It is becoming even more affordable to use alternative energy sources, as the equipment that is needed to make it work becomes more available, overcoming one of the biggest obstacles standing in the way of using cleaner energy. Did you know that you can even take advantage of tax incentives from the government that will give you cash back on your investment into alternative energy sources?

It is important to use these energy sources prudently, as they can be used to power just about anything in our lives. The renewable technologies for alternative energy today are able to meet all of our electricity demands. We all use and rely on a lot of electricity on a daily basis as a means of powering all of the gadgets that we use every day. The best way to meet the demand of consumers is to utilize alternative energy sources to power all the technology that is so prevalent in our daily lives.

Using these alternative sources also helps to save us money by using renewable energy, which costs less in the long run, and the planet by using safer, cleaner energy. You will see your power bills drop due to the lack of power grid energy that you need to use to power your home. However, even with all the options, alternative energy might not be enough to power everything in your home. But you could at least set up a back-up system until the energy is renewed and available.

You can just switch from your alternative energy source back to the electric source you are using at the moment. However, some homes might not ever use all the energy they generate and will end up with a surplus of unused energy. Some people use the amount of energy they need and then sell the excess energy to the power company to make extra money. Wouldn’t it be better to get a check from the power company than it would be to have to write them one?

All the money that you save on your energy bill can be used to purchase lots of other things. Economic studies show that the cost of gas and food are rising on almost a daily basis. Experts believe that this will continue for awhile in the coming months and years. You would really be doing your household budget a favor by saving money on your utility bill.

The energy that we use today is coming more and more from alternative energy sources as our demands for clean energy increase. Because of rising costs and a depletion of our limited supply of fossil fuels it is becoming more and more important to use alternative resources. There might be a different type of energy source that is ideal to where you live in the world. However, you can rest easy knowing that there are lots of researchers looking into new and unique alternative energy sources that will help us to meet the demands of our high-tech lifestyle.

Possible Causes: Nineteenth century scientists realized from geological evidence that the Earth had gone through many ice ages that alternated with ages of warmer climate. Much of the early research on global warming was a search for the cause of the ice ages. Scientists found that many small variables cause the Earth to warm and cool, but the main three causes are the Sun, particulates, and greenhouse gases.

The Sun’s output seems to have been reasonably stable over the last several million years. Satellite measurements over the last 30 years have shown that while solar radiation has declined ever so slightly during that time, the Earth continued to warm – so clearly changes in the Sun’s output is not the cause of the recent warming. The amount of sunlight the Earth receives does, however, depend on the Milankovitch Cycles. These cycles are small variations in the eccentricity, axial tilt, and precession of the Earth’s orbit cause the amount of sunlight the Earth receives to vary in predictable cycles. Ice core data shows that ice ages tend to occur in roughly 100,000-year cycles that match the timing of the Milankovitch cycles. The temperature changes observed, however, are much greater than would be caused by the changes in solar radiation alone. Though a clue to the cause of the ice ages, the Milankovitch Cycles are not the cause of the current warming. The cycles predict that a minor cooling trend, which began some 6,000 years ago, will continue for the next 23,000 years. The current warming trend is too rapid and in the wrong direction for the to Milankovitch Cycles to be the cause.

Particulates cause the Earth to cool by reflecting incoming sunlight back into space. The role of particulates in cooling the Earth became apparent in 1816 when ash from the explosive eruption of Mt.Tambora caused that year to be called “the year without a summer”, worldwide. The curious plateau in NASA’s temperature record from 1945 to 1975 was primarily caused by particulates from sources such as WW II, atmospheric nuclear testing, and increased industrialization. Research during the early 1970′s showed a huge increase in aerosol particulates from power production, factories, and vehicles – and some alarmists even speculated that they might cause another ice age. Particulates are visible and cause immediate health problems, so by 1980 most industrialized countries had restrictions on particulate release. Particulates cannot be the cause of global warming, but reducing their sources can cause the temperature to rise as can be seen in the temperature record after 1980.

