Climate Change

The U.S., China and many other nations say they hate it, but the European Union is determined to lead the way to a greener aviation industry. In 2012, all flights to or from an EU airport will be subject to a new greenhouse gas emissions tax.

This new tax is expected to boost each EU passenger fare from $3-$15. Revenues raised by the new tax, it’s been calculated, could add up to $26 billion over the rest of the decade. The funds will be invested in efforts to slow global warming, and should spur greener technologies in the aviation industry, which is responsible for roughly 3 percent of all global carbon dioxide emissions.

Europe decided to create its own aviation carbon taxation system only after the rest of the world failed to act. Negotiations overseen by a United Nations agency aimed at creating an international carbon cap-and-trade pact have dragged on for 10 years.

Global airlines have lodged many objections to the EU’s initiative, but none is stronger than its stipulation that a Europe-bound flight gets taxed from start to finish, not just when flying over Europe. Cries of outrage invoke national sovereignty and conflicting international aviation agreements. Some countries may try not paying the tax or may make further court appeals, according to the New York Times. Sabre-rattling has even extended to hints of a trade war directed at the EU.

Significantly, some airlines support the new tax. One is Virgin Atlantic, which issued this statement: “Virgin Atlantic has long been a supporter of the EU Emissions Trading Scheme as the first step towards a future global solution ensuring aviation plays its part in meeting climate change targets. However, its success is being seriously undermined.”

What will really happen when the tax goes into effect will soon be known. But this much is clear: Europe intends to stand firm, believing that action to reduce global warming is too important to delay. When the rest of the world decides to act, they say, they’ll happily make changes to their cap-and-trade system to help create a true multinational process for reducing dangerous aviation emissions.

The electricity generation process involves a considerable number of energy changes, without regard for the primary power source that is used. Historically, electricity has been generated using fossil fuels, particularly coal. More lately, power stations have begun to use oil and gas as their energy source. Oil-fired power stations are not unusual in oil making countries, eg Indonesia. Gas burns more cleanly and efficiently than coal. It releases half as much carbon dioxide and more than 1000 times less sulphur dioxide per unit of energy.

Burning fossil fuels in power stations

The heat released from burning fossil fuels is used to boil water to produce steam. The steam is heated to really high temperatures in order that it is at high pressure and can turn gigantic steam turbines. Some of the energy of the steam is changed into movement, or kinetic energy, as the turbines spin. The turbines are hooked up to the coils of giant generators. The coils carry a current and act as electromagnets. As the turbines spin, they produce an electric current in the fixed coils surrounding them. This is fed into a power supply grid and carried to wherever in the network it is needed.

Power stations can’t store surplus electricity, so electricity generation has to match demand. The power firms have to judge how much power will be required. During periods of hot weather, electricity demand may increase as more folks use air conditioning to keep their houses and offices cool. If power corporations’ estimates are wrong, people may experience power cuts.

Power stations aren’t really efficient, and between 50 and 70 % of the energy contained in the ordinary fuel is wasted. Some of the heat energy will heat the encircling air and escape thru the boiler chimneys. The heat energy locked away in the steam cannot all be moved to the spinning turbines. Though the steam is cooler when it leaves matched against when it enters the turbines, it’s still warm. The steam is carried to the cooling towers, where it cools sufficiently to compact back to water. The warm water is then emptied Into a nearby stream or sea, where it can cause thermal (heat) pollution. Hot water holds less oxygen than cold water. The addition of a large amount of luke-warm water can cause animals, such as fish, to ‘suffocate’, as they are unable to extract enough oxygen from the water.

Combined heat and energy generating plants

Some power stations, called mixed heat and power generation plants (CHP), try to make use of the waste heat. They pipe the waste hot water to surrounding businesses and houses to provide heating. There are numerous such units in Germany, and many tiny towns are reaping rewards from this cheap energy source. However , this is only possible with tiny and medium-sized energy generation stations that are built close to cities. In many states, especially the United Kingdom, power stations are found in more remote locations and so this power source wouldn’t be as practical as even solar power.

