You Can Help Fight Global Warming

You Can Help Fight Global Warming
Many efforts are being made by various nations to cut down the rate of global warming. One such effort is the Kyoto agreement that has been made between various nations to reduce the emissions of various green house gases. Also many non profit organizations are working for the cause. Al Gore was one of the foremost U.S. politicians to heave an alarm about the hazards of global warming. He has produced a significantly acclaimed documentary movie called "An Inconvenient Truth," and written a book that archives his advice that Earth is dashing toward an immensely warmer future. Al Gore, the former vice president of United States has given various speeches to raise an awareness of global warming. He has warned people about the ill effects of Global warming and its remedies.
But an interesting side of the global warming episode is that there are people who do not consider global warming as something that is creating a problem. Skeptics of global warming think that global warming is not an ecological trouble. According to the global warming skeptics, the recent enhancement in the earth's average temperature is no reason for alarm. According to them earth's coastlines and polar ice caps are not at a risk of vanishing. Global warming skeptics consider that the weather models used to establish global warming and to forecast its impacts are distorted. According to the models, if calculations are made the last few decades must have been much worse as compared to actually happened to be. Most of the global warming skeptics believe that the global warming is not actually occurring. They stress on the fact the climatic conditions vary because of volcanism, the obliquity cycle, changes in solar output, and internal variability. Also the warming can be due to the variation in cloud cover, which in turn is responsible for the temperatures on the earth. The variations are also a result of cosmic ray flux that is modulated by the solar magnetic cycles.
Global Warming Skeptics
The global warming skeptics are of the view that the global warming is a good phenomenon and should not be stopped. There are various benefits of global warming according to them. According to the skeptics, the global warming will increase humidity in tropical deserts. Also the higher levels of carbon dioxide in the atmosphere trigger plant growth. As predicted, due to the global warming the sea levels will rise. But this can be readily adapted. Another argument of global warming skeptics is that earth has been warmer than today as seen in its history. The thought is that global warming is nothing to get afraid of because it just takes us back to a more natural set of environment of the past. Animals and plants appeared to do just fine in those eras of warm climate on the earth. According to few skeptics, the present chilly climate on the earth is an abnormality when judged over the geographical scale. Over geologic time, the earth’s mean temperature is 22 degrees C, as compared to today's 15.5 degrees C.

Global Warming Causes

Global Warming Causes As said, the major cause of global warming is the emission of green house gases like carbon dioxide, methane, nitrous oxide etc into the atmosphere. Gasoline Causing Global WarmingThe major source of carbon dioxide is the power plants. These power plants emit large amounts of carbon dioxide produced from burning of fossil fuels for the purpose of electricity generation. About twenty percent of carbon dioxide emitted in the atmosphere comes from burning of gasoline in the engines of the vehicles. This is true for most of the developed countries. Buildings, both commercial and residential represent a larger source of global warming pollution than cars and trucks.
Building of these structures require a lot of fuel to be burnt which emits a large amount of carbon dioxide in the atmosphere. Methane is more than 20 times as effectual as CO2 at entrapping heat in the atmosphere. Methane is obtained from resources such as rice paddies, bovine flatulence, bacteria in bogs and fossil fuel manufacture. When fields are flooded, anaerobic situation build up and the organic matter in the soil decays, releasing methane to the atmosphere. The main sources of nitrous oxide include nylon and nitric acid production, cars with catalytic converters, the use of fertilizers in agriculture and the burning of organic matter. Another cause of global warming is deforestation that is caused by cutting and burning of forests for the purpose of residence and industrialization.
Annual Greenhouse Gas EmissionsGlobal Warming is Inspiring Scientists to Fight for Awareness
Scientists all over the world are making predictions about the ill effects of Global warming and connecting some of the events that have taken place in the pat few decades as an alarm of global warming. The effect of global warming is increasing the average temperature of the earth. A rise in earth’s temperatures can in turn root to other alterations in the ecology, including an increasing sea level and modifying the quantity and pattern of rainfall. These modifications may boost the occurrence and concentration of severe climate events, such as floods, famines, heat waves, tornados, and twisters. Other consequences may comprise of higher or lower agricultural outputs, glacier melting, lesser summer stream flows, genus extinctions and rise in the ranges of disease vectors. As an effect of global warming species like golden toad, harlequin frog of Costa Rica has already become extinct. There are number of species that have a threat of disappearing soon as an effect of global warming. As an effect of global warming various new diseases have emerged lately. These diseases are occurring frequently due to the increase in earths average temperature since the bacteria can survive better in elevated temperatures and even multiplies faster when the conditions are favorable. The global warming is extending the distribution of mosquitoes due to the increase in humidity levels and their frequent growth in warmer atmosphere. Various diseases due to ebola, hanta and machupo virus are expected due to warmer climates. The marine life is also very sensitive to the increase in temperatures. The effect of global warming will definitely be seen on some species in the water. A survey was made in which the marine life reacted significantly to the changes in water temperatures. It is expected that many species will die off or become extinct due to the increase in the temperatures of the water, whereas various other species, which prefer warmer waters, will increase tremendously. Perhaps the most disturbing changes are expected in the coral reefs that are expected to die off as an effect of global warming. The global warming is expected to cause irreversible changes in the ecosystem and the behavior of animals.
Global Warming ProjectionsA group of scientists have recently reported on the surprisingly speedy rise in the discharge of carbon and methane release from frozen tundra in Siberia, now starting to melt because of human cause increases in earth’s temperature. The scientists tell us that the tundra is in danger of melting holds an amount of extra global warming pollution that is equivalent to the net amount that is previously in the earth's atmosphere. Likewise, earlier one more team of scientists reported that the in a single year Greenland witnessed 32 glacial earthquakes between 4.6 and 5.1 on the Richter scale. This is a disturbing sign and points that a huge destabilization that may now be in progress deep within the second biggest accretion of ice on the planet. This ice would be enough to raise sea level 20 feet worldwide if it broke up and slipped into the sea. Each day passing brings yet new proof that we are now in front of a global emergency, a climate emergency that needs instant action to piercingly decrease carbon dioxide emissions worldwide in order to turn down the earth's rising temperatures and avoid any catastrophe.
It is not easy to attach any particular events to global warming, but studies prove the fact that human activities are increasing the earth’s temperature. Even though most predictions focus on the epoch up to 2100, even if no further greenhouse gases were discharged after this date, global warming and sea level would be likely to go on to rise for more than a millennium, since carbon dioxide has a long average atmospheric life span.

