Act now or lose the battle for Earth

HUMANITY is due for another trophy. We can pat ourselves on the back because we just broke another world record: Recently, the Mauna Loa Observatory in Hawaii recorded a concentration of 415 parts per million (ppm) of carbon dioxide (CO2) in the atmosphere (bit.ly/star_carbon).

Meteorologist Eric Holthaus stated that this is a first for the planet, from even before humans ever existed millions of years ago (bit.ly/twitter_carbon).
