(Jan. 10 update: A few people seem to have missed the point of this satirical post. It is a counterpoint to Al Gore’s use of “millions of tons” when talking about CO2 emissions. I’m pointing out that relative to the total atmosphere, millions of tons of CO2 is miniscule. And even a 50% increase in a very small number [the CO2 content of the atmosphere] is still a very small number.)

Now that there have been 50 full years of atmospheric carbon dioxide concentration monitoring at Mauna Loa, Hawaii, I thought January1, 2009 would be an appropriate time to take a nostalgic look back.

So, without further ado, here’s what 50 years of increasing levels of CO2 looks like on the Big Island:

You can’t see it?…

here let me change the vertical scale so it runs from 0 to 10% of the atmosphere, rather than 0 to 100%….

You still can’t see it?? It’s that blue line at the bottom!

Here, I’ll change the scale…AGAIN..to go from 0 to 1% of the atmosphere….

Now can you see it? Good.
