Carbon footprints, nation by nation

Breathing Earth

kiwanjaJust in time for Earth Day: the site Breathing Earth, which is described as a “real-time simulation which displays CO2 emissions from every country in the world, as well as their birth and death rates.” The data used comes from reputable sources, although the site admits that a simulation on this scale can never be 100% accurate. Worryingly, they note that the CO2 emission levels shown are much more likely to be too low than too high. Yikes.

This is a fascinating site, and one which throws up numbers on a scale large enough to scare the best of us. Since I started writing this brief blog post, for example, the world population has risen by over 2,000 and total CO2 emissions have exceeded an incredible 760,000 tons. The United States alone was responsible for approximately 175,000 of that.

If you ever need reminding of the relentless march of global population growth, and the increasing impact that our growing numbers are having on the planet, there can’t be many sites better than this.
