What Are the Causes of Global Warming?

The main causes of global warming have been well documented and covered in the media, however, this is at a basic surface-level, if you want to find out the true causes of global warming, you have to look beyond the obvious and below the surface.

I will, however, be firstly explaining to you what "global warming" is; Global warming is the current rise in the average temperature of the Earth's oceans and atmosphere. It is also the increase of the Earth's average surface temperature.

The main causes of global warming are due to the effect of increased concentrations of greenhouse gases in the atmosphere, such as carbon dioxide (CO2) emissions from the burning of fossil fuels to create electricity. Fossil fuels are made of dead plants and animals. Some examples of fossil fuels are oil and petroleum. Many pollutants are sent into the air when fossil fuels are burned. Some of these chemicals are called greenhouse gasses. Other forms of greenhouse gases are, water vapour, nitrous oxide and methane. Greenhouse gases trap heat and light from the sun in the Earth's atmosphere, which increases the temperature.

Another cause of global warming, is deforestation, or the cutting down or burning of forests. Forests absorb carbon dioxide and trap heat that would otherwise escape from Earth. This is a type of greenhouse effect.

Trees are 50 percent carbon. When they are felled or burned, the CO2 they store escapes back into the air. Between 25 and 30 percent of the greenhouse gases released into the atmosphere each year - 1.6 billion tonnes of carbon dioxide - is caused by deforestation. The most important direct causes of deforestation include logging, the conversion of forested lands for agriculture and cattle-raising, urbanization, mining and oil exploitation, acid rain and fire.

Now that I have mentioned the main causes of global warming, I will tell you the true causes of global warming; and this is caused by the greed of opportunity seekers, constantly on the lookout for any opportunities to exploit.

The constant need for energy to satisfy first-world countries and the Earth's growing human population has provided a huge opportunity for the above to exploit whatever, whoever and wherever they can, in order to profit.

The greed and lack of conscience of "opportunity seekers", leads them to exploit people and/or the Earth's natural resources, in order that they may profit.

The exploitation of the Earth's natural resources by "opportunity seekers" has been one of the major causes in the upset of the balance of nature and in effect, of "global warming".

Global Warming And Earthquakes

Yesterday the earth shook in both the western and eastern United States, thereby proving my dad's theory that I really should have never ever left the safe and sound Midwest. And although I found it amusing that our nearby news stations here went into Earthquake 2011! mode for a tremble that most of us barely felt, it did raise just a little panic in me concerning the number of natural disasters heading our way. (And truly who knew that there was a fault line in Virginia??. Maybe it is time for my own bamboo earthquake shelter.)

While we joked around the workplace about that darn "global warming", it in no way occurred to me that global warming could cause an earthquake. How incorrect I am! Much research has shown a definite connection between global warming and earthquakes meaning that not simply are we causing disaster from above but also from below.

So how precisely does global warming produce an earthquake? Well, by land or by sea, Paul Revere can yell that they're coming and it all begins with the melting ice caps. When the weight of glaciers and ice sheets is relieved from the earth's crust (thanks to the melting), meaning that the crust can rebound far more rapidly. And when the enormous ice sheets have melted enough to move along, they oftentimes become stuck to the ice next to them causing pressure to accumulate until they slip forward a couple of inches at a time. This movement is referred to as "stick n' slip" and although a few inches seems inconsequential, bear in mind that we're not talking about some ice cubes in a drink here. The massive weight shift can trigger earthquakes to a 7 magnitude when it lurches forward. And the "stick n' slip" isn't a rare occurrence either. The Whillans Ice Stream [the very first ice sheet observed doing the stick n' slip] moves forward twice per day with each and every slip producing tremors that could be felt 4,000 miles away in Australia.

Yet another consequence of ice melt will be the change in sea levels which causes a rise in ocean temperatures causing the water itself to expand (a process called thermal expansion). That additional water in the great blue yonder piles up and applies pressure to faults near the coastline. Not only does that mean a lot more earthquake risks, but it also affects volcanic activity (as if we didn't have enough to worry about!). A study published in Nature way back in 1997 studying the connection between sea levels in the Mediterranean and volcanic activity within the area discovered that when sea levels rose rapidly, volcanic eruptions elevated by 300%!

And, in accordance with National Geographic News, a study of Alaska's Columbia Glacier found that modest earthquakes had been much more frequent in Alaskan summers when the ice there was melting.

Even though no scientist is spouting a doomsday theory with such a huge rise in sea level that every fault line erupts globally, the evidence is mounting that global warming is causing numerous natural disasters around us. And while I can discover some humor in our response to Earthquake 2011!, underneath that is my own crust of worry and concern about the ongoing and ever-increasing impacts of global warming.

Global Warming - Purveyor of Death

Plants, trees, animals, sea, earth, rocks, sand, water, air, wind etc all these are part of nature. Nature is something that can not be created artificially and even existed when there was no human life. Nature is referred to as the natural surroundings comprising of animal and plant kingdom.

