Are we taking global volcanic activity into account?
Yes global volcanic activity is taken into account. Large volcanic eruptions (e.g. the 1991 eruption of Mount Pinatubo in the Philippines ) inject a massive amount of aerosol material into the upper atmosphere. Volcanic eruptions of this magnitude can result in significant global cooling for 1 to 2 years until these aerosols are removed from the atmosphere. These events are very sporadic and do not have a long-term impact on climate.
