350 - What does it mean? Whether you are a man or a woman or a child or a Muslim or an atheist or a Christian, the number is important because it is the highest amount of carbon dioxide in parts per million that the planet can withstand before it causes irreversible damage.
This number is, for all practical purposes, the point of no return.
Unless you've been living in a cave for the past decade, you know that global warming, or climate change as the politicians like to call it now, is a serious issue that is finally getting some recognition. Unfortunately, the powers that be are not acting fast enough to reverse the tide of damage that is already occurring – disappearing glaciers, dying coral reefs, the melting of Greenland's ice, more intense hurricanes – and is sure to get much worse if we don't act FAST! We have to get back to three hundred fifty as quickly as possible and there's only a very short window of time left to do it.
