Hole in the Ozone Layer and the Greenhouse Effect
By: Karel Kosman
When discussing the preservation of our earth, two major issues are always in the forefront: the destruction of the vital ozone layer and the question of the greenhouse effect, which may be causing the increase of temperature of the atmosphere.
Ozone is an unstable gas (rather rare). It is a toxic form of oxygen. It consists of three atoms of oxygen in one molecule, while in the common molecule of oxygen there are only two atoms. Ozone is present in the entire atmosphere up to the altitude of approximately 50 kilometres. The layer containing the highest concentration of ozone (the ozone layer) is situated in the lower geographical latitudes at approximately 25 kilometres above the point zero (sea level). The altitude of the ozone layer decreases in the direction of polar regions.
By means of photochemical reaction, the short-wave part of ultraviolet rays changes oxygen into ozone. In this way, the majority of cell-damaging ultraviolet light is absorbed.
The use of chloro-fluoro-carbohydrates in sprays and manufacture of foams causes long-term damage of the protective ozone layer. The reason is, that when these gases are released, they rises very slowly into the atmosphere. There, they are dissolved by the ultraviolet light into free atoms of chlorine. They interact with ozone and destroy it. When the ozone layer is damaged, ultraviolet light penetrates to the surface of the earth. Chloro-fluoro-carbohydrates have a very long life and may continue destroying the ozone layer during many years.
This destructive process is specially noticeable at lower temperatures. A considerable decrease in the ozone layer was registered several years ago at the south pole during the winter season. This decrease is called the ozone hole. More than half of the ultraviolet rays pass through the hole. The consequence of this energy-releasing process is the release of heat. In the meantime, this effect emerged also over the north pole. In Antarctica, when at the end of the polar night the atmosphere gradually warms up again, air from the lower latitudes, rich in ozone, streams in and “fills up” the ozone hole.
In autumn of the year 2000, the hole in the ozone layer over Antarctica increased to 29 million cubic kilometres, which is four times the size of Australia. According to the information of New Zealand Antarctic stations, this increases the risk of exposure to cancer-producing ultraviolet light for the population of the southern hemisphere as never before. Antarctica as such is also threatened, because its very sensitive ecosystem may be quickly destroyed by this situation.
While the ozone in the stratosphere is being depleted, in the lower layers of the atmosphere, i.e., in the troposphere, the amount of ozone is on the increase as a result of the emissions of the automobiles (nitrogen and sulfur oxides). However, this does not help balance the decreased amounts of ozone in the stratosphere.
Even assuming that there will be a complete halt in use of the chloro-fluoro-carbohydrates, it must be taken into consideration that their damaging effects will increase. In the higher latitudes, people must take precautions and protect themselves against the ultraviolet light of the sun.
In most cases, the term “greenhouse effect” is synonymous with a negative, man-made climate change. However, without a natural greenhouse effect, the life on our planet would be impossible. The earth would remain hostile to life.
Sunlight easily passes into a greenhouse and warms it up. However, the heat cannot easily escape. That way, the heat accumulates, and that is very similar to what is going on in the atmosphere that surrounds us. It is made up of different gases: 78.1 percent of nitrogen, 21 percent of oxygen, 0.9 percent of argon, 0.03 percent of carbon dioxide, and traces of noble gases.
Fifty percent of sunlight easily reach the earth’s surface, which is heated by this sunlight. The heated earth also irradiates heat. This heat, analogous to the heat of a greenhouse, cannot easily escape through the atmosphere into the universe. It is held in the atmosphere, mostly by water vapour and carbon dioxide. These two gases absorb the heat and transfer it back to the earth.
At the present time, the mean temperature on the earth is plus 15 degrees Celsius. Without the greenhouse effect, the mean temperature would also be around 15 degrees, but it would be with the other symbol, that is to say, minus 15 degrees Celsius.
