You've got it backwards. Natural variability isn't off-limits. It's the first thing scientists rule in or out.
They ran the sun, volcanoes and ocean cycles. Across the industrial era, those natural factors net out to essentially zero. Solar activity has actually been flat to slightly declining while the planet warmed.
The "it's all human" figure isn't a script you're forced to recite. It's the result of doing the exact analysis you say isn't allowed. Humans account for about 1.07°C of the 1.09°C the planet has warmed since the 1800s. Natural drivers: near zero.
And here's the kicker. Greenhouse gases alone would have warmed us even more. Our own aerosol pollution masked part of it. Nature didn't hide the human signal, it just isn't the cause.
Natural variability got its hearing. It lost on the evidence, not on the rules.

The problem with the climate change narrative is not that warming isn't happening, I agree we are in a warm period. The problem is that we're only allowed to say its 100% human-caused warming. In most places, there is no room for discussion about natural variability. This creates an issue where we're not discussing something honestly but with the preconceived conclusion that it's all our fault. We can solve problems if we're not working from an accurate set of facts.
