More than 17,000 scientists have signed a petition saying human activities do not threaten to disrupt the climate. This overwhelming amount of people has been told to be wrong by one body of people. This body is our government, for many years now they have spoke of the horrendous situations stemming from global warming. This makes no sense; with the facts and information that we have received over the years they still support this preposterous idea. Humans do nothing to contribute to global warming; the irregular climate events are just natural occurrences. These occurrences are no stranger to our history either. (“Global Warm Up”)(“An Inconvenient Truth”)
The most recent case of significant warming was between the years 1850 and 1940.

Africa is used as a lead example by most supporters of global warming and what we as humans are doing to our climate. But in all reality, the facts point to a vastly different Africa from what we know of it now. Africa 1000 years ago was a drier place then it is now. This is an exact opposite of what supporters for global warming say right now. Global warming supporters say that our actions contribute to the greenhouse effect, leading to the rise in temperatures. These rises in temperatures are draining Africa’s lakes and mountain tops of liquid. This is not true; Africa was significantly drier 1000 years ago during MWP. Right now you may be asking what greenhouse gasses are, let me explain. (“Medieval Warm Period”)(“Global warming? It’s natural say experts”)(“Global warming: A natural cycle or human result?”)
Greenhouse gasses are the gasses created by humans; these gasses supposedly reduce the protection from powerful sun rays. Without the protection from these rays, the temperatures rise. There are many problems with the idea of the greenhouse effect. One major one being that greenhouse gasses are needed to sustain a habitable world. If we did not have greenhouse gasses, we would not be able to sustain life. For example the moon has no source of greenhouse gas. Because of this, the moon’s temperature fluctuates, not allowing life to form. You might be saying, only some will be okay. Not so fast! (“Global
The greenhouse effect is how the Earth naturally warms up. During the greenhouse effect, the sun radiates it heat into our atmosphere. From there, most of the heat gets trapped in the Earth’s surface, which is later released back into our atmosphere. At the lower atmosphere, water vapor and carbon dioxide are the gases that absorb most
They are known to have effects that harm the Earth and scientist use these harmful effects to “prove” that “global warming” may be real. Greenhouse gases are gases that trap heat in the atmosphere by the greenhouse effect. This is known to be a bad thing, but scientific evidence has proven that this is both a good and a bad thing. Greenhouse gases change the temperature of the Earth making Earth’s surface temperature both warmer and cooler depending on the amount of greenhouse gases in the atmosphere (Overview of Greenhouse Gases). Without greenhouse gases, the Earth would be a very cold place, the average surface temperature of Earth would be about zero degrees Fahrenheit. Due to the temperature being zero degrees, all the water on Earth would freeze and turn into ice (Overview of Greenhouse Gases). If the Earth’s surface temperature was this low, Earth would not be essential for life. This shows that the positive effects of greenhouse gases being released into the atmosphere outweigh the negative effects and leads us to believe that “global warming” is not a severe problem.
In the world today, global warming and climate change are one of the main issues with the earth. This issue affects everyone and everything in this world, and even though it seems to be a big problem, most people do not seem to care. The most familiar term is global warming and climate change, but greenhouse gases is one of the main causes and is never mentioned. Greenhouse gases are gases that absorb and emit radiation in the atmosphere, hence makes the earth warmer. The importance of this knowledge of greenhouse gases is so the world will know one of the main causes of global warming and climate change and possibly some
The definition given by NASA of global warming is “the average global surface temperature increase from human emissions of greenhouse gases.” On the subject of global warming, the key terms that applies is greenhouse gases. The title “greenhouse gas” comes from the idea that the chemicals that people use to run a greenhouse are also very common in our own atmosphere. A few of these chemicals include carbon dioxide and methane. Global warming is mainly caused by an excessive amount of greenhouse gases and creates environmental problems that affect not only temperatures, but can also disrupt many animal habitats and their way of life.
The greenhouse effect is when the heat from a planet's air warms the planet's surface to a temperature above what it normally would be without its air. What causes the greenhouse effect is that energy comes from the sun and reflects off of the earth’s surface and then goes back to the atmosphere as a bunch of heat. It affects the Earth by making the atmosphere warm.
NGS integrates greenhouse into other major policy initiatives, such as the Natural Heritage Trust, and launches new measures to increase greenhouse emission reduction activities across the Australian community. It provides the strategic framework for an effective greenhouse response and for meeting current and future international commitments. It will provide a fresh impetus for action by governments, stakeholder groups and the broader community and set directions for that action into the next century.