In the last few decades, people have caused the increase of the greenhouse effect. Industry, transportation and agriculture, all share in the additional amounts of the greenhouse gases being produced. These gases prevent the heat to escape into the universe, and reflect it back to the earth.
The more greenhouse gases there are, the more heat stays within the earth-atmosphere cycle. Carbon dioxide is not the only gas that increases the temperature in the atmosphere. There is also methane, which is released when forests are cleared by burning. It is also released by landfills and by many ruminants, such as beef cattle, sheep and goats. Carbon dioxide is exhaled by people and animals. It also escapes from volcanoes and is released by burning of fossil fuels. The ozone of the lower layers of the atmosphere is also one of the greenhouse gases.

How to Reuse – 10 Easy Ways to Recycle
By Mary Crowther
Published by Janet Schlarbaum
Do you want to help the environment but find that it’s too much trouble to recycle? With these easy tips, you’ll find that recycling takes a minimal amount of time to save our resources.
1. Keep a recycling bin handy and make it easy to recycle. It takes only seconds to toss an empty bottle, plastic container or can into a bin. Keep it in a nearby closet or in the garage.
2. Recycle paper. Use paper grocery bags or cardboard boxes to hold the paper. When going through the mail toss unwanted junk mail into the recycling box. Reuse blank sides of paper for notes, or grocery lists.
3. Reuse plastic grocery bags. Many grocery stores now offer an incentive to customers who bring in their own bags, offering cents off per bag. Keep the bags in the car for easy access.
4. Old bed sheets or blankets make great drop cloths for painting, arts and crafts or household repairs.
5. Spread coffee grounds and fireplace ashes in the garden to add extra nutrients to the soil.
6. Grind lemon rinds in the garbage disposal to keep it smelling fresh.
7. Plastic fruit cups can be used for small jobs around the house such as painting, cleaning or polishing.
8. Don’t throw away clothing or household items that are in good condition. Donate them to charity. Many charities will pick up your items.
9. Use plastic containers from margarine and whipped topping for leftovers.
10. Worn cotton items such as towels, washcloths or socks make perfect cleaning, dusting or polishing rags.

Our Environment, Global Warming, and How You Can Help!
By Gordon Browner
There’s no question that our planet is warming up. Average global temperatures have risen around the world in the last 100 years, especially in the past 20 years. There are many theories out there when looking for answers to this, but only two are obvious. One of those theories is the idea that the Earth naturally goes through temperature cycles during the course of its existence. Another idea is that we as humans are introducing untold amounts of carbon dioxide into the atmosphere and this is causing the planet to heat up.
Regardless of how and why Earth is warming up, it’s happening, won’t stop anytime soon, and may be dangerous in the long run. Maybe it’s human activity or maybe it’s not, nobody will be able to tell us what the exact cause is. However, what we do know is the human population most certainly contributes to the warming of the planet. The good part is we have the power to slow it down and cut our carbon dioxide output down drastically.
There are many things you can do to help our environment and cut down on your carbon footprint, all of which are reductions of energy usage at home and on the road. First and foremost, replace all the light bulbs in all your residencies to the energy-efficient bulbs. This is huge and will save you hundreds of dollars a year on your power bill, thus promoting a cleaner environment. You can also replace your old appliances with newer, energy-efficient models. The same goes for your air conditioner. These are the top 3 ways to cut your power costs at home.
There’s now a 4th and big way to reduce your carbon footprint and power bill, that is, solar panels and wind turbines you can build yourself. You can find guides and manuals online that teach you about everything you need to know. The best part about this is how simple and easy it is to construct a green energy power system in your home. Not many people know about this, but it’s a serious money saver when comparing DIY green energy to professional installations. They cost tens and tens of thousands of dollars. If you’re interested in such projects there’s a popular new site on the internet that will feed you all the information you need.
Finally, and the most effective way to reduce your carbon footprint is to avoid driving your vehicle! Walk, jog, roller blade, or bike everywhere and anywhere you can. Get that blood pumping and the savings of fuel and energy mount up incredibly fast. If you can apply multiple techniques described here, I guarantee your energy costs will drop drastically.

