That's interesting and it sounds like you've been listening to Plimer because the US Geological Survey (USGS) states: "Human activities release more than 130 times the amount of CO2 emitted by volcanoes."
You may want to read this for a more balanced opinion.

Plimers assertions are just piss and wind to assist a section of government (who funds his research by the way) and are keen to progress the economy before the environment. His data is flawed.
Climate change is myriad of things, but it is not just colder or hotter or more rain or less rain, it's cooler and drier for longer, it's wetter and warmer for longer (extreme el nino/la nina), it's extreme weather conditions caused by internal and external forcing conditions. The issue with your 'the planet has always witnessed these climatic shifts' is that they were part of the evolution of the earth, these might be, but if not these changes are irreversible. They won't change back. I don't think the data as it stands is conclusive. Most of the ice cores and pollen record point to cooling and then coming back to an average temp. There have been extended droughts, but they have always broken, this one won't.
I'm a fence sitter until I see some conclusive data, but I'm pretty sure the burning of fossil fuels must be having an impact on our atmosphere.
