Parameters used in the RCP 2.6 scenario, which limits the radiative forcing to 2.6 W/m2, included measurable factors i.e. total insured value (TIV) exposed due to the impact of acute (drought, heavy precipitation, heatwaves etc.) and chronic (changing wind patterns, heat stress, sea level rise etc.) physical climate risks based on property value and business interruption in the medium (by 2030) to long term time-horizon (by 2050). Parameters used in the RCP 4.5 scenario, which limits the radiative forcing to 4.5 W/m2, included measurable factors i.e. total insured value (TIV) exposed due to the impact of acute (drought, heavy precipitation, heatwaves etc.) and chronic (changing wind patterns, heat stress, sea level rise etc.) physical climate risks based on property value and business interruption in the medium (by 2030) to long term time-horizon (by 2050). The scenarios chosen for physical climate-related risk scenario analysis are low, intermediate and high based on the RCP 2.6, RCP 4.5 and RCP 8.5 scenarios. 111 Parameters used in the RCP 4.5 scenario, which assumes the radiative forcing increases up to 8.5 W/m2, included measurable factors i.e. total insured value (TIV) exposed due to the impact of acute (drought, heavy precipitation, heatwaves etc.) and chronic (changing wind patterns, heat stress, sea level rise etc.) physical climate risks based on property value and business interruption in the medium (by 2030) to long term time-horizon (by 2050).