The Effects of Global Warming
Author: Christophe Catesson
Selected by Janet Schlarbaum
When you hear about the effects of global warming it is important to understand that the effects we are experiencing today are moderate compared to what the future will see if we do not take preventative action. Over the next century researchers and environmental professionals are stating that the effects of global warming will continue on a constant inclined curve. Temperatures heating up a little bit each decade until the earth’s temperatures reach the sweltering levels that we experienced in history. Scientists believe that the earth’s temperatures will rise between 2-9 degrees Fahrenheit by 2050.
The Arctic and the earth’s northern latitudes will feel the most of the effects of global warming as they continue to escalate. As the Arctic packs and glaciers begin to melt from the increased temperatures the tundra and seas surrounding the areas will continue to absorb the warmth which was once reflected back into space. Climate models show that if temperatures throughout the rest of the world rise to 3 degrees Fahrenheit they will more than likely rise to at least 7 degrees Fahrenheit in the Arctic. From this the oceans throughout the world will become full with melting glaciers and ice from the Arctic likely to rise by at least 3ft.
As the temperatures continue to rise this will force the ocean to evaporate quicker and therefore more rainfall will be experienced. The problem with this effect is that the rainfall may hit areas of the world which do not need it at all causing massive floods and monsoons. Subtropical areas like India are expected to be the target of this particular effect of global warming. On the other hand it is safe to say that droughts are going to be more of a problem than flooding.
There are predictions that the future effects of global warming may have its benefits as well. In the northern part of the world such as Canada, the warmer temperatures will mean longer growing seasons and more rainfall. This of course then will put an end to any food shortage that may be occurring and provide a new sense of prosperity to countries throughout the world which have been struggling to survive.
Many of the changes and effects listed above are already taking place today on a smaller scale of course. Sea levels are rising due to thermal expansion of the ocean, in addition to melting of land ice. Amounts and patterns of precipitation are changing as well but only slightly in comparison to what has been predicted for the future. Changes in temperature and precipitation patterns increase the frequency and intensity of other extreme weather events such as floods, droughts, heat waves, and tornadoes.
Other effects of global warming include higher or lower agricultural yields, further glacial retreat, reduced summer stream flows and species extinctions. As a further effect of global warming, diseases like malaria are returning into areas where they have been extinguished earlier. This is only the beginning of the effects global warming can have on our earth. As the greenhouse gases continue to increase and enter the atmosphere these effects are only going to increase in severity making it harder and harder to maintain our quality of life.
Many people find it hard to believe that the effects of global warming can become as severe as scientists are predicting but the patterns support these theories. When you read studies comparing today’s weather to weather 20years ago there are already signs proving the effects of global warming. Pay attention to the weather today and the severe weather being reported from all over the world and you will begin to see the effects within your own life as well.
We can all do our part to reduce the amount of greenhouse gases within our atmosphere. No matter how small the act might be (saving electricity, conserving fuels, etc) every action makes a difference when we are all making these eco-smart decisions. There are no doubts that the effects of global warming are only going to persist and increase if we do not do something today. The fact is that even if greenhouse emission gases were completely eliminated today it will still take years to eliminate the threats of global warming. This is why it is so important to do what we can today!

These days, there seems to be a lot of controversy about Global Warming.
Some say that Global Warming is a fact, others say it’s not. But regardless of whether or not Global Warming is a fact, let’s step aside from the arguments on the subject, and take a common-sense approach.
In this article we will take a look at some of the issues involved.
What is Global Warming?
We can take a look at the definition of global warming – without taking sides or getting into vested interests, political motivations, reasons, or causes.
The definition of global warming in its purity is “an overall increase in world temperatures.” As you can see, whether this has to do with greenhouse emissions, or whether it is caused by a natural phenomena, has no bearing on whether there is an average temperature increase.
