What are the Causes of Global warming - 0 views

  • It’s a scientifically proven “Fact,” that over the past century, our planet has slowly been warming up. Since the beginning of the 20th century, the average temperature around the world has gradually risen by one degree fharenheit.While this minimal warming might not seem all that significant, the truth is, according to Climatic Specialists all around the globe, the over-all impact will most certainly prove to be devastating if this continual warming process is not somehow ebated. Scientists have been busily searching and studying in order to determine precisely what the primary, “key factors” are behind this progressive “heating up” process. Here’s what they have come up with thus far:
  • The Main Causes of Global Warming (Manmade & Nature) To the surprise of many out-spoken environmentalists, it, in fact, turns out mankind and technology actually aren’t the only significant causes of global warming. There actually are a wide variety of 100%, ‘all natural” causes, ranging from volcanic eruptions, solar radiation and natural thawing of the Earths “permafrost” and glaciers. In other words, the planet’s temperature, just like most other things in life and natural science, simply tends to fluctuate through natural, rhythmic, “ebbs and flows” and highs and lows that are caused and by sources within the planet itself, as well as the vacillating environment of  the solar system and universe that we are passively passing through. However, before we start to get too comfortable and confidently assume that we as human beings are officially “off the hook,” the fact remains that several “man made” causes play a significant role in our current, global warming trend. Welcome to the Greenhouse. Yes, the “Greenhouse” effect may very well be the most popular new term utilized in environmental circles and it’s time people really begin to understand exactly what it is, what it does and what we can do about it.
  • What Are Greenhouse Gases Greenhouse gases, being lighter than air, naturally rise up the outer limits of the earth’s atmosphere and then settle there, creating an impenetrable barrier that traps heat from being able to escape into space, holding it hostage within our environment and warming the temperature in the process. It is feared that unless we change our ways, getting smarter about our greenhouse gas emissions, they could increase an addition 5 to 9% over the next hundred years and lead to some very serious problems maintaining a comfortable and healthy life on Earth. So where does this greenhouse gas come from and what other culprits are responsible for our “global warming” problems?
  • ...4 more annotations...
  • Carbon Dioxide from Power Plants: Nearly 40% of our carbon dioxide emissions come directly from the process of burning ‘fossil fuels” in order to generate electricity. Of that almost 40% of our CO2 emissions directly attributed to generating power, over 90% of it comes from the burning of coal. Coal emits 25% more carbon per “unit of energy” than oil and 70% more carbon than natural gas. Carbon Dioxide from Automobiles: Approximately 1/3 of the carbon dioxide emissions released into our environment comes from the burning of gasoline in internal-combustion engines of automobiles, buses, motorcycles, “SUVs,” recreational vehicles, trucks and of course, motor sports. As motor sports (racing) continue to grow in popularity, the huge amount of fuel being used continues to grow annually. Just NASCAR alone, which is only one of numerous racing associations, admits that it burns over 1 million gallons of gas per year when you combine the gasoline used for the racing, trials, practice runs, etc. That doesn’t even take into account the gas spent traveling, hauling the cars, equipment, team and tools for each car back and forth to the track
  • Carbon Dioxide from Airplanes: The United Nation's Intergovernmental Panel on Climate Change estimates that aviation currently is responsible for just under 5% of global warming and that the figure could very well rise to approximate 15% by the year 2050. Carbon Dioxide from Buildings: Scientists claim that something so very mundane as the regular maintenance, temperature control and cleaning of buildings structure actually account for nearly 12% of carbon dioxide emissions. Methane: CO2 is not the only “Greenhouse Gas” that the planet is contending with these days. While carbon dioxide may be primary greenhouse gas, methane actually is 20 times more effective as CO2 at trapping heat in the Earths atmosphere. Emissions of methane released into our atmosphere have risen 145% in the last 100 years. Methane naturally occurs as part of the biological processes behind everything from bovine flatulence to the organic bacteria and sulfur’s commonly found in bogs, springs, and wells. Methane is a natural form of gas that is released in rice paddies as well as the composting and decomposition of organic matter. However, methane gas is also released during the processing and preparation of fossil fuels. Water Vapor: Believe it or not, something as natural and simple as “water vapor,” is the most prevalent and effective greenhouse gas on the planet. But, much of the cause behind its increasing levels entering the atmosphere is due to already increased global warming that has taken place, due to increased levels of CO2, methane as well as other greenhouse gases.
  • Water vapor is responsible for 2/3 of the heat currently trapped in the Earth’s atmosphere by all greenhouse gases. The hotter the atmosphere gets, the higher the level of “relative humidity” which holds the heat in even better. Nitrous Oxide: Yet another of the infamous “Greenhouse Gasses, Nitrous oxide (N2O) is a colorless, non-flammable gas with a slightly sweet odor. Most commonly known as “laughing gas” and used as a medical anesthetic, nitrous oxide is naturally produced by oceans and rainforests. Nitrous oxide is naturally broken down in the atmosphere through chemical reactions that occur with sunlight. Some of the most prevalent “man-made” sources of nitrous oxide are agricultural fertilizers, nylon, catalytic converters and nitric acid, along with the burning of organic matter. Deforestation: According to NASA, besides, human caused carbon dioxide emissions released into the environment, deforestation actually now is the 2nd most prolific cause of atmospheric CO2 influx. Deforestation is responsible for nearly ¼ of all carbon emissions entering the atmosphere. The planet cuts and burns nearly 34 million acres of trees each year, including millions of acres of “rainforest,” equal to the size of the entire country of Italy. The process of deforestation is “doubly” dangerous for the planet, because not only are we adding millions of tons of carbon dioxide into the atmosphere each year, but we are also wiping out the most effective cleansers of that deadly CO2 gas, the trees and plants that naturally “thrive” by consuming the carbon dioxide and offering up pure, clean, breathable oxygen as a free byproduct of the plant life cycle.
  • Melting Permafrost: Permafrost is the frozen soil throughout the arctic and sub-arctic regions, that contain all kinds of organic matter such as all kinds of frozen plants and animals that have been frozen solid and held inert for 30,000 years. Approximately 25% of the land mass of the Northern Hemisphere is “permafrost,’ or soil with a temperature of 32 degrees Fahrenheit (0 degrees Celsius) or less. Permafrost has acted like a jail cell for carbon, methane and other greenhouse gases for several thousand years, perhaps dating back to the last “Ice Age.” As glacial regions and permafrost begin to melt, the 50 billion tons of carbon that scientists estimate is held in a state on inactive, suspended animation under the frozen surface of the tundra will begin and continue to be released into our atmosphere, creating a greenhouse effect that would make the residents of the hottest and most humid tropical islands faint in mere minute. OK … so now we know the causes of Global Warming. It’s not ALL our fault, but we certainly have played a significant role in the decline of our environmental integrity. However, when you stop to think about it, that’s actually good news! You see, if we played a major role in creating, the problem, that logically means that we can also play a major role in SOLVING the problem! So just like in a good game of chess … it’s your move!

