Global Warming and Mechanism

Global warming is a recently evolved, insidious anthropogenic disaster. It is the documented historical warming of Earth’s near-surface temperature. Global warming came into existence in mid 20th century and has been progressing at an unprecedented rate ever since. Global warming is sometimes used synonymously with the term “climate change”. However a basic difference exists between the two. Climate change is identified state of change of climate which persists for a decade or longer, whereas Global warming is the combined effect of man made green house gases and change in solar irradiance. Global warming has emerged as a humongous problem facing the fast and ever growing world.
Speech about Causes of Global Warming and Mechanism

As mentioned earlier, it is a combined effect. Over the years of development of new and improved products for living, their has been an neglected, unwanted rise in gases that are causing gradual destruction of the protective blanket around our globe i.e. the Ozone layer. Global warming is an uncalled for event following employment of harmful greenhouse gases such as Carbon Dioxide (CO2), Nitrous Oxide (N2O), , Methane (CH4), and aerosols such as Chlorofluorocarbons (CFC), Hydrocarbons (CHC), etc.

These gases form O. free radicals which combine with Ozone and convert it to O2 and other non-protective gases. Thus solar energy which was impermeable to the Earth’s atmosphere due to the unyielding Ozone layer, is clear of all the obstacles.
Speech about Effects and Control of Global Warming

According to the World Meteorological Organization (WMO), the decade of the 2000s (2000–2009) is the warmest on record. The global mean surface temperature for 2009 is currently estimated at 0.44°C/0.79°F above the 1961-1990 annual average of 14.00°C/57.20°F. Global warming is a potential health hazard.

The deadly effects of global warming include

Polar Ice Caps melting will raise sea levels and throw global ecosystem out of balance.
Increased probability of draught and heat waves.
Increased incidence of hurricanes leading to disruption of ecology, loss of lives and damage to property.
High prevalence of cancers, especially skin cancers, in areas which have thin Ozone layer Eg: Australia
Economic consequences due to impending disasters.

Speech about Control of Global Warming

Every individual can participate in protection of our environment. The WHO slogan “Think globally. Act locally” is the biggest proof that all of us can help in saving our Mother Earth from the deleterious effects of Global warming. The cumulative efforts will make a huge difference to the present pathetic conditions. The measures we can take are:

Switch to energy efficient appliances

Turn off air conditioners when not in use
Have a solar water heater
Recycle often
Use eco-friendly products
Be a catalyst. Talk, encourage and participate in local movements
Plant more trees
Use renewable sources of energy

Why Waste Management is Essential

When you ensure that your garbage is properly disposed of, you contribute to less environmental pollution and help improve public health.

Importance of Waste Management

Here are five reasons why it is important to ensure that you dispose of your waste properly at all times:

  • Encourages recycling: Recycling plays a very great role in how the environment is impacted. When your garbage is recycled, you ensure that it gets used again productively to make new items and reduce the need for new raw materials sourced from the environment. This means that when you recycle your trash, you not only reduce trash but also allow waste materials to be reused.
  • Protects the environment: When proper waste collection in London is practiced, it plays a huge role in the protection of the environment. Hazardous materials are prevented from contaminating the environment.  These junks are properly separated and treated so that they do not have a negative impact on the planet.
  • Improves public health: As mentioned earlier, one of the benefits of proper trash management is that it helps in improving public health. When environmental pollution is reduced, it creates a greener and safer world for everyone. It also helps in reducing the risk of respiratory diseases and cleaner water ensures that harmful chemicals are not consumed.
  • Benefits the economy: Proper trash collection in London benefits the economy as well. Certain waste, like wood chips and yard trimmings, can be converted into an important part of a farm or garden through composting. This practice replenished the nutrients in soil and mitigates the need for soil reclamation services. Composting also keeps organic wastes from landfills and can even save money for communities as it does away with the need for landfill covers.
  • Reduces greenhouse gases: One of the major environmental issues today is climate change. With proper disposal of waste, greenhouse gases such as methane and carbon monoxide can be reduced so that global warming does not pose a threat to the planet. According to ecologists, if these gases are not reduced through proper waste management and other practices, the world could heat up to 7 degrees Fahrenheit by the year 2100.

As you can see, proper trash management is essential and both homes and businesses have a responsibility towards the earth to keep it green and clean. With proper waste collection in London, further damage to the environment can be prevented. Additionally, pollution, that is a major contributor to global warming, can be minimized and public safety can be ensured. Widespread disease caused by water pollution can also be eradicated when garbage is always properly disposed of.

