Summer in future will be hotter and hotter
Tuesday, 07 June 2011 18:12
According to scientists from Stanford University, the average summer temperatures in the coming years will become higher and higher.

After analysis of about fifty of computer climate models that are based on historical data of weather stations from all major parts of the world, it was concluded, that the particularly strong increase in summer temperatures will affect the mid-latitudes - Europe, North America, Central Asia and China. Already this year in China, there is drought, the most powerful in recent years of meteorological observations. But residents of the tropics, too will expect an increase in average temperature, but in the longer term.

According to scientists, the increase in summer temperatures may have an impact on human health and agricultural development. As an example was given of the summer heat in 2003 in Europe, when affecting 40,000 people. The analysis found, that across the Northern Hemisphere as a whole in 2010, the average temperature has risen to 0,963 ° C, which is never seen in the last hundred years of regular meteorological observations.

In Russia, the country as a whole, summer 2010 was the hottest: in May and July 2010 the average air temperature has reached the absolute maximum of 120 years of regular Russian meteorological observations, which are conducted since 1891. But because of the huge size of Russia, climate change will occur is very uneven. If in the northern regions of Russia are expected surplus of fresh water due to an anticipated increase in rainfall, the country's southern regions, particularly in the Stavropol and Krasnodar regions, Kalmykia, Volgograd region problems with fresh water will become more acute. Due to changes in rainfall, grain yields in the fall by 10-13 percent, and in southern Siberia - even at 25 percent. But upon further warming will increase area of cultivation of heat-loving crops, in some southern regions of Russia in 30 years will be even grow sub-tropical crops. One positive point in the future warming- uncomfortable zone will be shifted by at least 60 kilometers to the north. Permafrost zone, which occupies about 58 percent in Russia in 30 years will move into western Siberia by 200 km to the north. It already can damage the stability of many buildings and structures, built in these areas, taking into account the factor of permafrost, especially the numerous gas and oil pipelines, which supply minerals from Siberia to Europe and China. As a result, the threat of destruction will be exposed to most of the houses in Yakutsk, Vorkuta, Tiksi, Norilsk and other cities in permafrost regions.

By 2040, in the countries of Southern Europe, Latin America and much of Asia, the Middle East, and Africa expected drought. The worst scenario that could happen, suggests that there will be large-scale drought in the country where most of the food - these are the countries of North America, Europe and Asia. As a result of a decline in rainfall will be drying up of rivers and depletion of fresh water. This will have reduced food supplies, famine and epidemics, as well as uncontrolled migration of local people from areas of distress. Worldwide tougher increase international tension, there may be war for power and water sources. At the same time in areas with traditionally dry climate (especially in Australia), rainfall could increase dramatically, and increase the number of floods that cause the reduction of use of agricultural land is not suited to such an abundance of moisture. In 2010 and early 2011, Australia has experienced a number of major floods, which resulted in substantial property damage. Thus in these areas is also expected shortages of food, but an abundance of fresh water.

And it's not just a prediction, it is an alarm for the world, accustomed to a gradual change in climate and do not pay much attention to small changes in climate.

Hundreds of dead penguins washed up on the coast of Uruguay- the story of the dead birds continues
Wednesday, 08 June 2011 12:24
 

Deputy Head of Public Relations Department of the Navy of Uruguay, confirmed on 7 June 2011 that about 600 Magellanic penguins were found dead on a beach in La Paloma, about 200 km east of the Montevideo, Uruguay. In addition to the penguins, on the beach have been found dead seabirds and turtles.

This story has already attracted the attention of many media, as many remember the unexplained deaths of thousands of birds in 2010 and 2011 in different parts of the world, and the Penguins are marine birds.

Penguins live practically in many seas of the Southern Hemisphere: near Antarctica, near New Zealand, near Australia, South Africa, as well as along the entire coast of South America, from the Falkland Islands to Peru and the Galapagos Islands near the equator. Penguins prefer low temperatures, so in tropical penguins appear only with cold Humboldt Current, near the west coast of South America and the Benguela Current, which arises from the Cape of Good Hope and the surrounding west coast of South Africa. Most penguin species live between 45 ° and 60 ° of south latitude, but the greatest concentration of species of penguins found in Antarctica and nearby islands.

The main area of the Magellanic penguin located near coast of Patagonia, Tierra del Fuego, the islands of Juan Fernandez and the Falkland Islands. Magellanic penguins have been spotted as far north as Rio de Janeiro and the southern part of Peru. World population of Magellanic penguin population is of about 1.8 million pairs, of which one hundred thousand nests in the Falklands, 900 000 nests in Argentina, and about 800 thousand nests in Chile. During the wintering, Magellanic penguins migrate widely, reaching the coast of Brazil to 10-15 ° of south latitude. Magellanic penguins can live to 20 years, but natural predators for magelanovyh penguins are leopard seals, sea lions and whales. From the human threat comes from the fishermen and oil pollution. The number of colonies of Magellanic penguins in the Falkland Islands began to fall heavily, since the start of commercial fishing on fish and krill, but such a reduction of Magellanic penguins is not happening in Argentina and Uruguay, where the colony of Magellanic penguins are protected from commercial fishing.