The Greenhouse Effect was discovered in the early 1800′s when scientists realized that the Earth was kept warm at night because the atmosphere trapped invisible heat rays rising from the surface. Around 1860, John Tyndall identified the invisible rays as infrared radiation and found the main gases that trapped the heat rays to be water vapor and CO2. The amount of water in the air remains relatively constant because of the water cycle. When the humidity is low, water evaporates, and when the humidity gets too high, it rains. However, CO2 has no such restrictions. Since CO2 makes up only a few hundredths of a percent of the air, it was at first dismissed as a possible cause of warming as it was thought that plants and the oceans would absorb any excess. In 1896, Svante Arrhenius, while pursuing the idea that variations in CO2 might be the cause of the ice ages, laboriously calculated the effect of cutting the amount of CO2 in the atmosphere by half. He found that doing so would lower the temperature of Europe by 4-5 C, perhaps enough to bring on an ice age. He also found that doubling the amount of CO2 might raise the temperature of the atmosphere by 6-7 C. No one was concerned as Arrhenius’ model of the atmosphere was very crude and it was inconceivable that the amount of CO2 would ever double. Some scientists speculated that man should intentionally add more CO2 to the air to ward off another ice age.

As models of the atmosphere improved, a number of scientists tried to get a better estimate of the effect of doubling the amount of CO2 on the Earth’s temperature, but the increasing complexity of the models made the calculations daunting. A breakthrough came with the development of computers. In 1956, G.N. Plass calculated that doubling the concentration of CO2 in the air would cause a 3 to 4 C increase in the Earth’s temperature. Many dismissed his work, as it seemed impossible that CO2, which made up only 0.03% of the air, could have such a large effect on temperature. However, in 1997, J.T. Keihl found that, under clear sky conditions, CO2 accounted for 26% of the greenhouse effect – with water and other greenhouse gases accounting for the rest. Clearly, CO2 could have a significant effect on the Earth’s temperature if it was increasing. But was it?

CO2: In 1900, Arvid Hgbom calculated the amount of CO2 emitted by industrial sources and, surprisingly, found that man was adding CO2 to the atmosphere at roughly the same rate as volcanoes. No one thought much of it as, at that rate, it would take centuries for the amount of CO2 to increase significantly. However, after a protracted heat wave during the 1930′s, Guy Callendar re-examined previous temperature and CO2 measurements, and found not only that the Earth was getting warmer, but that atmospheric CO2 concentrations were increasing rapidly. Callendar’s work was mostly ignored, but a few scientists began monitoring the concentration of CO2 more closely. Their results were sporadic but, by 1958, Charles Keeling had established accurate procedures for measuring atmospheric CO2. His lab was eventually moved to the Mauna Loa observatory, away from CO2 sources. His graph showing how CO2 varies with time, now called the Keeling curve, proved to be an important piece of evidence. It showed that the oceans and plants were not taking up CO2 nearly as fast as man was producing it. Over the last century, the atmospheric CO2 concentration has risen from 280 parts per million (ppm) to 385 ppm, a 38% increase, and the Earth’s temperature has risen by 0.8 C, well in line with Plass’ prediction. The role of CO2 as the major cause of global warming had been convincingly established. There is yet one more piece of evidence that confirms that conclusion.

Ice Ages: It was now possible to solve the mystery of the ice ages. The Milankovitch cycles alone cannot explain the changes in the Earth’s temperature, but the process becomes clear if CO2 is included. The ice core data shows that the concentration of CO2 falls to about 200 ppm during an ice age and rises to about 300 ppm during the warm part of the cycle. The changing CO2 concentration happens because the solubility of CO2 in water varies with temperature. In the part of the cycle where the Earth is warmed by the increasing solar radiation, the oceans release CO2, which further amplifies the warming by the greenhouse effect. In the part of the cycle where the solar energy decreases, the oceans cool, the CO2 dissolves again, and another ice age begins. The concentration of CO2 in the atmosphere is the “control knob” for the Earth’s temperature – and we have now turned the knob up to 380 ppm and are moving it higher. The Earth will surely get warmer.

