Investigating the Anthropogenic Global Warming in Ilorin and Surroundings

Abstract

The blanketlike covering of the earth’s-near-surface-air by greenhouse gases which has made the planet to be habitable by living things, has been threatened in recent times by technological and other pollutants. British Broadcasting Corporation (BBC) statement of 6th October 2008, that the protective ozone layer is being depleted at the rate of 6% every 10 years by human activity, is a matter for serious concern. The increase of the anthropogenic GHGs has trapped more heat energy in the earth’s-near-surface-air, thus causing global warming. Ilorin recorded a highest temperature of 40oC in one day of February 2005 and had an increase of 2oC over the 2003 to 2006 period. The highest pressure at Ilorin was 76mbar in 2003 and the lowest was 60.1mbar in 2004. The average variation between 2003 and 2006 was 4mbar. The windrun was not high but significant for the region, the highest recorded as 53.15m/s in 2005. The average variation in the windrun was 5m/s. By the use of multiple regression technique, equations were developed for predicting the climate change variables of maximum and minimum temperatures, pressure and windrun. The equations were found to be directly dependent on the products of the climate change variables and the coefficients to be estimated from the ANOVA. About 80% of the GHG emission at Ilorin is from automobiles. The minimal level of atmospheric carbon pollution puts Ilorin at an advantage in the Carbon – Trade. Joining the carbon market will cause the industrial world to invest by bringing environmental friendly technology and funds to Ilorin
