Because the changing chemistry of the ocean threatens all marine life, the nonprofit organization Oceana has invested in an advertising campaign to highlight the most urgent goal: reducing CO2 emissions to achieve atmospheric levels of 350 parts per million (ppm) or less as soon as possible.
The campaign includes signs in the Copenhagen airport, inside the Copenhagen public transit train cars, and a giant billboard that stands along the road leading the main site of the UN climate negotiations @ the Bella Center.
Metro Train Cars:
That means that every single government delegate who arrives at the UN Climate Conference in Copenhagen next week will be greeted with this urgent message - 350ppm!
If you're headed to Copenhagen and see one of Oceana's posters, then please take a photo of yourself with it, and email it to 350.org.
