Scientific data and climate scenarios

The objective of this report is to present climate change and its impacts according to two warming scenarios: the first is based on an increase in average surface temperature of 2°C by 2100, which is the most optimistic scenario established by the IPCC (RCP2.6); the second is based on an increase of 5°C by 2100, which is almost the most pessimistic scenario (RCP8.5). The physical, socio-economic and health impacts of these two scenarios are assessed for the time horizons 2030 and 2050.
