This is because when methane reductions are combined with strong actions to cut CO2, it becomes unlikely that temperatures would rise to levels that would trigger a total loss in Arctic summer sea ice.
Esto es porque, al combinar la reducción de metano con acciones contundentes para cortar el CO2, es improbable que las temperaturas puedan subir a niveles que disparen una pérdida total del hielo marino veraniego del Ártico.