What is Global Warming?

The average facade temperature of the globe has augmented more than 1 degree Fahrenheit since 1900 and the speed of warming has been almost three folds the century long average since 1970. This increase in earth’s average temperature is called Global warming. More or less all specialists studying the climate record of the earth have the same opinion now that human actions, mainly the discharge of green house gases from smokestacks, vehicles, and burning forests, are perhaps the leading power driving the fashion. Melting Glaciers
The gases append to the planet's normal greenhouse effect, permitting sunlight in, but stopping some of the ensuing heat from radiating back to space. Based on the study on past climate shifts, notes of current situations, and computer simulations, many climate scientists say that lacking of big curbs in greenhouse gas discharges, the 21st century might see temperatures rise of about 3 to 8 degrees, climate patterns piercingly shift, ice sheets contract and seas rise several feet. With the probable exemption of one more world war, a huge asteroid, or a fatal plague, global warming may be the only most danger to our planet earth.

7 Reasons Why the World Will End in 2012

7 Reasons Why the World Will End in 2012 is it true or not

December 21st, 2012! The real truth of what's to happen!

December 21st, 2012! The real truth of what's to happen! or not?

Planetary Alignment on December 21 2012

However, there are others who contend that the end of the world 2012 prophesy actually refers to a very rare planetary alignment that will occur during the winter solstice on december 21 2012. At this time the entire Milky Way (including the earth and the sun) will align at a point that is known as the galactic equator. This alignment is so rare that it only happens every twenty five thousand years. It is thought that this rare planetary alignment could signal a shift in the magnetic poles. This polar shift has happened before in the distant past, and if it were to happen now it would cause massive destruction across the globe. Some claim that the reason the Mayan long calendar ends on this exact date is that something is going to happen in combination with this alignment, the introduction of Nibiru, and the solar flares. It can’t be a coincidence that all of these things are scheduled to happen at the same time that the Mayan calendar is set to come to its conclusion, can it?
If nothing else the 2012 end of the world prophesy that is brought about by the Mayan calendar does bring with it several questions about this culture’s knowledge of celestial events and happenings that they could not have possibly understood, let alone have mapped out to the extent that they did. Their understanding of the solar system, the planetary alignments, and other important events is something that cannot be easily explained or understood by most people who have studied this rare Mayan philosophy.
The end of the world 2012 scenario is one that frightens many people, but this does not have to be the case. If you are interested in finding out more about the theories and philosophies that the 2012 doomsday prophesy is founded on, then you visit the link below to find out more about the end of the world and what you can do to help your family survive any number of disasters. On top of this you can get a complete three hundred and sixty degree view of the processes of the 2012 countdown, including a special bulletin that will keep you up to date on everything that is related to this upcoming date and the disastrous implications it brings with it. So, if you are someone who is looking to make sure that they stay ahead of the danger and keep on top of new developments on the end of the world 2012, then this site is the perfect thing to keep you informed and prepared to december 21 2012.

