Dear Ikhlas,

We know that the atmosphere of the Earth lets in the sunlight that warms the surface of the globe. The heat that rises from the surface is partly absorbed by the gases and water vapor present in the atmosphere - this natural process is called the "greenhouse effect". In the absence of greenhouse gases (carbon dioxide (CO2), methane (CH4) and nitrous oxide (N2O)), most of the heat entering the Earth's atmosphere would be directly re-emitted into space , and the average temperature of the Earth would be -18 ° C instead of 15 ° C. Over the last 10,000 years, the amount of these greenhouse gases in our atmosphere has remained relatively constant and has allowed the Earth to maintain a relatively stable climate. The concentration of these gases began to rise with the advent of industrialization, rising energy demand, population growth and changes in land use. The experiment, which began with industrialization, therefore consists in maintaining the increase in the atmospheric concentration of greenhouse gases by burning enormous quantities of fossil fuels (coal, oil and natural gas which generate significant amount of CO2) and further deforestation (the forest clears the atmosphere of CO2). Increasing greenhouse gas concentrations increase the natural greenhouse effect and raise the average temperature of the Earth's surface. This global warming causes climate change for all climate parameters as it triggers a change in atmospheric circulation and other subsystems of the climate system.

Continuous emission of gasses, mainly Carbon dioxide (CO2).

Thanks a lot Bachir Achour
