Document Summary
Hisham zerriffi (with some slides courtesy of milind kandlikar) Ipcc 1990 - the unequivocal detection of enhanced greenhouse effect from observations is not likely for a decade or more . Ipcc 1995 - the balance of evidence suggests that there is a discernible human influence on global climate . Ipcc 2007 - anthropogenic warming of the climate system is widespread and can be detected in temperature observations taken at the surface, in the free atmosphere and in the oceans. Evidence of the effect of external influences, both anthropogenic and natural, on the climate system has continued to accumulate since the tar. Ipcc 2014 - human influence on the climate system is clear, and recent anthropogenic emissions of greenhouse gases are the highest in history. Recent climate changes have had widespread impacts on human and natural systems. The first assessment report (ipcc, 1990) was a key element in kick-starting the unfccc in 1992.