Proper management of waste has a major effect on the environment and this is continuing to grow on a daily basis. From proper waste collection in London to recycling efforts, effective management of waste has become an integral part of everyone’s life and it is having a positive impact on the world we live in.

New Research Shows Greenhouse Gases Do Not Absorb Enough Heat to Cause Global Warming

Dr. Peter L Ward, a long time government geophysicist, has spent ten years carefully reexamining the physics of global warming, and discovered that greenhouse gases simply do not absorb enough heat to cause warming. The dirty secret in climate science is that greenhouse gases have never been shown experimentally to warm air as predicted by climate models, says Ward. Ward’s findings are so compelling he is offering a $10k prize to the first scientist to prove him wrong experimentally.

On April 22, Earth Day, many world leaders plan to sign the Paris Accord limiting greenhouse gas emissions. “What if we spend trillions of dollars and do not reduce global warming,” asks Dr. Peter L Ward, “We need to be sure the science is right.”

Dr. Ward observes the following:

Heat results from oscillations of the bonds that hold matter together. These oscillations cause matter, at different temperatures, to radiate thousands of frequencies shown by the shaded areas in the figure. Carbon dioxide, however, only absorbs frequencies shown by the vertical red bars, representing less than 10% of radiated heat. Plus, carbon dioxide molecules make up less than 0.04% of all molecules contained in air. Very few molecules each absorb very little heat.

What you feel as heat results from a broad spectrum of frequencies. An ordinary light bulb, with a filament glowing at 5500 degrees Fahrenheit, emits the broad spectrum shown in yellow, most of which is wasted because your eyes only see the effects of visible radiation. Radiation from a light bulb feels hot and it takes a lot of electricity to heat the filament. A fluorescent bulb or LED, on the other hand, radiates only a narrow range of visible frequencies, feels cool, and consumes much less electricity. Radiation absorbed by carbon dioxide contains little heat and does not feel hot.

Earth’s atmosphere is heated by high-energy solar ultraviolet radiation that causes molecules of certain gases to split apart, converting energy in the bonds directly to heat. Most ultraviolet-B radiation heats the ozone layer, 12 to 19 miles above Earth. When ozone is depleted, more ultraviolet-B reaches Earth, cooling the ozone layer, warming oceans efficiently and warming air by destroying ground-level ozone created primarily from pollution.

Ozone depletion caused by manufactured CFCs (chlorofluorocarbon gases) caused warming from 1970 to 1998. Warming was halted when the UN Montreal Protocol mandated cutbacks in CFC production.

More recent warming began in August 2014 when the 6-month eruption of Bárðarbunga volcano in central Iceland extruded 33 square miles of basaltic lava, the highest rate of lava production since 1783. Such exceptional lava flows have caused ozone depletion and major warming throughout the history of Earth.

“Global warming is happening,” Dr. Ward explains, “but greenhouse gases do not absorb enough energy to be the culprit. Ozone depletion, on the other hand, explains the details of warming clearly, directly, and completely throughout Earth history.”

Today, Ward is urging thousands of climate scientists to go to ClimatePlea.com and consider the evidence. Last November Ward offered a $10k prize to the first scientist who can prove experimentally that greenhouse gases cause more warming than ozone depletion. There have been no takers.

About Dr. Peter L. Ward:

Dr. Ward worked 27 years with the United States Geological Survey as research geophysicist, branch chief, and program manager. He helped develop and manage a major national research program, chaired a committee at the White House, testified before Congress, worked on a committee for Vice President Gore, published more than 50 scientific papers, and won two national awards for explaining science to the general public. He retired in 1998, working intensely for the past decade trying to resolve several enigmatic observations related to climate change.

Ward’s analysis and theory are explained in detail on his website and in his new book “What Really Causes Global Warming? Greenhouse Gases or Ozone Depletion?”

Economic Benefits Of Alternative Energy

Global warming is an alarming concern for the governments all across the world. The average global temperature across land and ocean for 2015 recorded a 1.62°F rise compared to the 20th century average of 57.0°F. Since the rising level of atmospheric CO2 is the primary cause of global warming, some of the world’s most carbon-intensive economies, including the US, face an enormous challenge. While there is little doubt that alternative energy technologies can help dramatically cut the nation’s consumption of traditional fossil fuels, there is a socio-economic reason for the US government to give a push to the renewable sector. Multiple researches reveal that investments in alternative energy projects can provide a boost to the country’s job market. The alternative energy sector in Tampa is a good case in point. The sun-kissed Florida city, which has experienced a steady growth in its solar sector over the past few years, reportedly generated thousands of jobs for those managing, installing and maintaining solar equipment throughout the supply chain. This job growth holds a ripple effect, which in turn benefit the local economy in many ways.

