How many gigatons?

how-many-gigatons

Following yesterday’s summary of the climate change planetary boundary, here’s a visual presentation that sums things up from a slightly different perspective. From the Information is Beautiful site, it shows how many gigatons of CO2 we’ve released so far, and how much we can emit between now and 2050 and still remain within 2 degrees of warming.

On the right is the amount of CO2 banked in the world’s fossil fuel reserves – more than enough to break the planet as we know it.

We current emit 31 gigatons a year, and that number rises every year. At current rates, our carbon allowance will be gone in 13 years. The full graphic includes the consequences of overshooting the 2 degrees target, and is worth checking out.

    Dear Jeremy, for some reason I seem to have been chopped off your mailing list. Can you put me back please? Micheline

      Hi, I’m afraid I don’t manage the email list myself, it’s run through the WordPress platform. You could check that the emails aren’t going to your spam folder. Otherwise you might need to sign up again on the little form on right hand side of the blog homepage.
