Global climate change has always been a
big concern nationwide. Earth depends on energy that comes from sun and about
90 percent of that energy is observed by the greenhouse gasses. Greenhouse gasses
include; water vapor, Nitrous Oxide, Methane, and Carbon Dioxide. The following
gasses all contribute to the greenhouse effects.
The greenhouse gases are all molecules
composed of more than two atoms, that are sufficiently loosely to be able to
quiver the absorption of heat. Water vapor is the most plentiful greenhouse gas
compared to the other gases. Carbon Dioxide is released by natural causes of nature
such as human respiration, but is also released by burning fossil fuels and
deforestation. This increases the atmosphere in Carbon Dioxide concentration.
Methane is yet more of a dangerous greenhouse gas than Carbon Dioxide. Methane
heats the atmosphere as much as 72x more than Carbon Dioxide. The increase of
Methane will cause temperature rise, outpacing Carbon Dioxide.
A large number of human activities is changing
the natural greenhouse, causing global warming. Carbon Dioxide is a byproduct of the combustion
such as oil and coal. The energy has been used to power the whole industry, and
as burning fossil fuel grows, the more amount of Carbon dioxide is emitted to
the atmosphere. The chemical process of combustion is when O2 reacts
with glucose (C6H12O6) to produce water H2O
and Carbon Dioxide CO2. As the process of organic matter is being
burned off, the chemical energy formed in heat is being released.
Greenhouse gases absorb infrared
radiation which are long-wave heats, making greenhouse gases radiate heat energy
back to earth. This causes an increase in warm climate change. The degree of infrared radiation depends on
its temperature, the higher the temperature the more energy it gives off. About
70 percent of solar radiation passes through the earth’s atmosphere. Since
infrared radiation contains multiple wave lengths than solar radiation about 80
percent will be reflected back to earth increasing the atmosphere temperature.
Visible radiation from the sun and
infrared radiation from the atmosphere causes earth to have a higher temperature
than it should have. While heat trapping is impacted by the color surfaces of
radiation. Many regions of earth are also impacted by how the greenhouse effects
encounters. The earth’s greenhouse gasses, temperature and radiations have
great impact in Global warming.
