Greenhouse Gases Reached Dangerous Tipping Point a Full Ten Years Ahead of Expectations
The total "long-term" carbon dioxide equivalent of greenhouse gases in the atmosphere reached 455 parts per million in 2005. (Intergovernmental Panel on Climate Change Report) It had not been expected to reach this level for a decade and is considered a tipping point.

"The amount of greenhouse gas in the atmosphere is already above the threshold that can potentially cause dangerous climate change. We are already at risk...It's not next year or next decade, it's now." (Tim Flannery, climate change expert) (1), (2).

Report from the UN Office for the Coordination of Humanitarian Affairs (OCHA):
A record number of floods, droughts and storms around the world in 2007 amounted to a climate change "mega disaster"..."We are seeing the effects of climate change. Any year can be a freak but the pattern looks pretty clear to be honest...this is here and now, this is with us already." (Under-Secretary General John Holmes) ... Two years ago only half the international disasters dealt with by OCHA had anything to do with the climate; this year all but one of the 14 emergency appeals is climate-related.... The OCHA appeals represent the tip of an iceberg since they are launched only with the agreement of the affected country. (3)

Unless we can reduce the amount of carbon dioxide in the atmosphere to 350 parts per million, we will cause huge and irreversible damage to the earth. (350.org)
