Global Warming: The Gradual Rise in the Temperature of the Earth's Surface

- Global Warming Global warming is the gradual rise in the temperature of the earth's surface. The issue of global warming is multifaceted. Its effects could produce economic losses in some areas and benefit others. A small percentage of scientists, (generally in North America), will deny trends in the increase of earth's temperatures. Some will argue that increases in temperatures are not the result of human action, or that the increases will be negligible. There is no place in the public-policy debate to deny science, so these views will not be considered....   [tags: environmental issues, climate change]

Global Warming Is The Rise Of The Earth 's Average Atmospheric Temperature

- Global warming is the rise in the earth’s average atmospheric temperature. When sunlight heats the ground surface, it releases most of the solar energy it has absorbed as infrared radiation. Then what is known as the “greenhouse effect” occurs, this is where the gases in the atmosphere absorb the re-radiated infrared radiation and the escape of these gases being released into space is prevented. As long as the composition of greenhouse gases in the atmosphere does not change, the heat in the atmosphere will remain constant by releasing the contained heat into space....   [tags: Global warming, Climate change, Greenhouse gas]

Global Warming is Caused by Human Activities

- Nowadays, global warming is a term that is widely used by everyone; however most people do not know what it means. Global warming is a phenomenon for which the average temperature of the earth’s atmosphere and the oceans is increasing because of the high concentration of carbon dioxide (CO2). The rise in CO2 in the earth atmosphere has been observed since the industrial revolution began and it is projected to continue rising. According to America's Climate Choices "The average temperature of the Earth’s surface increased by about 1.4 °F (0.8 °C) over the past 100 years, with about 1.0 °F (0.6 °C) of this warming occurring over just the past three decades" (2011)....   [tags: environment, temperature]

These surges can be attributed to either man-made or pure natural occurrences. Proponents of global warming have for long believed that humans are the main reason increases in temperature around the globe is at an all-time high. These arguments are baseless as many scientific researchers have proven over time. Firstly, humans are blamed for engaging in activities that release more carbon dioxide into the atmosphere thereby depleting the ozone layer....   [tags: ozone, temperature, greenhouse]

How Heat is Transfered to the Atmosphere

- Physics textbooks define heat as the transfer of energy between a system and environment as consequences of different temperatures between them. Heat can be classified into three different types, which are latent heat, specific heat and sensible heat. These three different types of heat energy can be transferred in various ways such as through conduction, convection and radiation. The transfer of heat energy is important as it ensures that proper distribution occurs. Latent heat is defined as the heat energy expended in changing the state of a body without raising its temperature, expressed in calories per gram (a modern dictionary of geography pg 149)....   [tags: convection, radiation, temperature]

- As oil is evaporated, viscosity and oil density increases (Mishra and Kumar 2015) this can be seen from the values of viscosity for both the results for the summer and winter; the oil for the summer is more viscous than the crude weathered during the winter because of amount of volatile crude evaporated as seen in figures 15 and 25. Density for summer is less than the density for winter because more oil has been evaporated see figures 14 and 21.
