Abstract

Climate change is the greatest threat to people, their Survival, the Conservation of ecosystems and their Ecosystem (services). New scientific evidence reviewed in the fifth assessment report of the International Panel onClimate change (Intergovernmental Panel on Climate Change (IPCC)2013a, 2014a, b) confirmed that the average global Temperature rise is unequivocal and thus supports the assessment Intergovernmental Panel on Climate Change (IPCC)2007). Furthermore, Intergovernmental Panel on Climate Change (IPCC)2013a) highlighted that the Atmosphere and the Ocean have warmed up, the layers of snow and ice have decreased, sea level has risen and greenhouseGasEmissions of greenhouse gases (GHG)) in the Atmosphere have substantially increased due to AnthropogenicEmissions of greenhouse gases (GHG) emissions. The study also confirmed that each of the last three decades has successively become warmer than any preceding period since 1850 and that the years from 1983 to 2012 have probably been the period of the 30 warmest years during the past 1,400 years.