The Truth About Planet X – Nibiru

Something else that has been considered is the belief that the 2012 end of the world will come to Earth not through some planetary force outside of our galaxy, but through the power of our own sun. Some who have studied the timing of the 2012 prophesy and combined this knowledge with an understanding of the solar system believe that the end will come via a large solar flare. This flare will come about because of the infiltration of the orbits of the planets in our solar system by an outside orbiting planet that the Sumerians and the Babylonians referred to as Nibiru, and is sometimes referred to by modern scientists as Planet X. Those who subscribe to this theory believe that Nibiru only orbits through our system once every three thousand six hundred years.
In addition to this, these cultures believed that there were a race of people who lived on Nibiru that were known as the Anunnaki. According to their creation mythology this superior race of beings came to Earth and genetically engineered human beings. They did this because they needed to get gold ore from our planet in order to help save their own environment. The humans that they created helped them by mining the gold from Africa. The basis for this mythology was found in ancient writings that were recently uncovered in relation to the ancient Sumerians, and they documented this creation in detail in their writings. If they are correct, then the end of the world 2012 that is depicted in the Mayan calendar will also coincide with the return of the Anunnaki. In essence, it would be the return of our creators, and this is also something that is closely linked in with the belief that the Mayan calendar signals the forthcoming Apocalypse.
According to this 2012 end of world philosophy, when this planetary body re-enters our system it will cause massive disruptions in the orbits of Jupiter, Uranus, Venus, and Earth. When Nibiru crosses our orbit they believe that it will cause the gases in Jupiter to ignite because it will get too close to the sun and the precarious balance that keeps its gas structure in check will be lost, therefore causing Jupiter to turn into a secondary sun. In combination with this, the solar flares that are released from the sun on a naturally reoccurring cycle are set to peak during the year 2012. It is believed that this occurrence in combination with the cycle of Nibiru will cause a massive amount of damage to the planet on a level that has never been seen before.

December 21 2012 Predictions – The End of The World 2012?

Until a couple of years ago there were not that many people who were acquainted with the end of the world 2012 prophecy that was put forward by many scholars who studied the end of the Mayan long calendar. This Long Count calendar has lasted for five thousand one hundred and twenty five years, and although the end of the calendar leads to many different interpretations, one of the most popular is the belief that at the end of this cycle the world (or humanity’s existence) will come to an abrupt end on December 21 2012. Is the world going to end in 2012?
In order to fully understand the 2012 end of the world predications, then you should first understand the calendar that is at the center of this controversy. The current cycle, or baktun, of this calendar began on August 13th, 3114 B.C. This marked the end of the last period and the beginning of the current one. The baktun that we are currently living in is the thirteenth, and the end of this cycle is one that has been considered to have a large level of importance to the Mayan people, which is why so many people have come to the conclusion that this cycle’s end is one that will mean the end of the world as we know it.
While there is no definite proclamation of how the end of the world 2012 predictions will happen, those who have studied this calendar claim that the long calendar was created in order to correspond with a long term astronomical prediction by the Mayan people. This has led some to believe that this end of the world scenario will play out in a manner that has something to do with something from beyond this world. While this correlation to something that is going on in outer space is not a definite thing, for some it comes from a basic understanding of Mayan culture and their unique understanding of astronomical phenomena and planetary alignments.

Hubble Space Telescope History

In 1962, the USA's National Academy of Sciences recommends building a large space telescope. In 1977, Congress votes to fund the project and construction of Hubble Space Telescope begins.
Construction of Hubble Space Telescope was completed in 1985. The launch of Hubble was delayed due to the 1986 Space Shuttle Challenger disaster. Hubble was launched on the space shuttle on April 25, 1990. It was named after Edwin Hubble.

Within days Hubble
was sending back pictures that were out of focus. NASA discovered a major flaw in the giant mirror. The giant mirror was too flat on one edge by 1 / 50th of the width of a single human hair.

In December, 1993, the Space Shuttle Endeavor captured and modified the Hubble Space Telescope by adding a camera to correct problems with the telescope's primary mirror.The second servicing mission was in february 1997. Astronauts exchanged some of Hubble's instruments and added new blankets to keep Hubble warm.
On October 1997, NASA decided to extend Hubble's operations from 2005 to 2010.On November 13, 1999, a fourth gyroscope on Hubble fails. The Hubble shuts down to await a repair mission since it can no longer aim. Space Shuttle mission repairs the Hubble and upgrades it.
