CO2 – present and past

Can you spare just four minutes to watch this (silent) video, please?

Good words thieved from the YouTube comment thread (reinventing the wheel is futile):

David Furphy: “Watch this excellent 3 minute animation  and you’ll immediately get how much Industrial Age humans have altered carbon dioxide levels in the atmosphere and how different the current level (400 ppm) is from the last eight hundred thousand years (180-280 ppm).

It also shows how the northern hemisphere, with so much more land mass and industrial activity than the southern hemisphere, appears to “breathe” carbon dioxide in and out on an annual cycle.”

Max Yekhlakov: “keep calm and carry on
we’re just returning to pre-Carboniferous levels of atmospheric carbon oxides, it is all part of the plan ;)”

Jari Juslin: “Yup. If you are an insect, lizard or algae, you have nothing to worry about!”

More on this subject (much more!) is available from NOAA (the US National Oceanic and Atmospheric Administration) and Visit for T-shirts and other useful ideas.

  1. Have you seen the film Call of Life available for a free viewing on the Top Documentary Films website? In my darker moments, I find it impossible to think that mankind will correct the harm that all of us are doing.

      No — but I shall watch it now. Thank you both for that recommendation and for the pointer to the Top Documentary Films website, which I hadn’t known of before today. And thanks also for another excuse to play with a tool I hadn’t known of before yesterday…

      ‘TDF’ looks like a really useful website. I keep meaning to try to find out what would be involved in acquiring a telly channel to do just what they’re doing (I suspect — but don’t know — that the catch would be the cost; but crowdsourcing, perhaps through might be a way to find the funds…)

      P.S. I hope you don’t mind that I inserted a couple of relevant links to your comment, Paul, as added value for the one or two folks who are mad* enough to drop by here.

      * Present company excepted, naturally ;)


I'd love to hear your thoughts...
