350

350 is the number for the day. Don't necessarily play it on the mid-day or evening Pick Three, but pay attention to it.

Author and activist Bill McKibben has been focusing on that number because it represents the parts-per-million of carbon dioxide at which our climate is considered in the safe zone. Actually it represents the upper limit of the safe zone.

Currently the Earth's atmosphere is around 420 parts per million.
