Agreed - C02 levels and global temperature go hand in hand but how does a sun flare create more C02 exactly? Secondly, how can you explain that C02 levels right now are significantly higher than they have been in 40,000 years on this planet? Can you actually show me the scientific nay-sayers? I looked and am having difficulty actually finding the ones that have scientific background (and are not reporters or political in nature). Sure, I've found people that debate some of the details, but nobody that says that our technology isn't adversely influencing the planet.
