Unfortunately, "myth" describes just about all you said there. There is no 'massive' scientific debate... There is a manufactured debate, with science on only one side, so-called 'skeptics' on the other. All the planet's annual volcanic CO2 emissions about match Florida's annual CO2 emissions.
Volcanoes emit about 1% as much as humanity, even the biggest single recent eruption, Pinatubo, emitted 42 million tonnes as compared to humanity's 29 billion tonnes. I suspect you've read too much
Ian Plimer and not enough real science.
The idea of 'natural cycles' always entertains, by having no natural physical mechanism by which the current massive increase in energy stored by the planet might be happening. And they neglect that we've already observed, using the incoming and outgoing spectrum of Earth (Harries et al 2001; Philipona 2004), that this energy imbalance is due to CO2. Our CO2 emissions. So these "natural cycles" (climate elves?) need to explain both the warming and why the 100-year old physics knowledge of CO2 is uniquely not working this time!
A consequence of an increased energy content is warming and more evaporation and precipitation. Australians, as much as anyone, can see some of these consequences in exceptional extremes of precipitation, drying and temperature. It's ultimately simple physics, but with serious consequences.
