Greenhouse zero-dimensional model with CO2 reduction in emission due to renewable energy use and new technologies

Atmospheric concentration of CO₂and other greenhouse gases (GHG) is higher than any time in the last 400000 years and growing faster than at any time in the past 18000 years. The high concentration of GHG generates radiative forcing that contributes to climate change. Energy production from fossil fuels has central role in regard to the climate change. . Reconstruction of the global-scale record of temperature suggests a relatively slow and steady cooling of about 0.2°C that extends from about year 1000 until the middle of 19 century; beginning in the late 19th century (since the industrial revolution ) and continuing through the 20 century, an unusually rapid warming of about 0.6°C has been taking place. Harnessing of renewable energy sources is vital to constraining the extent of climate change in global and regional level. The impact of renewable energy and new technologies in CO₂ reduction on global level is modeled and it is shown that increasing the Earth surface temperature would stop if the CO₂ reduction the next 50 years would be 80% due to renewable use and new technologies. The initial time value for this model is taken year 2005. In this model we made the degree of reduction variable due to the renewable energy use, new technology options for CO₂ reduction and policy initiatives.