The greenhouse effect refers to radiation from the sun as it warms the earth. This is caused by the presence of several greenhouse gases, carbon dioxide being one of them. Carbon dioxide is formed when carbon compounds undergo oxidation reactions. Carbon dioxide helps confine heat in the earth’s atmosphere as it reflects from the sun to the earth, and thus contributes to the
Researches reveal that natural events as well as human related activities contribute to changes in average global temperatures. AtKisson affirms that global warming is basically a result of increased emission of greenhouse gases into the atmosphere. This atmospheric carbon dioxide (co2) comes from anthropogenic (caused by humans) sources. The concentration of greenhouse gas carbon dioxide, nitrous gases, and methane in the atmosphere has increased evidently due to human activities since 1800. NASA’s article adds:
Humans are polluting our atmosphere causing the Greenhouse Effect. What’s the Greenhouse Effect? “The Greenhouse Effect can be visualized as follows: imagine that Earth has been encircled by a giant glass sphere. The heat of the sun penetrates through the glass. Some of the heat is absorbed by the Earth, and some is radiated back towards space. The radiated heat reaches the glass sphere and is prevented from dispersing any further”(Global Warming The Facts). This makes the heat bounce back towards the Earth, which heats it up tremendously.
Global warming can be defined more precisely by this quote: “Without the greenhouse effect, the planet would be too cold to support life. Over time, the amount of greenhouse gases trapped in Earth’s atmosphere has increased significantly, causing worldwide temperatures to rise” (“Global Warming and Climate Change”). The greenhouse effect traps heat throughout the globe; thus warming the world at an alarming rate. One type of greenhouse gas is methane. “Methane, for example, is a greenhouse gas that is twenty-one times as potent as carbon dioxide.” (“Global Warming and Climate Change”) Methane is more harmful to the environment because plants cannot absorb it and turn it into oxygen, plants can only absorb carbon dioxide.
The natural greenhouse effect is a condition that allows for the planet to keep some of the heat from the sun trapped in the Earth’s atmosphere. The heat that remains trapped in the atmosphere comes from infrared radiation. While some heat does escape, the natural greenhouse effect helps to maintain the temperature levels on Earth and without the greenhouse effect, the temperature would drop to a temperature unable to for life to survive. Humans have added to the natural greenhouse effect by petroleum production requiring fossil fuels, powering buildings and homes as well. Natural gas, coal and oil are some of the major fossil fuels being used to power all these things that we have grown dependent on as a society. Additionally, cutting down trees for the development of land has also produced large amounts of greenhouse gases in addition to farming and our waste contributing as well.
Greenhouse gases are a main reason for climate change, but many people have a vague idea of how they work and what they do to contribute to the Earth’s rising temperature. Marc Lallanilla of Live Science writes in the article Greenhouse Gas Emissions: Causes and Sources of how the
The greenhouse effect is what allows life on Earth and the atmosphere contains trace gases which are designed to retain heat. The gases that are present in the atmosphere are water vapor, carbon dioxide, methane, ozone, and nitrous oxide. These gases act as a global insulator and help control the Earth’s atmosphere. It all begins with sunlight which is a form of energy that is mostly absorbed by land, oceans, and a portion of the sunlight is reflected back to the atmosphere. Once the earth warms up, it then gives off energy in a different form which is called infrared radiation or electromagnetic radiation. The planet need some of the greenhouse gases because without them the
Greenhouse gases are compounds in the atmosphere that can trap and hold extra heat, which increases the temperature in the atmosphere. Greenhouse gases is the cause of the greenhouse effect that leads up to global warming. The greenhouse effect is the trapping of the sun’s warmth in the lower atmosphere that is due to the visible radiation from the sun. The solar radiation reaches the Earth’s atmosphere, then the rest of the sun's energy is absorbed by the oceans and lands which result in the heating of the Earth. After that the heat from the Earth goes towards space, some of the heat is trapped in the atmosphere by greenhouses gases which make the Earth warm enough to tolerate living life. The burning of fossil fuels and land clearing start to increase the number of greenhouse gases which travels into the atmosphere. The result of trapping extra heat cause the Earth’s temperature to rise. Scientist's has proven that the constant increase of heat in the atmosphere is caused by humans. The reason humans are proven guilty for the increase of global warming is because of the amount of carbon that is put into the atmosphere. Carbon is released from burning coal, oil, and gas or cutting down and burning forests. Carbon (CO2) is known as the main source of heat-trapping gas which is mainly responsible for the increase of warming over the years. The removal of trees is another cause of global
There are two meanings of the term "greenhouse effect". There is a "natural" greenhouse effect that keeps the Earth 's climate warm and habitable. There is also the "man-made" greenhouse effect, which is the enhancement of Earth 's natural greenhouse effect by the addition of greenhouse gases from the burning of fossil fuels (mainly petroleum, coal, and natural gas). In order to understand how the greenhouse effect operates, we need to first understand "infrared radiation". Greenhouse gases trap some of the infrared radiation that escapes from the Earth, making the Earth warmer that it would otherwise be. We can think of greenhouse gases as sort of a "blanket" for infrared radiation-- it keeps the lower layers of the atmosphere warmer, and
