The North Pole ice free soon
According to the magazine heating is so fast that we risk a radical change already this summer
Ice at the North Pole
MONTREAL - The thin layer of seasonal ice that surrounds the geographic North Pole may melt in the coming months, so that for the first time this summer the North Pole could be free of ice .
is the hypothesis to the magazine National Geographic by some experts who are studying the effects of climate change on board the Canadian icebreaker Amundsen. "This year the North Pole for the first time could be ice-free," the magazine said David Barber, University of Manitoba. The forecast does not contradict the recent models that include the melting of Arctic ice between 2013 and 2030.
However, the dissolution of the thin layer of seasonal ice is considered by researchers as the alarm bells about the extent and rapidity of the changes caused by changes in climate. The hypothesis is based on direct observations and satellite images that show how the area around the Pole True north is composed of a thin layer of seasonal ice that forms each year that is winter.
An ice of this kind, said the scholar, tends to melt more easily during the summer compared to the thicker layer of ice and dense that accumulates over years. That is to say that "the ice near the North Pole is more prone to melt and, consequently, there is a high probability of seeing a North Pole ice-free, 'he said in an e-mail sent to magazine climatologist Sheldon Drobot, University of Colorado. But there are also high probability h, and the thin layer of ice, pushed in the direction of Canada the Earth's rotation, could also overcome the free summer.

Sea, nature and art to a step from home. Without spending too much. The development of tourism
Slovenia is experiencing new fortunes. Three reasons: outstanding natural beauty, especially affordable prices, many recreational opportunities. Adopting the solutions of accommodation such as renting an apartment (or, better still of rooms at a local family), the vacation will definitely original and affordable.
PLACES TO VISIT IN SLOVENIA
Postojna, Kobarid, Koziak Falls, Triglav National Park, waterfall Boka, Lake Bled, Vintgar Gorge, Lake Bohinj, Radovljca (museum of bees), Ljubljana, the Moravske Spa baths, including Ptui, the Certosa di Pleterje and spa Catez.
Slovenia is one of the regions of northern Italy, Friuli-like or the Valle d'Aosta. Small towns, villages and towns with many individual houses with a little 'of land around. A lot of agriculture, most family-run industry. A parking Postojna
say No Camping, camping is a further 8 km, all camping in the mountains, still nice and there's a pool, there is also the chance to put the food in the freezer type of ski rack and note that there are few vacancies.
Ljubljana Resort is much more than a campsite, is a green oasis of more than 7 hectares, a real park, located in a suburb north of Ljubljana, the Slovenian capital. This is the largest tourist complex in central Slovenia, with among other things, a hotel and a 4-star campsite. A paradise for a special treat! In fact, despite several opportunities for recreation, camping is extremely quiet and offers a holiday with full respect for the environment.
Ljubljana Resort offers countless opportunities to relax and highest service levels. At the edge of the camp there is a pond with a dock for boats. The space is huge and is an ideal base from which to explore the lakes and the Alps of Slovenia, tourist destination of the moment.
Camping Adria Ankaran is located on a small strip of land on the Slovenian Adriatic Sea, between the beautiful peninsula of Istria (Croatia) and Trieste. A wonderful area for a camping holiday with sun, sea and beach, but also an area rich in beauty to be discovered: the lakes and mountains of Slovenia, the unspoilt countryside and coast with the ancient port city of Koper (Koper), where the ferries to Ancona and Brindisi. Koper is a few miles from the campsite. Camping Adria is large enough, with a very pleasant and welcoming, thanks to the many trees and paths.
Camp Bled is located in a secluded, beautiful and tranquil setting on the shores of Lake Bled in the Julian Alps and Karavanke, raises two miles from the center of Bled.

