[...] Cause : increase of greenhouse gases CO? (combustion, deforestation) - CH? - N?O - H?O (feedback) Atmosphere more opaque to IR (infrared radiation) B. Associated mechanisms - Less IR escapes into space - More IR re-emitted towards the surface - Increase in emission altitude (layer from which IR can escape into space) Radiative imbalance (more energy received than emitted) Accumulation of energy in the climate system C. Consequences - Global warming of the surface - Intensification of evaporation and convection - Modification of atmospheric and oceanic circulation - Source of ice + decrease in albedo - Rise in sea level - Perturbations of ecosystems II.
