Quizz : vulnérabilité climatique et adaptation des exploitations agricoles
What could be the increase of average temperature on Earth if things remain the same?
The climate projections summarised in the IPCC AR5  project that global temperature will increase by mid-century (2046–2065 relative to 1986–2005), by 0.9–2.0 °C for the middle pathway (RCP4.5)
The climate projections summarised in the IPCC AR5  project that global temperature will decrease by mid-century (2046–2065 relative to 1986–2005) since greenhouse gas emmissions should decrease
Climate models project further increases in global average temperature over the 21st century (for the period 2081–2100 relative to 1986–2005) of between 0.3 °C and 1.7 °C for the lowest emissions scenario (Representative Concentration Pathway (RCP) 2.6) and between 2.6 °C and 4.8 °C for the highest emissions scenario (RCP8.5)
The global average temperature will stay below 2ºC above pre-industrial levels if emissions remain the same