Adrift a giant iceberg
It is detached from the ice of the Antarctic Peninsula Southwest . It is twice the size of the island
WASHINGTON - It 's a piece of ice of enormous size: an iceberg 41 km long and 2.5 km wide broke off the Wilkins Ice Shelf in the ice, a' area that scientists had predicted would collapse of not less than fifteen years. The cause of the incredible collapse, experts say, is climate change. Broke the news of the Centre national data on snow and ice (NSIDC) University of Colorado who has also released photos taken from a satellite.
SEVEN GREAT VES MANHATTAN - The iceberg is twice the size of the island and started to break away from the pack on 28 February. "This is a sign of worsening global warming," said scientist David Vaughan (British Antarctic Service). The giant fragment that broke off is about 4% of the total of Wilkins Ice Shelf, which measures an area of \u200b\u200bnearly 13,000 square kilometers (as the entire Trentino-Alto Adige). Only a thin layer of ice remained intact to prevent further cracking. Wilkins is about 1600 km away from the tip of South America on the southwest Antarctic Peninsula.
RECORD INCREASE IN TEMPERATURE - Over the past 50 years there has been an increase in this temperature record with more than half a degree Celsius every ten years. "The Wilkins Ice Shelf was there for at least a couple of hundred years, but hot air and the effect of the predicament caused the gap," said Ted Scambos of NSIDC. Since the summer Southern Hemisphere is at the end the researchers did not expect other developments: "This season the show is over," Scambos said. In recent years, broke off two big parts not far from the platform Larsen. In 1995 it had fallen to Larsen A, a block of ice 75 kilometers long and 37 km wide, in March 2002, a NASA satellite observed the collapse of the Larsen B platform in the east of the Antarctic Peninsula, a mass of 720 billion tons of ice disintegrated in less than a month.

WWF: the Alps and the Apennines with no ice and the animals threatened with extinction
LONDON - If you do not bastase the huge island of ice that broke off dall'Antardide to highlight the climate crisis on the planet, on a smaller geographical scale there are the animals that live on the Italian mountains to confirm this. Are the species that live in the Alps and in the central areas in so-called "limit", fleeing to higher altitudes in the hunt for cold, snow and ice. Of ptarmigan in Italy are 5,000 couples, a species considered on the brink of extinction with a population that is in continuous decline, the ibex in Gran Paradiso is decreased by about
The Calderone glacier in 2006 (Piero Angelini)
30% since 1990, the glaciers are in constant regression, the snow falling. The Alps and the Apennines Central appear on seating with climate change, definitely in a state of distress and profound transformation. It 'a study of the WWF to take stock of the portion of the peninsula that most influenced global warming, where the fragile balances are ready to jump in the presence of mercury continues to rise.
ITALIAN GLACIERS WERE REDUCED BY 40% IN 150 YEARS - The most visible effect of climate change is underway in the Alps, as is known, the regression of glaciers, glaciology, the Committee estimated that the mid-nineteenth century there has lost an area equivalent to 40%. In central Italy the first victim is the famous glacier Calderone, at 2800 meters above sea level on the Gran Sasso of Italy (d. 2912), which is slowly dissolving - considering glaciological dead - and with it its lead, to be the southernmost glacier of Europe, just because of the progressive rise in temperature of the Earth. In Lombardy, the last two years have been extinct 30 glaciers, including those smaller, more exposed to the south and lower altitudes, but also the largest and best exposed glaciers are no exception to the general trend as from 2003 are all in sharp decline of surfaces and thickness. The average loss in thickness of the Lombardy glaciers in the last 20 years was 2 meters per year, an eloquent example is the Glacier Alpe South (Valtellina, SO), who lost in the last 10 years about 16 feet thick.

animals involved - Changes of this magnitude in the wild, of course, also change the lives of plants and animals. If the alpine flora to a recent study, which lasted three years, led by the University of Pavia and coordinated by WWF, found the "escape" upwards for animals under the new parameter is detected by the WWF, if possible, even more dramatic. The species that live in the cold, while trying to adapt to new conditions, are in serious trouble. The most emblematic cases concern the ptarmigan el'ermellino, characterized by a white dress during the winter, valuable as a defense against predators and totally useless, even dangerous in the absence of snow. The partridge is now considered on the brink of extinction and in Italy there are only 5 thousand pairs. The ibex, a sort of symbol of the Alps, seems to suffer so important to the climate changes.
studies carried out in the Gran Paradiso National Park (where there are 50 years of data on population dynamics of the ibex) and in collaboration with the National Research Centre in Turin (CNR), shows that since 1992, the population is decreased dramatically, from almost 4000 individuals to less than 2500. The data also highlighted that the mortality rate of the population does not correlate with the death of older individuals, but with a decline in average annual survival of small, varied from 70% to 25% in a few years.