Nature provides us many resources and we are dependent upon them for our continued existence. Plants and trees are wonderful gift of nature. These provide us not only oxygen but also helps us fighting the growing demons known as pollution and global warming. Trees are responsible for absorbing carbon dioxide (CO2) and emitting oxygen into the atmosphere due to the process of photosynthesis. This unique property makes trees real saviors of life fighting against purveyor of death.

Global warming is referred to as the increased earth's average temperature.

Effects and causes of Global Warming:
Spreading of Diseases - Warm temperature is beneficial for microorganism, germs and viruses to survive and to multiply. As a result of global warming diseases are spreading day by day.

Increased Hurricanes - Average temperature of oceans is increasing like anything and this result in increasing probability of powerful, frequent and grievous Hurricanes.

Drought - Increasing temperature results in increasing the probability of drought and serious heat waves. The day is not far when there will not be any water left because of this day by day increasing rate of global warming.

Accumulation of hazardous gases in the atmosphere - Excessive releasing of green house gases is one of the main reasons of Global warming. Some of the green house gases are CO2, N2O and methane. Accumulation of these harmful gases is increasing due to the recent industrialization and unnecessary deforestation.

Hostile world for future generation - As a result of this increasing demon, the world will turn hostile for the future generation. Global warming is badly affecting not only earth but also affecting the whole ecosystem.

Ways to avoid Global warming:
Avoid using perfumes rich in CFCs - CFC is Chlorofluorocarbon and is responsible for depletion of ozone layer. Increased use of CFCs results in increasing global warming.

Make use of solar energy - Start using solar energy appliances and equipments because these are beneficial in decreasing pollution and helps saving non-renewable resources.

Grow More Trees - Trees play an important role in saving earth from warming and soil erosion. We should grow more trees in order to keep environment safe and secure.

Organic Food - Consumption of organic food helps in decreasing carbon dioxide in the atmosphere.

Say no to Polyethene Bags- Polythene is non-recyclable material and is responsible for increasing pollution. Start using paper bags, cloth bags or bags made from recyclable material in order to save environment.

Global Warming Versus Greenhouse Effect

It is evident that various changes have occurred on the earth's surface during the last century. The temperature across the globe rose by 1%within a span of 100 years and this is not great news at all. Indeed this is a matter of grave concern and is supported by the vanishing of ice and glaciers all around the world. It is believed that Global warming is the result of increase in the levels of green house gases in the earth's crust mainly caused by the sun.

What is the Green House effect?

Sun is the main source of heat and energy for the earth. The sunlight contains the electromagnetic radiations that enter the earth surface and are absorbed by the earth. This results in the formation of infrared radiations that are emitted out into the space. But the greenhouse gases like methane, carbon dioxide, trap these radiations and this results in the heating of the earth's surface. The ultimate result is the rise in the temperature of the earth leading to adverse consequences dangerous for the existence of mankind.

What are the Green House Gases?

Green house gases have been in existence on earth from thousands of years. The Industrial Revolution in the 19th century triggered the increase in the production of the gases. Carbons oxide, methane were released as a result of combustion of gas, oil and coal. It is the human activity that has been the root cause of the increasing the green house gases in the atmosphere.

What is Global Warming?

The increase in the level of green house gases makes it easier for these gases to trap the infrared radiations within the atmosphere of the earth. This has finally resulted in the drastic rise in the temperature of the earth exposing mankind to various dangers. Polar caps, ice, glaciers and snow capped mountains are melting due to the rise in the temperature.

Human beings are responsible:

It is clearly known that it is the human activity that has led to the increase of green house gases in the earth's atmosphere resulting in global warming. Small changes in the human activities can reduce the emissions of carbon and methane. Usage of natural gas, solar and wind energy can help in curbing the emissions of carbon and methane. Once we control the carbon emission, we will surely be able to curtail the production of green house gases and reduce the global warming.

Factors Contributing To Global Warming

Global warming is defined as rise in the average temperature of Earth, surface air and oceans. According to the studies conducted, it has been explained that the Earth's temperature has risen by nearly 1 degree Fahrenheit in the last 100 years. It is one of the major environmental problems today. If this situation continues, then many adverse effects may take place on earth.

Causes Of Global Warming:

Global warming can be caused due to natural calamities or human activities. Natural causes of global warming include bursting of sunspots, solar output variations, volcanic explosions and changes in the Earth's orbit. Human activities, which increase green house gases, including burning of solid waste, wood, and fossil fuels such as oil, natural gas and coal, and deforestation. Release of hydrofluorocarbons (HFCs), perfluorocarbons (PFCs), and sulfur hexafluoride (SF6) from industrial processes generates more heat than normal and gets trapped in the atmosphere resulting in global warming.

The main gases contributing to this are carbon dioxide, water vapor, methane, and nitrous oxide. These gases are largely produced by thermal power plants that burn the fossil fuels, road vehicles, and industries. Another cause is deforestation, which is caused by cutting and burning of forests for building houses and industries.

