IMPACT OF GREENHOUSE EFFECT GASES ON CLIMATIC CHANGES. MEASUREMENT INDICATORS AND FORECAST MODELS

The existence of a heavier layer of greenhouse effect gases at the level of theentire planet triggered significant climate changes. The paper intends to present the mainenvironmental indicators elaborated by various specialised international bodies, and themodels used by different governmental or non-governmental European bodies for studying theimpact of greenhouse effect gas emissions on climatic changes or economic development.Also, a comparative analysis was made about the performance indicators obtained by meansof differing models for forecasting greenhouse effect gas emissions by highlighting theinformation advantages/disadvantages in elaborating strategies and policies for limiting thenegative effects.Keywords: greenhouse effect gas emissions, impact, performance indicators, modelling
