The whole world seems to global warming and climate change - human activities emit carbon dioxide - and thus the need to sell "green" causes planet earth. The Nobel Prizes were the UN IPCC (Intergovernmental Panel on Climate Change) and Al Gore has published a couple of years, the recent conference in Copenhagen (Follow-on to the Kyoto Climate Change Conference 1997), brought Obama Heads of State and Government of 192 countries according to its principles, promising severe financialRepairs to foreign countries.
Scientists have calculated that the carbon dioxide emitted by human activities, including the burning of fossil fuels, cement production, gas flaring, breathing difficulties and industrial operations totaled about 30 billion tonnes per year. They also estimated that cause volcanic eruptions, a candidate for the examination can usually between about 145 to 255,000,000 tons of CO2 emitted into the atmosphere each year, on average, both subaerial and submarine cracksand fans. This suggests that human activities may issue, perhaps 100 times more carbon dioxide emitted by volcanoes - seems to be a reasonable basis for the general concern: human activities affect the climate of planet Earth - and negatively - the cause of global warming .
However, the nature, in fact, a strong sense of humor - in the wake of the international furor admit guilt in Copenhagen by world leaders and President Obamain support of global warming - then the coldest winter will last decades. And now poised, with Obama EPA to impose severe restrictions on pollution and harsh financial penalties against American industry, is a volcanic eruption in Iceland that has devastated the airline industry, the closure of almost all flights across Europe for a week, with consequent cost implications, the major airlines (with no bail-out by governments in bankruptcy in May).
The reality of the most important naturalNatural disasters: This latest outbreak of the Icelandic volcano Eyjafjallajökull (or Krakatau, or earthquakes or tsunamis or hurricanes or economic cooling and warming of the ocean or atmosphere), should alert policy makers that the Earth is vast and complex and that feeling good, simplistic ideologies dictate industrial and financial restrictions on repairs (EPA cap and trade or the Bill) can great economic loss in the national pursuit of a noble cause ("greening" Planet Earth) - butmay bring little benefit.
Within the first 72 hours after the eruption of the volcano Eyjafjallajökull, reported the Icelandic Institute of Geosciences of the average flow of ash and 750 tonnes per second or 65 million barrels a day - equivalent to the normal annual average flow - and only the early days. to reach the source of ash more than seven miles in the sky, some 100,000 flights were canceled, tens of millions of passengers stranded, significant failure of the main airlinesOpportunities. There is also a limitation of this eruption Icelandic appendix - a similar eruption in Iceland in 1821 lasted for 13 months!
justified in view of the volcanic eruption in Iceland, a look at the causes of global warming and climate change - as opposed to activities of human nature - it seems. The summer of 1816 as one of the coldest on record, which will be studied by many researchers forecast. The year is called "year without summer", is also known as "Poverty Year", due towidespread destruction of crops. Gravity anomalies of climate destroyed during the summer crops in northern Europe sank the northeast U.S. and eastern Canada and the cause of global average temperature sufficient to considerable losses to agriculture worldwide.
Of great interest were the environmentalists to unusual events that had before the summer of 1816: the year before the eruption of Tambora volcano 13,000 feet tossed in Indonesia it is estimated that 37-100cubic miles of fine dust, slag and ash more than 15 miles into the atmosphere. Estimates of deaths was around 10,000, with the explosion heard 970 miles away. Meteorologists believe that the eruption causes the greatest amount of volcanic dust ejected into the atmosphere of history. Furthermore, the atmosphere was already past eruptions of other volcanoes, volcanoes, Mayon and Luzon in the Philippines in 1814, and the Soufriere volcano on St. Vincent in the pollutedCaribbean in 1812. The powder combined all these eruptions and remained in the stratosphere - to protect the earth from the sun - thereby avoiding the heat from the earth - that is reducing the temperature of the earth.
The most likely cause of climate change seriously seems to be the influence of volcanic origin. Proponents note that many large volcanic eruptions in 1816 and Soufrière Saint Vincent in 1812: Mayon and Luzon in the Philippines in 1814, Tambora in Indonesia inThe 1815 Tambora eruption has been estimated that the most violent in historical times believed the explosion cursed 150-180 cubic kilometers of material into the atmosphere. (For comparison, the infamous eruption of Krakatau in 1883, only 20 cubic kilometers of material ejected into the air - and yet affected sunsets worldwide for several years after).
The seemingly reasonable scientific "immediate cause of the drastic climate change in 1816, so that thethe theory of volcanic influence climate: strong increase in volcanic activity caused huge amounts of ash and dust are blown and trapped high in the atmosphere, thereby reflecting an increase in solar radiation (instead of absorption on the surface) that temperatures available worldwide on Earth.
Frail man and his activities seem trivial and insignificant compared to the playfulness and the power of nature and the complexity and vastness of the planet earth, andprimary influence of our sun.
