The Earth Temperature And Its Effect On The Balance Between Energy Entering And Existing

Carbon dioxide (CO2) is the primary greenhouse gas emitted through human activities (“Carbon Dioxide Emissions”). In 2012, CO2 accounted for about 82% of all U.S. greenhouse gas emissions from human activities (“Carbon Dioxide

In late years, however, excess emissions of carbon dioxide and other greenhouse gases from human activities processes (mostly burning fossil fuels) have started to warm Earth's climate at a problematic rate. This has caused the global average temperature to raise, and may potentially harm many life form on earth in near future. They are generating major greenhouse gases (GHGs) which enhance greenhouse effect. This raises the global average temperature leading to climate change, and may potentially harm many life form on earth in near

But many climate scientists will tell you that this change in climate is due to humans and their activities. It is said that humans release greenhouse gases and “if emissions continue unchecked, they say the global warming could ultimately exceed 8 degrees Fahrenheit, which would transform the planet and undermine its capacity to support a large human population” (Gillis, 2015). To make it easier to understand, as sunlight reaches the Earth’s surface there are two things that can be done, one; it can either be reflected back into space or two, it can be absorbed by the Earth. Once the Earth absorbs the sunlight, it then releases some energy back into the atmosphere as infrared radiation, also known as heat. Then these greenhouse gases tend to act like a “blanket,” therefore making the Earth warmer than it would be otherwise. This process is what we call the “greenhouse effect.” The reason scientists say that climate change is caused by humans is that it’s simple, humans drive, cook food, and even heat or cool their homes, which release gases such as, carbon dioxide (CO2), methane (CH4 ), and water vapor (H2O).

Rise in global temperature: The temperature of the earth is increasing. Due to the presence or the gases like carbon dioxide, and other gases the energy are trapped into the atmosphere that causes the temperature of the earth to increase. For the last 19th century the global surface temperature has increased by 2 degree Celsius. The maximum increase in the temperature was seen in the last 35 years.

Although global temperature fluctuation does happen naturally, the main cause for the significant increase in overall temperature after the industrial revolution is believed to be caused by humans. Earth is protected and warmed by greenhouse gases in the atmosphere that prevent heat radiated from Earth from escaping into space. There are several greenhouse gases in the atmosphere, but the one responsible for global warming due to the greenhouse effect is carbon dioxide or also known as CO2.

Humans are burning fossil fuels to power their cars, their housed, etc. which emits carbon dioxide

2) (Sub-sub-subpoint) From 1990 to 2014 we have seen an increase in manmade greenhouse gas levels by 7 percent. There are 4 main greenhouse gases that we are producing: Carbon dioxide, Methane, Nitrous Oxide, and Fluorinated gases.

Greenhouse gasses in the atmosphere form the atmospheric CO2 blanket. This is formed when the sunlight that has passed through the atmosphere is radiated back towards space after it has warmed the earth’s surface. The greenhouse gasses trap this warmpth within earth’s atmosphere, by absorbing the heat energy with greenhouse gas molecules, and this keeps earth at a temeperature that can sustain life. As humans produce more greenhouse gasses, the atmospheric CO2 increases, which means more heat energy is trapped within the atmosphere causing Earth’s heat content to increase. According to the NOAA Earth System Research Laboratory, “CO2 has increased by nearly 43% in the last 150 years”. This increase in heat content causes temperatures to rise,

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:

The second main “driver” of global temperature change is reflectivity. Changes in reflectivity affect how much energy enter Earth’s system. When the sunlight reaches Earth, it can be reflected or absorbed, and that depends on the Earth’s surface and atmosphere; light colors reflect the most sunlight, while dark colors absorb more sunlight. Albedo, the amount of solar radiation reflected from an object or surface, indicates the amount of sunlight reflected as a percentage. Earth has an albedo of about 30%, which means that 70% of the sunlight is absorbed (NRC, 2010). This is important because the sunlight absorbed warms the land, water and atmosphere. In the past, this can be seen in the melting of sea ice or increases in cloud cover.

Greenhouse gases ,such as carbon dioxide, is absorb and emits heat into the earths atmosphere, keeping the Earth warm enough to support life. However, human activities, such as burning fossil fuels, are adding large amounts of greenhouse gases to the atmosphere. Earth must get rid of energy at the same rate it receives energy. More greenhouse gases means that more heat is being held in the atmosphere, which makes the temperatures higher. All the greenhouse gases people have added to the

One of the main reasons that earth’s temperatures are rising are due to greenhouse gases. Greenhouse gases are created when humans burn fossil fuels such as coals, natural gases, and oils to produce heat or electricity. These gases are then capable of trapping infrared radiation sent by the sun. Once these

The earth’s climate is predicted to change because human activities are altering the chemical composition of the atmosphere through the buildup of greenhouse gases –– primarily carbon dioxide, methane, and nitrous oxide. The heat-trapping property of these gases is undisputed. Although uncertainty exists about exactly how earth’’s climate responds to these gases, global temperatures are rising. Go to the Emissions section for much more on greenhouse gases.

The main cause for global warming can be accounted to the “human expansion of the greenhouse effect” (“A Blanket around the Earth” par. 1). Humans expand the greenhouse effect through many activities and processes: using landfills, burning fossil fuels, industrialization, deforestation, agriculture, and even the use of livestock. While it seems like these activities would not have much to do with the expansion of the greenhouse effect, they emit gases that can stay in the atmosphere for an extended period. There are gases in the atmosphere that prohibit heat from escaping; the ones that do not react to alterations in temperature “are described as ‘forcing’ climate change” (par. 2). Carbon dioxide, methane, and chlorofluorocarbons are gases whose emissions have increased due to human activities.

The earth is warmed by something called the greenhouse effect. The sun’s rays reach the Earth 's atmosphere and while some of this is reflected back into space, the rest of the sun 's energy is absorbed by the land and the oceans, heating the Earth to the right temperature. As the reflected heat is sent back into space, some of it
