> Changes is solar activity (sun spot cycles) and underwater volcanic activity aren't really incorporated into the climate scientists' models, because they don't have much/any data. Temperature sensors have only recently been placed on the Juan de Fuca Ridge [1] (just off the coast of Oregon/Washington/British Columbia). The volcanic trenches in the deep ocean have no network of temperature sensors, or long-term activity data.
So you're saying that even though we have a model that works and accounts for the change in temperature BECAUSE it might be something else (of which apparently we have no measurements - no wait, we do [2]), we need to reject it?
Do we definitively not know it's Marvin the Martian firing a heat ray at us waiting for the earth shattering Kaboom? Is there a teapot floating between Mars and Jupiter whose steam is heating up our planet?
