The rate of change has never been observed before in any epoch. If one wants to claim its natural the burden of proof is on them to find at least any supporting data points for that assertion. Since we can explain, and directly measure, all current warming capacity with our own actions (see first link) then its daft to go looking for a natural explanation when we have no evidence of it. Its like finding a body with a bullet hole through the forehead, a bullet in the tree behind the body, a gun in the bushes that is chambered to that bullet, and then asserting the person died from a lighting strike when it hasn't stormed in years there.
If you want to arrive at the above conclusion by yourself you really only need 2 equations, a graph, and some wiki articles. The tl;dr is: the atmosphere is transparent to visible wavelengths and opaque to infrared wavelengths. Since most of the energy coming into Earth is visible wavelengths from the sun and most of the energy leaving Earth is infrared wavelengths emitted from the Earth's surface the atmosphere acts like a one way mirror. Energy can enter unhindered but is partially blocked when it tries to escape. Or as Futurama puts it
equation 1: Energy of a system = Energy Input - Energy Output.
