Overall, the cooling dominates; the IPCC concludes "observed stratospheric O 3 losses over the past two decades have caused a negative forcing of the surface-troposphere system" of about −0.15 ± 0.10 watts per square meter (W/m2).
Secara keseluruhan, pendinginan mendominasi; IPCC menyimpulkan "mengamati kerugian O3 stratosferik selama dua dekade terakhir telah menyebabkan pemaksaan negatif terhadap sistem troposfer permukaan" sekitar −0.15 ± 0.10 watt per meter persegi (W/m2).
