I think that the sentence means that they made the estimates assuming that the average molecule of CO2 stays in the atmosphere for 300 years while the average molecule of CH4 stays in the atmosphere for 12 years. What they're trying to say is that the CO2 we put into the atmosphere will have a much longer impact than the CH4, and so that's what causes the increase in the CO2 pie slice. This is a great graph for this blog....

"I doubt that the intention of the author was to tell us that methane is extremely unimportant relative to CO2".

Looking at other blog entries at that site let's me assume that this is exaxtly the point he is trying to make.

On the other hand, your blog post's headline hypothesis makes me doubt if your main concern with realclimate.org is about data viz.

Jan: When the title of a blog post is "The story of methane, in five charts", one would expect to be able to understand the story without scrolling through a bunch of other blog posts that aren't cross-linked.
I don't have a concern with realclimate.org. I made a post about a specific blog post that contains an inappropriate use of pie charts.

Steven: thanks for the link. I stand behind my argument that the blog post is a example of poor public communications, and claiming that dropping data is a "conservative" choice and not addressing how a pie chart is used to illustrate data that do not add up to 100 percent just strengthened my case.

As a rebuttal to deniers who claim that too much fuss is made about CO2 from cars when all these farting cows are much more dangerous, this makes sense.

Got that Kaiser? You're a "self-proclaimed" expert.


You skipped over the last 2 panels which are truly horrific - especially that bush league cut away thing in the second part. They should have made it 3d so I'd be sure it was a joke.

-10 points for style.

The author's responses are childishly defensive, quite frankly.
