Milankovitch cycles, combined with positive feedback loops.
In fact, natural climate changes are caused by such things as solar variance, volcanoes, large asteroids, extreme geologic events (volcanoes, heinrich events, etc..).
Current observations eliminate all those factors from triggering present day global climate change, the only remaining cause is
likely anthropogenic. I.e., deforestation and GHG emissions.
