Average temperaturerise by 2100

4.3°C (RCP8.5) No policy change to reduce emissions

2.8°C (RCP6.0) CO2 emissions peak in 2075, methane emissions are stable from now.

2.4°C (RCP4.5) Stringent climate policies, lower energy intensity, strong reforestation programmes . Emissions peak in 2040

Characteristics/assumptions of scenario

1.6°C (RCP2.6) Low energy intensity, Methane emissions reduced by 40%, a world population of 9 billion by 2100 – much slower population growth than in most models

The climate game may be beginning to change
