Umm, well yes. At least I think so...although Al Gore and greenpeace don't agree, not to mention the IPCC......A team of MIT scientists recorded a nearly simultaneous world-wide increase in methane levels -the first increase in ten years. What baffles the team is that this data contradicts theories stating humans are the primary source of increase in greenhouse gas. It takes about one full year for gases generated in the highly industrial northern hemisphere to cycle through and reach the southern hemisphere. Since all worldwide levels rose simultaneously throughout the same year, however, it is probable that this may be part of a natural cycle - and not the direct result of man's contributions...
... One thing does seem very clear, however; science is only beginning to get a focus on the big picture of global warming. Findings like these tell us it's too early to know for sure if man's impact is affecting things at "alarming rates." We may simply be going through another natural cycle of warmer and colder times - one that's been observed through a scientific analysis of the Earth to be naturally occurring for hundreds of thousands of years...more here...
