Morgan Bell350: a global movement
October 27th 2009 00:08
350 parts per million is what many scientists, climate experts, and progressive national governments are now saying is the safe upper limit for CO2 in our atmosphere.
We are already above the safe zone at our current 390ppm.
For all of human history until about 200 years ago, our atmosphere contained 275 parts per million of carbon dioxide.
Every year since 1992, the United Nations hosts a two-week long conference for world leaders to meet and discuss what to do to about the global threat of climate change.
In December of 2009, this meeting will be in Copenhagen, Denmark. There, delegates, non-governmental organizations, and businesses from every nation will meet to finalize a new global climate change agreement.
Just over a year old, 350 is a relatively new target being discussed in the scientific community, compared to 450ppm or 2 degrees Celsius that the Intergovernmental Panel on Climate Change supports.
At the last UN climate negotiations in Poland at the end of 2008, the 350 target began to attract more endorsers as new scientific reports and evidence of early impacts made it clear that we are already above the safe level for CO2.

The global day of action was 24th October, 2009. Photos were taken all over the world to raise awareness.