Therefore, every year large groups of Magellanic penguins migrate northwards towards the coast of Argentina and Uruguay, to find new places to feed and then back again. Over the past few years, on the coast of Uruguay, was found dead penguins, but have never found such a large number of dead penguins. In addition, earlier found dead penguins have always been mired in oil, as is well known, that the oil binds the fat on the feathers of penguins and then the penguins are dying from hypothermia.

Founded on June 7, 2011 hundreds of dead penguins are not smeared with oil, and researchers are lost in the assumptions- that could cause the death of penguins in a vast, previously not observable quantities. After that, when with location of dead penguins near the town of Piriapolis in Uruguay have found bags of pesticides, with inscriptions in Portuguese, it was assumed, that penguins have died from poisoning, but until laboratory tests have not confirmed this.

In addition, some scientists from Argentina had already made the assumption, that the main reason for such a mass death of the penguin- is the physical exhaustion, due to the fact, that fish shoals have changed the usual areas of their habitat, due to redirection of ocean currents due to global warming and penguins do not physically have enough food for sustenance. This version says two things: first- this year, the Magellanic penguins too early to start migrating to the coast of Uruguay, usually migration begins in late June to early July, and secondly- a year ago on the coast of Brazil has already thrown heavily depleted, but living penguins.

Apparently in 2011, the situation with the ocean currents, has further deteriorated and it is quite possible, that the redirection of ocean currents can cause climate changes.

Melting of permafrost could lead to the most global catastrophe in Earth's history
Tuesday, 16 August 2011 08:48
http://hainanwel.com/en/unusual-world/8 ... frost.html 

According to Russian news agency RIA-Novosti, the team of researchers, led by Charles Coven, developed a new model of melting of permafrost. An analysis of the new model showed that, due to the melting of permafrost in areas in the polar latitudes of the Arctic- in the Earth's atmosphere can be allocate of 25-85 billion tons of gases per year (in terms of carbon). According to RIA-Novosti, the whole ground in permafrost regions will allocate 25-85 billion tons of carbon at a certain average value of 62 billion tons of carbon, because of this ground in permafrost regions can move from the absorption of gases (measured in 68 billion tons) - to their release. These fantastic estimates suggest a start in the near future, such a global catastrophe, compared with which even a collision with a large meteorite, and nuclear war, may seem a trifle. If the above estimates are correct, then it follows from the fact that the soil near-polar regions of Earth will cease to absorb carbon dioxide and it will allocate to the atmosphere as a result of global greenhouse effect occurs, which could lead to raising the average temperature on Earth at least 10 degrees Celsius, because of this life in the regions at the equator and in the equatorial regions of the Earth will become impossible, these regions become scorched desert. Cause mistrust and figures estimated emissions of greenhouse gases to tens of billions of tons, and it is well known that even the biggest volcanic eruptions, which result in greater crop failures in the past, estimated at several hundred times weaker. For example, when volcano Laki in 1783 stood out "only" 90 million tons of greenhouse gases. Therefore, estimates of emissions to 25-85 billion tons of carbon can be greatly exaggerated, have nothing to do with the actual situation in the polar regions of Earth.

Climate catastrophe may be in next 5 years
Thursday, 10 November 2011 10:23

http://hainanwel.com/en/unusual-world/1 ... rophe.html

The International Energy Agency issued a warning, that the world faces an increasing number of extreme weather, if in the next five years will not be taken ways, that reduce fossil fuel use. The transition to new energy sources is the political will in industrialized countries, as in the world there are technologies, that make up demand for energy by using alternative energy sources. However, this transition is not beneficial to all, as industrialized countries, as well for countries, that produce raw materials, that may lose their main source of its prosperity.

Drought destroyed the Mayan civilization- VIDEO

Friday, 09 November 2012 18:00


In the Science magazine was published an article of a group of scientists from the UK, Switzerland and the United States, under the leadership of Kenneth Douglas, Professor of Anthropology from University of Pennsylvania, that the principal cause of death of the Mayan civilization was a drought. According to the Science, as a result of isotopic analysis of stalagmites of two thoUSAnd years old, that were found in caves in the territory of Mayan civilization, it became possible to reconstruct the climatic conditions in the entire history of Mayan civilization. According to Douglas Kenneth, from the analysis of stalagmites from caveYoke Balum in the south of Belize, and in other caves - were found a strong correlation between climatic conditions and periods of prosperity and decline of the ancient Mayan civilization- with heavy weather rainfall during the 450-660, has led to rapid population growth and urban sprawl in the valleys of the Maya of Central America, and the lack of water caused a decline in agriculture of Maya. But the most severe drought since 1020 to the 1100 had a strong influence on the civilization of the Maya, THE VIDEO: http://hainanwel.com/en/unusual-world/2 ... ation.html