Electricity is mostly generated at an amount that meets what is demanded, as it is tricky to store surplus energy. Nevertheless it’s feasible to store smaller quantities of energy for personal and domestic uses. Batteries and fuel cells both produce electricity by employing electrochemical reactions. Flywheels store energy as they spin.

The battery

A convenient store of energy is the electric cell or battery. These are used each day to power torches, radios, toys and lots of other gizmos. The most common form of battery contains carbon and zinc separated by a solution of ammonium chloride. When the battery is attached to an electric circuit, its stored chemical power is changed into electric energy. The battery continues to supply an electrical current until all the chemicals have reacted with one another. Then, the battery is said to be ‘flat’. Batteries comprising nickel and cadmium (Nicads) can be recharged by passing a tiny electrical current thru the battery for one or two hours. This makes them last much longer.

Flywheels

Space stations use solar generating panels and fuel cells as their energy source. This energy is then stored in batteries. These batteries are large and expensive and need to be replaced each 5 years. But new space stations and satellites may use flywheels to store the energy. These can last as long as 20 years. Flywheels are employed in engines, but now scientists are designing far more efficient versions. When energy is used to spin a flywheel, the energy is converted to kinetic energy. The flywheel stores the energy mechanically in the form of kinetic energy. The quicker the flywheel spins, the more energy it stores. This energy can be converted to electricity. The new flywheels will be as small as just fifteen centimetres across, and made of highly strong, yet lightweight, materials. They will spin up to 600,000 times each minute, and can store 8 times more energy than a battery of the same mass.

Fuel Cells

It’s feasible that in the near future, car engines, batteries in laptops and even power stations might be replaced by fuel cells. Fuel cells date back to 1839, but until recently, only the US State Aeronautics and Space Administration (NASA) made use of them.

All fuel cells are energy converters, and work on identical elementary principle. They have two electrodes separated by an electrolyte, a substance that conducts electricity. A fuel like hydrogen enters at one electrode and oxygen enters at the other. They undergo a reaction, which produces an electrical current. When the fuel is hydrogen, the only waste product is pure water.

Fuel cells have many advantages. They convert energy much more efficiently than typical power sources: as an example, a fuel cell is two times as efficient as a vehicle gas engine and produces virtually no pollution. Additionally, they do not contain moving parts, so don’t produce any noise or vibration. An operating fuel cell is so very quiet and does not have wear and tear. However , there are a considerable number of issues to beat. Now, fuel cells are extremely costly, although this is thanks to the fact that only small numbers are being made. The price will fall once large quantities are produced. There are also issues of trustworthiness with some fuel cells. Additionally, some larger fuel cells have a poor power to weight and volume ratio. This suggests that for their weight or volume, they produce relatively small quantities of power.

Smog

The particles and gases from car exhaust pipes can create photochemical smog. This sort of smog is particularly common in hot, dry and bright cities like Athens in Greece, Cairo in Egypt and Mexico City. The vehicle exhaust pipes pump out gases like nitrous oxide, carbon monoxide and ozone that react together in the sunlight. The result is a smoggy haze over the city.

LA in California, USA, has suffered badly during the past from smog. The smog was due partly to the exhaust fumes from millions of cars, but also from the local geography. The town lies by the coast and is encircled by mountains. In certain climatic conditions, the smoggy air would be encircled over the city, and air quality would fall steadily until atmospheric conditions changed and the smoggy air was replaced by cleaner air. A hazy layer can still be seen over Los Angeles, but the level of pollutants has fallen dramatically due to new legislation and improved pollution control on vehicles.

Acid rain

Coal-fired power stations release sulphur dioxide, especially those burning lignite coal. This gas, along with nitrous oxides from vehicle exhausts, reacts with water in the air to form weak acids. These acids create acid rain rain that’s got a lower pH than standard. Acid rain erodes and damages the outside of buildings and statues, particularly than made from limestone.

Acid rain falling on conifer forests in mountainous areas of Scandinavia, North America and central Europe has been the cause of longterm damages to the trees. The soils become more acid and this leads to damaging compounds,eg aluminium, to be released. The first indications of damage are a tree’s needles becoming brown and full branches dying. Increased astringency in the soil damages trees ‘ roots, and this decreases their power to take up water and nutrients. The trees become more vulnerable to frost and illness. Eventually, they die.