Is There an Overall Increase in World Temperatures?
Alright, now we can take a look at what scientists say about world temperatures.
Again, we are going to leave out the reasons why, and simply look at whether or not the Earth’s general temperature is rising.
According to NASA scientists, the average temperature of the earth rose by one degree Celsius, over the last century. This is based on actual measurements taken with exact measuring instruments.
Another report, compiled and submitted by 600 scientists from the Intergovernmental Panel on Climate Change, issued the following statement:
“Warming of the climate system is unequivocal.”
These 600 scientists sifted through thousands of studies and reports, in order to come to the above conclusion.
Even scientists who are “opposed” to the global warming theory are not contradicting the fact that the earth’s temperature is rising. These scientists are only saying that global warming is a natural phenomena, and is not caused by man.
The Causes of Global Warming There are several factors that could contribute to or influence global warming.
Greenhouse gases are gases that prevent heat from escaping from the Earth’s atmosphere. A few examples of greenhouse gases are:
- Carbon Dioxide – A minor but important part of the Earth’s atmosphere. Carbon dioxide prevents heat from escaping the earth, by blocking the infrared radiation reflected off the Earth’s surface from leaving the atmosphere.
- Methane – A gas produced through the decomposition of waste (in landfills, animal waste, and decomposition of food in human and animal digestive systems). It is created by the production and distribution of natural gas, oil and coal. It is also is produced by incomplete fossil-fuel combustion.
- Nitrous Oxide – Another gas produced through the use of commercial fertilizers, natural fertilizers, and fossil fuel combustion (cars, airplanes, and conventional power plants, to name a few).
- Chlorofluorocarbons – Commonly referred to as CFC gases, these are produced primarily by our industries, and are used for products such as, styrofoam, spray-can propellants, refrigerants, electronic circuit boards, and many more.
- Water Vapor – This is a completely natural gas, caused by the sun evaporating water from our oceans.
As you can see, carbon dioxide, methane, and nitrous oxide are produced mainly by human resources, whereas chlorofluorocarbons are exclusively produced by industrial installations.
Out of all the above, interestingly enough, the greenhouse gases which have the largest effect on global warming are water vapors. This fact will no doubt please all critics of the “global warming theory”.
You have to keep in mind, however, the cyclic effect of global warming. A slight increase in temperature will increase the amount of water vapor in the atmosphere, which in turn will increase the temperature, and so on. Thus, a slight effect created by other greenhouse gases has a much larger impact, due to the creation of additional water vapor in the atmosphere.
Greenhouse gases: Facts and Figures
let’s go over some facts and figures here. Again, keep in mind that these are measurements taken by scientific tools. They are not statements for or against global warming.
- The amount of carbon dioxide in our atmosphere has increased by 25 percent since the early 1800s. Ten percent of this increase has occurred between 1958 and the present day.
- There are two main factors that responsible for the increase of carbon dioxide. The leading cause is the burning of fossil fuels. Next in line is deforestation.
- Methane content in the world’s atmosphere increases at a rate of 0.6 percent per year, by current measurements. The atmospheric methane content is now more than twice as high as it was before the Industrial Age, which started in the early 1800s.
The Effects of Global Warming
I am not the doom-and-gloom sort of person, so I am going to spare you the details here. But I do have an opinion on this subject, so I will share it with you.
Regardless of whether the globe is warming or not, it is simply common sense to take care of the environment you live in.
The plain truth of the matter is that carbon monoxide is unhealthy, methane makes for unpleasant breathing, and nitrous oxide in the atmosphere is no laughing matter.
While the lack of ozone might make for faster tanning at the beach, the long term effects are not as desirable.
What You Can do About Global Warming
Believe it or not, you are important – what you do and say is listened to by others, and does make a difference. It doesn’t require a lot of effort to do something about conditions in the environment. A little extra care will go quite a long way. Many are already doing it, and all of us need to get aboard.
It starts as simply as recycling your waste, saving energy where you can, or even planting a tree.

