AUGUST 1, 2011
We all know that we have to reduce greenhouse gas (GHG) pollution and eventually reach zero emissions. Indeed top climate scientists and biologists are telling us that reaching zero emissions is not enough – we then have to reduce atmospheric carbon dioxide (CO2) concentration from the current 394 parts per million (ppm) to 350 ppm (according to 350.org ) and thence to 300 ppm ( according to the latest science-informed 300.org ). tonnes CO2 per person.