Employment Boost

As opposed to capital-intensive fossil fuel technologies, the renewable energy industry is more labor-intensive, and therefore, capable of generating more jobs. In 2009, the Union of Concerned Scientists (UCS), a US-based science advocacy non-profit organization, conducted a research to analyze the economic benefits of a 25 percent renewable energy standard by 2025. The report predicted that if implemented successfully, such a policy would create 202,000 new jobs in 2025.

Economic Ripple Effect

In any economy, when an industry experiences growth, other sectors also start gaining from its spilling effects. Take Tampa as an example, where growth in the solar photovoltaic industry benefitted unrelated local businesses.

More Income for Local Administrations

With new renewable energy plants coming up, local governments enjoy a fresh stream of income from new sets of taxes on properties and income of the alternative energy companies. The increased revenues help to support vital public services. Not only for the governments, they also open up new channels of supplementary cash-flow for the rural landowners and the farmers, as they keep on receiving handsome income in lease payments and royalties on a life-long basis. Taking 2025 as the target year, UCS analysis found that the national renewable electricity standard would garner $13.5 billion in new landowner income in the form of land lease payments coming from biomass and wind farms, and $11.5 billion in new property tax revenue for the governments.

Less Dependence on Fossil Fuel

Electricity generated from alternative energy sources helps reduce a region’s spending on coal and natural gas imports. This helps local economies save both their expenditure and the environment.

Stability in the Energy Prices

Besides providing affordable electricity to consumers across the country, alternative energy can significantly help stabilize energy prices in a region.

When it comes to alternative energy, Tampa has all the right elements to play a more decisive role in the country’s journey toward a greener future. It is, therefore, crucial for the policymakers to consider renewable energy as a catalyst to stimulate the local economy. People in this sun-bathed city should come forward and encourage the local administration to introduce policies geared toward utilizing the sources of renewable energy to the most.

Is Global Warming a Hoax?

static1.squarespace.com

As winter grips the Northern Hemisphere and record cold snaps blanket the region in snow and ice, it’s difficult to imagine a phenomenon such as global warming. Of course, even as temperatures plunge north of the Equator, Australia is engulfed in a drought with catastrophic wildfires sweeping across the continent. Environmentalists place the blame squarely on global warming caused by greenhouse gases and increased emissions associated with humans. Global warming is the excuse for any number of unexplained phenomenon in the environment.
Species extinction, climate change, shrinking polar ice caps are all blamed on global warming by environmentalists misquoting scientists who use anecdotal and sloppy research. The fact is global warming is occurring; however no one is quite sure shy. Whether the mild temperature increase is a direct effect of humans is highly doubtful. The reason is not enough evidence exists to support any one theory over the other. Average temperatures are increasing by less than one degree per decade.
This increase could be a cycle the planet has gone through several times in its four billion year history. Fossil records indicate tropical plants and climates in areas that now are buried under snow and ice for nine months out of the year. A miniature ice age occurred around medieval times, which some postulate is one of the causes of what is called the Dark Ages.
The geological record indicates many ice ages have occurred and that they do happen with some frequency. If scientists are basing their theories on recorded temperatures, then they will find temperatures are increasing. Consistent recorded temperatures only go back just over one hundred years.
Future scientists will more than likely record a decline in average temperatures and give environmentalists an excuse to blame global freezing. It’s hard to focus on era’s lasting hundreds of years when faced with the immediate threats that are blamed on global warming. Increased iceberg activity can impact shipping lanes, which can affect delivery of food and goods around the world.
Decreased habitat and changes in the environment kill off species, thousands of insects and reptiles that haven’t been discovered yet, or the more visible victims, like polar bears, which look cute and cuddly, but are actually pure predators. Environmentalists have championed global climate change as the cause for cannibalistic behavior among the bear population. It’s a great method of generating publicity despite the falsehood it promotes.
Bears will eat bears because they are carnivorous, not because of climate change. No one has demonstrated that seal populations, a source of food for polar bears, has been affected yet. Environmentalists cling to the yet, because a worst-case scenario draws a lot of attention to the cause, which is combating global warming. Global warming is not a hoax and the environmental impact is quite serious.
But blaming humans for the phenomenon is incorrect. However, no matter what the cause, the effects on global warming will need to be addressed and only humans can correct it. Through conservation efforts, and an increased movement toward renewable energy sources, global climate change can be slowed or averted.

Global Warming And Electricity Generation

Let’s be quite clear about one thing: an individual working on their own can do virtually nothing to slow global warming. Thankfully, however, humans are social animals and the normal way of living is to work together and co-operate with each person contributing some, complementary, skills in order to compete tasks that are much bigger than any one individual working on their own could achieve.