The fight against global warming is a full-scale war, with two strong armies poised for battle on either side. There are minor skirmishes and engagements, attacks and counter-attacks, strategies and counter-strategies, deceptions, victories and defeats. But above all, there is the fog of war – a cloud of disinformation that helps both the armies.
On one side, there is a growing number of scientists, engineers and climatologists. They are supported by some media, many celebrities, some politicians, laypersons and, surprisingly, quite a few civil servants. The latest and most powerful recruit is none other than the new US president, Barrack Obama.
Opposing them are the oil producers, automakers, processing industries, and other big businesses that want to preserve the status quo for as long as they can, to maintain their profitability. For simplicity, let us call this group the global warmers. They have the money, power and some political influence. But right now, the global warmers are on the run, facing a major onslaught from the environmental groups, and their tactics are getting increasingly defensive.
Their first line of defence is to deny the very fact of global warming. Generously funded “think tanks” produce reports that question the very accuracy of the statistical data that supports the notion of global warming. However, this position is getting less defensible as signs of global warming are now unmistakable- the break-up of the polar ice caps, the melting of glaciers and the drying up of lakes and rivers throughout the world.
The second line of defence is to deny that human beings are responsible for global warming. This again is done in reports that question the science behind the climate change models. They point out that different computer models produce different results and there is no absolute proof that human activity causes global warming. But this argument, too, is wearing thin, as more people realize that environmental pollution cannot possibly be good for the planet – it will definitely have harmful effects, most probably in the form of global warming.
The next defence -indeed a very successful one – is to steal the thunder from the opposition, by using their terminology. This gives the appearance of action when there is none, or very little. Thus every business uses words like energy efficiency, or sustainability. Any new product or service that comes out is “green”. We have green power, green politics, green communities, and green meetings.
Yet another tactic is simple diversion- moving the focus away from the issues that matter to others that have a lesser impact. Most of the environmental damage today is caused by air and water pollution from industrial sources, industrial wastes, emissions from commercial vehicles, burning of fossil fuels, depletion of natural resources, and energy consumption in large buildings. But public attention is, instead, directed towards voluntary energy savings, mostly at the individual level. We are encouraged to re-cycle more, use energy efficient light bulbs, use renewable energy, and generally reduce our environmental footprint. All these things are important but it is doubtful how much impact they will have in the absence of any real enforcement. Much more needs to be done — tightening up of regulations, more commuter trains, less buses, and reduced dependence on fossil fuels. In addition, we need stronger incentive programs to induce people to make better environmental choices.

Pre-consumer waste is the constant reintroduction of most all manufacturing scraps into the manufacturing process. Such a process is mainly used by large industries, but most of the companies using this process are not genuinely recycling. Post-consumer waste, on the other hand, is our garbage. You can reduce your post consumer waste by choosing recyclable items. This is the best way of insuring your purchases will be recycled. The more recyclable products you purchase, the more serious industries will have to reconsider their not-so-green production processes.
It is your turn to support the current recycling efforts. Purchasing products that contain post-consumer waste is a great way to start saving the environment. Doing so, will curb the constant waste of natural resources. By utilizing your purchase power for green products, you help protect virgin and natural resources which would be wasted by purchasing from a non-green company. Resources are scarce and should be treated as that. Going green should be your way of saying you don’t want to waste any resources any more.
While doing your shopping in your normal routine, make an effort to purchase products that are using recycled materials. The use of such recycled material has no effect on product itself. All it takes is the awareness of such recycled materials. When buying your groceries, check the labels to find out if the material is recyclable or not. Consider looking for the latest techniques and green gadgets in order to make sure you will be provided with recyclable materials. Search local centers that deal with the recycling process. Taking the time will help you become more aware of such products and materials. Efforts to seperate recyclable materials is always a great way to help in reusing materials. The best way to reduce your contribution to post consumer waste is by making sure no natural resources have been used in as many of the products you purchase as possible.
