A Carbon Quilt

I recently discovered the Carbon Quilt. It makes greenhouse gases "visible" by giving us a tangible idea of how big our emissions are. Figures like 80 million tonnes per day are obviously big, but hard to physically imagine.

The average Australian's emissions would fill a 3m cube (about the size of my bedroom) each day. An Aussie's yearly emissions would form a 3cm-thick 'quilt' more than half a kilometre wide. It get scarier when you multiply by Australia's population!

Anyway, check it out - it's especially handy if you're a visual person.