RACHEL CARRIE
Name: Rachel Carrie
Type: Tribute (for the living)
At the age of 23, Rachel Corrie was full of life. At the age of 23, she was a senior in college ignited by a passion for justice. At the age of 23, she traveled to the Gaza strip as an activist for peace. And, it was at the age of 23 that Rachel Corrie knelt to the ground wearing an orange fluorescent jacket as a 9-ton Caterpillar bulldozer came toward her, knocked her down, crushed her with its blade, ran her over, backed up, and ran her over again. At the age of 23, Rachel Corrie was loved by family and friends who would never see her radiant life again.
Rachel was killed trying to prevent the demolition of a civilian home by the Israeli army. Thousands of homes had been demolished, and Rachel along with her companions from the International Solidarity Movement were seeking to prevent further destruction. Through non-violence, this group of international activists was following the lead of Palestinians struggling to end the occupation of their lands.
Activists such as Rachel lived in Palestinian homes with Palestinian families hoping to help fend off attacks and destruction. They used their bodies to send a clear message of solidarity and resistance spelled in the alphabet of arms and legs, torsos and necks, hands and feet. It is this unmistakably human language that Rachel chose to speak in the face of machines programmed for death and devastation.
Of course, Rachel was not the first to die from the angel of death demolition policies carried out by Israel in occupied territories. Far from it, Rachel’s life was only one of many cut short by the sword of this oversized angel which feeds at the trough of US aid. Still, Rachel’s death garnered particular attention because US citizens take note when other US citizens die in the jaws of a winged monster who previously flew in other worlds, not ours. The previous victims were darker and of a foreign people. Our moral radar did not extend to their land and hue.
So, Rachel was not singular in her death, but this does not diminish her bravery. Nor should it diminish what her life can mean to us now. On March 16th, it will have been two years from Rachel’s death, and it is on this day that the memory of Rachel’s life can infuse our own lives with humanness. It is on this day that we can realize our world is also the world of Palestinians. It is on this day that we can realize that our world is also the world of Iraqis and Afghanis. It is on this day that we can look past the small horizons of our small worlds and see the stark, chilling reality of a sky filled with angels of death descending again and again, devouring our world, our humanity.
When we see this death-filled sky, we may choose to look away. We may choose to rationalize a way of focusing our vision elsewhere closer to home. We may say to ourselves, “I can do nothing” or “This problem is too big for me.” But, this is why Rachel’s life is yet again so important. Rachel’s life continues to this day to serve as proof that you and I can do something.
Yes, Rachel died in doing something, and we need not seek martyrdom. But, what is important is the manner of Rachel’s life before her death. Rachel died doing something that made her fully alive. As long as you or I believe that we can’t pursue peace and justice, we are only partially alive. We are only partial citizens of the planet. We are only sometimes concerned about some people. We are only sometimes loving and compassionate to some humans. In truth, to be only partially alive is to be one’s own angel of death.
Ultimately, I believe Rachel’s death should not be cause for despair. It should be cause for hope, a hope that each of us can choose to be more fully human despite grim forecasts of probabilities and risks. If we instead remain captive to our doubts and fears, we will only imprison our greatest potential. We will kill our own heroism by handing the keys of fate over to the angels of death.
On March 16th, let us not only remember the life of Rachel Corrie but let us also remember the possibilities of our own life. On March 16th, let us remember that Rachel Corrie at the age of 23 was full of life, a life that can continue to live through us.
(This speech was delivered at a toastmasters club in Berkeley, California. For those living in Berkeley, there will be a celebration of Rachel’s life on March 16th. See www.norcalism.org for details. Brooks Berndt can be reached at brooksberndt2466@yahoo.com .)

Monocrystalline cells: are produced by cutting a single crystal bar. The main advantage is a high efficiency (up to 16%). This type of cells is very expensive because of the complicated production process. Monocrystalline cells are usually characterized by a homogeneous blue color.
pole cells (multi-) crystalline: they are cast into blocks and then cut into disks. The yield is lower (10 ° 12%), but also the price. This type of cells can be recognized from a design easily distinguishable (because of the different crystal contents). Cells
amorphous: is produced by cathodic deposition of silicon atoms on a glass plate. This type of cell has a lower yield (ca. 4 ¸ 8%), but also adapts to the case of diffuse radiation (clouds, etc.).. The cells so produced are recognizable by a distinctive dark color, also can be made in any geometric shape (circular shapes are possible, octagonal, irregular, and even convex).

