The Intergovernmental Panel on Climate Change (IPCC) released its First Assessment Report in 1990 as a means of taking a global initiative to study the changing climate and how to respond to these changes. Their Fifth Assessment Report, which is their most recent, was issued in 2014. The IPCC reports in its fifth assessment that they are 95 percent confident that current global warming trends are caused by humans (Cubasch et al, 2013). While the greenhouse gas effect and carbon dioxide emissions are commonly reported on, there are other, natural forcings that have effects on the global climate. A few of these natural forcings would be solar radiation, clouds and volcanoes. Solar radiation and volcanic effects have been more easily studied; however throughout the IPCC assessments clouds have contributed the largest uncertainty to understanding the global energy budget (Boucher et al, 2013). Volcanoes have existed on planet Earth since the beginning of time. It is likely that over the lifespan of the Earth that there were hundreds of thousands eruptions. There are scientists who theorize that volcanic eruptions could have been the cause for the extinction of dinosaurs millions of years