There is no denial to the fact that the climate of earth all across is changing every day. This is the consequence of continuous warming up of earth and atmosphere around it. The main reason is excess of carbon dioxide and gases like methane and nitrous oxide in the atmosphere. These gases are called greenhouse gases and are the reason for rising green house effect on earth. These gases have the capability to trap the heat and not allow heat to go outside the earth’s atmosphere. Hence, they result in more warming.

Global Warming is increasing day by day because of lot of natural and manmade circumstances. With so much of pollution and deforestation all across the globe, It is rapidly increasing. With more and more release of carbon dioxide in the atmosphere around earth, the temperature is also rising. Is it alarming? Well, the answer is yes.

Let us face it that climate change can be life threatening if earth is not able to adjust to it. Due to deforestation, a lot of species of plants, birds and animals are becoming extinct. Due to water pollution, a lot of water species are vanishing. With so much of imbalance in natural activities around, it is impossible to avoid climate change. Plants and trees absorb carbon dioxide from the atmosphere; make the air pure for us to breathe. However, we are only cutting them down. We should also grow trees and plants to ensure that the damage done by cutting down the trees is taken care of.

Glaciers are melting due to It and its effect of climate change. With global warming glaciers, lot of places all across the world can get merged under water. We cannot deny the fact that with melting glaciers, the sea levels will also rise. Natural calamities are hints which are given to mankind to beware them of the worst. Are we ready to face this? Well, we are still wondering how to control Global Warming. Global climate change is a threat to all. Countries are trying to invent ways to control it so that we can be healthy and alive in future.

If statistics are to be believed, then the temperature across globe is on rise. 1990s is recorded as the decade for rise in temperature. It is recorded as the warmest decade in almost thousand years. With raise in temperature degrees, extinct animals, plants and trees, melting glaciers, heat waves, it is becoming more and more important to start the fight with aggression against Global Warming.

It is the increase in the temperature of earth and its surface all across. The main contributor of carbon dioxide in atmosphere is power plants. These power plants burn fossil fuels and coal to generate power. Burning coal is the main contributor of carbon dioxide. With rise in carbon dioxide in the atmosphere the gas absorbs more and more heat around and thus increases the global warming.

The major threat from global warming is global climate change. Climate change can be life threatening also if people living in that area are not able to cope up with it. Glaciers around the globe are melting. Melting glaciers actually means rise in the sea level. If we think about it, then the rise in sea level in itself can pose a lot of threats to human kind. First and foremost, it can be a dangerous thing for all the tows and places near coastal areas. The life of people at such places can be in danger. Secondly, with rise in sea water level, there is threat to the ground level. When mixed with ground water, sea water can be a threat to the drinking water. Scarcity of drinking water in itself can result in lot of chaos.

With change in climate around the world, there will be more of natural calamities. Natural calamities like floods, droughts, cyclones, volcanoes etc. World will suffer a lot if global warming is not fought against today itself. We can also decrease the effect of its by controlling it. It can be done by a lot of things which we as individuals can start at home. Things like planting more and more trees around. Planting more trees will not just help in avoiding soil erosion. It will also help in releasing live saving gas i.e. oxygen. Apart from this, trees also help us in controlling the greenhouse effect by absorbing greenhouse gases.

However, if we look around we hardly find people planting trees. We can easily find people who want to cut trees and use them or use that land. We should also avoid using paper and go for electronic media. This will save trees as well.

Usage of plastic bags results in garbage and when this garbage is burnt, it releases more harmful gases in the atmosphere.

It is important to use these energy sources prudently, as they can be used to power just about anything in our lives. The renewable technologies for alternative energy today are able to meet all of our electricity demands. We all use and rely on a lot of electricity on a daily basis as a means of powering all of the gadgets that we use every day.

Green houses like carbon dioxide, methane, chlorofluorocarbons and carbon monoxide trap the infra red radiations from the sun and ensure that the earth is hospitable to various living species.

