Any answer along the lines of "the Earth has warmed before" and "Mars is warming" gets a thumbs-down. I'm talking about a scientific argument to explain the current warming trend of 0.4°C over 30 years.
If you think it's a natural cycle, then explain why that's true when according to Milankovitch Cycles we should be in the middle of a cooling period

If you think it's due to the Sun, then explain why total solar irradiance has decreased slightly over the past 30 years while global warming has accelerated

If it's due to increased solar magnetic field decreasing galactic cosmic rays (GCR), thus decreasing cloud formation and warming the Earth, explain why there is no long-term trend in GCR flux

If you can't explain the warming scientifically, then how can you believe it's not being caused by humans?