Effects Of Global Warming:

Global warming produces several effects, ranging from the effects on atmosphere, economy, and environment and also on health of human beings.

•Due to this, there is an increase in average earth surface temperature, which resulted in the melting of polar ice. Continuous melting down of glaciers can lead to floods and other natural calamities. More increase in temperature may melt the ice and results in the increase of sea level, which will submerge and immerse low lying countries and coastal areas.
•It also affected animal kingdom and some animals become extinct due to loss of their natural habitat or failure to get adapted to the rapid changes in the climate. Animals' lifestyles have changed due to changes in seasons and migrating birds changed their time of travel and also location of migration.
•Global warming also affected seasons, as there is change in season cycle, the summers are getting prolonged than the winters.
•It is quite responsible for the initiation of some new diseases. This is because, bacteria are very capable and multiply rapidly in warmer temperatures compared to cold temperatures. The increase in temperature has resulted in the increase of microbes, which cause diseases.
•Global warming is also responsible for variation in crop production, because crops are getting destroyed due to sudden change in temperatures or sudden attack of rains. Flash floods and other natural disasters also influence the crop production.
•As a result of it, the earth's atmosphere is gradually becoming unstable. This is because of heavy rains in the places where there is very less rainfall and drought in the places where there is good annual rainfall. There is also change in months of rainfall.
•Effects of global warming, such as decreased snow level, increased temperature and other weather changes will not only influence humans but also affect complete ecosystems. These changes in ecosystem may lead to extinction of species. Another consequence is Glacier retreat, which means deterioration of glaciers. This may lead to flash floods, landslides and glacier lake overflow.
•Due to this, people may suffer from infectious, vector-borne diseases like malaria and food shortages.
•Due to global warming oceans will become significantly more acidic as more carbon dioxide is trapped into water and temperature of ocean increases. This may lead to extinction of ocean animals and plants and cause hurricanes and storms.
•The polar ice caps are melted which is fresh water and when it is submerged in sea, the salinity of ocean is disturbed and causes imbalance in ocean currents.

Global warming can cause heat strokes, cardiovascular, and respiratory problems. An efficient way to reduce emission of green house gases into atmosphere is to encourage public to use renewable energy sources and conserve energy to possible extent. More advanced technologies must be developed in order to build cleaner cars and improved way to generate electricity. These methods help in minimizing global warming and also to save energy for future generations.

How Does Global Warming Affect Our Climate?

Global warming describes the increase of the earth's average temperature beginning with the Industrial Revolution in the late 18th century. Although increases to the planet's average temperature have been recorded in ice core data for millions of years, the speed and frequency of the current temperature increase has resulted in this recent heating episode being called global warming. It is attributed to the increase in the burning of fossil fuels initially for steam engines and then in the creation of electricity. Both the fossil fuel consumption and temperature rise curves have increased exponentially in the last two centuries, leading the scientific community to conclude that the use of fossil fuels is the one of the main causes of global warming. The evidence supporting this conclusion is now overwhelming, with governments, corporations and individuals realising the implications and the importance of reducing its causes.

Why is reducing fossil fuel burning important and how does global warming affect our climate? The earth's climate is defined by a complex system of meteorological elements such as temperature, humidity and rainfall that have been recorded over an extended period of time. The planet is also divided into different climatic categories, including tropical wet, mediterranean and arid to name a few. In the last two hundred years or so, changes to the planet's climate have occurred. These are predominantly attributed to global warming or the increase in average surface temperatures around the globe. The affects of global warming have significant implications for earth's climate.

Global warming actually affects the planet's climate in a number of ways. Increased temperatures are the principle cause of climate change as they cause more evaporation to occur in the oceans, resulting in more frequent and extreme rainfall events. Over land, higher temperatures can produce drier and hotter weather conditions leading to increased desertification or enlargement of current arid climate zones. Although, global warming relates to an increase in the average world temperature, different regions will experience different climatic effects. In general, most regions will become warmer and drier, however many regions will also experience colder temperatures and increased precipitation. These variances will continue to increase, resulting in uncharacteristic weather patterns with extreme events, like hurricanes and cyclones intensifying. Changing climate also has many implications for flora and fauna that have adapted to present weather conditions. Species that cannot migrate or adapt quickly enough may become extinct. Humans will also be affected, as the distribution of arable land may change, making it harder to grow crops. Extreme weather events can also endanger settlements and human lives.

One of the most concerning affects of global warming is the increased melting of polar ice caps, resulting in rising sea levels. This process actually increases global warming because less radiation from the sun is reflected by the ice back out to space. Instead more sunlight is absorbed by land and water fueling further warming and increased melting of polar ice. Climate is also affected by this process as many weather systems are influenced by ocean currents at the poles. The large volumes of melted fresh water from the ice caps can alter ocean currents potentially causing significant changes to the global climate.

To mitigate the affects of global warming on the planet's climate it is essential that the human activities resulting in this process be minimised. If global warming does not slow down, the people, animals, and plants of earth will face a host of challenges as a result of changing climate.
