the Soviet Union and eastern Europe. Radiation finished with four square kilometers of vegetation and life of the Pripyat river.

India, 1984: A leak of 42 tons of methyl isocyanate that became toxic gases caused one of the worst disasters in memory. About 20 thousand people and thousands of head of livestock and pets died from inhaling the pollutants.

Mexico, 1979: The oil well Ixtoc I, belonging to Petroleos Mexicanos (PEMEX), is out of control and exploded causing a spill of 560 million gallons of oil into the Bay of Campeche, Ciudad del Carmen in the Gulf of Mexico.

Italy, 1976: An explosion at a manufacturer of perfumes and cosmetics, instantly killing 193 people and air pollution in 11 communities around the cloud of dioxin that is presented and the ecological disaster.

Japan stopped whaling in Antarctica by environmentalists

Japan has temporarily suspended its annual whale hunt in Antarctic waters because of the harassment of environmental organizations who rely on this controversial practice is now closer to an end.
A spokesman for Japan's Fisheries Agency announced Wednesday that the Nisshin Maru whaling ship crippled their catches on 10 for safety, to the aggressive practices of the conservation group Sea Shepherd, and evaluate what decision to make now and Japan stopped whaling..
The environmental organization Greenpeace was assumed that the return will be decided ahead of Japan's whaling, which processes the catches of three other boats with a total crew of 180 men, fishing with spears to the huge cetaceans.

Japan stopped whaling

The Japanese whaling season, which was to last until March, was suspended when the Nisshin Maru was in an area near Chilean territorial waters, according to the local agency Kyodo and Japan stopped whaling.
Whaling has been reported to Tokyo constant criticism throughout the world and even a complaint from Australia to the International Criminal Court in The Hague to hide, under assumptions scientific, purely commercial motivations and Japan stopped whaling..
In recent years, catches of the Nisshin Maru have been complicated by the sabotage of American Sea Shepherd in the cold Antarctic waters, with practices such as collision, release of corrosive acids or chains of the whaling activists, which have caused irritation in Japan .
Hunting whale

Japan, Iceland and Norway are the only countries that continue whaling, a practice that Tokyo is defended as an ancient cultural tradition, born on the coast of Taiji, Wakayama, who also holds a controversial hunting of dolphins and Japan stopped whaling..
The spokesman Minister of Japan, Yukio Edan, today deplored the stonewalling against the issuing "scientific" and said Japan will ask other nations to take action against him.

Global warming increases the risk of flooding


Scientists have long warned that the global temperature increase leads to changes in precipitation patterns. The basis of the argument is simple: more power means more heat in the atmosphere and it is therefore more water vapor and more activity in the system.
Experts say it is difficult to predict exactly how rainfall will change in every corner of the world, but they know that, because of the greater amount of energy in the atmosphere will become more common extreme events such as storms, hurricanes and strong temporary and the Climate change and the global warming.

Indeed, two articles recently published in the journal Nature corroborate these predictions. The authors argue that human emissions of greenhouse gases have substantially increased the likelihood of heavy rainfall and flood risk.

Climate change and the global warming

Francis Zwiers and colleagues at the Division of Climate Research Division of Toronto (Canada), have managed actual rainfall data recorded over half a century in the Northern Hemisphere to conclude that torrential downpours have more than doubled.


The researchers used the records of rainfall made by 6,000 different meteorological stations between 1951 and 1999 across the northern hemisphere. The ground covered includes North America and much of Eurasia to India. Data came from maximum rainfall in a single day each year and also recorded the maximum rainfall for a period of five days each year that are, according to them, that best reflect what is a torrential downpour Climate change and the global warming.

Global Warming

After implementing new computer systems for calculating all these databases, the researchers found that violent rainfall events have increased by two-thirds of the northern hemisphere in recent decades. In particular, records of daily maximum has increased by 65% of the stations and the maximum of five days in 61% of them.

Brazil introduced its new green jersey


The renewed coat with a green band unpublished breast height, was manufactured by recycling plastic drink bottles. Will be used for the first time on 9 February to France.According to marketing director of Nike, Thiago Pinto, the band-green in the yellow jersey holder, yellow and blue shirt in the alternative, was conceived as a "shield" of the players and the Ecology jersay.
"The band alludes to our ancestors, who painted a band on the body before every battle as a form of protection," said the executive of the sportswear company that is among the sponsors of the Brazilian team.
The other novelty is not visible to the public: on the inside, the coat has the shape of a canary, referring to the Brazilian teams that won titles in Sweden's World Cup Chile 1958 and 1962 and were known as "Canarinhas and the Ecology jersay."
The Ecology jersay

The authorized representative of Nike said the clothing brand of "Scratch" was produced by recycling plastic drink bottles, resulting in a lighter fabric than the one used before.
The presentation of the new Brazil shirt was made at the informal on the premises of the Museum of Contemporary Art in the city of Niteroi, near Rio de Janeiro, and without the presence of the coach, Mano Menezes, who must have presided the ceremony and the Ecology jersay.

However, according to the DT's Pinto "Scratch" no weather problems could return from Peru, where matches are watching South American U-20.

7,000 million humans in 2011

This New Year, on the surface of our tiny planet live 6.934 million human beings. Is more than double that just 50 years. Throughout 2011, the figure will exceed 7,000 million and the United Nations forecasts suggest that by the middle of this century will reach 9,000. Are some numbers that put the Earth to the brink of collapse, but more and more people understand that this is not an overpopulation problem, but an increasingly unbearable waste of natural resources are limited.
Among those now raised the old theories of Thomas Malthus is the World Population Foundation (DSW, its acronym in German). Malthus, in his treatise of 1798, and ventured that the population is growing faster than resources, and therefore predicted to produce wars, epidemics and famine among the poor to reach equilibrium and ecology.

Ecology and population

In a report presented in Hannover, DSW has reminded this week that 2.6 babies are born every second, emphasizing that 82% of the population lives in developing countries is in Africa where it grows at a faster pace.
In fact, it is expected that the African population will reach 2,000 million by 2050, double that of 2010. "Most African countries do not produce enough for its inhabitants. Poverty in Sub-Saharan Africa would reduce a fifth if there could prevent unwanted pregnancies," said in a statement ecology.
Its director, Renate Bähr going farther. "Today 75 million women in emerging countries have unwanted pregnancies because they lack information about contraception. If we want to fight poverty, we must prevent these pregnancies," he argued and the population and ecology.
However, other data points demographics: the pace of global population growth has fallen more than 40% since the 70's. Moreover, Europe is not reached replacement level (2.1 children per woman) and in Spain only 1.4, which is achieved thanks to the immigrants.

7,000 million humans in 2011

From another perspective, according to the Population Association of America, all the inhabitants of Earth would occupy the equivalent of the state of Texas, with 500 square meters for each family. So we really are so many? "No. And that rate of increase is declining rapidly. It is believed that will touch the ceiling in the 9,000 million, but this stabilization did not come from family planning imposed, but the reduction of poverty. When in Africa live better, have fewer sons, "says demographer CSIC Julio Pérez Díaz.

From the environmental field, Juan Carlos del Olmo, secretary general of WWF Spain, recalled that in its present rate of consumption, and are just two and a half planets: "The real bomb in this planet is the combination of a very high population with unbridled consumption. If all humans wasting resources, as here, break out "
