Abstract

Natural global climate variability and fluctuations are characteristic of the global climate and occur on both long- and shorttime scales as common phenomena. Therefore, natural influences on the global climate variability even before the industrial era may include changes in solar energy, naturally occurring water vapor and CO2 in the atmosphere, volcanic aerosol and GHG emissions, and cyclical oscillations in the oceans. However, natural variability and weather extremes, in particular local warming, influences people’s belief in climate change and their willingness to support potentially costly climate mitigation measures. Among natural sources of global climate variability, Volcanism has been a major driver of past climate variability by reflecting the incoming sunlight away from the Earth’s surface. According to different research finding, man-made climate variability in addition to natural global climate variability increase climate change from global to local level to be happen in below thirty years.
