97% of scientists across the world have consistently shown that the current warming of the planet is anthropogenic, meaning man-made. Since the age of industrialization we have been burning carbon based fuels, coal for example, that are trapping greenhouse gasses. Thus we see a warming. The facts as we know it right now is that the planet has warmed and that burning fossil fuels is the primary cause of this event. I cannot understand how this is so difficult for the climate change deniers to comprehend. Only in America do we have such silly debates over facts!