Lakes are also exposed. The acidic rainwater drains off soils into the lake, leading it to become more acid. Aluminum in the water causes the gills of fish to provide more mucus, and this prevents them from getting sufficient oxygen from the water. In extraordinary cases, all life in the water may die.

Global warming

Burning fossil fuels releases carbon dioxide. Carbon dioxide is called a ‘greenhouse ‘ gas, as it traps heat in the atmosphere. The presence of some greenhouse gases keeps the Earth at a temperature of roughly 15C, which allows life to survive. A increase in the use of fossil fuels has caused the levels of carbon dioxide in the atmosphere to increase, too. More carbon dioxide implies more heat is trapped, and this has caused the average worldwide temperature to rise. This is called global warming.

The exposed solar power effects of global warming are uncertain, but it’s probable that the skyrocketing temperatures will disrupt climates around the globe, causing some regions to have lower rainfall and other regions to have more. The hotter temperatures will cause ice caps and glaciers to melt, which, mixed with the growth of water in oceans, will cause sea levels to rise, flooding low lying areas which are heavily populated. Acute weather events such as droughts and storms could also become more common.

Considering the fact that the holes in the Earth’s ozone layer are focused around the poles, not even close to where the majority of people are living, it would appear that the ozone layer depletion is a concern that does not demand an immediate resolution. The truth is, the deterioration of the Earth’s defense against radiation has ramifications that extend across the Earth. The ozone layer’s depletion leads to numerous environment problems that in the end affect each and every inhabitant on the planet.

The sun produces uv radiation that must be filtered. Particularly, it is the UVB rays that the ozone layer helps to keep from getting into our atmosphere. Radiation, in small amounts, is essential. In large amounts, though, it could harm the planet. An excessive amount of radiation may cause permanent harm to the DNA of living creatures. This means it may cause cancers in both people and wildlife.

There are numerous effects of global warming due to the ozone layer depletion. To illustrate, the costs of food and the availability of drinkable water are impacted. As stated by the Intergovernmental Panel on Climate Change or IPCC, the number of regions worldwide being affected by droughts has been progressively rising since the ’70s.

Not only does the increasing amount of ultraviolet light that penetrates the Earth affect animals, it also affects plant life. Some plants may behave differently because their life cycle and ability to create ripe fruit is affected by the presence of ultraviolet light. The survival rate of microscopic plant life in the oceans, however, may drastically go down as a result of increased exposure to ultraviolet light.

Other effects of climate change manifest themselves in more immediate and dramatic ways. For instance, according to the IPCC, the tropical cyclone activity in the North Atlantic is now more intense compared to the tropical cyclone activity in the 1970s. The storms today are more intense than the ones several decades ago. As a result, many houses and buildings built to weather storms common in the past are buckling under the storms today. Many of these structures are unable to hold up, resulting in huge damages and even fatality.

The storms are terribly difficult to predict, thereby making it also difficult to ascertain if expensive upgrades designed to enable buildings to withstand the storms are worth doing. Without a doubt, the ozone layer depletion causes environmental issues that are varied and potentially life threatening. Unless a serious, focused action is taken, the problems caused by the depletion of the ozone layer will only worsen and will be felt by every person on the planet.

Everyone plays a role in global warming with the production of gases. Similarly, everyone is impacted by global warming. It is essential that every one of us make a move to help our world. We can implement modifications in our way of life that immediately help the environment, as well as lobby our governments to act.

The sooner we take action, the sooner we will be able to control the ozone layer depletion, along with the harm it causes to the ecosystem. We also can take the proper steps for the effects of global warming that can not be avoided any longer.

Russ Evans is concerned with the environmental issues connected with ozone layer depletion in addition to global warming information which he believes are of interest to absolutely everyone

According to experts, even though global warming is an urgent problem, every American can take concrete steps in order to be part of the solution. Every day, there are so many things we do that use energy which is why we have a lot of opportunities every day to make a difference.

