The atmospheric CO2 concentration has risen drastically after the so-called industrial revolution. The radiative forcing associated with this increase is probably responsible for global average surface temperature increases of 0.3 to 0.6°C over the last 150 years. This is the largest warming trend at least in the last several hundred years. Global mean surface temperatures are expected to continue to rise by about 2°C late in the 21st century, when CO2 concentration will be approximately twice the current amount. Glacial melting and sea level rise have been reported to be associated with global warming, which has also been predicted to intensify the hydrologic cycle in humid regions. As a result of these, one day, the man himself would commit suicide due to un-tolerable consequences. Until then, he/she researches and implements some sort of strategies to conserve the nature for survival. Tropical inhabitants have got a big task to perform in this by conserving the environment, because the tropical forests play a major role to control the disasters by sequestering atmospheric carbon as biomass accumulations.