Becoming more aware of your ability to grow as a green shopper is the best way to reduce your carbon footprint immediately. Such purchases are cost effective as well as environmentally friendly. Going green has never been so easy and it is time you and your family become green consumers. Instilling such shopping qualities in our younger generation will help ensure our quality of life on this planet for as long as possible. Preserving our planet by avoiding post consumer waste is an easier process than it sounds. Check the labels the next time you go out, and recycle your used materials. The more resources we have in the recyclable circulation the better. Such efforts can be contagious. Certain states have incentives established to encourage recycling. Find a local recycling center near you. Make some money and go green at the same time.

With the energy crunch impacting virtually everyone worldwide today, the timing for a green building environment is just right. People have begun their own efforts to become environmentally and earth friendly, with reuse, recycle, and renew projects in the communities and on their own. It is only natural that these efforts are being extended to basics, such as building and construction activities.
Most people are familiar with green products, safe, non-toxic, recycled items such as cleaners, plastic park benches, and other conservation efforts. In buildings, you can find the green building environment at work when you see solar rooftop panels, or water barrels catching rainwater runoff for reuse in yards and gardens. Some buildings use hard packed gravel for parking lots, which will allow water absorption, instead of solid blacktop or concrete.
Some large buildings are now taking advantage of rooftop gardens and green roofs, that are planted with highly water retaining materials like moss. Or, the roofs are designed to minimize rainwater runoff. Materials for construction can be green if they include rapidly renewable plants like straw, bamboo, certified sustainable forests, recycled stone and metal. Other products used are non-toxic, or renewable or recyclable. These would include materials made from sheep wool, recycled plastic or papers, adobe brick, clay, cork, coconut or other woody fibers, sandstone, and so on. There is an effort to save on shipping and gasoline use by purchasing materials locally when possible, or nearby to the building locations.
The green building environment is seen in the manner in which buildings are constructed, as they are designed to make full use of renewable energy sources including solar and wind power. Buildings are planned for directional use of natural light and heat sources so that passive solar energy can be utilized. They are built with roofs designed to hold solar panels, with enough space facing the sunward side so that adequate amounts of panels can be installed effectively and with maximum sunlight absorption capability. Added attention is given to insulation use and special sun control on windows, as well as placement and size of windows to take advantage of passive solar heat energy.
Combinations of solar, wind and hydrogen power systems are used to get maximum benefit from naturally occurring, free, energy generating resources. Interior lighting and appliances are super efficient, using Energy Star appliances, and CFL and LED lighting, combined with automation systems. Solar heat panels for hot water can reduce water heating costs. Some buildings use solar roof tiles, to provide maximum collection of sunlight energy for generators. Indoors, the use of special filtering and air cleaners, non-smoking rules, and plants helps keep air fresher, cleaner, and less toxic.
The final component of the green building environment is to consider disposal of waste products in an environmentally friendly manner. Reduction of waste, recycling of waste, and separation facilities for reusable waste completes this earth friendly effort. With demand increasing, and prices coming down with that increased demand, this technology is a natural to spread worldwide.

According to NASA, the hottest year on record was 2005, which matched 1998. Twice in the last ten years, we’ve had the hottest temperatures on average ever recorded in our planet’s history. That is very likely more than just a coincidence.
In fact, the past nine years have all been among the 25 warmest years on record, a streak which is unprecedented in the historical record. For that to happen, it’s likely there has to be an underlying factor, and that factor seems to be global warming.
U.S. and global annual temperatures are now around 1.0 F degrees warmer than they were in 1900. The rate of warming has accelerated over the past 30 years, increasing at a rate of three times faster than the century-scale trend. It’s likely the increase in CO2 emissions has something to do with that rate increase.
According to an MIT study, there’s been a 100% increase in the intensity and duration of hurricanes and tropical storms since the 1970s, most likely due to the increased amount of CO2 emissions to our atmosphere, which has increased the Earth’s surface temperature, and warmer weather is believed to increase the intensity of tropical storms and hurricanes.
