30 Climate Resilience and Benefit–Cost Analysis: A Handbook for Airports AR4 and AR5 both present projections under different future climate scenarios representing different assumptions about the path of GHG emissions reductions. The three AR4 scenarios are named B1, A1B, and A2, while the four AR5 scenarios are named Representative Concentration Pathway (RCP)

State-of-the-Art Climate Measures 31 For each scenario, there are up to 32 different available models under AR5/CMIP5. Consistent with the overall averages shown in Exhibit 3-1, variations in the projections across different models (even under the same scenario)

State-of-the-Art Climate Measures 33 A primary objective of this handbook is to present methodologies for evaluating two specific types of climate events that may be particularly relevant for airports: • The increasing occurrence of high temperatures that may force airlines to impose weight restrictions on takeoffs or (in extreme cases) cancel flights entirely.
