Carbon Dioxide Levels Hit a new Record, What does the mean for the Future?

The main culprit for climate change is our emissions of Carbon Dioxide, and because of that, the rise in temperature and the rise in the concentration of carbon Dioxide in our atmosphere have been synchronously rising for decades. But, Carbon Dioxide levels have just reached a new level in, what scientist think, could be the history

of the earth, reaching 420 Parts Per Million, or PPM. So today we ask what is the science  behind measuring PPM and what do the levels being above 420 mean for the future of our Earth? To answer that I interviewed Chelsea Harvey. She is a climate change reporter for E and E News.