Assuming you are reading this at home, have a look round the room. Absolutely everything in that space and the place that it occupies is there because of individual choice. Now go ask a neighbour if you can look round one of their rooms (or imagine a neighbour’s room you have been in). Does it look identical? Chances are it will not. It may look pretty similar but even if it contains the same objects, they will most likely be of different colour, material and place of manufacture. Things will be arranged differently, if it is a living room the chairs and settees will have different number of sitting places. Yet everything in that room, and its location, is there as a result of individual choice. Each human is genetically different from the other and the way we dress and furnish our homes bears witness to our individuality (although we sometime choose to give that when we join a group and wear a uniform, for example).

Now, fix your gaze onto one item in the room. Where has it come from? How it get from there to here? What is it made from? If it is made from components, where did they come from? How many people were involved in the manufacture process? How many people in the distribution process? How many workers and how many managers? What about a Sydney plumber, using a diesel powered electricity generator? Are any of these things affecting the bigger picture with Global Warming – whatever that is.

All of them will have exercised some choices to find themselves in the situation where there actions and their decisions have made it possible for you to look at that object now. Truth is: modern human civilisation under capitalism is an amalgam of individual decisions that combined makes an amazing feat of managing complexity, of collaboration and of getting things done.

When we study history that is exactly what we study: his story. The study of history is to study the role and contribution of men and women and how they have shaped the course of the world. For virtually all of history is the study of the actions of individuals and how they have shaped the response of those around them. To understand how and why they made such decisions we usually read the biographies and auto-biographies of great people and many try to emulate them. But for every documented shaper of history there are thousands, maybe millions of undocumented ones that have just as powerful a role for they have influenced their friends and contributed to the growth of a “trend”. Trends are those unknowable, unseeable and unpredictable energies that shape how our societies evolve. No one is in charge yet we all have influence.

Earlier we looked at an object in your room and contemplated where it came from, who made it, and how it got from the originator to you. And it is here that the great mystery of the marketplace occurs. What would have happened if you had not bought it? Maybe someone else would have bought it maybe they wouldn’t have. And the response of the original producer (and those who handled it in its journey to you) is dependent on your decision. Because we are similar and like to get into groups, we influence each other in our behaviours and our choices. Some things are clearly accepted, something things are clearly not. The same thing happens with products and services. Each time we make a decision to buy or not to buy, we send a tiny whisper back to the producer and to our friends. When the choice is positive, that tiny whisper says “I like that, make more of them”: when the choice is to reject, the whisper says “nice try and I hope you find some other mug to take that stock from you”. When other individuals make their choices, the whisper grows to being the roar of the market and the producing company will respond accordingly. Business is a tough game and it does take a certain bunch of characteristics to be successful at it.

So, if our modern civilisation is a miracle of organisation and communication, how come we face the problem of global warming and the resultant climate change?

The answer to this might surprise you.

Politicians and governments do not control capitalism; it controls them, which is why politicians are always scared of markets. But the system itself is based on a false accounting. Our modern system is still reliant on an invention of 15th century Italian accountants: double-entry book-keeping. This system not only changed the way people did think about business activity but the way they could think. The outcome of activity was no longer in the hands of the Gods but could now be quantified and various activities compared against each other to see which was most “worthwhile”.

So powerful and complete was the concept that we still rely upon it today to drive how we account for our economic activity. Unfortunately, the world was a very different place then: we had not discovered any meaningful use for fossil fuels, there were many fewer people on the planet and the world view the inventors had was no doubt heavily influenced by Catholic doctrine, complete with man’s dominion over other life forms. Little wonder, then, that the idea that there might be a cost associated with using the Earth’s resources and services never occurred to them.

Economics is supposed to answer the question of how best humans can maximise scarce resource but the way we account for our economic activity makes the ludicrous assumption that the planet’s resources and services are not only unlimited but that there is no cost attached to their use. Had our numbers remained at the few hundred million they were when the accountancy system was developed, we might have got away with that assumption. With the planet’s population now at 7 going on 9 billion, it is clear that this assumption is no longer fit for purpose. Money is the most powerful motivator humans have ever invented but unless we can bring the ecosystem together with the economy, we will continue to struggle. We will continue to run a system that encourages people to destroy the environment simply so they can “make a living”.

There are two things you can you do to change this.

First, the majority of the world’s population live in democracies and politicians listen to their electorate. Tell your representatives at a local and national level that you want them to take the problem of global warming and the resultant climate change seriously. Tell them you believe the solution is to reform the way we account for our economic activity so that people can make a living out of protecting and restoring the environment rather than from polluting it. If the don’t think that is possible, remind them that we made up the rules once before but got it wrong and that politicians are paid to find solutions to the big problems in society.

