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?

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.
