Global warming


8.6.2 State what is meant by the enhanced greenhouse effect (enhanced GHE).

The "enhanced greenhouse effect is an increase in the greenhouse effect caused by human activity" (Tim Kirk). When the "composition of greenhouse gases in the atmosphere" change , such as a higher concentration of carbon dioxide, the greenhouse effect is greater and the Earth becomes warmer (Tim Kirk).

*The proof of global warming: data shows the earth average temperature is increasing. the enhanced GHE is a possible cause of global warming






8.6.3 Identify the increased combustion of fossil fuels as the likely major cause of the enhanced greenhouse effect.

The main source of the enhanced green house effect is the "burning of fossil fuels" (Tim Kirk). The burning of fuels fuels releases carbon dioxide, a greenhouse gas, into the atmosphere. The increase in the burning of fossil fuels leads to an increase in the concentration of carbon dioxide in the atmosphere, which causes the enhanced greenhouse effect.