Here’s the Problem

Global warming pollution is released when cars, factories and power plants burn fossil fuels, such as oil and gas. For many decades, these pollutants accumulate in the atmosphere and they act like a huge blanket that traps heat. That, in turn, warms our planet. Still in the atmosphere is the global-warming pollution, primarily carbon dioxide which is emitted from the first model T’s and it acts like a thickening layer of insulation. With our increased reliance on fossil fuels, the concentration of these pollutants continues to accumulate, threatening the stability of our climate.

Across the nation, distinguished scientists are surprised by how fast and severe these issues are and how it affects people’s lives such as the elderly suffering from heat waves, families whose homes are threatened by floods and eroding coastlines, hunters and anglers watching wildlife disappear and homeowners who are at risk of mudslides.

Scientists are convinced that the most dangerous consequences can be avoided because we now have a small window of time. They say that if we join together now to solve this problem, then our children may be spared even more dramatic effects within their lifetimes.

What are the Solutions?

There is a website that list easy ways that can be helpful when slowing down global warming. For example, were you aware that

By taking simple steps as selecting Energy Star appliances and insulating their house, an energy-conscious family can then reduce its global-warming pollution contribution by over 35,000 pounds per year.

If you want to save money on electricity, then what you can do is install a programmable thermostat which can reduce global-warming solution.

If you plan your trips to combine errands, this will reduce emissions, saving gas, wear and tear on your car, and your valuable time.

Choosing the most fuel-efficient model in its class is the single most important way to cut global-warming pollution regardless of the kind of vehicle that you drive.

Dedicated to protecting the environmental rights of all people, including the right to clean air, clean water, healthy food and flourishing ecosystems is a centrist organization called Environmental Defense. Environmental Defense is guided by science and it works to create practical solutions that win lasting economic and social support because they are nonpartisan, cost-effective and fair.

The Kyoto Protocol was the 1st try to get a handle on the global warming problem. It was created by a branch of the UN called the U. N Framework Convention on Climate Change. I know, it is a mouthful so we’ll call it the UNFCCC. The protocol was initially brought into being and adopted on December 11, 1997 but wasn’t brought into force until 2005. The reason that it took so long for it to do something was due it needing 55 parties to confirm the protocol. Russia was the last one to do it and make it all official.

The idea was to reduce Carbon emissions in the atmosphere to levels that would reduce the probabilities of sending our climate change to levels that would make our lives on this planet unsustainable. This is a very important thing to do but there are still nations that have not ratified the deal and agreed to its directives. Most of the planet has ratified the protocol, 187 to be accurate, however the U. S. only symbolically signed it, but that’s non-binding without ratification.

The most important factor to the US not adopting to protocol was that it didn’t have much of an impact on developing nations. The protocol was targeted at 37 industrialized countries since the industrialized nations that are making the majority of the CO2 emissions that are threatening our planet. Another factor to the US not ratifying the protocol is that it was felt that it may do damage to the US economy.

When developing the Kyoto Protocol to combat planetary warming, the 37 nations that we targeted are legally required to reduce their greenhouse gas emissions by 5.2% from the 1990 levels. It was determined that 1990 would be the baseline for the accord. There are timelines to try and reach this goal before 2010. Even though they are reducing the Carbon emissions by only 5.2% this would actually turn into a 29% reduction since the levels had increased so much since 1990.

The Kyoto Custom targets six different CO2 emissions including carbon-dioxide, methane, sulfur, nitrous oxide and HFC’s. These are the primary gases that are causing the problem by collection at the very top of our atmosphere and not permitting as much heat to flee into space as was previously getting out.

They figured in many ways for the participating countries that aren’t able to quite meet their shares to still be in a position to be in compliance. If the country in question is unable to get below the levels that were prescribed by the Kyoto Protocol, they’ll be in a position to purchase “credits” from other nations that are exceeding their predicted reductions.

The Kyoto Protocol’s efforts toward fighting global warming is a great initial step. There’s still more that must be done however. If some of the leaders of the world can come together and begin to implement these changes, then why not have a look at some specific things you can do to help out too.

As you are buying retreads from Tread Wright, you can have the satisfaction of knowing you are undoubtedly going green and saving nearly 70 percent of the petroleum and raw materials used to manufacture a brand new tyre. Also, you can additionally save over 50 percent over the expense of a equivalent brand new tyre. TreadWrightTread Wright. offers various dimensions of retread tires tires, like the the 37×12.5R16.5.

