Answer 1

No. Not when you consider the totals.

Here's the stuff about volcanoes. Less than 1% of what man produces, year for year.

Nature does produce a lot of carbon dioxide. And it also disposes of a lot. That's the "carbon cycle". But it's a delicate balance. We're messing it up by digging up carbon the cycle buried over many thousands of years, and burning it real fast. This graph shows the story. The little teeth are nature. Plants reduce CO2 in the summer and it rises in the winter. The big surge up is us, burning fossil fuels. The plants are clearly losing to us.

Answer 2

Wikipidia reference for some figures showing carbon cycle http://en.wikipedia.org/wiki/Carbon_cycle Yes figures with plants growing and decaying is higher but man is upsetting the balance. Volcanoes not significant in comparison to man's activities