Natural Causes of Global Warming | What are They? - 0 views

  • Naturally Occurring Warming and Cooling ProcessesFirst, you should understand the primary natural causes of global warming:Volcanic EruptionsLarge volcanic eruptions can throw so much dust into the sky that the dust acts as a shield to solar radiation and causes a cooling trend in the atmosphere. You probably can’t remember such an eruption as they are rare and infrequent occurances.SunspotsChanges in the Earth’s solar radiation levels can have some impact on the Earth’s climate. Increased solar activity can cause short-term warming cycles on the Earth.The Wobbly EarthAs the Earth spins, it does not achieve perfect rotation. It actually wobbles slightly, thus alternately exposing the northern and southern latitudes to more and less solar radiation. This wobble in the Earth’s rotation has been causing changes in the temperature of the atmosphere for many millions of years.Humans Are a More Dangerous Cause of Global WarmingNow that you understand the natural causes, it is important to look at the human causes. While the changes in solar activity and the Earth’s rotation are natural events that have been occurring for many millennia, there is clear scientific consensus that global warming is real and that humans are part of the problem. [1] In fact, 1998-2007 was a record-breaking decade for the average surface temperature on earth, which cannot be explained by natural causes alone. [2]

NASA - NASA Study Predicts More Severe Storms With Global Warming - 0 views

  • Previous climate model studies have shown that heavy rainstorms will be more common in a warmer climate, but few global models have attempted to simulate the strength of updrafts in these storms. The model developed at NASA’s Goddard Institute for Space Studies by researchers Tony Del Genio, Mao-Sung Yao, and Jeff Jonas is the first to successfully simulate the observed difference in strength between land and ocean storms and is the first to estimate how the strength will change in a warming climate, including “severe thunderstorms” that also occur with significant wind shear and produce damaging winds at the ground. This information can be derived from the temperatures and humidities predicted by a climate computer model, according to the new study published on August 17 in the American Geophysical Union’s Geophysical Research Letters. It predicts that in a warmer climate, stronger and more severe storms can be expected, but with fewer storms overall.

Global Warming- Science - The New York Times - 0 views

  • Global warming has become perhaps the most complicated issue facing world leaders. Warnings from the scientific community are becoming louder, as an increasing body of science points to rising dangers from the ongoing buildup of human-related greenhouse gases — produced mainly by the burning of fossil fuels and forests.
  • In mid-February 2012, Secretary of State Hillary Rodham Clinton was expected to announce a new international effort focused on reducing emissions of common pollutants that contribute to rapid climate change and widespread health problems.
  • The United Nations conference on climate change in Cancún, Mexico, produced only modest achievements but ended with the toughest issues unresolved. The package that was approved, known as the Cancún Agreements, set up a new fund to help poor countries adapt to climate changes, created new mechanisms for transfer of clean energy technology, provided compensation for the preservation of tropical forests and strengthened the emissions reductions pledges that came out of the U.N. climate change meeting in Copenhagen in 2009.