To be able to know how perilous global warming could be to the planet, we must first understand just how intricately our environment works. Our ecosystem on this planet is an especially exact operation, for example, fish feed at the coral reefs in the seas and if those reefs start to vanish (as they are) then that may affect the fish that feed there, probably causing complete species to die out.

You see everything is reliant on everything else in our surroundings. Birds and other wildlife live in the trees that are being so speedily cut down. Once that occurs, the birds have to go somewhere else, where there’s likely other wildlife already there and that puts a heavier burden on those animals. There’s a cause and effect to everything that goes on.

Global warming has become a big threat to the wildlife of this planet and scientists claim that global warming is the one biggest threats to the wildlife here on earth. If we do not start to take the relevant steps to ease this phenomenon, then we risk putting even more of these fragile ecosystems out of commission.

There has been a great deal of damage done to the ecosystems here on Earth that are only going to become worse if we don’t start acting on them now. Penguins for example are starting to suffer seriously thanks to the loss of ice in the arctic regions. The ice disappears and this has the effect of lessening the quantity of algae in the water. The salt water shrimp which make up the bulk of the penguins diet therefore can’t survive since they eat the algae. Without the salt water shrimp, then penguins can’t survive in the area either.

Polar bears and seals are also fighting to adjust to changing climate in the arctic. Seals move from ice trail to ice trail and mate, have their young and feed there. Polar bears are much the same, and the vanishing ice there’s leaving them with fewer and less places to be able to carry out their life functions.

Surely you are beginning to see the pattern here and realizing that when one thing is influenced in the world, other things get affected also. Certainly you can see how eventually this is going to get to us humans as well.

As an example as the world population increases, we humans are putting out more CO2 every year than formerly. If you remember from early science classes you can make the link that trees absorb the carbon dioxide that we put out and produce oxygen.

While there are rather more of us on the planet each year (and this trend doesn’t seem to be reversing) and less and less trees every year, does it not stand to reason from a common sense point of view that eventually we are going to reach a tipping point where the trees are not able to keep up with us. These aren’t tough arguments to make or to follow, but some just don’t want us to be forced to change our ways of living here on our home.

As you are buying retreads from Tread Wright, you will have the satisfaction of knowing you are indeed going green and saving as much as 70 percent of the petroleum and resources necessary to assemble a brand new tyre. Plus, you can additionally save around 50 percent over the expense of a equivalent brand new tyre.

Outside of the topic of abortions, global warming is a good subject to bring up when you want to get into a heated debate. Fists will soon be flying as people stake out their positions. Here is a great example of how hot things can get, no pun intended.

Global warming – at least the modern nightmare vision – is a myth.

I am sure of it and so are a growing number of scientists. But what is really worrying is that the world’s politicians and policy makers are not. – Professor David Bellamy

Information Administration projects that both U.S. coal use and carbon dioxide emissions are currently slated to increase by 40 percent by 2030. – Gus Speth, Yale School of Forestry and Environmental Studies.

The problem we are faced with is that the meteorological establishment and the global warming lobby research bodies which receive large funding are now apparently so corrupted by the largesse they receive that the scientists in them have sold their integrity. – Piers Corbyn

The only people who would be hurt by abandoning the Kyoto Protocol would be several thousand people who make a living attending conferences on global warming – Professor Kirill Kondratyev, Russian Academy of Sciences

In fact, even the current administration now is releasing recent reports indicating that climate change is real, that global warming is occurring, that it is heavily influenced by man-made objects and that it is something we cannot ignore any longer. – Ron Kind

Global warming is not a conqueror to kneel before – but a challenge to rise to. A challenge we must rise to. – Joe Lieberman

While human-induced global warming is not going to turn present-day Earth into present-day Mars, global warming is dire enough that our most distinguished scientists recently concluded that as many as 1 million species on the planet could be extinct by 2050 if affairs do not change. – Jay Inslee

It used to be controversial whether smoking caused lung cancer, it used to be controversial whether HIV caused AIDS.

