Global Warming

Global warming is known as the rising average temperatures of the surfaces of air and oceans on the earth. The cause of global warming are mostly attributed to the increasing concentrations of greenhouse gas. Greenhouse gas stimulates the greenhouse effect where a planetary surface's thermal radiation is absorbed by the atmospheric greenhouse gases (e.g., carbon dioxide (CO2), nitrous oxide, methane). The greenhouse effect is mainly the greenhouse gases containing the heat on the earth's surface, contributing to the rising temperatures.
The increasing temperatures of the earth are harmful toward several environmental systems. For example, the rising temperatures can effect the environment of certain animals, and species, causing the extinction of the organisms and creatures. The sea level rise would escalate if ice sheets and glaciers were to melt over the centuries. Several other problems have occurred, and or will occur from the result of global warming which is still transpiring today.


Greenhouse Gases and Other Factors


Greenhouse gases are gases in the atmosphere that absorbs and transmit radiation in the thermal infrared range. Naturally occurring greenhouse gases that are prominent in the greenhouse effect are water vapor, methane, ozone. Human industries have intensely contributed to the rising levels of greenhouse gases, such as the build up concentrations of methane, tropospheric ozone, nitrous oxide, and especially carbon dioxide (CO2). Carbon dioxide (CO2) concentrations have inflated as the carbon dioxide (CO2) emissions continue to rise due to the burning of fossil fuels and land-use. Another contributor towards the greenhouse effect, is in fact, not a gas at all, but clouds. Clouds also are able to absorb and emit radiation like gases.
Each greenhouse gas contribute to the greenhouse effect in various ways such as their individual characteristics or abundance. Methane is drastically stronger than carbon dioxide (CO2) as an individual greenhouse gas, but is encountered in smaller concentrations compared to carbon dioxide (CO2). Carbon dioxide (CO2) has the aptitude to evenly spread across the earth's surface, and with its enduring abundance, remains a tremendous factor in global warming.

Global Warming with Photosynthesis and Cellular Respiration


The relationship between photosynthesis and cellular respiration is the recycled carbon dioxide (CO2) between plants, the atmosphere, bodies of water, and the soil. Photosynthesis is a process exercised by organisms that can produce their own food, using light energy, H2O, and carbon dioxide (CO2) to produce glucose and O2 as waste. Cellular respiration is a process used by animals that cannot produce their own food, using glucose and O2 to produce carbon dioxide (CO2) and H2O as waste. The balance of carbon dioxide (CO2) is favorable for both living entities as they recycle carbon dioxide (CO2) for their own accommodations.
The excess of carbon dioxide (CO2) emissions generated from human actions cause a disturbance to this balance. Most of carbon dioxide (CO2) emissions come from industries, superseding transportation, residential, and agricultural CO2 emissions. Another disruption in the carbon dioxide (CO2) balance would be deforestation leading to less carbon dioxide (CO2) removal by the process of photosynthesis.

Effects of Global Warming


Global warming impacts the environment in several ways. The giant fluctuations in the temperature can lead to extinctions of entire species that are sensitive to temperature changes. Entire ecosystems can be damaged drastically from the extinction of one key organism. Imagine a symbiosis relationship between two organisms that rely on each other for their own survival; if one were to be obliterated, the other cannot live, thus both organisms have been annihilated from existence. Essentially, species that are unable to adapt to the climate changes will most likely become extinct. Weather patterns could be altered, and droughts could be more frequent from the increasing temperatures. The melting of ice sheets located in the Arctics will result in sea level rise, endangering habitants along the coasts. There are other, several problems resulting from global warming, and other, several problems that could develop.

Currently, this problem has been called to several countries' attention and motivated their efforts to lower their carbon dioxide (CO2) emissions by altering their sources for energy. Technology-wise, there are growing efforts to develop technology that are less polluting toward the environment, increasing the use of renewable energy, and increasing energy efficiency.
