They don't dispute variations of solar heat input - something about the Earth's orbital variation over 20,000 years starts the climb out of ice ages due to increased solar input. This spurs release of greenhouse gases like CH4 and CO2, which then traps more heat, causing most of the overall heat gain involved in ending the ice age.

They don't deny that the solar increase kick starts the heat increase, so it doesn't refute them to say they have no answer to the initial lag of GHG behind temp increase.

Besides models, their theory incorporates ice core studies, biological proxies, and standard principles of chemistry and physics.

And a cathartic dose of guilt.

Please. These people are not credible! Models and theories can be manipulated to yield whatever you would like. Their whole approach - "how to answer a skeptic" - demonstrates to anyone paying attention that they are not interested in science or truth; only the defense of their climate crisis scenario. Their approach is political, not scientific. I am not impressed.
