But that's ignorant. It presumes that such variances are random. They are not. Nothing changes for no reason. Past warming/cooling cycles can all be explained by scientific factors, such as the fact that our orbit and axial tilt have changed over time. The planet has drifted further away from the sun over time. The composition of the atmosphere used to be much different. The sun's activity level changes. Some periods in Earth's history were more volcanically active than others. Ocean currents, surface reflectivity, asteroid impacts, and much more. All such things conclusively explain the various warm/cool eras in our planet's past.
The problem is that the current warming trend cannot be ascribed to any such factors. According to all of those factors, and everything we know about Earth's history, the sun, the atmosphere, etc., we should be in a stable period. And yet we're warming. Atmospheric CO2 has dramatically increased, despite no meaningful variance in volcanic activity. The difference is us. It's a fact. All the evidence proves it. All the scientists agree.
If, in the face of all of that evidence, you continue to cling to the belief that it's a hoax, it only belies one's own willful ignorance.
