350--What's That?

In the summer of 2007, Arctic ice began to melt far more rapidly that scientists had expected. This is when the thawing of glaciers and the spread of droughts showed global warming was a present crisis, not a future threat. This is when George W. Bush, Jr., announced global climate change was indeed a national threat. Most importantly, this is when our leading climatologists gave up a number for the red line: 350—The number of parts per million CO2 in the atmosphere. Guess what? We’ve already passed it!

At a recent talk at Wake Forest’s Center for Sustainability, author Bill McKibben discussed the inspiring global movement that he’s led to help change the world’s understanding of its’ imminent danger. He’s even spurred the reforms necessary to get the planet back to safe CO2 levels.

According to him, above 350 parts per million carbon dioxide, the atmosphere heats too much for us to have a planet “similar to the one on which civilization developed and to which life on earth is adapted.” Well….Guess where we are today? 390 parts per million…and rising two parts per million per year. Tragic, huh? At 450 ppm, climatologists claim its atmospheric suicide. In the past when carbon levels rose to that height, sea levels rose 120 feet. Digest that…if you can still breathe.

He discussed one action that fascinated me. Around the dwindling Dead Sea, Israeli activists formed a huge human 2 on their shore, and the Palestinians a 5 on their beach, while in Jordan, a huge 0 was formed, proving that, even in places with deep division, people understand that the crisis that faces us now calls for one thing: UNITY.

He pointed out that rapidly getting the world off fossil duel is the most difficult task we’ve ever undertaken as a planet. Global movements are rare things—to work across linguistic boundaries, and the enormous divide between rich and poor, is extremely difficult.

His last comment—NO ONE (especially the United States Congress) has even begun to talk about spending the kind of money the developing world needs to adapt to the changes already coming at us…even in the Copenhagen treaty.
