Is a signature of socio-economic impact written on the climate?

Surging population associated with large-scale colonization, tropical deforestation, and industrialization in parts of Asia that constitute over 60% of the global population may lead to changes in the climate of that region. Identifying such changes is of great importance to scientists and policy makers. Concerning this, an approach is made here to assess the chemical composition in the troposphere over the region that happens to be the globe's longest belt of largest population density (LBLPD) and to assess the long term rainfall pattern of a tropical region lying along the belt of mountain ranges where an intense deforestation has been taking place on a large scale for several decades. Further, this paper reports the long term temperature and rainfall pattern of highly industriatized cities that have one of the fastest population growth rates. The tropospheric levels of CH4, CO and O-3 over LBLPD are found to be remarkably higher than those over the stations lying outside the belt. The long term rainfall data of the belt of high mountain ranges shows a significant decreasing trend, whereas the data for adjacent coastal belt, which is normally the upwind side of the mountain belt, does not show any kind of trend. Surface, air temperature and rainfall data for industrial cities with population greater than ten million shows a definite increasing trend whereas no trend is seen in data for adjacent non-industrialized towns.