In fact, without these gases, the earth would be freezing and would not be able to house so many living species in the planet. The trapping of the sun’s heat by these greenhouse gases is called the ‘greenhouse effect’.

Since the amount of these gases has increased in the atmosphere, the amount of heat trapped is higher than normal and this has brought about an increase in the temperature across the globe.

Other factors that contribute to global warming include automobile emissions, industrial pollutants in the air and some of the agricultural and mining activities that emit greenhouse gases as by-products.

Using recycled products, unplugging electrical appliances when not in use, using energy saving gadgets as well as reforestation can go a long way in bringing the greenhouse gases back to normal concentration levels thereby making our planet more hospitable to the constant evolution of life.

Limiting the usage of appliances or compounds which produces CFC can also help. CFC is the major reason for the depletion of the ozone layer causing global warming. Another reason for global warming is the emissions from cars. The world has seen a geometrical increase in population. This has lead to increase in the number of cars. Identifying fuel efficient cars, use of bio-fuels, correcting the engine designs or even using electric cars are great ways to reduce emissions. Preferring walking, cycling and transportation by bus, train can also help to prevent global warming. Organizing carpools can also be a good method that can be done to reduce emissions.

In home people can try to conserve energy and electricity thus helping to prevent global warming. Switching to CFL bulbs which uses less energy and a longer life time can reduce the electricity usage. Reducing the usage of heaters and coolers can also help. Switching of electronics and other appliances which are not in use, replacing old appliance with less energy consuming goods can also help to prevent global warming. Alternative power sources like solar energy generators for homes is a good way to make sure that you are getting your power from means that are good for your earth.

Global warming is also caused due to less knowledge about it. Therefore awareness should be provided mainly to children and those in the factories so that they can also think about ways to conserve energy and to prevent the global warming. The future generation must be encouraged and taught to save the earth, our habitat. The media has a major role to play in making people understand the importance of global warming and its concerns. Only a collected effort by the entire humanity can reduce the global warming, which is a deep rooted problem. Global warming cannot be removed suddenly but many of the measures mentioned above if followed by an individual can contribute to reducing and preventing the global warming. Together we can make things happen and it is up to each of us to ensure that we take all steps to reduce global warming for us and for our future generation.

The main theme behind the prevention of global warming is to reduce the level of certain gases that enter our atmosphere and cause devastating changes to our world. It is certainly not possible for one person to reduce the issue of it, but change can start with one person. It is vital to our future, and the future of many generations to come, that we start putting this change into motion as soon as possible. If we all start contributing to the prevention of global warming, the results can end up positive for the entire world.

If you reduce the amount of some gases that you use, such as gasoline and oil, you are on the road to global warming prevention. The first step in preventing this is to try to reduce the amount of energy that you consume in your homes and businesses. It is important to understand that it takes certain oils to create the electricity that you use. If you use less electricity, then you will do less damage to the atmosphere. There are many ways that you can reduce the amount of energy that you use. First you can use lighting in your home that saves energy. As a matter of fact, it is better to make sure that all the items in our home are purchased under the fact that they are energy efficient.

Next step, Watch how much fuel that you use in vehicles and other fuel powered machines. You can use less fuel by ensuring that your vehicle is maintained, you drive less, and buy vehicles that are advertised to use less fuel. All of these tips will help you to save money on fuel, and will help to preserve our environment.

What you are able to reduce the effect that global warming has on your atmosphere. Practice the tips listed in this article, and pass them along as well.

For humans, these changes in climate are particularly dangerous to those who live near the ocean shore and who already suffer from drought, flooding, and poverty.

The IPCC concludes from models that global temperatures will likely rise by 1.1 to 6.4 C (2.0 to 11.5 F) degrees between 1990 and 2100, with the range of temperatures due to the use of differing scenarios of future greenhouse gas emissions and varying degrees of climate sensitivity.

Other effects of global warming include a rising sea level and changes in the amount and pattern of precipitation. In addition, there may be more frequent and intense weather events, such as more intense hurricanes, tornados, tsunamis, thunderstorms, blizzards, etc., though it is difficult to connect specific events to global warming.