In fact, the levels of atmospheric carbon dioxide has increased by 31% between 1800 and 2000, going from 280 parts per million to 367 parts per million. Scientists predict that carbon dioxide levels could be as high as 970 parts per million by the year 2100.
According to the National Climactic Data Centre estimates, $100 billion of damage was caused by hurricanes hitting the U.S. coast in 2005 alone. The increase in severity of the hurricanes and tropical storms is most likely due to the increase of CO2 emissions, which heats up the Earth’s near-surface temperatures. In fact, the average surface temperature has increased by about 0.6 C (1.0 F) over the last 100 years. This is likely why snow cover and ice extent have decreased over the past few decades.
According to the U.S. Geological Survey predictions, Glacier National Park will have no glaciers left by the year 2030, further showing the rapidity of global warming and the impact it can have on our planet in the very near future.
According to the Arctic Climate Impact Assessment, 400,000 square miles of Arctic sea ice have melted, which is threatening polar bear habitats and further accelerating global warming worldwide. That amount of Arctic sea ice is approximately the size of the state of Texas, and we’ve lost that in just the last 30 years, further emphasizing that we need to take action now before the damage becomes too severe for our efforts to really matter.
The sea level has risen by 4?-8? (10-20 cm) over the past 100 years, which is likely due to the melting of the polar glaciers, which is likely due to the increase in the Earth’s near-surface temperature, and that’s being increased by the increase in CO2 emissions into Earth’s atmosphere. This can lead to devastating effects for coastal communities because the sea level is rising, which means that when the sea comes in-tide, more erosion can occur, and if coastal communities are present, more damage done to them. In addition, losing the glaciers reduces the amount of usable fresh water on our planet.
It is also projected that 15-37% of all plant and animal species could be wiped out by global warming by the year 2050, which could further cause considerable damage to our planet’s ecosystem.
The United States is ranked nr.1 among large nations of being a global warming polluter, contributing 25% of emissions, even though the U.S. only makes up 5% of the world’s population. This provides more evidence that the U.S. Government must do more to combat global warming. In fact, six former U.S. Environmental Protection Agency (EPA) leaders say that the U.S. is not doing enough to fight global warming. The fact that there have been NO bills passed by the U.S. Congress to cut global warming pollution further confirms what many EPA leaders are saying.
As you can see, there is statistical evidence that proves that global warming is causing changes to our planet, and changes that will do more harm than good. Governments and individuals need to pay close attention to these statistics in order to figure out ways to reverse the disturbing trends that are now occurring. The sooner we take heed of these statistics and implement changes that address global warming, the quicker we can reverse the disturbing trends and the less damage will occur to our planet and way of life.

The green-house effect is the most important cause behind global warming. In fact global warming is known as the greenhouse effect. This phenomenon leads to an increase in the Earth temperature due to certain gases like CO2, nitrous oxide, and methane. These gases trap the energy from the sun and without them the heat would go back into space and Earth would be one massive iceberg. Since these gases warm the Earth, they are known as greenhouse gases.
In the last couple of decades, people have started using glass houses to grow plants in winter and these are called greenhouses. Typically, these houses will trap the heat from the sun. The glasses in the greenhouse let the light through and at the same time prevent the heat from escaping.
As a result, the greenhouse heats up to keep the plants alive in the winter. Similarly, the greenhouse gases in the Earths atmosphere work like the glass and prevent the heat from escaping. The sunlight enters piercing through the cloud of greenhouse gases and when it reaches the Earths surface, it is absorbed by land, water, and air.
After absorption the same energy is sent back into the atmosphere. Some of it remains trapped in the atmosphere due to the greenhouse gases and this energy makes the Earth warmer. Since there has been an increase in CO2 emissions in the last couple of decades, more and more heat is being absorbed in the atmosphere. This is increasing the temperature of the Earth gradually and causing global warming.