Second, remember earlier I said that your choices in the market place sent tiny whispers back to the producers and to your friends? Well, people are more likely to copy the actions of people they admire and respect and one of the quickest ways to achieve respect is to do as you say. In other words, align your actions to your words so both are sending the same message. That way you increase the chances that your behaviours are copied that the roar of the marketplace will demand a safe, clean world.

Global warming is supposedly driven by the fossil fuelled energy we use and deforestation. This means that to have an impact you need to look at your life in two ways: the food that you eat and the energy you consume.

Food production is responsible for around one third or all of the world’s greenhouse gas emissions but not all foods are equally to blame. Fossil energy is used in livestock production systems to widely differing extents, for example, broiler chicken production is the most efficient, but it still needs an input of 4 kcal of fossil energy for each 1 kcal of broiler protein produced. Milk production, based on a mixture of two-thirds grain and one-third forage, sees the energy in/energy out ratio rise to a ratio of 14:1 but the real drain on energy use is beef and lamb. Even using livestock systems mixing forage with grain feed, beef has a ratio of 40:1 for energy in to energy out. Obviously no one only eats meat for their diet but the differences in impact you can achieve are quite amazing: a diet based primarily on fruit, vegetables and pulses will have an environmental impact of around a third that of a diet containing meats. Furthermore, increasing the intake of fibre, fruit and vegetables will also have significant beneficial health benefits, reducing the risk of cardiovascular disease, some cancers and other chronic diseases. It makes sense to change the balance of your diet toward more fruit, vegetables and pulses.

The second place to look to lighten your impact and show leadership is in the energy you use. Individual energy use is nearly as unique as the genetic make up of the individual but there are three areas to examine for, in aggregate, they will be of more or less equal importance. They are, transportation, heating & lighting your home and the things that you buy (other than food, which we have just dealt with). There are a lot of guides available to help you work out what your personal emissions are but one I find quite easy to use is called One Planet Living, which shows you how many planet Earths we would need if everyone copied your behaviour.

Broadly the areas to be aware of and seek to reduce are;

Transportation: here the critical driver is the number of miles you cover and, to a lesser extent, the number of people in the vehicle. It might surprise you that a full aircraft gets about as many passenger miles per gallon as a car with two people in it. The big difference is that a flight between say London and New York will be as far as the car may travel in a year. Very simple rule: cut the miles, cut the emissions. Cycling, walking and sailing are all pretty much carbon-free activities so try and get as much of your travel as possible done with those methods.
In heating & powering your house, if you live in the UK, for example, you will use much more energy on heating your house than you will on electricity but because the fuel used to generate the electricity (which still uses a lot of coal), the electricity generates more emissions per unit. If you also consider that some of the electrical energy is wasted through in generating and distribution inefficiency, give equal priority to cutting your use of both. Best way to cut your heating bills is to insulate the roof and wall and cut drafts from windows and doors or, simply, getting used to a lower ambient temperature. As for electricity switching to a renewable energy supplier is a quick and highly impactful step, hundreds if not thousands of times more powerful than unplugging a mobile phone charger!! If that option is unavailable to you, invest in buying an energy monitor and experimenting with it to see where your biggest savings can be made.
Lastly, with the stuff you buy, realise that happiness is most often found in human interaction rather than things. This means cutting down on the physical purchases and treating yourself to some nice service based treats. When you buy “things” buy from as near home as possible and find out as much as you can on how they were made.
There maybe some people reading this who do not think the personal actions are “strong” enough: they are certainly not intended as instructions for achieving zero-carbon living. But as I said at the beginning, humans are social creatures and global warming and the resultant climate change is the biggest threat we have ever faced to the very fabric of our being. Global warming and the resultant climate change will not be solved by the privation of a few individuals. What an individual can best do to slow global warming is to lead by example, encourage others to join them and demand of our politicians the actions that will sweep up those who refuse to act.

There are solutions to global warming and resultant climate change but the way we have arranged our accounting system is tilted against their adoption. It is up to us to demand they are put in place.

Harold Forbes is Author of “How to be a Humankind Superhero: making your actions count more than a bit”.

First published in 2010 “How to be a Humankind Superhero” was described as a “fine and heartfelt piece of work” (Iain Banks, author) that “hits the elusive balance between the analytic and the practical” (Jonathan Porritt, author and environmental campaigner). The book uses the myth of Hercules to provide individuals with twelve impactful action areas to fight climate change and inspire action by politicians.
