People who believe that global warming is mostly occuring because of human activity, it is possible that they are not completely right. The sun may have some influence on the emergence of this global environmental issue. New research presented at a recent conference of the American Geophysical Union suggested that, improvements in the instruments that are used to measure the solar impact on environment can now be used to determine how the sun itself is influencing the global warming incident. Researchers are hopeful that by measuring the sun's actual role, we can determine the role that human activity is playing. If the sun is brightening, human activity can be considered as partially guilty. This research in turn will help us to decide how much human activity will need to be controlled in order to reduce the hazardous impact of global warming.