Global warming is also causing changes in agricultural yields, glacier retreat, reduced summer stream flows, species extinctions, and increases in the ranges of disease vectors. The increased volumes of carbon dioxide and other greenhouse gases released by the burning of fossil fuels, land clearing, agriculture, and other human activities are the major reasons why global warming has been occurring and increasing over the last 50 years.

Effects of global warming are expected to cause more changes as it becomes more pronounced; examples include the following projected climate changes (from Wikipedia):

- “A significant slowing of the ocean circulation that transports warm water to the North Atlantic; – Large reductions in the Greenland and West Antarctic Ice Sheets; – Accelerated global warming due to carbon cycle feedbacks in the terrestrial biosphere, and – Releases of terrestrial carbon from permafrost regions and methane from hydrates in coastal sediments.”

It is uncertain whether for sure these events will occur or to what severity they will occur if they do, but most believe that the chances of at least one of the above events occurring are likely to increase the longer and more severe climate change becomes.

Some scientific members argue whether there will be positive effects from global warming, but most agree that any positive effects will be greatly outnumbered by the number of negative effects.

Projected climate changes due to global warming have the potential to greatly and irreversibly change our climate that will have lasting impacts on both the continental and global scales. One effect will be increased precipitation, due to the increasing temperature.

As Earth’s temperature continues to rise, a very recent report from the IPCC shows that there will be an increasing impact to natural systems and people, especially those who live in Earth’s poorer nations. In 2002, Colorado, Arizona, and Oregon endured their worst wildfire season ever. Also in 2002, drought created severe dust storms that caused hundreds of millions of dollars of damage in Texas, Montana, and North Dakota. Since the early 1950s, snow accumulation has decreased by 60%, which has led to some areas of the Cascade Range in Oregon and Washington to have shorter winter seasons.

As you can see, effects of global warming are very negative on our planet already, from increased air temperatures to rises in the sea level to more severe storms. Currently, it is a challenge to predict how many effects global warming will have and how strong those effects will be, but most of the scientific community is predicting that global warming will have more negative effects on our planet and way of life the longer and more severe climate change becomes.

While some countries in Europe have taken steps to curb the menace arising out of the environmental crisis, other countries have lagged behind in the effort to tackle the problem. Most notably, France has taken the lead in addressing the issue with tighter environmental standards for vehicles and expecting greater fuel efficiency from the new vehicles that are being manufactured.

It is noteworthy that the Euro standards for emission have been proposed first in the European countries that form part of the European Union. The EU has been at the forefront of the global efforts to tackle climate change. While the rest of the industrialized world has been found wanting in the efforts to halt the problems caused by global warming, countries like France and Netherlands have taken steps to reduce the carbon footprint.

Forests are the key to maintaining the precarious balance in the environment and hence countries should take steps to avoid deforestation. This can be done if paper is recycled since most of the paper comes from wood that is available after cutting down the forests. Further, use of CFC’s or Chloro Flouro Carbons that are emitted by the home appliances like refrigerators and using Aerosols should be avoided or if that is not possible, limited.

There is an urgent need to reduce dependence on fossil fuels as well as the emissions from vehicles using petrol and diesel are one of the primary drivers for climate change. As noted above, the EU has been proactive in making tighter emission standards mandatory for vehicle makers. Further, in many of these countries, most of the power generation is by nuclear plants and Wind mills making the process of power generation clean and green.

It is high time that the developed world took steps to mitigate the effects of global warming and act decisively on the issue. Without getting into debates on who caused the problem of global warming, the leaders of the countries must focus on what needs to be done. The window for taking decisions and staving off the effects of climate change is closing and hence it is expected that Europe would show the way forward in tackling this issue. Much has been done till now, but, more is expected.

The climate change summit in Copenhagen must be used as an opportunity to ratify the Kyoto protocol on environmental standards that lays a time bound program to address climate change.
