The analysis and evaluation of the relation between road transportation and climate change

摘要

The target of this article is to analyse and evaluate the relation betweenudroad transportation and climate change, through the long time series ofudaverage CO2 concentration in the atmosphere and global averageudtemperature of Earth. This article is built on data from the ageud% of which has informationudbefore the human impact on Earth. It can be clearly seen fromudthe research that the human impact on air quality has different tendencyudthan it had before. The trend of time-series was nearly independent fromudtime: it was constant. It can be identified from the data that the increase ofudtemperature was usually faster than the decrease in decreasing periods. There is a strongudcorrelation between the average CO2 concentration in air and the averageudtemperature of the Earth. The CO2 emitted into the environment increasesudthe global temperature of the Earth. A huge part of the CO2 emitted by mankindudinto the atmosphere comes from transportation, mainly from the sector ofudroad transportation.