  • At the 2011 conference delegates from about 200 nations gathered together in Durban, South Africa. One of the issues left unresolved was the future of the Kyoto Protocol, the 1997 agreement that requires major industrialized nations to meet targets on emissions reduction but imposes no mandates on developing countries, including emerging economic powers and sources of global greenhouse gas emissions like China, India, Brazil and South Africa.
  • In December 2011, the European Union’s highest court endorsed the bloc’s plan to begin charging the world’s biggest airlines for their greenhouse gas emissions from Jan. 1, 2012, setting the stage for a potentially costly trade war with the United States, China and other countries.
  • Airlines for America, an industry lobby group and one of the plaintiffs in the case, said that its members would be required to pay more than $3.1 billion to the E.U. between 2012 and 2020. It said its members would comply with the system “under protest,” but would also review options for pursuing the case in Britain’s High Court, which had referred the original complaint to the European court in 2009.
  • The United States has been criticized at the United Nations gatherings for years, in part because of its rejection of the Kyoto framework and in part because it has not adopted a comprehensive domestic program for reducing its own greenhouse gas emissions. President Obama has pledged to reduce American emissions 17 percent below 2005 levels by 2020, but his preferred approach, a nationwide cap-and-trade system for carbon pollution, was passed by the House in 2009 but died in the Senate the next year. United States emissions are down about 6 percent over the past five years, largely because of the drop in industrial and electricity production caused by the recession.
  • In March 2012, the E.P.A. unveiled a draft rule that would limit carbon dioxide emissions from new power plants to 1,000 pounds per megawatt-hour.
  • To open an avenue to companies still planning to build coal plants, for example, the E.P.A. said it would allow new ones to begin operating with higher levels of emissions as long as the average annual emissions over a period of 30 years met the standard.
  • Scientists learned long ago that the earth’s climate has powerfully shaped the history of the human species — biologically, culturally and geographically. But only in the last few decades has research revealed that humans can be a powerful influence on the climate, as well.  
  • That conclusion has emerged through a broad body of analysis in fields as disparate as glaciology, the study of glacial formations, and palynology, the study of the distribution of pollen grains in lake mud. It is based on a host of assessments by the world’s leading organizations of climate and earth scientists.

    Global Warming is one of the most importants because the ice in the poles are starting to melt and this can led to very big tsunamis and floods can start to happen
  •  
    The average surface temperature of earth has increased more than 1 degree Fahrenheit since 1900 and the rate of warming has been nearly three times the century-long average since 1970. Almost all experts studying the recent climate history of the earth agree now that human activities, mainly the release of heat-trapping gases from smokestacks, tailpipes, and burning forests, are probably the dominant force driving the trend.

      Nothing is completely certain in the science of global warming. Then the articles must have proof to make a statement
  • As with any field of scientific study, there are uncertainties associated with the science of climate change. This does not imply that scientists do not have confidence in many aspects of climate science. Some aspects of the science are known with virtual certainty1, because they are based on well-known physical laws and documented trends. Current understanding of many other aspects of climate change ranges from “very likely” to “uncertain.”

      global warming is heating the earth up making each day hotter melting the icebergs making the sea level rise.
  • Many things cause global warming.  One thing that causes global warming is electrical pollution.  Electricity causes pollution in many ways, some worse than others.  In most cases, fossil fuels are burned to create electricity.  Fossil fuels are made of dead plants and animals.  Some examples of fossil fuels are oil and petroleum.  Many pollutants (chemicals that pollute the air, water, and land) are sent into the air when fossil fuels are burned.  Some of these chemicals are called greenhouse gasses.
  • The greenhouse effect is when the temperature rises because the sun’s heat and light is trapped in the earth’s atmosphere.

  • When we throw our garbage away, the garbage goes to landfills.  Landfills are those big hills that you go by on an expressway that stink.  They are full of garbage.  The garbage is then sometimes burned.  This sends an enormous amount of greenhouse gasses into the air and makes global warming worse.
  • This layer is called the core.  Just like a core of an apple, it is in the middle.  Here there is a very high temperature, about 27,000,000°F.  This heat escapes out of this layer to the next layer, the radiative zone. This layer is cooler, about 4,500,000°F.   Gradually, the heat and light will pass through the convection zone at a temperature of around 2,000,000°F.  When it gets to the surface, the temperature is about 10,000°F.  Finally, the heat and light is sent into space.  This is called radiant energy (heat and light).  The radiant energy reaches the earth’s atmosphere.  As a result of this process we get light and heat.  When you pollute, you send chemicals into the air that destroy our atmosphere, so more heat and light cannot escape from the earth’s atmosphere.

    Global warming is when the earth heats up (the temperature rises). It happens when greenhouse gases (carbon dioxide, water vapor, nitrous oxide, and methane) trap heat and light from the sun in the earth's atmosphere, which increases the temperature. This hurts many people, animals, and plants. Many cannot take the change, so they die.