How Does Thrush Look Like
"DIY Wind Generator
Hydroelectric plants generate electricity using the kinetic energy of a quantity of water drawn from the movement of a river (flowing water systems) or stored in a reservoir and released in accordance with the needs of production (plants in the basin).
In a hydroelectric power potential of the mass of water fed through a pressure pipe is converted into mechanical energy from the impeller-turbine group, whose motion in turn is converted into electricity by the alternator group / generator. The energy produced can be immediately used, for example, food industrial, or be placed on the grid, while the water through turbines, without any pollution, is fully returned to its bed further downstream by a natural drainage channel, with no impact on the environment.
The power plant is proportional to the amount of incoming water (flow) and the difference between a levy and the altitude at which water is turbinata (jump). The law in force in Italy leads the standings on the basis of hydraulic installed capacity, whereas small branches with the central power of less than 3,000 kWh and large-scale diversions than those of average power.

The idea of \u200b\u200bharnessing wind power to generate a rotary motion is centuries old, first cousin of the water wheel technology.
The main advantage of the exploitation of wind energy is a never-ending source of energy and totally free and a limited environmental impact given that the design factor is not required dams and channels as it does for the hydro plants.
The limit of a wind turbine is the reduced air density that generates limited power in the size of the wind turbine. To get an idea of \u200b\u200bthe relationships in play enough to consider that the air density of approximately 1,225 kg / m, is related to 1 / 816 compared to average water.
It so happens that an output of 1 MW represents more or less the lower limit for the applicability of a hydraulic turbine is a power but very respectable for a wind turbine.
The operating principle of a wind generator is more or less well known. A system of blades, placed in rotation by the energy of wind, which generates a rotary motion, through appropriate mechanisms, is transmitted to an electric generator.
If you look at a wind turbine, especially in photography, where you lose the effect of imposing tower of support and the huge blades spinning, you have the feeling of being faced with a quite boring machine, a variant of the windmills that survive in the world with tourist purposes only. In reality the technology used to design and build a wind generator is taken directly from engineering and sophisticated avionics. The writer has worked for more than three decades in the field of mechanical design in various fields, including engineering of hydraulic turbines, and can say that the design of a wind turbine business is of great satisfaction and commitment.

hydroelectric technologies have a good development in terrestrial applications, ie using the water cycle, evaporating from the sea, is transported to the mountains where the clouds descend to the valley allowing the interception of its energy kinetics, these applications are as follows, still good scope for development, very interesting but still under development are technologies that hide huge potential tidal energy.
Hydroelectric plants are currently operating the mechanical potential energy contained in a flow of water that is available at a certain height from the level where the turbines. Therefore, the power of a hydraulic system depends on two terms: the jump (difference exists between the share to which the available water resource flared and the level at which it is returned after passing through the turbine) and scope (the mass Water flowing through the machine, expressed per unit of time).
plants are natural reservoir (lake) or artificial, as in the case of many reservoirs, ponds are sometimes where you increase the capacity with dams, in many cases the barriers consist of many tens of meters high dams.
Plant Flow regoato (a basin)
are today's most powerful hydroelectric plants and the most exploited, have a significant impact on the environment, can be used as "accumulators" of energy use during peak hours pumping water from downstream to upstream
at night are provided with a storage capacity of the outlet stream tending to modify the ports used by the central regime, these plants are generally higher than 10 MW of power and come to such enormous power plant of Itaipu in Brazil, has a basin with an area of \u200b\u200b1460 square kilometers (4 times the lake Garda)
reservoir or accumulator plants are plants with all
the characteristics of traditional plants but that derive the greater availability of water in the tank by lifting electro (with pumps or with the same turbine manufacturing). This type of system consists of two end tanks, placed at different heights, connected by the artifacts of a typical hydroelectric plant: during the day of highest demand (peak), the user water stored in the upper reservoir is used to the production of electricity; in times of low demand (at night) the same is raised to the upper reservoir. In this way the use of electricity to pump water into the upper reservoir is returned almost entirely in the form of a higher quality because back in the hours of greatest demand.
The spread of a large number of these plants, although medium-sized and small, on the one hand would allow greater retention of water in the area, which is always useful, and on the other side the opportunity to mitigate flooding in the case of heavy rainfall the reservoirs would be filled without the need to pump water from downstream to upstream, in these cases there is a net gain of electricity. Hydroelectric plants a tank or storage are currently the best system of energy storage, if such systems were adopted this would allow a larger number on the one hand the need for fewer power plants, which are now necessary to meet the needs of the tip, from ' On the other hand would allow maximum efficiency of power plants and also the same river plants and wind power systems, solar systems and derived from renewable energy sources in general.
