Global Warming Is The Global Average Temperature Increase

Global warming is the global average temperature increase that was observed over many centuries. Scientist have determined that global warming is a result of the greenhouse effect. The greenhouse effect occurs when greenhouse gases are present in the atmosphere. These greenhouse gases are carbon dioxide, methane, nitrous oxide, water vapors, ozone, and chlorofluorocarbons. Most of these gases come from natural sources like evaporation, respiration, volcanic eruptions, and decomposition. Some gases like chlorofluorocarbons are manufactured and have been widely used as refrigerants, propellants (aerosol), and solvents. These gases absorb the sun’s light energy and then reradiate this energy. These gases absorb radiation in a unique way. A CO2 molecule absorbs an incoming infrared photon emitted from the sun. The energy from the photon causes the CO2 molecule to vibrate. Then the molecule gives up this extra energy by emitting another infrared photon. Once the extra energy has be en removed by the emitted photon, the carbon dioxide stops vibrating. The more of these gases present, the more they reradiate the sun’s energy. Because the sun’s energy is reradiated the energy is spread in all directions. This causes the surface temperature to stay in a constant range of temperature. This is the reason the temperature fluctuations are not as drastic as a planet with no and little atmosphere. The greenhouse effect only absorbs about fifty percent of the suns light energy.

There have been many opinions from an abundance of points of view on the subject. Scientists, politicians, and environmentalists have all weighed in on the debate, and each of them is passionate about their beliefs. Some issues brought about due to global warming are polar ice caps melting, glaciers receding more and more each year, and risingRead MoreGlobal Warming Case Study736 Words   |  3 Pagesthe idea of global warming becomes a more avidly discussed topic, we wanted to determine the truth on whether it is actually occurring. Therefore, we decided to complete a study where researchers analyzed the average minimum, average maximum, and average mean temperatures from the years 1948 to 2017, a period of 69 years. In each of the graphs constructed, there is a positive correlation between average temperature and years, meaning that as the years increased so did the temperatures. In figureRead MoreWhat Does Global Warming Mean?797 Words   |  3 Pages Global Warming Have you ever asked yourself what does the global warming mean? What is it caused by? According to Dictionary.com global warming means, â€Å"An increase in the earths average atmospheric temperature that causes corresponding changes in climate and that may result from the greenhouse effect.† Svante Arrhenius, the Swedish chemist who coined the term of global warming in 1896 and launched the theory, says that the burning of fossil fuels will increase the amount of carbon dioxide in theRead More Global Warming - We CAN Make a Difference Essay1251 Words   |  6 PagesGlobal Warming - We CAN Make a Difference What is global warming, and how is it affecting the Earth and its inhabitants? The greenhouse effect and global warming both correspond with each other. The green house effect is incoming solar radiation that passes through the Earths atmosphere and heats the earths surface. It absorbed much of the outgoing infrared radiation re-radiated by the Earths surface. As they absorb the infrared the atmosphere becomes warmer. The gases key to this processRead MoreGlobal Warming Is The New Epidemic1261 Words   |  6 PagesGlobal Warming is the new epidemic that is facing the United States as well as the entire world. Global Warming is the gradual increase of temperatures around the globe. The gradual rise of the average temperature of the Earth’s atmosphere and also the oceans is believed to be permanently changing the Earth’s climate. There is a debate among an abundance of people that and sometimes in the news, on whether global warming is real or not. However, scientists and climate experts all agree that theRead MoreClimate Change And The Effect Of Relative Temperatures1198 Words   |  5 PagesResults Figure 1 depicts the average minimum yearly temperature in degrees Celsius over the past 70 years to determine the presence of climate change in the city of Newark, New Jersey. There is a slight rise overall, as noted by the trend line and its positive slope. Researchers noted that there were specifically high data points from the years of 2010 to 2017, with the minimum temperature being between 8 °C to 11  °C. The highest minimum temperature observed was in 2017. It was at 11  °C, while theRead MoreGlobal Temperature And Climate Change1380 Words   |  6 PagesGlobal Temperature The Earth-atmosphere energy cycle is a structure of coordinating atmospheric components.