Now, there are a few mavericks who deny those things. In the case of climate change, I think the debate is going the same way in that there is a strong consensus that it is a serious matter. – Lord Martin Rees

In comparison to 10 years ago, now all countries recognize that climate change is an important issue, that we must continue Kyoto, that the time after 2012 must be in our sights and that we must do everything possible to improve energy efficiency and, at the same time, facilitate economic growth. – German chancellor Angela Merkel

The absolutely best case scenario – which in my opinion is unrealistic – with the minimum expected climate change… we end up with an estimate of 9% [of all species] facing extinction. – Chris Thomas, University of Leeds

those who are absolutely certain that the rise in temperatures is due solely to carbon dioxide have no scientific justification. It’s pure guesswork. – Henrik Svensmark

When the penny drops to President Bush that global warming is really serious, they’re going to be in trouble. – James Lovelock

With all of that being said there is a fact that we can all agree on. The sun, has immense power that rains down on virtually the entire planet daily. There is far more energy than heat energy. We can capture the energy of the sun to transform it directly into electric energy stored in batteries. Other scientist recommend we transform it into hydrogen by the process of electrolysis. Then the hydrogen can be used as fuel much in the same way as we currently use gasoline. Regardless of which direction you feel is better, the movement is clearly shifting to prefer the electric path. Lithium ion batteries are becoming far more affordable than ever before and they are holding more charge than in the past. Electric cars are making their way into the common place in peoples lives across the globe. So it is a good idea to look into purchasing a few solar panels to not only power your home or electric vehicle but also sell back the electricity to your power plant to earn a profit! Earning extra money is on every one’s to do list.

Before you buy anything online, make sure the solar system has the PV panels that fit your budget and Before you buy anything online, make sure the solar system is right for you.

Imagine the next time you join a discussion about global warming causes. When you start sharing the fascinating global warming facts below, your friends will be absolutely amazed.

Scientists, together with us environmentalists, are constantly warning politicians that time is running up but that doesn’t seem to bother them, especially now in times of recession. Revive economy or save the planet? Scientists and economists can agree with Buddhist monks and Christian activists that ruthless destruction of natural habitats is evil and careful preservation of birds and butterflies is good. The worldwide community of environmentalists-most of whom are not scientists-holds the moral high ground, and is guiding human societies toward a hopeful future. Scientists are human; they do not wait for proof. Many devote their professional lives to seeking evidence for hypotheses, especially well-funded hypotheses, they’ve chosen to believe.

Complex economic tools including computable general equilibrium models, international input-output models and engineering-economic models are used to assess the baseline emission levels and abatement costs for the economies examined. All outcomes suggest that abatement is possible, but will be expensive. Consider the distant past. Two hundred million years ago the earth was much warmer than it is now: dinosaurs roamed the Antarctic, which was then lush and tropical. Could it really be the case that the ‘global warming crisis’ is really as much about careers and power as anything else?

Sometimes the most important aspects of a subject are not immediately obvious. Keep reading to get the complete picture on the causes of global warming.

Global warming could result in rising sea levels and flooding. There could be more powerful storms. Global warming has given birth to a new scramble for territory and resources among the five Arctic powers. Russia was the first to stake its claim in this great Arctic gold rush, in 2001. Global warming becomes a big issue in today’s media. If we read a newspaper or watching news on TV you may read or hear about global warming, what is global warming?

Environmental policies have particularly been difficult to implement because they have historically conflicted with economic goals and the performance evaluations of local officials were tied to GDP targets rather than environmental performance. This appears to be changing energy conservation, is now a pillar economic strategy and, from what I understand, has become a key metric in the promotion evaluations of local officials. Environmentalists claimed the number of scientists supporting the measure was “overwhelming”. That never was true.

Greenhouse gases trap heat energy trying to escape from the planet’s atmosphere. It normally goes out through virtual windows, which are becoming plugged. Greenhouse experiments show that many plants growing in an atmosphere enriched with carbon dioxide react by increasing their root-to-shoot ratio. This means that the plants put more of their growth into roots and less into stems and leaves.

I hope that reading the above information about real global warming issues was both enjoyable and educational for you. Your learning process should be ongoing–the more you understand about any subject, the more you will be able to share with others.
