New Scenarios Show How the World Could Limit Warming to 1.5C in 2100

New Scenarios Show How the World Could Limit Warming to 1.5C in 2100

Each world could have multiple different climate trajectories, though some will have a much easier time reducing emissions than others. The new climate trajectory associated with avoiding more than 1.5C warming in 2100 is called Representative Concentration Pathway 1.9 (“RCP1 .9”), which is a world where the radiative forcing from greenhouse gases is limited to no more than 1.9 watts per meter squared (W/m2) above pre-industrial levels. This is lower than the range of RCP s previously used by climate modellers, which went from 2.6 up to 8.5W/m2.
