Global warming refers to the documented historical warming of the Earth's surface based upon worldwide temperature records that have been maintained by humans since the 1880s. It is often used synonymously with the ...view middle of the document...
32°F/decade) during the past 25 to 30 years. There have been two sustained periods of warming, one beginning around 1910 and ending around 1945, and the most recent beginning about 1976."
1.1 Definition of Global Warming
The increase of the Earth’s average surface temperature due to a build-up of greenhouse gases in the atmosphere.
Long ago the earth was conceived in a fiery blast of volcanoes and molten lava. The earth cooled and life was spawned. From the first bacterium that swam in a new ocean thru just before the industrial revolution climate, lacking any external factors has steadily changed. But since the industrialization of civilization, the climate of the earth has faced an ever growing foreign factor. This factor is the emissions of the so called “greenhouse gases” that have caused the rapid increase in world temperatures.
1.2 Causes of Global Warming
In the Intergovernmental Panel on Climate Change (IPCC) Fourth Assessment Report scientists conclude that "warming of the climate system is unequivocal, as is now evident from observations of increases in global average air and ocean temperatures, widespread melting of snow and ice, and rising global average sea level" and, furthermore, they conclude with "very high confidence (at least a 9 out of 10 chance of being correct) that the globally averaged net effect of human activities since 1750 has been one of warming" of the Earth's climate system.
For example water in a boiling pot receives heat from an element or flame and loses heat via steam and radiative cooling. As with every environmental variable, there are multiple factors that contribute to the "warmth" of the Earth. Humans’ measure warmth as temperature which is a measure of the amount of heat contained in a physical object. One can envision this concept by thinking of a pot on a stove. As heat is applied to the pot from a flame or heating element, the temperature of the pot will increase. But heat will also begin escaping the pot in the form of steam and also through radiative and convective cooling from the top and the sides of the pot. Eventually the rates of both heat loss (cooling) and heat gain (warming) may stabilize and the heat then contained within the pot at an instantaneous point of time would be reflected in an equilibrium temperature. This equilibrium temperature could be measured directly but it also could be calculated by determining all of the flux rates of heat entering (heating) and leaving (cooling) the pot.
One way that climate scientists look at the warmth of the Earth's climate system is to calculate the annual average temperature of the surface of the Earth using temperature measurements systematically collected throughout the year from thousands of land- and ocean-based weather and observation stations. The observed trend in the Earth’s annual average temperature is one of the factors leading to the scientific conclusion that the Earth is now in a period of global warming. (Source: One...