Coffee trees may disappear in the next 70 years- VIDEO

Friday, 09 November 2012 19:22


Aaron Davis and Justin Moat, representatives of the Royal Botanic Gardens Kew Society (RBGK), United Kingdom reported, that the Arabian coffee trees may disappear in Africa until to 2080, due to climate changes. Aaron Davis and Justin Moat created a special computer model, that forecasts the state of Arabian coffee trees in Africa until 2080, based on the climate trends over the past 100 years. According to this computer model, in some regions of Africa will disappear from 65% to 100% of coffee trees, and that if do not take into account the scale of felling of trees. The scale felling of trees, which are produced in the high forests of Ethiopia and South Sudan- a climate changes can happen more quickly, than is accounted for in a computer model of the representatives of the Royal Botanic Gardens Kew Society (RBGK), THE VIDEO: http://hainanwel.com/en/unusual-world/2 ... ppear.html

Bark beetles have caused a warming of the climate in Canada in 21 th century- VIDEO

Monday, 26 November 2012 07:32


In the Nature Geoscience magazine appeared an article of the group of ecologists from the University of California at Berkeley, USA, under the guidance of Holly Maness, that the sharp increase in the number of bark beetles Dendroctonus ponderosae, which destroyed much of the forest in Western Canada - was the major cause of sudden warming in western Canada in the 21 th century. According to Holly Maness, in recent years, forests in British Columbia and other provinces in Western Canada seen a massive attack by bark beetles Dendroctonus ponderosae, which have ceased to fulfill its role nurses of forest and began to destroy healthy trees with old trees. With the help of satellite images, which were obtained by climatic MODIS satellite from 2000 to 2010, it was found, that the highest temperatures during the day are observed in those parts of the forest, where a many trees were killed by bark beetles Dendroctonus ponderosae, which generally has to reduce emissions of steam by 19% and increased heating of the soil by 8% on those parts of the forest. In a more global scale, this resulted in an increase of average temperatures in western Canada by one degree of Celsius, THE VIDEO: http://hainanwel.com/en/unusual-world/2 ... rming.html

Scientists warn about new Global Flood-VIDEO

Wednesday, 28 November 2012 10:35


According to BBC, at the ongoing UN conference in Qatar, dedicated to the fight against climate change, German scientists from the Potsdam Institute for Climate Change reported, based on new data from satellite observations of sea level, that over the past 20 years, sea level has increased by an average of 3 2 millimeters per year, which is about 60% faster, than previously thought of UN experts. Scientists from the Potsdam Institute for Climate Change confirmed the presence of global warming, as the process of increasing global average temperature is fully consistent with the UN forecast, that contrary to the view of skeptics, who believe, that the threat of global warming is greatly exaggerated, THE VIDEO: http://hainanwel.com/en/unusual-world/2 ... flood.html

Climate change is cause of the appearance of giants among feathered dinosaurs- VIDEO

Thursday, 29 November 2012 17:28


In the Proceedings of the Royal Society B magazine appeared an article of a group of scientists from the University of North Carolina in Raleigh, USA, under the guidance of Lindsay Zanno, that the generally accepted theory about the cause of gigantism in feathered dinosaurs, was the transition to a vegetarian diet - is wrong. According to Lindsay Zanno, diet of feathered dinosaurs was not the determining factor in the growth of their mass, most likely, that climate change caused an increase in the mass of feathered dinosaurs, which has led to the emergence of these feathered dinosaurs-giants (see the video). This is confirmed by the study of anatomy and eating habits of 47 giant feathered dinosaurs, that lived on Earth in the Cretaceous period, in particular, the evolution of the three groups of feathered dinosaurs, THE VIDEO: http://hainanwel.com/en/unusual-world/2 ... saurs.html

2012 is one of the warmest years ever recorded- VIDEO

Wednesday, 28 November 2012 17:02


In the annual report of the World Meteorological Organization (WMO) stated, that in 2012 the average temperature, on the results of the first ten months, is included in the Top-10 of warmest years in the history.As stated in the report of the World Meteorological Organization, which was presented at the UN conference on climate change, the period from January 2012 to October 2012 was in ninth place in the list of the warmest years in the history of meteorological observations since 1850. 2012 was the warmest year in the history of the entire continental United States (excluding the territories of Alaska and Hawaii) and in southern Europe, north-west of Asia and much of the Pacific Ocean. On average in 2012, the global surface temperature was about 0.45 degrees higher, than the average temperature from 1961 to 1990, which stood at 14.2 degrees Celsius. According to the WMO Secretary, despite the average strength of oceanic phenomenon La Nina, which is characterized by an abnormal cooling of the surface water in the tropical Pacific, in 2012 was stated a record of low minimum sea ice in the Arctic, it was 18% below of previous anti-record in 2007, THE VIDEO: http://hainanwel.com/en/unusual-world/2 ... -year.html
